Description

Patient monitoring device and alarm method thereof

technical field

The present invention relates to the medical field, and more specifically relates to a patient monitoring device and an alarm method thereof.

Background technique

The patient monitoring equipment obtains the monitoring data of various physiological parameters (such as ECG, blood oxygen, blood pressure, etc.) of the patient, processes and analyzes the monitoring data, and presents alarm information according to the comparison between the analysis results and the alarm conditions. Providing alarm information is one of the most important functions of patient monitoring equipment, which can remind doctors and nurses to pay attention to patients and intervene according to the alarm information.

Clinically, the monitoring data of some physiological parameters may just fluctuate near the critical range corresponding to the alarm condition that meets the alarm condition. For example, a patient's heart rate fluctuates between 110 and 130, and the upper limit of the alarm threshold is 120 (unit: bmp, that is, beats/minute), when the patient's heart rate is above 120, the heart rate at this time exceeds the The upper limit is 120, and the patient monitoring equipment outputs alarm information. Whenever the monitoring equipment outputs alarm information, the doctor or nurse needs to manually click the specific function key on the monitoring equipment screen to confirm the alarm information, and the alarm information can stop outputting. When the patient's heart rate falls back to 120 and below, the alarm condition is not met at this time, and the alarm information disappears. Repeating this will cause the medical staff to confirm the alarm information frequently in a short period of time. Aversion or alarm fatigue.

In order to make the objects, technical solutions and advantages of the present invention more apparent, exemplary embodiments according to the present invention will be described in detail below with reference to the accompanying drawings. Apparently, the described embodiments are only some embodiments of the present invention, rather than all embodiments of the present invention, and it should be understood that the present invention is not limited by the exemplary embodiments described here.

In the following description, numerous specific details are given in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without one or more of these details. In other examples, some technical features known in the art are not described in order to avoid confusion with the present invention.

It should be understood that the invention can be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms "a", "an" and "the/the" are intended to include the plural forms as well, unless the context clearly dictates otherwise.

As used herein, the term "and/or" includes any and all combinations of the associated listed items.

In order to thoroughly understand the present invention, a detailed structure will be provided in the following description to illustrate the technical solution proposed by the present invention. Alternative embodiments of the invention are described in detail below, however the invention may have other embodiments beyond these detailed descriptions.

As mentioned above, when the monitoring data of physiological parameters happens to fluctuate near the alarm condition, the patient monitoring equipment will alarm multiple times in a short period of time, causing the alarm fatigue of the medical staff. In response to this drawback, there are the following strategies to reduce the number of alarms:

1. Shielding period/refractory period strategy, specifically, make the patient monitoring device no longer alarm within a period of time after an alarm occurs. This strategy can avoid frequent alarms from patient monitoring equipment, but during the shielding period/refractory period, there is no reminder about the patient's abnormal signs, and there is a risk of missing alarms;

2. The alarm delay strategy, specifically, includes two types of automatic delay entry alarm strategy and automatic delay exit alarm strategy.

Among them, the automatic delay entry alarm strategy refers to reducing transient alarms by changing alarm conditions, thereby reducing the number of alarms. However, the alarm conditions of this strategy are difficult to determine, and the performance has an upper limit: if the alarm conditions are too high, there is a risk of missing alarms; if the alarm conditions are too low, the effect of reducing the number of alarms is not obvious.

The automatic delay exit alarm strategy refers to connecting many short-duration alarms into one longer-duration alarm, thereby reducing the number of alarms, and this strategy neither affects the alarm conditions nor has clinical risks. However, this strategy ignores the actual clinical use scenarios. Although the number of alarms is reduced, the duration of the alarm will be increased. If the alarm information persists, it will not have the effect of reducing alarm fatigue, and it may be counterproductive. It will also affect medical care Afterwards, the personnel review the patient's alarm trend and reduce the diagnostic efficiency of medical staff.

To solve the above problems, an embodiment of the present invention provides a patient monitoring device. As shown in FIG. 1 , the patient monitoring device of the embodiment of the present invention includes a data acquisition module 110 , an output device 120 and a controller 130 .

Presentation method: in the process of outputting the second alarm information, judging whether the currently monitored monitoring data of at least one physiological parameter meets the first alarm condition, and judging whether the currently monitored monitoring data of at least one physiological parameter meets the first alarm condition. Two alarm conditions; if it is judged that the monitoring data of at least one target physiological parameter currently monitored does not meet the first alarm condition but meets the second alarm condition, then the control output device 120 outputs the third alarm information, wherein the second alarm condition Compared with the first alarm condition, it is easier to meet.

The patient monitoring device 100 in the embodiment of the present invention includes, but is not limited to, any one of a monitor, a local central station, a remote central station, a cloud service system, a mobile terminal or a combination thereof. The patient monitoring device 100 may be a portable monitoring device, a transfer monitoring device, or a mobile monitoring device.

The central station connects monitors in one or more departments through the network to achieve real-time centralized monitoring and mass storage of data. For example, the central station stores monitoring data, basic patient information, medical history information and diagnosis information, but is not limited thereto.

In some embodiments, the monitor and the central station can form an interconnection platform through BeneLink to realize data communication between the monitor and the central station. For example, the central station can access monitoring data monitored by the monitor. In some other embodiments, the monitor and the central station can also establish a data connection through a communication module, which includes but is not limited to WiFI, Bluetooth, NFC, ZigBee, ultra-wideband UWB or 2G, 3G, 4G, 5G and other mobile communication modules Or cable-based wired communication modules.

When the patient monitoring device 100 is a monitor, the data acquisition module 110 may include sensors connected to the monitor. The sensor and the controller 130 of the monitor can be connected through a wired communication protocol or a wireless communication protocol, so that the sensor and the controller 130 can exchange data. Specifically, the sensor is used to collect monitoring data of the patient's vital sign parameters. Among them, vital sign parameters may include but not limited to ECG, respiration, blood oxygen saturation, heart rate, pulse, body temperature, non-invasive blood pressure, invasive blood pressure, end-tidal carbon dioxide, respiratory mechanics parameters, anesthetic gas, cardiac output, EEG One or more vital sign parameters such as bispectral index.

For example, the central station can obtain the monitoring data sent by the bedside monitor and the mobile monitor through the communication module; for another example, the bedside monitor can obtain the monitoring data sent by the mobile monitor and the central station through the communication module.

The output device 120 includes at least a display, and the display is used to provide a user with a visual display output. Specifically, the display can be used to provide a user with a visual display interface, including but not limited to a monitoring interface, a parameter setting interface, an alarm setting interface, and the like. The monitoring interface displayed on the monitor is used to display monitoring data of physiological parameters. Exemplarily, the display can be implemented as a touch display, or a display with an input panel, that is, the display can also serve as an input device.

In addition to a display, the output device 120 may also include an audio output device, an indicator light, a printer, and the like. The audio output device can be used to output the alarm sound, and the indicator light can be used to light prompt information, so that the medical staff can carry out corresponding rescue measures, and can understand the patient's situation and the working status of the equipment in real time, so as to avoid the medical staff or patients from being negligent. Phenomenon, improve the security of monitoring. The information output by the output device 120 is not limited to alarm prompts, for example, the audio output device may also be used to output operation prompt sounds, power on and off prompt sounds, and the like.

In order to realize user interface and data exchange, in addition to the display 110 , the patient monitoring device 100 may also include other input devices connected to the controller 130 for the user to input operation instructions. Other input devices include, but are not limited to, keyboards, mice, trackballs, joysticks, remote controls, and the like. The input device may be used to obtain a user's alarm reset operation.

The controller 130 of the patient monitoring device 100 can be a central processing unit (Central Processing Unit, CPU), and can also be other general processors, digital signal processors (Digital Signal Processor, DSP), application specific integrated circuits (Application Specific Integrated Circuit, ASIC), Field-Programmable Gate Array (Field-Programmable Gate Array, FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. A general-purpose processor may be a microprocessor, or the processor may be any conventional processor, or the like. The controller 130 is the control center of the patient monitoring device 100 , and connects various parts of the entire patient monitoring device 100 through various interfaces and lines.

Patient care device 100 also includes memory. The memory stores program codes, and the controller 130 is used to call the program codes in the memory to execute the steps in the following display method. The memory can be used to store patient monitoring data. The memory can mainly include a program storage area and a data storage area, wherein the program storage area can store operating systems, application programs required by multiple functions, etc.; the data storage area can store monitoring data, etc. In addition, the memory may include a high-speed random access memory, and may also include a non-volatile memory, such as a hard disk, a memory, a plug-in hard disk, a smart memory card (SmartMedia Card, SMC), a secure digital (Secure Digital, SD) card, Flash Card, multiple magnetic disk storage devices, flash memory devices, or other volatile solid state storage devices.

Referring to FIG. 2 , it shows a flow chart of the patient monitoring device 100 outputting alarm information according to the embodiment of the present invention. Specifically, the controller 130 first judges whether the currently monitored monitoring data of at least one target physiological parameter meets the first alarm condition; when it is judged that the currently monitored monitoring data of at least one target physiological parameter meets the first alarm condition, The control output device 120 outputs the first alarm information. As shown in FIG. 3 , during the period from T0 to T1 , the monitoring data of at least one target physiological parameter satisfies the first alarm condition, and the control device 120 continuously outputs the first alarm information during this period.

Wherein, the first alarm condition may be a first overrun alarm condition. The first overrun alarm condition is used to monitor whether the monitoring data exceeds a certain alarm threshold. Specifically, the monitoring data meeting the first alarm condition can be that the monitoring data is greater than the first alarm upper limit threshold, or the monitoring data is less than the first alarm lower limit threshold; The range between the first alarm upper limit and the first alarm lower limit is the normal range of monitoring data. For example, the first over-limit alarm condition may include a heart rate greater than 120 bpm. When the heart rate value exceeds 120 bpm, it is determined that the monitoring data of the heart rate parameter meets the first alarm condition. At this time, the controller 130 controls the output device to output the first alarm information.

Alternatively, the first alarm condition includes a first abnormal event alarm condition. The first abnormal event alarm condition is used to monitor whether an abnormal event occurs based on the monitoring data of one or more physiological parameters. For example, the first abnormal event alarm condition may include a waveform analysis rule corresponding to the abnormal event, and the controller 130 may extract the waveform feature from the waveform curve of the physiological parameter based on the waveform analysis rule, and determine whether the abnormality corresponding to the waveform analysis condition occurs according to the waveform feature. event. For example, the controller 130 may analyze waveform curves of ECG parameters to determine whether a ventricular tachycardia event occurs. Alternatively, the first abnormal event alarm condition may include a combined alarm condition of multiple physiological parameters, for example, if the heart rate value is greater than 100bpm but less than 120bpm, the first over-limit alarm condition corresponding to the heart rate parameter is not met, but if the heart rate value is greater than 120bpm , and the arterial pressure is less than 90, and the respiratory rate is greater than 22, then based on the monitoring data of heart rate, arterial pressure and respiratory rate, it can be determined that the first abnormal event alarm condition is met.

Exemplarily, the first warning information includes at least a first warning sign displayed on the display. The first alarm identifier includes a first alarm character string, which is used to describe the cause of the alarm. Usually, the cause of the alarm is that the current monitoring data meets a preset alarm condition. Exemplarily, when the first alarm condition that triggers the first alarm information is the first over-limit alarm condition, the first alarm character string includes monitoring data representing at least one currently monitored physiological parameter meeting the first over-limit A string of alarm conditions, such as "HR too high" or "HR>120". When the first alarm condition that triggers the first alarm information is the first abnormal event alarm condition, the first alarm character string includes characters used to indicate that the monitoring data of at least one physiological parameter currently monitored meets the first abnormal event alarm condition Strings such as "VT", "HR > 100 with Art-Sys < 90, RR > 22". Of course, the above first alarm character string is only an example, and the first alarm character string only needs to be able to describe the cause of the alarm so that the medical personnel can perform corresponding rescue measures.

In addition to the first alarm character string, in order to attract the attention of medical staff, the first alarm sign can also include a graphic of a preset color and shape displayed below the alarm character string, that is, the first alarm character string can have a preset background color . For example, the first alarm identifier may include a red rectangle identifier and a white character string displayed in the red rectangle identifier. The first alarm sign can be displayed in the alarm information display area of the monitoring interface, and the alarm information display area can be located in the information bar at the top of the monitoring interface. In some embodiments, alarm details may also be displayed in response to the selection operation of the first alarm identifier.

In addition to displaying the first alarm sign, the controller 130 can also control the display to display the monitoring data of the target physiological parameter in the monitoring interface in a first highlighted manner, so that the medical staff can quickly determine the target physiological parameter and its monitoring data that trigger the alarm. Wherein, the first highlighting method includes highlighting the monitoring data of the target physiological parameter, zooming in, changing the color, adding a background color below the value, displaying a specific mark near the value, and the like.

Since the user's alarm reset operation is not obtained when the first alarm information is output, and the first alarm information is triggered by a first alarm condition that is difficult to satisfy, the first alarm information needs to have a more prominent presentation manner. Therefore, the first alarm information may also include an alarm sound output by the audio output device, and/or, the first alarm information may also include light prompt information output by an indicator light, so as to further attract the attention of medical staff.

During the process of outputting the first alarm information, the controller 130 may also acquire the user's alarm reset operation. As shown in FIG. 4 , the alarm reset operation in the embodiment of the present invention can be obtained through the alarm reset key 410 located in the monitoring interface or a physical alarm reset key, or can be obtained through other methods. For example, the alarm reset operation can also be obtained through an alarm confirmation key, an alarm pause key, a sound pause key, a sound off key, a ring tone cancel key, an alarm suppression key or a user-defined reset button. The alarm reset operation in this embodiment of the present invention may be any operation that can indicate that the user has learned the first alarm information, and is not limited to the selection operation of the alarm reset key 410 .

The controller 130 is further configured to control the output device 120 to output the second alarm information in response to the alarm reset operation. Obtaining the user's alarm reset operation indicates that the user has learned the first alarm information, but at this time the monitoring data of the target physiological parameter is likely to still meet the first alarm condition. In order to prevent the user from forgetting or ignoring the alarm and causing clinical risks, therefore, After acquiring the user's alarm reset operation, continue to output the second alarm information. However, since the user has been informed of the alarm, in order to reduce alarm fatigue, the second alarm information can be presented in a relatively weaker presentation mode, that is, the original first alarm information has a more prominent presentation mode than the current second alarm information, This makes the current second alarm information less intense than the first alarm information, and will not cause special attention, resentment or alarm fatigue of medical staff.

Continuing to refer to FIG. 3 , at time T1, the controller 130 obtains the user's alarm reset operation, and during the period from T1 to T2, the monitoring data of at least one target physiological parameter still meets the first alarm condition, and the controller 130 controls the output device 120 to output The alarm information of is changed from the first alarm information to the second alarm information.

Exemplarily, the second warning information includes a second warning sign displayed on the display. Continuing to refer to FIG. 4 , the second alarm symbol 420 may be displayed at the same display position as the first alarm symbol, both of which are displayed in the alarm information display area of the monitoring interface. The second alarm identifier includes a second alarm character string 421 and a reset response mark 422 for representing an alarm reset operation.

During the period from T1 to T2, the monitoring data of at least one target physiological parameter still meets the first alarm condition, therefore, the second alarm character string may be the same as the first alarm character string. Specifically, when the first alarm condition is the first over-limit alarm condition, the second alarm character string includes a character string used to characterize that the monitoring data of at least one physiological parameter currently monitored meets the first over-limit alarm condition, for example The second alarm string is still "HR too high" or "HR>120". When the first alarm condition is the first abnormal event alarm condition, the second alarm character string includes a character string used to characterize that the monitoring data of at least one physiological parameter currently monitored meets the first abnormal event alarm condition, such as "ventricular tachycardia ". In addition, the second warning character string and the first warning character string may have the same color and/or the same background color. Certainly, the second alarm character string and the first alarm character string may also have different colors and/or different background colors.

The reset response mark 422 may be a check mark displayed before the second alarm character string as shown in FIG. 4 , but is not limited thereto. The reset response mark 422 may be various geometric patterns or characters, which are used to indicate that the user's alarm reset operation has been obtained. The reset response mark 422 can be displayed on the left side of the second alarm string, on the right side, or above or below the second alarm string. The embodiment of the present invention does not limit the type and display position of the reset response mark.

Exemplarily, the background color of the first warning sign and/or the second warning sign may depend on the type or level of the warning. For example, the alarm levels include low-level alarm, medium-level alarm, and high-level alarm, and different alarm levels correspond to different background colors. Alarm types can include technical alarms, overrun alarms, event alarms, etc. Different alarm types correspond to different background colors. Referring to FIG. 5 , it shows the second alarm identifiers corresponding to technical alarms, overrun alarms, and event alarms, respectively.

In addition to the second alarm identifier, controlling the output device 120 to output the second alarm information may also include controlling the display to display the monitoring data of the target physiological parameter in a second highlighted manner in the monitoring interface. The second highlighting manner may be the same as the first highlighting manner, for example, both include monitoring data of the target physiological parameter displayed as a background color of an alarm level. The second highlighting method can also be different from the first highlighting method. For example, the first highlighting method includes displaying the monitoring data of the target physiological parameters as the background color of the alarm level and flashing, and the second highlighting method includes The monitoring data of physiological parameters are displayed as the background color of the alarm level, but do not flash.

There may be many ways to realize that the first alarm information has a more prominent presentation manner than the second alarm information. For example, the first alarm information includes alarm sound and/or light prompt information, while the second alarm information may only include the second alarm logo displayed on the display, that is, stop the alarm sound and/or light prompt after the alarm reset operation input by the user is obtained. information to avoid alarm fatigue for medical staff. Alternatively, both the first alarm information and the second alarm prompt information may also include an alarm sound, but the first alarm information includes an alarm sound played at a higher volume, or a faster alarm sound is played, so as to present the alarm information more prominently.

Optionally, a more prominent presentation may include more prominent visual effects. For example, the first warning sign has a higher flicker frequency than the second warning sign, or the first warning sign flickers while the second warning sign does not flash, or the background color of the first warning sign is lower than that of the second warning sign. The background color is more eye-catching, or the graphic or font of the first alarm sign is larger than the graphic or font of the second alarm sign, etc.

The controller 130 is further configured to trigger the alarm delay setting in response to the alarm reset operation, so that the alarm delay is performed when the monitoring data of at least one target physiological parameter no longer satisfies the first alarm condition. Specifically, in the process of outputting the second alarm information, the controller 130 judges whether the currently monitored monitoring data of at least one physiological parameter meets the first alarm condition, and determines whether the currently monitored monitoring data of at least one physiological parameter Whether the second alarm condition is satisfied, wherein the second alarm condition is easier to satisfy than the first alarm condition. Specifically, the controller 130 may determine whether the currently monitored monitoring data of at least one physiological parameter meets the second alarm condition when judging that the currently monitored monitoring data of at least one physiological parameter does not meet the first alarm condition. If it is judged that the currently monitored monitoring data of at least one target physiological parameter does not meet the first alarm condition but meets the second alarm condition, the output device 120 is controlled to output third alarm information. Conversely, if the controller does not obtain the user's alarm reset operation during the process of outputting the first alarm information, it can directly contact the alarm when it is judged that the currently monitored monitoring data of at least one physiological parameter does not meet the first alarm condition.

Exemplarily, the second alarm condition includes a second overrun alarm condition, and specifically may include a second upper alarm threshold and/or a second lower alarm threshold. The second alarm condition is easier to satisfy than the first alarm condition may be that the second upper alarm threshold is lower than the first alarm upper threshold, or the second lower alarm threshold is lower than the first alarm lower threshold. For example, when the first over-limit alarm condition is that the heart rate is greater than 120bpm, the second over-limit alarm condition may be that the heart rate value is in the range of 115bpm-120bpm.

The second alarm condition may also include a second abnormal event alarm condition. For example, when the second abnormal event alarm condition includes the waveform analysis condition corresponding to the abnormal event, for the same waveform, when analyzing it based on the first abnormal event alarm condition, the judgment result is that there is no abnormal event, and based on the second abnormal event When analyzing the waveform of the alarm condition, the judgment result may be that there is an abnormal event.

Exemplarily, the second alarm condition may be pre-set. When the controller 130 judges that the monitoring data of the target physiological parameter currently monitored does not meet the first alarm condition, it will invoke the pre-set second alarm condition to determine the current Whether the monitored monitoring data of the target physiological parameter meets the second alarm condition. Alternatively, the second alarm condition may be obtained by adjusting the first alarm condition. For example, when the controller 130 judges that the monitoring data of the target physiological parameter currently monitored does not meet the first alarm condition, the first alarm condition is adjusted. Adaptive adjustment to make it easier to meet, such as reducing the first alarm upper limit threshold or increasing the alarm lower limit threshold by a certain proportion, the adjusted first alarm condition constitutes the second alarm condition. Afterwards, the controller 130 judges whether the currently monitored monitoring data of the target physiological parameter satisfies the second alarm condition.

Referring to FIG. 3 , during the period from T2 to T3, the controller 130 judges that the currently monitored monitoring data of at least one target physiological parameter does not meet the first alarm condition, but meets the second alarm condition. Therefore, during this period, the control output device 120 Output the third alarm information. The stage of outputting the third alarm information is the alarm delay stage. The frequent occurrence of transient alarms can be reduced through the alarm delay. Although the alarm time is also increased, because the alarm delay in the embodiment of the present invention combines the user’s alarm reset operation, The third alarm information output in the alarm delay stage has a relatively unobtrusive presentation manner, so that alarm fatigue can be effectively avoided.

Wherein, the third alarm information may be the same as the second alarm information described above, specifically, the third alarm information may include a second alarm identifier, and the second alarm identifier includes a second alarm character string and is used to represent an alarm reset operation. The reset response flag, the second alarm string includes a string used to characterize at least one currently monitored physiological parameter monitoring data that meets the first overrun alarm condition, or includes a character string used to characterize at least one currently monitored physiological parameter The monitoring data of the parameter meets the string of the first abnormal event alarm condition. That is to say, although the monitoring data of the target physiological parameter does not meet the first alarm condition when the third alarm information is output, in order to maintain the continuity of the alarm, the third alarm information can still indicate that the monitoring data of the target physiological parameter meets the first alarm condition. condition.

Alternatively, the third alarm information may also be different from the second alarm information, but adopt other presentation manners that are not as prominent as the first alarm information. Exemplarily, the third alarm information includes a third alarm identifier displayed on the display, and the third alarm identifier includes a third alarm character string and a reset response mark for representing an alarm reset operation. Exemplarily, the third alarm character string may be different from the second alarm character string, for example, the third alarm character string includes characters used to indicate that the monitoring data of at least one physiological parameter currently monitored meets the second over-limit alarm condition Alternatively, the third alarm character string includes a character string used to indicate that the currently monitored monitoring data of at least one physiological parameter meets the second abnormal event alarm condition. That is to say, the third alarm information indicates that the target physiological parameter satisfies the second alarm condition, thereby avoiding the conflict between the third alarm mark and the monitoring data of the physiological parameter displayed on the monitoring interface. Or, the third alarm character string and the second alarm character string can be the same, but the third alarm character string and the second alarm character string can be displayed as different colors and/or different background colors, so as to distinguish the normal alarm stage from the alarm delay phase.

In the process of outputting the third alarm information, the controller 130 is also used to judge whether the monitoring data of at least one target physiological parameter currently monitored meets the first alarm condition again; When the monitoring data of physiological parameters meet the first alarm condition again, the controller 130 controls the output device 120 to re-output the second alarm information, so that the two alarm stages are connected through the alarm delay stage of outputting the third alarm information, and the number of alarms is reduced. , to avoid alarm fatigue. When the monitoring data of the target physiological parameter satisfies the first alarm condition again, the alarm information output by the output device 120 is the second alarm information, that is, the previous alarm reset operation is still valid, and the user does not need to reset the alarm again.

As shown in FIG. 3 , at time T4, the controller 130 judges that the monitoring data of the target physiological parameter satisfies the first alarm condition again, and T4<T3. Therefore, the output device 120 re-outputs the second alarm information during the period from T4 to T5. From the user's point of view, after the alarm is reset at time T1, the output device always outputs the alarm information in an unobtrusive manner, which can not only maintain the continuity of the alarm, but also reduce the interference to the user and avoid alarm fatigue. After the user resets the alarm at time T1, during the period from T4 to T5, the output device can still maintain the display mode of the alarm information after the alarm reset, without the need for the user to reset the alarm again, preventing the user from frequently resetting the alarm in a short period of time.

The controller 130 is also used to judge whether the time for outputting the third alarm information reaches the first time. When the time for outputting the third alarm information reaches the first time, if the monitoring data of at least one target physiological parameter still does not satisfy the first alarm condition, the controller 130 controls the output device to stop outputting the third alarm information. That is, the longest time for outputting the third alarm information is the first time. If the monitoring data of the target physiological parameter satisfies the first alarm condition again before then, the controller 130 controls the output device 120 to output the second alarm information again. If the monitoring data of the target physiological parameter does not satisfy the first alarm condition for a period of time, the controller 130 controls the output device to stop the alarm. After the output of the third alarm information is stopped, the alarm reset operation is correspondingly ineffective, and the controller 130 continues to judge whether the monitoring data of at least one target physiological parameter currently monitored meets the first alarm condition, and outputs an alarm when the first alarm condition is met. First alarm message.

In some embodiments, the controller 130 may also enable the alarm delay setting when the alarm reset operation is not obtained. Specifically, if the controller 130 does not obtain an alarm reset operation during the process of outputting the first alarm information, it may also determine that the currently monitored monitoring data of at least one target physiological parameter does not meet the first alarm condition. Whether the monitored monitoring data of at least one target physiological parameter meets the second alarm condition; when the controller 130 judges that the currently monitored monitoring data of at least one target physiological parameter does not meet the first alarm condition, but meets the second alarm condition , the control output device 120 outputs fourth alarm information. The stage of outputting the fourth alarm information is the alarm delay stage. Exemplarily, the first warning information has a more prominent presentation manner than the fourth warning information, for example, the fourth warning information may be the same as the second warning information or the third warning information. Alternatively, in order to maintain the continuity of the alarm information, the fourth alarm information may also be the same as the first alarm information.

In the process of outputting the fourth alarm information, the controller 130 judges whether the currently monitored monitoring data of at least one target physiological parameter satisfies the first alarm condition again. If it is judged that the currently monitored monitoring data of at least one target physiological parameter satisfies the first alarm condition again, the output device is controlled to output the first alarm information. When the time for outputting the fourth alarm information reaches the second time, if the currently monitored monitoring data of at least one target physiological parameter still does not satisfy the first alarm condition, the output device 120 is controlled to stop outputting the fourth alarm information. That is, the longest time for outputting the fourth alarm information is the second time. If the monitoring data of the target physiological parameter satisfies the first alarm condition again within the second time, the first alarm information will continue to be output, so that the two short-duration alarms Link to an alarm with a longer duration; if the monitoring data of the target physiological parameter does not meet the first alarm condition within the second time, the alarm is stopped.

Wherein, since the output of the fourth alarm information is not combined with the user's alarm reset operation, the second time for outputting the fourth alarm information is relatively short. Specifically, the length of the second time is shorter than the length of the first time. For example, the first time is 30s, and the second time is 3s-5s. The fourth alarm information can be used to connect two alarms with short time intervals, so as to prevent frequent alarms when the monitoring data of the target physiological parameter fluctuates under the first alarm condition.

Exemplarily, the controller 130 is further configured to control the display to display an alarm setting interface, and the alarm setting interface is used to set parameters related to alarm delay. Specifically, the setting operation of the second alarm condition may be received based on the alarm setting interface, and the second alarm condition may be set according to the setting operation, or the setting operation of the first time for outputting the third alarm information may be received based on the alarm setting interface, and the second alarm condition may be set according to the setting operation. Set the first time. The second alarm condition and/or the first time may also be fixed, or automatically set by the controller 130 according to certain rules. Exemplarily, the greater the difference between the second alarm condition and the first alarm condition, the lower the accuracy of the alarm, and therefore the shorter the length of the first time.

Several exemplary alarm processes of the patient monitoring device 100 in the embodiment of the present invention are shown below:

1. The patient's current heart rate value is 126bpm, and the first alarm condition is that the heart rate value is higher than 120bpm. The controller 130 judges that the patient's current heart rate value meets the first alarm condition, so it outputs the first alarm message indicating that the heart rate is too high;

During the process of outputting the first alarm information, the user's alarm reset operation is obtained;

After obtaining the user's alarm reset operation, the controller 130 controls the output device to change from the first alarm information to the second alarm information, such as stopping the sound and light alarm, and at the same time, adding "when the patient's current heart rate value does not meet the first alarm condition Use the second alarm condition" mark;

When the patient's heart rate value is not higher than 120bpm (for example, it drops to 118bpm), according to the mark of "use the second alarm condition when the patient's current heart rate value does not meet the first alarm condition", determine whether the heart rate value meets the second alarm condition : The heart rate value is between 115bpm-120bpm. The controller 130 judges that the heart rate value satisfies the second alarm condition, and then continues to output the third alarm information for 30s.

2. The patient's current heart rate value is 126 bpm, and the first alarm condition is that the heart rate value is higher than 120 bpm. The controller 130 judges that the patient's current heart rate value meets the first alarm condition, and therefore outputs the first alarm message indicating that the heart rate is too high;

During the process of outputting the first alarm information, the user's alarm reset operation is obtained;

After obtaining the user's alarm reset operation, the controller 130 controls the output device to change from the first alarm information to the second alarm information, such as stopping the sound and light alarm, and at the same time, adding "when the patient's current heart rate value does not meet the first alarm condition Use the second alarm condition" mark;

When the patient's heart rate value is not higher than 120bpm (for example, it drops to 118bpm), according to the mark of "use the second alarm condition when the patient's current heart rate value does not meet the first alarm condition", determine whether the heart rate value meets the second alarm condition : The heart rate value is between 115bpm-120bpm. The controller 130 judges that the heart rate value satisfies the second alarm condition, and then continues to output the third alarm information;

In the process of outputting the third alarm information, the controller 130 judges whether the patient's current heart rate value meets the first alarm condition; when the third alarm information continues to be output for 20 seconds, the patient's heart rate value rises to 125bpm, and the controller 130 judges whether the patient's heart rate value meets the first alarm condition. The current heart rate value satisfies the first alarm condition again, and the alarm reset operation is still valid, so the second alarm condition is output again.

3. The patient's current blood oxygen value is 88%, and the first alarm condition is that the blood oxygen value is lower than 90%. The controller 130 judges that the patient's current blood oxygen value satisfies the first alarm condition, so it outputs the first alarm condition indicating hypoxemia. - alarm information;

During the process of outputting the first alarm information, the user's alarm reset operation is obtained;

After obtaining the user's alarm reset operation, the controller 130 controls the output device to change from the first alarm information to the second alarm information, and at the same time, adds "when the patient's current blood oxygen value does not meet the first alarm condition, use the second alarm condition " mark;

When the blood oxygen value of the patient is not lower than 90% (for example, it rises to 91%), according to the mark of "using the second alarm condition when the patient's current blood oxygen value does not meet the first alarm condition", it is judged whether the blood oxygen value The second alarm condition is met: the blood oxygen value is between 90% and 92%. The controller 130 judges that the blood oxygen value satisfies the second alarm condition, and then continues to output the third alarm information for 30s.

4. The patient's current number of ventricular premature beats per minute (pvcs/min) is 12, the first alarm condition is that the number of ventricular premature beats is greater than or equal to 10, and the controller 130 judges that the patient's current number of ventricular premature beats meets The first alarm condition, therefore outputting the first alarm information indicating that the number of ventricular premature beats is too high;

During the process of outputting the first alarm information, the user's alarm reset operation is obtained;

After obtaining the user's alarm reset operation, the controller 130 controls the output device to change from the first alarm information to the second alarm information, and at the same time, add "when the patient's current pvcs/min does not meet the first alarm condition, use the second alarm condition " mark;

When the patient's pvcs/min is not higher than 10 (for example, it drops to 9), according to the mark of "the second alarm condition is adopted when the patient's current pvcs/min does not meet the first alarm condition", determine whether the pvcs/min The second alarm condition is met: pvcs/min is in [8,10). The controller 130 judges that the pvcs/min meets the second alarm condition, and then continues to output the third alarm information for 30s.

5. Collect the current invasive blood pressure (IBP) signal of the patient, and obtain the IBP pressure value (including systolic pressure, mean pressure or diastolic pressure, the systolic pressure is taken as an example below) according to the IBP signal. The first alarm condition is that the IBP systolic pressure is higher than 160mmHg, the controller 130 judges that the patient's current IBP systolic blood pressure meets the first alarm condition, and therefore outputs the first alarm information that is characterized as an excessively high IBP systolic blood pressure;

During the process of outputting the first alarm information, the user's alarm reset operation is obtained;

After obtaining the user's alarm reset operation, the controller 130 controls the output device to change from the first alarm information to the second alarm information, and at the same time, add "when the patient's current IBP systolic blood pressure does not meet the first alarm condition, use the second alarm Conditions" mark;

When the patient's IBP systolic blood pressure is not higher than 160mmHg, judge whether the IBP systolic blood pressure meets the second alarm condition according to the mark "when the patient's current IBP systolic blood pressure does not meet the first alarm condition, use the second alarm condition": IBP The systolic blood pressure is in the (155,160]mmHg interval. The controller 130 judges that the IBP systolic blood pressure meets the second alarm condition, and then continues to output the third alarm information for 30s. In the process of continuing to output the third alarm information for 30s, the previous second alarm can be continued Information can also be presented in different ways, such as changing the background color of the alarm sign displayed on the display.

To sum up, the patient monitoring device 100 of the embodiment of the present invention performs alarm delay in combination with the user's alarm reset operation, so that the third alarm information output during the alarm delay stage has a relatively unobtrusive presentation mode, thus effectively avoiding alarm fatigue.

Next, an alarm method for a patient monitoring device according to an embodiment of the present invention will be described with reference to FIG. 6 . FIG. 6 is a schematic flowchart of an alarm method 600 for a patient monitoring device according to an embodiment of the present invention.

As shown in FIG. 6, the alarm method 600 of the patient monitoring device according to the embodiment of the present invention includes the following steps:

In step S610, obtain the monitoring data of at least one physiological parameter of the patient, and display the monitoring data of the physiological parameter in the monitoring interface;

In step S620, it is judged whether the currently monitored monitoring data of at least one target physiological parameter satisfies the first alarm condition;

In step S630, when it is judged that the currently monitored monitoring data of at least one target physiological parameter satisfies the first alarm condition, output first alarm information;

In step S640, during the process of outputting the first alarm information, the user's alarm reset operation is acquired;

In step S660, outputting second alarm information in response to the alarm reset operation, wherein the first alarm information has a more prominent presentation manner than the second alarm information;

In step S660, in the process of outputting the second alarm information, it is determined whether the monitoring data of the at least one physiological parameter currently monitored meets the first alarm condition, and whether the monitoring data of the at least one physiological parameter currently monitored is Whether the monitoring data of the parameter meets the second alarm condition;

In step S670, if it is judged that the monitoring data of the at least one target physiological parameter currently monitored does not meet the first alarm condition but meets the second alarm condition, output third alarm information, wherein the The second alarm condition is easier to meet than the first alarm condition, and the first alarm information has a more prominent presentation manner than the third alarm information.

Further, the method further includes: in the process of outputting the third alarm information, judging whether the currently monitored monitoring data of at least one target physiological parameter meets the first alarm condition again; When the monitoring data of the target physiological parameter meets the first alarm condition again, the second alarm information is output. Conversely, when the time for outputting the third alarm information reaches the first time, if the monitoring data of at least one target physiological parameter still does not satisfy the first alarm condition, then stop outputting the third alarm information.

Exemplarily, the first alarm information includes a first alarm identifier displayed on the display; the second alarm information includes a second alarm identifier displayed on the display. The first alarm identifier includes a first alarm character string, and the second alarm identifier includes a second alarm character string and a reset response mark for representing an alarm reset operation.

Exemplarily, the first alarm condition includes a first over-limit alarm condition, the second alarm condition includes a second over-limit alarm condition, and the first alarm character string and the second alarm character string include at least The monitoring data of a physiological parameter meets the character string of the first overrun alarm condition. Alternatively, the first alarm condition includes a first abnormal event alarm condition, the second alarm condition includes a second abnormal event alarm condition, and the first alarm character string and the second alarm character string include at least one physiological parameter used to characterize the currently monitored The string of monitoring data that meets the alarm condition of the first abnormal event. The first alarm character string is the same as or different from the second alarm character string.

The stage of outputting the third alarm information is an alarm delay stage, and the third alarm information has a less prominent presentation manner than the first alarm information. The third alarm information is the same as the second alarm information, or the third alarm information is different from the second alarm information.

The alarm method 600 for the patient monitoring device of this embodiment can be implemented in the patient monitoring device 100 described above, specifically, each step of the alarm method 600 for the patient monitoring device can be executed by the controller 130 of the patient monitoring device 100 . For specific details of the alarm method of the patient monitoring device, reference may be made to the relevant description of the patient monitoring device 100 above, and details are not repeated here. The alarm method 600 of the patient monitoring device according to the embodiment of the present invention combines the user's alarm reset operation to delay the alarm, so that the third alarm information output during the alarm delay stage has a relatively unobtrusive presentation mode, thus effectively avoiding alarm fatigue.

An embodiment of the present invention also provides a patient monitoring device. Referring again to FIG. 1 , the patient monitoring device includes a data acquisition module 110 , an output device 120 and a controller 130 . The controller 110 is used to obtain the monitoring data of at least one physiological parameter of the patient; the output device 120 includes at least a display, and the display is used to display the monitoring data of the physiological parameter in the monitoring interface; the controller 130 is used to perform the following steps: determine the current monitoring Whether the monitored monitoring data of at least one target physiological parameter meets the first alarm condition; when it is judged that the currently monitored monitoring data of at least one target physiological parameter meets the first alarm condition, the control output device 120 outputs the first alarm information; In the process of outputting the first alarm information, the user's alarm reset operation is obtained; in response to the alarm reset operation, the output device 120 is controlled to output the second alarm information, wherein the first alarm information has a more prominent feature than the second alarm information. Presentation mode: in the process of outputting the second alarm information, if it is judged that the monitoring data of at least one physiological parameter currently monitored does not meet the first alarm condition, the output device 120 is controlled to output the third alarm information, and the first alarm information corresponds to Compared with the third alarm information, it has a more prominent presentation mode; in the process of outputting the third alarm information, it is judged whether the monitoring data of at least one target physiological parameter currently monitored meets the first alarm condition again; if the current monitoring If the received monitoring data of at least one target physiological parameter satisfies the first alarm condition again, the output device 120 is controlled to output the second alarm information.

Further, the controller 130 is further configured to: when the time for outputting the third alarm information reaches the third time, if the monitoring data of the target physiological parameter still does not satisfy the first alarm condition, control the output device 120 to stop outputting the alarm information .

The patient monitoring device in this embodiment also triggers the alarm delay in combination with the user’s alarm reset operation. What is different from the aforementioned patient monitoring device is that after the user’s alarm reset operation is obtained, if the controller 130 judges that the monitoring data of the target physiological parameter does not meet the During the first alarm condition, it does not judge whether the monitoring data of the target physiological parameter meets the second alarm condition, but directly triggers the alarm delay, that is, continues to output the third alarm information. If the monitoring data of the target physiological parameter satisfies the first alarm condition again before the output of the third alarm information reaches the third time, the controller 130 controls the output device 120 to continue to output the second alarm information, thereby realizing the two alarms through alarm delay. Connection, no need for the user to reset the alarm again. If the monitoring data of the target physiological parameter always meets the first alarm condition within the third time period, the controller 130 controls the output device 120 to stop the alarm. For other specific details about the patient monitoring device, reference may be made to the relevant description above, which will not be repeated here.

Correspondingly, an embodiment of the present invention also provides an alarm method for a patient monitoring device. Referring to FIG. 7 , the alarm method 700 for a patient monitoring device includes the following steps:

In step S710, the monitoring data of at least one physiological parameter of the patient is obtained, and the monitoring data of the physiological parameter is displayed on the monitoring interface;

In step S720, it is judged whether the currently monitored monitoring data of at least one target physiological parameter satisfies the first alarm condition;

In step S730, when it is judged that the currently monitored monitoring data of at least one target physiological parameter satisfies the first alarm condition, output first alarm information;

In step S740, during the process of outputting the first alarm information, the user's alarm reset operation is acquired;

In step S750, outputting second alarm information in response to the alarm reset operation, wherein the first alarm information has a more prominent presentation manner than the second alarm information;

In step S790, if it is judged that the currently monitored monitoring data of at least one target physiological parameter satisfies the first alarm condition again, the second alarm information is output.

The alarm method 700 for the patient monitoring device of this embodiment can be implemented in the patient monitoring device 100 described above, specifically, each step of the alarm method 700 for the patient monitoring device can be executed by the controller 130 of the patient monitoring device 100 . For specific details of the alarm method of the patient monitoring device, reference may be made to the relevant description of the patient monitoring device 100 above, and details are not repeated here. The alarm method 700 of the patient monitoring device in the embodiment of the present invention combines the user's alarm reset operation to delay the alarm, so that the third alarm information output during the alarm delay stage has a relatively unobtrusive presentation mode, so that alarm fatigue can be effectively avoided; and through In the alarm delay stage, the two alarm stages will be connected to prevent users from frequently performing alarm reset operations.
