Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a flowchart of an automatic zero calibration method of a weighing type infusion alarm provided by the embodiment of the application, and specifically includes the following steps:
s101: and determining the running state of the infusion alarm according to the weight measured by the infusion alarm.
In the embodiment of the application, the server can determine the operation state of the infusion alarm according to the weight measured by the infusion alarm, and divides the different operation states of the infusion alarm so as to automatically correct zero according to the different states of the infusion alarm.
Specifically, the server can divide the operation state of the infusion alarm into a working state, an idle state and a stable state.
The idle state represents a state that the infusion alarm is not hung with a heavy object, and the weight measured by the infusion alarm is 0 and is basically kept unchanged.
The server can count the weight measured by the infusion alarm, and if the numerical value of the weight measured by the infusion alarm in a preset time period does not float beyond a preset range taking 0 as a center, namely, the numerical values of the weight measured by the infusion alarm in the preset range are all 0 or close to 0, the infusion alarm can be determined to be in an idle state. The data size included in the preset range is generally small, and the values of the preset range and the preset time period can be set according to needs, which is not limited in the present application.
The steady state indicates a state in which the weight measured by the infusion alarm remains substantially unchanged.
The server can count the weight measured by the infusion alarm, and if the numerical value of the weight measured by the infusion alarm in a preset time period does not float beyond a preset range, namely the numerical value of the weight measured by the infusion alarm is stabilized near a certain fixed value and basically remains unchanged, the infusion alarm can be determined to be in a stable state. The preset range corresponding to the idle state of the infusion alarm and the preset range corresponding to the stable state comprise the same or different data volume, and the data volume can be specifically set according to needs, and the application does not limit the data volume.
It should be noted that the range of the steady state is substantially larger than the range of the idle state, and the range of the idle state is included, but in the embodiment of the present application, the idle state is distinguished from the steady state, and the steady state is defined as a state in which the weight measured by the infusion alarm in a preset time period is not 0 and is substantially kept unchanged.
The working state represents the state that an infusion bag, an infusion bottle and the like are hung on the infusion alarm and a patient is in the infusion process.
The server can regard other operation time of the infusion alarm outside the two states as a working state according to the determined idle state and stable state of the infusion alarm. Alternatively, the server may count the weight measured by the infusion alarm, and determine that the infusion alarm is in the working state if the value of the weight measured by the infusion alarm in a preset time period steadily decreases according to a certain trend, that is, the rate of decrease of the value of the weight measured by the infusion alarm is substantially constant.
S102: and acquiring zero data corresponding to the infusion alarm in an idle state.
In the embodiment of the application, the server can acquire zero data corresponding to the infusion alarm when the infusion alarm is determined to be in an idle state, so that the infusion alarm can be automatically calibrated according to the zero data.
In one embodiment, since the weight measured by the infusion alarm may slightly change within a preset range, the server may collect zero-point data corresponding to the infusion alarm in the idle state for a plurality of times according to a preset time interval in order to determine the zero-point data corresponding to the infusion alarm in the idle state. The server may average the zero-point data acquired according to the number of times of acquiring the zero-point data, and use the average as the zero-point data of the infusion alarm.
In one embodiment, the server may store the determined zero-point data of the infusion alarm after determining the zero-point data of the infusion alarm, so as to automatically zero the infusion alarm according to the stored zero-point data.
S103: and when the transfusion alarm is determined to be in a stable state, automatically calibrating the transfusion alarm according to the zero data.
In the embodiment of the application, when the server can determine that the infusion alarm is in a stable state, the server automatically corrects zero of the infusion alarm according to the pre-stored zero data of the infusion alarm.
Specifically, in the actual use process, when the infusion alarm is in an idle state, the infusion alarm can be confirmed to be in an empty hook state without hanging a heavy object. If the infusion alarm is continuously used for multiple times, the weighing sensor in the infusion alarm is always switched back and forth between the load-bearing state and the idle hook state, which may have adverse effects on the zero data of the infusion alarm in the idle state and influence the accuracy of the zero data of the infusion alarm in the idle state.
Therefore, before the server automatically corrects zero of the infusion alarm in the stable state, the server can determine the duration corresponding to the latest idle state of the infusion alarm before the stable state, and automatically corrects zero of the infusion alarm according to the duration corresponding to the latest idle state and corresponding zero data.
If the duration time of the last idle state is not less than the preset threshold value, the last recent idle hook state of the infusion alarm continues for a long time, and the server can automatically zero the infusion alarm according to the zero data of the recent idle state.
If the duration of the last idle state is less than the preset threshold value, which indicates that the last recent idle state of the infusion alarm lasts for a short time, the infusion alarm may have the above-mentioned zero data affected. Therefore, the server can determine the last idle states of the infusion alarm, respectively determine the zero data of the idle states of the times, and synthesize the zero data to automatically zero the infusion alarm. The preset threshold of the duration should be greater than the preset time period, and the specific value may be set as required, which is not limited in the present application.
The server can specifically adopt the methods of averaging, taking a median, removing the maximum and minimum values and the like to automatically zero the infusion alarm according to a plurality of zero data. The number of the zero point data can be set as required, and the zero point data is not limited in the application.
The zero drift phenomenon of the infusion alarm, namely the weight measured by a weighing sensor in the infusion alarm and the numerical value of the weight displayed by the weighing sensor deviate from the standard numerical value.
Therefore, when the server automatically corrects the infusion alarm, the server can correct the weight measured by the weighing sensor of the infusion alarm and the corresponding relation between the measured weight and the displayed numerical value according to the pre-stored zero data, so that the infusion alarm has the correct zero point.
In the embodiment of the application, the server can divide the working states of the infusion alarm according to a certain judgment standard. And then, the server can collect zero data corresponding to the idle state of the infusion alarm, and automatically zero the infusion alarm when the infusion alarm is determined to be in a stable state.
By the method, the infusion alarm can be automatically calibrated to zero according to the zero data of the infusion alarm in the idle state based on the division of the working state of the infusion alarm. Therefore, the complex manual zero calibration operation is saved, the maintenance cost is reduced, the measurement precision of the infusion alarm is improved, and the safety of the patient in the infusion process is guaranteed.
Furthermore, in the embodiments of the present application, the steady state of the infusion alarm can be divided into three cases: the first situation is that the infusion alarm is actually in an empty hook state, but due to the zero drift phenomenon, the display data of the infusion alarm is not 0 but is on a numerical value with a deviation from 0; the second condition is that the transfusion alarm is hung with empty or full transfusion bag, transfusion bottle and other appliances, but the patient does not perform transfusion; in the third situation, other accidental articles, such as clothes of a patient, woven bags and the like, are hung on the infusion alarm.
Therefore, the server can distinguish the situations according to the corresponding numerical value of the infusion alarm in the stable state.
Specifically, the server may determine, according to a preset value, that the value corresponding to the steady state is not greater than the preset value, corresponding to the first condition; determining that the value corresponding to the stable state is the same as the preset weight of the infusion apparatus, and corresponding to the second condition; and when other values corresponding to the stable state are determined to be larger than the preset value except the values corresponding to the second condition, corresponding to the third condition.
Therefore, the server can send out an alarm signal to remind the patient when the transfusion alarm is determined to be in the third condition, and the influence on the measurement precision of the transfusion alarm caused by the fact that the patient uses the transfusion alarm for a long time to hang other articles is prevented.
Based on the same inventive concept, the above automatic zero calibration method for the weighing type infusion alarm provided by the embodiment of the present application further provides a corresponding automatic zero calibration device for the weighing type infusion alarm, as shown in fig. 2.
Fig. 2 is a schematic structural view of an automatic zero calibration device of a weighing type infusion alarm provided by the embodiment of the application, and the automatic zero calibration device specifically comprises:
the determining module 201 is used for determining the operation state of the infusion alarm according to the weight measured by the infusion alarm; the running state comprises an idle state, a stable state and a working state;

and the zero calibration module 203 is used for automatically calibrating the infusion alarm according to the zero data when the infusion alarm is determined to be in a stable state.
