Description

A soft chest compression device

technical field

The invention belongs to the technical field of medical devices, and in particular relates to a soft chest compression device.

Background technique

Once cardiac arrest occurs, if the patient is not rescued and resuscitated in time, it will cause irreversible damage to the brain and other vital organs and tissues in 4 to 6 minutes. Therefore, cardiopulmonary resuscitation after cardiac arrest must be performed immediately at the scene. , to win the most precious time for further rescue until the life of the patient suffering from cardiac arrest, the so-called "Golden Four Minutes". In terms of rescue equipment, the existing rescue equipment generally adopts a rigid structure, and the equipment is bulky and difficult to carry.

Cardiopulmonary resuscitation refers to the continuous and rhythmic pressing of the sternum, which increases the intrathoracic pressure, indirectly compresses the left and right ventricles, allows blood to flow into the aorta, establishes circulation, and creates conditions for the recovery of the heart's autonomic rhythm. There are two common methods of CPR: manual CPR or CPR using a CPR machine. Artificial cardiopulmonary resuscitation is a procedure in which the rescuer performs chest compressions on the patient with bare hands, and at the same time assists the breathing to establish a temporary artificial circulation for the patient's breathing cycle, which is conducive to the recovery of the patient's cardiac function.

Manual cardiopulmonary resuscitation is a double test of the rescuer's skills and endurance. Studies have shown that due to physical exhaustion, the quality of the operator's compression begins to decline 1 to 2 minutes after the start of the compression. not ideal. Secondly, limited by the rescuer's proficiency in CPR first aid skills, during the operation, the depth of each compression cannot be guaranteed to be consistent, resulting in different depths and affecting the compression effect.

The CPR machine can perform continuous chest compressions with the same frequency and amplitude through the set parameters. However, most cardiac arrests occur outside the hospital, and CPR equipment is often too cumbersome to carry, unable to reach the phenomenon in the first time for rescue, delaying the timing of treatment.

In the prior art, patent application CN201410369578.4 discloses a cardiopulmonary resuscitation machine, which is used to perform continuous chest compression on a patient.

Although the cardiopulmonary resuscitation machines disclosed in the above two patent applications can improve continuous chest compressions in terms of functions, they are still lacking in portability and comfort due to the constraints of their mechanical structures.

As shown in FIG. 1 and FIG. 2 , an embodiment of the present invention provides a soft chest compression device, which is easy to carry outdoors. When encountering a patient with cardiac arrest outdoors, the soft chest compression device can be used. Timely cardiopulmonary resuscitation is performed on the patient, so as to win precious time for the doctor's rescue. Specifically, the software chest compression device includes an adaptive tightening belt 10, a compression unit 20, a fluid pump 30 and a controller 40, which constitute the core structure of the software chest compression device. The self-adaptive tightening belt 10 is provided with an installation position 11 , and the self-adaptive tightening belt 10 forms a binding space 12 , and the pressing unit 20 includes a fixed seat 21 and a telescopic pressing head 22 . In the process of using the soft chest compression device, the patient's chest needs to be appropriately located in the binding space 12, and the adaptive tightening belt 10 is used to bind the patient's chest position to stabilize the compression unit 20 and facilitate the compression. In addition, the telescopic pressing head 22 is made of flexible soft material, and the telescopic pressing head 22 can press against the patient's chest relatively softly, thereby effectively protecting the patient. When assembling the soft chest compression device, the fixed seat 21 of the compression unit 20 is connected to the installation position 11 of the adaptive tightening belt 10, and one end of the telescopic compression head 22 is connected to the fixed seat 21. When one end extends and presses the patient's chest, the other end is located in the binding space 12. When the other end of the telescopic pressing head 22 is retracted, the other end is accommodated in the fixing seat 21 (at this time, the The other end can be completely accommodated in the fixing seat 21, or the other end of the telescopic pressing head 22 can be retracted to be flush with the inner surface of the adaptive tightening belt 10), and the adaptive tightening belt 10 can be put on the patient. When the telescopic pressing head 22 is accommodated in the fixing seat 21, the telescopic pressing head 22 will not bear against the patient's chest and cause discomfort to the patient's chest. The telescopic pressing head 22 is provided with a fluid exchange port 23, and the fluid pump 30 communicates with the fluid exchange port 23 (when the fluid adopts liquid fluid, then the fluid pump 30 communicates with the fluid exchange port 23 through the connecting pipe; when the fluid adopts gaseous fluid , the fluid pump 30 can be connected to the fluid exchange port 23 through the connecting pipe, or the delivery port of the fluid pump 30 can be directly connected to the fluid exchange port 23. At this time, the fluid pump 30 is connected and fixed on the adaptive tightening belt 10 ). The controller 40 is electrically connected to the fluid pump 30 . During the working process of the soft chest compression device, intelligent automatic control is realized by the controller 40, that is, after the self-adaptive tightening belt 10 is bound to the patient, the controller 40 controls the fluid pump 30 to work to exchange the fluid from the fluid. The port 23 is filled into the retractable compression head 22 or the fluid is extracted from the retractable compression head 22 (when the fluid is poured, the retractable compression head 22 is slowly stretched out to reach the chest of the patient; Extracted from the telescopic pressing head 22, the telescopic pressing head 22 contracts to release the patient's chest), thus driving the telescopic pressing head 22 to achieve a continuous and balanced pressing operation on the patient's chest.

Compared with the existing chest compression equipment, the design structure of the software chest compression device of the present invention is simplified, and the modular design method is adopted, and the simplified software chest compression device is relatively light and easy to carry when going out. In the event of a patient suffering from cardiac arrest, the software chest compression device of the present application can be used to perform cardiopulmonary resuscitation on the patient in a timely manner.

The first end of the linear telescopic structure 221 is connected to the fixed seat 21 to stabilize the telescopic pressing head 22 as a whole. The fixed seat 21 acts as a force supporting point during the pressing process, and the pressure sensor 222 is connected to the first end of the linear telescopic structure 221 , and the pressure sensor 222 is located between the first end of the linear telescopic structure 221 and the fixed seat 21, and the pressure sensor 222 is electrically connected to the controller 40. During the continuous compression of the patient's chest, the pressure sensor 222 detects the compression pressure in real time, and The controller 40 calculates and analyzes the compression pressure in real time. When the compression pressure is detected and analyzed, the controller 40 controls the flow rate and flow rate of the fluid delivered by the fluid pump 30 to change, thereby correcting the compression pressure on the patient's chest. In addition, the displacement sensor 223 is connected to the second end of the linear telescopic structure 221, and the displacement sensor 223 is electrically connected to the controller 40. When the pressure sensor 222 is used to detect the pressing pressure in real time, the second end of the telescopic pressing head 22 is also detected at the same time. The distance traveled back and forth during the pressing process is detected and fed back to the controller 40, and the controller 40 performs calculation and analysis, and then the controller 40 combines the pressing displacement data of the second end of the telescopic pressing head 22 with the pressing pressure data, so as to precisely control the telescopic the pressing pressure of the pressing head 22.
