Description

Technical Field

[0001] The present invention relates to a cardiopulmonary resuscitation training feedback device, specifically a portable cardiopulmonary resuscitation feedback device, belonging to the technical field of medical education and training. Background Art

[0002] Cardiopulmonary resuscitation (CPR) is an emergency rescue measure for patients with cardiac and respiratory arrest, aiming to maintain the patient's blood circulation and respiratory function through artificial means until professional medical personnel arrive or the patient resumes spontaneous heartbeat and breathing. Chest compressions are a key component of cardiopulmonary resuscitation, aiming to push blood flow by pressing on the patient's chest and maintain oxygen supply to vital organs. High-quality cardiopulmonary resuscitation has specific requirements for the depth and frequency of chest compressions. When rescuing a patient, medical staff usually carry out the rescue according to the usual training mode, and there is currently no data recording and feedback on whether the established depth and frequency are achieved.

[0003] Traditional cardiopulmonary resuscitation training mainly relies on the induction device integrated in the model for feedback, so that medical staff can make relevant adjustments according to the data. However, most of the induction devices are integrated inside the model and do not have a disassembly function. There are not only problems of difficult replacement and high use cost, but also the feedback device for daily training cannot be directly applied to actual cardiopulmonary resuscitation rescue. As a result, medical staff can only rely on daily training experience for relevant operations, unable to control the quality of cardiopulmonary resuscitation operations, which is likely to affect the success rate of rescue. Moreover, during the rescue process, due to insufficient force control, it is easy to cause chest fractures in patients. Therefore, a portable cardiopulmonary resuscitation feedback device is proposed. Summary of the Invention

One end of the second spring 605 is fixedly connected to one side of the inner side wall of the syringe 602, and the other end of the second spring 605 is fixedly connected to one side of the carriage 603.

[0031] The syringe 602 is connected to the one-way valve 601 by moving it in a threaded manner. Then, the carriage 603 is driven to move by moving the push rod 606. The moving carriage 603 drives the gasket 604 to cooperate with the one-way valve 601 to inject the air in the syringe 602 into the airbag wristband 501. At the same time, the moving carriage 603 drives the second spring 605 to be stretched. The provided vibrator 503 is used to give a vibration prompt to the wrist of the medical staff; after the daily training is completed, the wrist monitoring mechanism 5 can be sleeved on the wrist of the mannequin 101, specifically as Figure 1 shown.

[0032] In one embodiment, both locking mechanisms 7 each include three locking holes 701, three locking blocks 702, a guide pressing plate 703, three third springs 704, a sliding plate 705, a connecting plate 706, a stepped sliding groove 707, and a guide groove 708; Among them, the three locking holes 701 are all opened on one side of the machine box 201. The outer side walls of the three locking blocks 702 are respectively slidably connected to the inner side walls of the three locking holes 701. The guide pressure plate 703 is fixedly connected to one end of the three locking blocks 702 away from the locking holes 701. The outer side wall of the guide pressure plate 703 is slidably connected to the inner side wall of the mounting base 102. One ends of the three third springs 704 are all fixedly connected to one side of the guide pressure plate 703, and the other ends of the three third springs 704 are all fixedly connected to the inner side wall of the mounting base 102. One end of the connecting plate 706 is fixedly connected to the middle of one side of the guide pressure plate 703. The outer side wall of the connecting plate 706 is slidably connected to the inner side wall of the mounting base 102. The guide groove 708 is opened on one side of the mounting base 102. The outer side wall of the sliding plate 705 is slidably connected to the inner side wall of the guide groove 708. One end of the connecting plate 706 away from the guide pressure plate 703 penetrates through the mounting base 102 and extends into the sliding plate 705. The stepped chute 707 is opened in the middle of the inner side wall of the sliding plate 705. The inner side wall of the stepped chute 707 is slidably connected to the outer side wall of the connecting plate 706.

[0033] By pushing the sliding plate 705 to slide in the guide groove 708, the stepped chute 707 in the sliding plate 705 is used to drive the connecting plate 706 to move. The moving connecting plate 706 drives the guide pressure plate 703 to move. The moving guide pressure plate 703 drives the locking block 702 to slide out of the locking hole 701 and drives the third spring 704 to be compressed, so as to release the limit on the machine box 201.

[0034] When the present invention is working: when cardiopulmonary resuscitation training is required, the elastic band 401 is stretched by moving the machine shell 402, so that both hands can be placed between the machine shell 402 and the flexible pressing pad 202. Then, by pressing the flexible pressing pad 202, the bearing plate 203 is driven to move. The moving bearing plate 203 drives the support block 204 and the accelerometer 302 to move. The moving accelerometer 302 detects the acceleration data of the bearing plate 203 and feeds back the detection result to the central control module 301. The moving support block 204 drives the first spring 206 to move. The moving first spring 206 squeezes the sleeve 205 to be compressed, so as to buffer the pressure. Then, the pressure is transmitted to the machine box 201 through the cooperation of the sleeve 205 and the support plate 207, so that the machine box 201 drives the flexible pressure sensor 303 and the sponge pad 81 to squeeze the bottom of the mounting base 102. Then, the force can be transmitted to the chest of the human body model 101 through the mounting base 102. The sponge pad 81 provided is compressed and deformed under the action of the pressure. The flexible pressure sensor 303 provided is used to detect the pressure data between the machine box 201 and the mounting base 102 and feeds back the detection result to the central control module 301.

[0035] After the chest compression action is completed, the support block 204 is pushed to move in the reverse direction by the compressed first spring 206. The moving support block 204 pushes the bearing plate 203 to drive the support block 204 and the accelerometer 302 to reset, so as to perform cyclic compression operations. The set counter 305 is used to increment the count by one after a complete chest compression and reset, and the ventilation ratio of the dismountable auxiliary mechanism 2 is controlled by counting.

[0036] The set central control module 301 is used to receive the feedback from the accelerometer 302, the flexible pressure sensor 303 and the counter 305, and transmit the feedback data to the display screen 403 for display. When the data detected by the accelerometer 302 and the flexible pressure sensor 303 exceeds the threshold, the central control module 301 starts the warning light 404 to work, so as to remind the medical staff to correct the cardiopulmonary resuscitation training actions by means of lighting.

[0037] When it is necessary to remove the dismountable auxiliary mechanism 2 from the inside of the mounting base 102, the slide plate 705 is pushed to slide in the guide groove 708. The stepped chute 707 in the slide plate 705 drives the connecting plate 706 to move. The moving connecting plate 706 drives the guide pressure plate 703 to move. The moving guide pressure plate 703 drives the locking block 702 to slide out of the locking hole 701 and drives the third spring 704 to be compressed, so as to release the limit on the machine box 201. After the machine box 201 is taken out of the mounting base 102, the slide plate 705 is moved in the reverse direction to reset, and then the compressed third spring 704 is used to push the guide pressure plate 703 to drive the locking block 702 to reset.

[0038] When actually performing cardiopulmonary resuscitation first aid, the machine box 201 is moved to drive the sponge pad 81 to fit on the specified position of the patient's chest. Then the airbag wristband 501 is moved and the elastic band 502 is used to wear the vibrator 503 on the wrist of the medical staff. Then the above operations are repeated. The dismountable auxiliary mechanism 2 is used in cooperation with the feedback detection mechanism 3 to perform cardiopulmonary resuscitation operations, and the relevant data is checked and displayed. When the data detected by the accelerometer 302 and the flexible pressure sensor 303 exceeds the threshold, the central control module 301 starts the warning light 404 and the vibrator 503 to work. The working warning light 404 gives a lighting prompt to the medical staff, and the working vibrator 503 vibrates, so as to give a wrist vibration prompt to the medical staff.

[0039] The provided air injection mechanism 6 is used to control the expansion amplitude of the airbag wristband 501 so as to adapt to the wearing of different people. When it is necessary to adjust the expansion amplitude of the airbag wristband 501, the air cylinder 602 is moved to be connected to the one-way valve 601 in a threaded manner. Then, the carriage 603 is driven to move by moving the pressure lever 606. The moving carriage 603 drives the sealing gasket 604 to cooperate with the one-way valve 601 to inject the air in the air cylinder 602 into the airbag wristband 501. At the same time, the second spring 605 is stretched by the moving carriage 603. When it is necessary to reset the pressure lever 606, the carriage 603 is driven to move in the reverse direction by the stretched second spring 605. The sealing gasket 604 is deformed by the negative pressure in the air cylinder 602 so as to fill the space between the sealing gasket 604 and the air cylinder 602 with external air, enabling the air injection mechanism 6 to repeatedly inject air into the airbag wristband 501. After the air injection is completed, the entire air cylinder 602 can be removed from one end of the one-way valve 601 by using the thread. The provided exhaust valve 504 is used to discharge the air in the airbag wristband 501 so as to cause the expanded airbag wristband 501 to contract to adapt to different people.

[0040] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various changes or substitutions, and these should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
