Description

Technical Field

[0001] This utility model relates to a cardiopulmonary resuscitation (CPR) training feedback device, specifically a portable CPR feedback device, belonging to the field of medical education and training technology. Background Technology

[0002] Cardiopulmonary resuscitation (CPR) is an emergency rescue measure for patients experiencing cardiac and respiratory arrest. It aims to maintain the patient's blood circulation and respiratory function artificially until professional medical personnel arrive or the patient regains spontaneous heartbeat and breathing. Chest compressions are a crucial component of CPR; their purpose is to propel blood flow and maintain oxygen supply to vital organs by pressing on the patient's chest. High-quality CPR has specific requirements for chest compression depth and frequency. Currently, medical personnel typically perform resuscitation according to their training routines, and there is no data or feedback on whether the predetermined depth and frequency are achieved.

[0003] Traditional cardiopulmonary resuscitation (CPR) training relies primarily on integrated sensors within the model for feedback, allowing medical personnel to make adjustments based on the data. However, these sensors are often integrated within the model and lack disassembly capabilities, leading to difficulties in replacement and high operating costs. Furthermore, the feedback devices learned during daily training cannot be directly applied to actual CPR resuscitation, forcing medical personnel to rely solely on their training experience. This lack of control over the quality of CPR procedures can negatively impact the success rate of resuscitation. Additionally, insufficient force control during resuscitation can easily result in thoracic fractures in patients. Therefore, a portable CPR feedback device is proposed. Utility Model Content

[0045] like Figures 1-10 As shown, this utility model embodiment provides a portable cardiopulmonary resuscitation feedback device, including a model component 1 and a detachable auxiliary mechanism 2. The model component 1 includes a human model 101, a mounting base 102 and a cavity 103.

[0046] The mounting base 102 is fixedly connected to the chest of the human body model 101. The cavity 103 is opened in the middle of the inner wall of the human body model 101.

The inner side of the mounting base 102 is equipped with two locking mechanisms 7.

[0047] The detachable auxiliary mechanism 2 is used to cooperate with the mounting base 102 to transmit force to the chest of the human body model 101, and can be detached from the mounting base 102 for separate use;

[0048] Among them, the feedback detection mechanism 3 is used in conjunction with the disassembly-type auxiliary mechanism 2 to detect the pressure, frequency and number of times, and supports Bluetooth data transmission;

[0049] The display mechanism 4 is used to display the data detected by the feedback detection mechanism 3 and to provide light prompts.

[0050] Among them, the wrist monitoring mechanism 5 is used to cooperate with the data detected by the feedback detection mechanism 3 to provide wrist vibration prompts;

[0051] The locking mechanism 7 is used to lock the mounting base 102 and the detachable auxiliary mechanism 2, and after locking, the detachable auxiliary mechanism 2 can still slide up and down within the mounting base 102.

[0052] In one embodiment, the detachable auxiliary mechanism 2 includes a housing 201, a flexible pressing pad 202, a pressure plate 203, two support blocks 204, two sleeves 205, two first springs 206, and a support plate 207.

[0053] The outer wall of the housing 201 is slidably connected to the inner wall of the human body model 101. The flexible pressing pad 202 is fixedly connected to the upper surface of the housing 201. The pressure plate 203 is located at the bottom of the flexible pressing pad 202. One end of each of the two support blocks 204 is fixedly connected to the bottom of the pressure plate 203. The support plate 207 is fixedly connected to the bottom of the inner wall of the housing 201. The two sleeves 205 are fixedly connected to the upper surface of the support plate 207. The ends of the two support blocks 204 away from the pressure plate 203 are slidably connected to the inner walls of the two sleeves 205. One end of each of the two first springs 206 is fixedly connected to the bottom of the inner walls of the two sleeves 205. The other ends of the two sleeves 205 are fixedly connected to the bottom of the two support blocks 204. A sponge pad 81 is fixedly connected to the bottom of the housing 201.

[0054] By pressing the flexible pressing pad 202, the pressure plate 203 is moved. The moving pressure plate 203 moves the support block 204. The moving support block 204 moves the first spring 206. The moving first spring 206 compresses the sleeve 205 to buffer the pressure. Then, the sleeve 205, in conjunction with the support plate 207, transmits the pressure to the housing 201. The housing 201 then uses the sponge pad 81 to press the bottom of the mounting base 102, and the force is transmitted to the chest of the human model 101 through the mounting base 102.

[0055] In one embodiment, the feedback detection mechanism 3 includes a central control module 301, an accelerometer 302, a flexible pressure sensor 303, a Bluetooth module 304, and a counter 305;

[0056] The central control module 301 is installed in the middle of the upper surface of the support plate 207, the accelerometer 302 is installed in the middle of the lower surface of the pressure plate 203, the flexible pressure sensor 303 is installed at the bottom of the housing 201, the Bluetooth module 304 is installed on one side of the central control module 301, and the counter 305 is installed on the other side of the central control module 301.

[0057] The acceleration data of the pressure plate 203 is detected by the accelerometer 302; the number of chest compressions is counted by the counter 305; the pressure data of chest compressions is detected by the flexible pressure sensor 303; and the Bluetooth module 304 enables the cardiopulmonary resuscitation training feedback device to have Bluetooth transmission function.

[0058] In one embodiment, the display mechanism 4 includes two elastic bands 401, a housing 402, a display screen 403, and a plurality of indicator lights 404;

[0059] One end of each of the two elastic bands 401 is fixedly connected to both sides of the housing 201, and the other end of each of the two elastic bands 401 is fixedly connected to the outside of the housing 402. The display screen 403 is installed in the middle of the upper surface of the housing 402, and several display screens 403 are installed on one side of the upper surface of the housing 402.

[0060] The elastic band 401 is stretched by moving the housing 402 so that the hands can be placed between the housing 402 and the flexible pressing pad 202. The stretched elastic band 401 causes the housing 402 to fit against the back of the medical staff's hands, making it easier for the medical staff to observe the data displayed on the display screen 403 on the housing 402.

[0061] In one embodiment, the wrist monitoring mechanism 5 includes an airbag wristband 501, an elastic strap 502, a vibrator 503, and an exhaust valve 504.

[0062] Among them, the two ends of the elastic strap 502 are fixedly connected to the two ends of the airbag wristband 501, the vibrator 503 is installed in the middle of the inner side wall of the airbag wristband 501, the electrical output end of the central control module 301 is electrically connected to the electrical input end of the vibrator 503 through the wire, one end of the exhaust valve 504 is connected to one side of the outer side wall of the airbag wristband 501, and the other side of the outer side wall of the exhaust valve 504 is connected to the air injection mechanism 6.

[0063] The air injection mechanism 6 includes a one-way valve 601, an air cylinder 602, a slide 603, a sealing gasket 604, a second spring 605, and a pressure rod 606;

[0064] One end of the one-way valve 601 is connected to the side of the outer wall of the airbag wristband 501 away from the exhaust valve 504. One end of the air cylinder 602 is threadedly connected to one end of the one-way valve 601. The outer wall of the slide 603 is slidably connected to the inner wall of the air cylinder 602. The inner wall of the sealing gasket 604 is fixedly connected to one side of the outer wall of the slide 603. One end of the pressure rod 606 passes through the inner wall of the air cylinder 602 and is fixedly connected to one side of the slide 603. One end of the second spring 605 is fixedly connected to one side of the inner wall of the air cylinder 602, and the other end of the second spring 605 is fixedly connected to one side of the slide 603.

[0065] The air cylinder 602 is connected to the one-way valve 601 via a threaded connection. Then, the sliding frame 603 is moved by the moving pressure rod 606. The moving sliding frame 603, in conjunction with the sealing gasket 604 and the one-way valve 601, injects air from the air cylinder 602 into the airbag-type wristband 501. Simultaneously, the moving sliding frame 603 stretches the second spring 605, and a vibrator 503 provides vibration alerts to the wrist of the medical personnel. After daily training, the wrist monitoring mechanism 5 can be fitted onto the wrist of the human body model 101, as detailed below. Figure 1 As shown.

[0066] In one embodiment, both locking mechanisms 7 include three locking holes 701, three locking blocks 702, a pressure guide plate 703, three third springs 704, a sliding plate 705, a connecting plate 706, a stepped slide 707, and a guide groove 708.

[0067] Among them, three locking holes 701 are all opened on one side of the housing 201, the outer sidewalls of the three locking blocks 702 are slidably connected to the inner sidewalls of the three locking holes 701 respectively, the pressure guide plate 703 is fixedly connected to the end of the three locking blocks 702 away from the locking holes 701, and the outer sidewall of the pressure guide plate 703 is slidably connected to the inner sidewall of the mounting base 102, one end of each of the three third springs 704 is fixedly connected to one side of the pressure guide plate 703, and the other end of each of the three third springs 704 is fixedly connected to the inner sidewall of the mounting base 102, and the connecting plate 706... One end of the connecting plate 706 is fixedly connected to the middle of one side of the pressure guide 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. The end of the connecting plate 706 away from the pressure guide plate 703 passes through the mounting base 102 and extends into the sliding plate 705. The stepped slide groove 707 is opened in the middle of the inner side wall of the sliding plate 705. The inner side wall of the stepped slide groove 707 is slidably connected to the outer side wall of the connecting plate 706.

[0068] By pushing the slide plate 705 to slide in the guide groove 708, the stepped slide groove 707 in the slide plate 705 drives the connecting plate 706 to move. The moving connecting plate 706 drives the pressure guide plate 703 to move. The moving pressure guide plate 703 drives the locking block 702 to slide out from the locking hole 701 and drives the third spring 704 to compress, thereby releasing the limit on the housing 201.

[0069] In operation, when performing CPR training, the movable housing 402 stretches the elastic band 401, allowing the hands to be placed between the housing 402 and the flexible pressure pad 202. Pressing the flexible pressure pad 202 then moves the pressure plate 203, which in turn moves the support block 204 and the accelerometer 302. The accelerometer 302 detects the acceleration data of the pressure plate 203 and sends the results back to the central control module 301. The moving support block 204 moves the first spring 206, which in turn compresses the sleeve 202. Compression is performed at 05 to buffer the pressure. Then, the pressure is transmitted to the housing 201 through the sleeve 205 and the support plate 207. The housing 201 drives the flexible pressure sensor 303 and the sponge pad 81 to squeeze the bottom of the mounting base 102. The force is then transmitted to the chest of the human model 101 through the mounting base 102. The sponge pad 81 is compressed and deformed under the pressure. The flexible pressure sensor 303 is used to detect the pressure data between the housing 201 and the mounting base 102 and feeds the detection result back to the central control module 301.

[0070] After the chest compression is completed, the compressed first spring 206 pushes the support block 204 to move in the opposite direction. The moving support block 204 pushes the pressure plate 203 to reset the support block 204 and the accelerometer 302, so as to perform cyclic compression operation. The counter 305 is used to increment the count after a chest compression is completed and reset. The ventilation ratio of the detachable auxiliary mechanism 2 is controlled by counting.

[0071] The central control module 301 is used to receive 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 activates the indicator light 404 to remind medical staff to correct their cardiopulmonary resuscitation training movements.

[0072] When the disassembly auxiliary mechanism 2 needs to be removed from the mounting base 102, the sliding plate 705 is pushed to slide in the guide groove 708. The stepped slide groove 707 in the sliding plate 705 drives the connecting plate 706 to move. The moving connecting plate 706 drives the pressure guide plate 703 to move. The moving pressure guide plate 703 drives the locking block 702 to slide out from the locking hole 701 and drives the third spring 704 to compress, so as to release the limit on the housing 201. After the housing 201 is removed from the mounting base 102, the sliding plate 705 is moved in the opposite direction to reset it. Then, the compressed third spring 704 pushes the pressure guide plate 703 to drive the locking block 702 to reset.

[0073] When performing cardiopulmonary resuscitation (CPR), the movable housing 201 moves the sponge pad 81 to fit the designated position on the patient's chest. Then, the movable airbag wristband 501, together with the elastic strap 502, puts the vibrator 503 on the medical staff's wrist. The above operation is then repeated. The detachable auxiliary mechanism 2, together with the feedback detection mechanism 3, is used to perform CPR and check and display relevant data. When the data detected by the accelerometer 302 and the flexible pressure sensor 303 exceeds the threshold, the central control module 301 activates the indicator light 404 and the vibrator 503. The indicator light 404 provides a light prompt to the medical staff, and the vibrator 503 vibrates to provide wrist vibration prompts to the medical staff.

[0074] The inflation mechanism 6 controls the expansion range of the airbag wristband 501 to accommodate different users. When adjustment of the expansion range is required, the air cylinder 602 is connected to the one-way valve 601 via a threaded connection. Then, the pressure rod 606 moves the slide 603, which in turn moves the sealing gasket 604 in conjunction with the one-way valve 601 to inject air from the air cylinder 602 into the airbag wristband 501. Simultaneously, the moving slide... The frame 603 drives the second spring 605 to stretch. When the pressure rod 606 needs to be reset, the stretched second spring 605 drives the slide 603 to move in the opposite direction. The negative pressure in the air cylinder 602 causes the sealing gasket 604 to deform, so that external air can fill the space between the sealing gasket 604 and the air cylinder 602. This allows the air injection mechanism 6 to repeatedly inject air into the airbag wristband 501. After inflation is complete, the air cylinder 602 can be detached from one end of the one-way valve 601 using threads. The exhaust valve 504 is used to expel air from the airbag wristband 501, so that the inflated airbag wristband 501 can contract to fit different people.

[0075] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
