Description

Technical Field

[0001] This invention relates to the field of emergency medical rescue equipment technology, and in particular to an artificial respiration device for emergency clinical treatment. Background Technology

[0002] Cardiac arrest is one of the most critical conditions in emergency clinical practice, causing more than 10 million deaths worldwide each year. Effective cardiopulmonary resuscitation (CPR) within the "golden 4 minutes" is the core key to improving patient survival rates.

[0003] In practical applications, existing equipment relies on continuous effort from medical personnel for manual chest compressions, which can easily lead to deviations in compression depth, frequency, and position due to physical exhaustion. Especially during prolonged resuscitation, decreased compression quality directly reduces the success rate of resuscitation. Furthermore, the coordination between artificial respiration and chest compressions is poor, making it difficult to precisely match the timing of ventilation with the compression rhythm, further impacting the rescue outcome. Most existing automated CPR equipment is designed with fixed dimensions, making it impossible to quickly adjust the support width and compression parameters according to the patient's body size (adult / child / obese patient), resulting in poor adaptability to special populations. Moreover, the equipment is bulky and heavy, making folding and storage inconvenient and hindering rapid deployment in space-constrained scenarios such as ambulances and emergency scenes, delaying emergency response and impeding practical application and operation. Summary of the Invention

The tops of the two second support frames 6 are rotatably connected to a cardiopulmonary resuscitation machine 2. The bottoms of the second support frames 6 are provided with slots 18, and the H-shaped blocks 17 are slidably connected to the corresponding slots 18. The top of the cardiopulmonary resuscitation machine 2 is fixedly connected to a respirator 3, and an air bag 4 is provided on the outside of the respirator 3. The bottom of the cardiopulmonary resuscitation machine 2 is installed and connected to a pressing rod 7, and the bottom of the pressing rod 7 is fixedly connected to a pressing seat 8.

[0028] Limiting grooves 19 are provided inside the second support frame 6 on both sides of the slot 18. Limiting plates 21 are slidably connected inside the limiting grooves 19. Locking rods 20 are slidably connected on both sides of the second support frame 6. One end of each locking rod 20 passes through the limiting groove 19 and extends into the inside of the slot 18. The locking rod 20 is fixedly connected to the limiting plate 21 and engages with the corresponding H-shaped block 17.

[0029] A sliding groove 10 is provided on the outer side of the connecting block 9. A bidirectional screw 11 is rotatably connected inside the sliding groove 10. Two threaded blocks 12 are threadedly connected to the outer side of the bidirectional screw 11. Connecting rods 13 are rotatably connected to both sides of the threaded blocks 12. The connecting rods 13 are rotatably connected to the corresponding base 1. A drive motor is provided inside the connecting block 9. The output shaft of the drive motor is fixedly connected to the bidirectional screw 11.

[0030] A pull plate 22 is fixedly connected to one end of the lever 20 and to the outside of the second support frame 6. A spring 23 is fixedly connected between the pull plate 22 and the second support frame 6 and to the outside of the lever 20.

[0031] Both bases 1 have extension grooves 14 on their adjacent sides. Limiting strips 16 are slidably connected inside the extension grooves 14. An extension plate 15 is fixedly connected between the limiting strips 16 and the connecting block 9. An inclined brace 24 is fixedly connected between the cardiopulmonary resuscitation machine 2 and the outside of the respirator 3.

[0032] The airbag 4 is made of transparent medical silicone material, and the airbag 4 and the respirator 3 are connected by a detachable threaded connection, which facilitates quick replacement and disinfection. The bottom surface of the press seat 8 is evenly distributed with anti-slip protrusions, and the press seat 8 and the press rod 7 are fixedly connected by bolts. Different sizes of press seats 8 can be replaced according to the patient's body size.

[0033] The surface of the extension plate 15 is provided with a weight-reducing groove, and the extension plate 15 and the limiting strip 16 are integrally formed, which reduces the overall weight of the device while ensuring structural strength.

[0034] Working principle:

[0035] When in use, if the device needs to be activated at an emergency site, first pull the pull plates 22 on both sides. The pull plates 22 drive the locking rod 20 to slide outwards towards the second support frame 6. At this time, the spring 23 on the outside of the locking rod 20 is stretched and stored. After the locking rod 20 is completely disengaged from the slot of the H-shaped block 17, the locking between the second support frame 6 and the first support frame 5 can be released. Then, lift the second support frame 6 upwards and adjust it to a suitable height for chest compressions. Release the pull plates 22, and the spring 23 will rebound and drive the locking rod 20 to reset, re-engage in the corresponding slot of the H-shaped block 17, completing the height locking of the support structure and putting the cardiopulmonary resuscitation machine 2 in a stable working position. Start the drive motor inside the connecting block 9. The output shaft of the drive motor drives the bidirectional screw 11 to rotate in the slide groove 10. Since the threads of the bidirectional screw 11 are opposite, the two threaded blocks 12 on the outside will move synchronously towards the middle or both sides along the screw. The threaded blocks 12 drive the connecting rod 13 to rotate, and the connecting rod 13 pushes the two bases 1 away from or towards each other. Meanwhile, the extension plate 15 slides within the extension groove 14, and the limiting strip 16 restricts the sliding direction of the extension plate 15 to ensure stability during the adjustment process. This structure allows for precise adjustment of the distance between the two bases 1 according to the patient's body shape, enabling the patient to lie comfortably on the support surface formed by the base 1 and the extension plate 15.

[0036] After placing the patient in position, activate the CPR machine 2. The CPR machine 2 drives the compression lever 7 to move up and down reciprocally. The compression seat 8 at the bottom of the compression lever 7 applies regular pressure to the patient's chest. The anti-slip protrusions on the bottom of the compression seat 8 increase friction with the patient's chest, preventing slippage during compression. The compression seat 8 is fixed to the compression lever 7 with bolts, and different sizes of compression seats 8 can be quickly replaced according to the patient's body size. At the same time, the respirator 3 and the air bag 4 work together. The air bag 4 is made of transparent medical silicone, allowing medical personnel to visually judge the ventilation effect by observing the rise and fall of the air bag. The air bag 4 and the respirator 3 have a detachable threaded connection, which can be quickly disassembled for disinfection or replacement to avoid cross-infection. The diagonal brace 24 further enhances the connection strength between the CPR machine 2 and the respirator 3, preventing structural loosening after long-term use. After the emergency is completed, first turn off the power to the equipment, then pull the pull plate 22 again to unlock the second support frame 6, folding the second support frame 6 downwards so that the slot 18 re-engages into the H-shaped block 17, reducing the overall height of the device. Then the drive motor is started to rotate in the opposite direction. The bidirectional screw 11 drives the threaded block 12 to move towards the middle. The connecting rod 13 pulls the two bases 1 closer to each other. The extension plate 15 is retracted into the extension groove 14. The whole device is folded into a compact state, which is convenient for emergency transport or storage.
