[0002] Traditional cardiopulmonary resuscitation relies primarily on manual chest compressions by medical staff. However, manual compressions often struggle to maintain a stable compression frequency and depth over extended periods. Medical staff are prone to fatigue, especially during prolonged resuscitation operations, which can lead to a gradual decline in compression quality and compromise resuscitation effectiveness.

With advancements in mechanical manufacturing and engineering technology, simple mechanical structures have emerged to simulate chest compressions.

[0003] The existing new mechanical compression device for emergency departments mainly consists of a compression head, a power system and a control system. The compression head is usually made of soft and elastic material. Its shape design conforms to the physiological curve of the human chest to ensure that the force can be evenly transmitted to the sternum during the compression process, reducing damage to the soft tissue of the chest. The working principle is to control the start and stop of the device through the control system, adjust the parameters of the device, and then use the power system to drive the compression head to move and perform compression operations on the patient.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figure 1-Figure 3The utility model provides an embodiment: a novel mechanical pressing device for emergency department, including a fixed platform 1 and a pressing air cushion 33. The interior of the fixed platform 1 is fixedly connected to a shell 2, and the shell 2 is used to protect the internal mechanism to avoid corrosion damage. The bottom of the shell 2 is slidably connected to a connecting column 8, and the bottom of the connecting column 8 is fixedly connected to a connecting plate 9. The connecting column 8 drives the connecting plate 9 to realize the pressing action. The bottom of the connecting plate 9 is fixedly connected to a telescopic rod 10 and two fixed blocks 11. A fixed rod 12 is fixedly connected between the two fixed blocks 11. The outer periphery of the fixed rod 12 is provided with a spring 2 13. The outer periphery of the fixed rod 12 is slidably connected to an extrusion slider 14. When the extrusion slider 14 moves inward, the spring 2 13 will give it a resisting force to buffer the downward pressing action. The bottom of the squeeze slider 14 is rotatably connected to a connecting rod 16. The bottom of the telescopic rod 10 is fixedly connected to a pressing plate 15. One end of the connecting rod 16 is rotatably connected to the top of the pressing plate 15. The squeezing slider 14 and the pressing plate 15 are connected via the connecting rod 16. During compression, the force generated is transmitted through the pressing plate 15 to the squeezing slider 14, providing a cushioning effect. The pressing plate 15 is internally mounted with a quick-change assembly for quickly replacing compression air cushions 33 of different sizes to accommodate patients of varying body shapes. A motor 3 is fixedly connected to the interior of the housing 2. The output end of the motor 3 is fixedly connected to a rocker arm 14. Rotation of the rocker arm 14 by the motor 3 drives the squeezing mechanism. One end of the rocker arm 4 is rotatably connected to a rocker arm 25. Another end of the rocker arm 25 is rotatably connected to a baffle 6. The base of the baffle 6 is fixedly connected to the top of the connecting column 8. The outer periphery of the connecting column 8 is protected by a spring 17. The rotating rocker arm 14, through the rocker arm 25, drives the baffle 6 and the connecting column 8 in a cyclical upward and downward motion, performing the squeezing operation.

[0035] Reference Figure 4-Figure 6The quick-change assembly includes a press-on air cushion 33, with a block 17 fixedly connected to its top. A slide 19 and a slot 20 are defined within the press plate 15. The block 17 slides within the slide 19, engaging the two slots. The slide 19 secures the block 17 within the slot 20. A second telescopic rod 21 is fixedly connected to the inside of the slot 20. A third spring 22 is sheathed around the outer periphery of the second telescopic rod 21. A control panel 23 is fixedly connected to the front of the second telescopic rod 21. When the control panel 23 moves inward, the second telescopic rod 21 exerts an outward force, securing or resetting the position of the control panel 23. The control panel 23 has a control slot 24 formed on its surface. A control rod 25 is rotatably connected to the interior of the slot 20. One end of the control rod 25 slides within the interior of the slot 24. When the block 17 moves inward, it squeezes the control panel 23, causing the control rod 25 to enter the fixed notch of the slot 24. The telescopic rod 21 then applies pressure to the control panel 23, securing the position of the control panel 23. A stopper connecting plate 26 is rotatably connected to the bottom of the control panel 23. A stopper 27 is fixedly connected to the front end of the stopper connecting plate 26. When the control panel 23 moves, it moves the stopper 27 along with it through the stopper connecting plate 26. A sliding post 28 is fixedly connected to the side of the stopper 27, and a slot stopper 29 is fixedly connected to the surface of the slot 20. The sliding post 28 is slidably connected to the interior of the slot stopper 29. A stopper slot 30 is provided inside the slot stopper 29, and the sliding post 28 is slidably connected to the interior of the stopper slot 30. When the control board 23 moves inward with the slot stopper 29, the stopper slot 30 and the sliding post 28 inside the slot stopper 29 cooperate with each other, causing the slot stopper 29 to rise and block the notch of the block 17, thereby achieving the function of fixing the block 17. A sliding baffle 18 is slidably connected to the interior of the pressing plate 15 to block the pressing air cushion 33 fixedly inserted into the slot 20.

[0036] Reference Figure 1 and Figure 4 The surface of the housing 2 is provided with a control panel 31 for controlling the start and stop of the device. The bottom of the fixed platform 1 is provided with universal wheels 32 for moving the device to a suitable position.

[0037] Working principle: When working, first move the device to a position suitable for pressing, pull out the sliding baffle 18 for fixing, and move the block 17 on the pressing air cushion 33 that matches the patient's body shape into the card slot 20 through the block slide 19, squeeze the control board 23 inward, and make the control rod 25 slide into the fixed notch of the control slot 24. The telescopic rod 21 gives the control board 23 an outward force to fix the position of the control board 23. At the same time, when the control board 23 wants to move backward, the block 27 connected to it is pressed by the sliding column 28 and the card slot block 29. In coordination, raise the block 27 to block the gap of the block 17, fix the position of the block 17, insert the sliding baffle 18 to further fix the position of the pressing air cushion 33, and then start the device through the control panel 31. The motor 3 will rotate the rocker arm 1 4, and use the rocker arm 2 5 to control the baffle 6 and the connecting column 8 to perform a cyclic up and down pressing action. When pressing, the force will be transmitted from the pressing air cushion 33 and the pressing plate 15 through the connecting rod 16 to the extrusion slider 14, extrusion spring 2 13, and the spring 2 13 will perform buffering work.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
