An adaptive automatic cardiopulmonary resuscitation (CPR) compression device for emergency use.

Abstract

This invention relates to the field of cardiopulmonary resuscitation (CPR) technology, and more particularly to an adaptive automatic CPR compression device for emergency use. The device includes a stretcher, a hinge plate, a support frame, a mounting plate, a sliding frame, and an automatic compression mechanism. The stretcher has a scissor bracket with rollers connected to its bottom. A sliding frame is mounted on one side of the front of the stretcher via the hinge plate. The sliding frame is slidably mounted on the support frame. A motor is mounted on the outer wall of the sliding frame. The output shaft of the motor is connected to a lead screw, which is threaded onto the mounting plate. The automatic compression mechanism is mounted on the mounting plate. This invention uses a rotating hinge plate to support the support frame across the patient's chest from the left side, placing it on the right side of the stretcher and inserting it into a locking frame. The compression plate presses against the top block, causing the limiting plate to slide down the guide rod, which in turn moves the rack downwards along the slide rail, causing the gear set to rotate. This, in turn, causes the rotating shaft to rotate the clamping plate, thus automatically immobilizing the patient's limbs.

Description

Technical Field

[0001] This invention relates to the field of cardiopulmonary resuscitation (CPR) technology, and more particularly to an adaptive automatic CPR compression device for emergency use. Background Technology

[0002] Automatic cardiopulmonary resuscitation (CPR) devices, also known as CPR assist devices attached to automated external defibrillators (AEDs) or stand-alone CPR machines, are medical devices specifically designed to provide continuous, accurate, and efficient chest compressions in emergency situations. These devices can replace manual chest compressions in the event of cardiac arrest to maintain blood circulation and buy valuable time for subsequent medical intervention.

[0003] However, existing automated CPR devices still have some shortcomings in practical applications: First, the devices have limited adaptability to individual differences. When faced with patients of extreme body size, special chest structures, or specific pathological conditions (such as obesity, thinness, prominent sternum, post-thoracic surgery changes, rib fractures, pleural effusion, etc.), the devices often fail to provide precise and individualized compression effects. This may lead to inaccurate compression depth, failing to achieve the ideal hemodynamic effect and potentially causing unnecessary additional harm to the patient. Second, existing automated CPR devices are inadequate in terms of patient immobilization and ease of operation. In emergency and stressful rescue scenarios, accurately and quickly placing and securing the device in the appropriate position on the patient's chest is crucial, especially for patients who are large, have difficulty moving, or are in complex environments (such as confined spaces or uneven ground). Correct placement and fixation of the device are particularly important. In practice, some devices are still prone to positional deviation or poor fit, affecting the compression effect. These factors may not only delay precious rescue time but also reduce the quality and success rate of CPR. Therefore, improving the individual adaptability and ease of operation of equipment to better serve cardiopulmonary resuscitation is an urgent problem to be solved. Summary of the Invention

[0004] To overcome the shortcomings of existing automatic cardiopulmonary resuscitation (CPR) compression devices, such as limited adaptability to individual differences in practical applications and the tendency for some devices to deviate from their intended position or have poor fit during operation, thus affecting the compression effect, this invention provides an adaptive automatic CPR compression device for emergency use.

[0005] The technical solution is: an adaptive cardiopulmonary resuscitation automatic compression device for emergency use, comprising a stretcher, a scissor bracket, a hinge plate, a support frame, a mounting plate, a sliding frame, an automatic compression machine, a lead screw, and a motor. The bottom of the stretcher is connected to a scissor bracket with rollers. The front side of the stretcher is connected to a support frame via a hinge plate. A sliding frame is slidably mounted on the support frame. A motor is mounted on the outer wall of the sliding frame. The output shaft of the motor is connected to a lead screw. A mounting plate is threaded onto the lead screw. An automatic compression machine is mounted on the mounting plate.

[0006] Furthermore, preferably, the device further includes a guide rod, a limiting plate, a slide rail, a second spring, a guide post, an adjusting plate, a rotating shaft, a clamping plate, a gear set, a rack, a connecting plate, and a pressure plate. The bottom of the stretcher is slidably connected to the limiting plate via the guide rod. Two sets of slide rails are symmetrically arranged on the left and right sides of the middle and rear of the limiting plate. Adjusting plates are slidably connected to each slide rail. Each adjusting plate is rotatably connected to a clamping plate via a rotating shaft. A guide post is connected to the front side wall of the adjusting plate via a connecting plate. A pressure plate is slidably sleeved on the guide post. A second spring is connected between the pressure plate and the guide post. A rack is connected to the upper part of the pressure plate. The lower part of the pressure plate is slidably connected to the slide rail. A gear set that meshes with the rack is connected to the end of the rotating shaft of the clamping plate.

[0007] Furthermore, it is particularly preferred that the device also includes a locking rod and a locking hole, each slide rail is slidably connected to the locking rod via a sliding block, a first spring is connected between the locking rod and the sliding block, the sliding block is fixedly connected to the adjusting plate, and the limiting plate is provided with a locking hole that matches the locking rod.

[0008] Furthermore, it is particularly preferred that the device also includes a first connecting rod and a handle, with the first connecting rod correspondingly connected between the two pairs of locking rods on the front and rear sides, and a handle connected to one side of the first connecting rod.

[0009] Furthermore, it is particularly preferred that the device further includes a cylinder, a slider, and a second connecting rod. The cylinder is mounted on the scissor bracket, and the telescopic end of the cylinder is connected to the upper part of the scissor bracket via the second connecting rod. The upper part of the scissor bracket is slidably connected to the stretcher via the slider.

[0010] Furthermore, it is particularly preferred that the device also includes a pressing plate and a top block, the limiting plate is equipped with a top block for pushing it down along the guide rod, the support frame is connected to a pressing plate for pressing the top block, and the stretcher above the top block is provided with a through groove for the pressing plate to pass through.

[0011] Furthermore, it is particularly preferred that the device further includes a locking frame, a first locking plate, and a third spring. The right side of the stretcher is connected to a locking frame that is locked to the pressing plate. The left side of the locking frame is slidably connected to a first locking plate for locking the support frame. A third spring is connected between the first locking plate and the locking frame.

[0012] Furthermore, it is particularly preferred that the device further includes a connecting plate, a second locking plate, and a fourth spring, wherein the connecting plate is connected to the side of the scissor bracket, the left side of the connecting plate is slidably connected to a second locking plate for engaging the support frame, and a fourth spring is connected between the second locking plate and the connecting plate.

[0013] The present invention has the following advantages: The present invention uses a rotating hinge plate to support the patient's chest from the left side across the right side of the stretcher and insert it into the locking frame. By pressing the plate and the top block, the limiting plate is driven to slide down the guide rod, causing the pressure plate and rack to move downward along the slide rail, thereby driving the gear set to rotate. This causes the rotating shaft to drive the clamping plate to rotate, thus automatically fixing the patient's limbs. By extending or shortening the cylinder, the horizontal crossing angle of the scissor bracket can be increased or decreased, thereby reducing the height of the stretcher to better lift the patient onto the stretcher, facilitating emergency treatment and patient transfer.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. All embodiments of the present invention are illustrated in the accompanying drawings. Figure 1 The direction is described with reference.

[0027] Example 1: An adaptive automatic cardiopulmonary resuscitation (CPR) compression device for emergency use, such as... Figure 1-2As shown, the device includes a stretcher 1, a scissor bracket 9, a hinge plate 2, a support frame 3, a mounting plate 4, a sliding frame 5, an automatic cardiopulmonary resuscitation (CPR) machine 6, a lead screw 7, and a motor 8. The bottom of the stretcher 1 is connected to the scissor bracket 9 with rollers. The front side of the stretcher 1 is connected to the support frame 3 via the hinge plate 2. The sliding frame 5 is slidably mounted on the support frame 3. The motor 8 is mounted on the outer wall of the sliding frame 5. The output shaft of the motor 8 is connected to the lead screw 7. The lead screw 7 is threadedly connected to the mounting plate 4. The automatic cardiopulmonary resuscitation (CPR) machine 6 is mounted on the mounting plate 4. When performing CPR on an emergency patient, first position the patient's head towards... Lay the patient flat on stretcher 1. Rotate hinge plate 2 to support the support frame 3 across the patient's chest from the left side, placing it on the right side of stretcher 1. Turn on motor 8 to adjust the vertical position of automatic chest compression machine 6 on sliding frame 5, thereby adjusting the compression depth. Sliding frame 5 along support frame 3 allows for fine adjustment of the compression position of automatic chest compression machine 6 in front of the patient's chest, adapting to different lying positions and compression needs. This eliminates the need to move the patient again. After adjusting the compression position, turn on automatic chest compression machine 6 to perform automatic CPR on the patient.

[0028] like Figures 3-6 As shown, the device also includes a guide rod 102, a limiting plate 10, a slide rail 11, a guide post 143, a second spring 144, an adjusting plate 141, a rotating shaft 13, a clamping plate 14, a gear set 16, a rack 17, a connecting plate 142, and a pressure plate 171. The bottom of the stretcher 1 is slidably connected to the limiting plate 10 via the guide rod 102. Two sets of slide rails 11 are symmetrically arranged on the middle and rear of the limiting plate 10. Adjusting plates 141 are slidably connected to each slide rail 11. Each adjusting plate 141 is rotatably connected to a clamping plate 14 via a rotating shaft 13. The front side wall of the adjusting plate 141 is connected to a guide post 143 via a connecting plate 142. The pressure plate 171 is slidably sleeved on the guide post 143. A second spring 144 is connected between the pressure plate 171 and the guide post 143. A rack is connected to the upper part of the pressure plate 171. 17. The lower part of the pressure plate 171 is slidably connected to the slide rail 11. The pressure plate 171 can slide up and down along the slide rail 11, and can also slide back and forth along the slide rail 11. The end of the rotating shaft 13 of the clamping plate 14 is connected to a gear set 16 that meshes with the rack 17. When the pressure plate 171 is pressed down along the guide post 143, it will drive the rack 17 on the upper part of the pressure plate 171 to mesh with the gear set 16, thereby causing the rotating shaft 13 to drive the clamping plate 14 to rotate, thereby fixing the patient's limbs. When the pressure plate 171 is no longer pressed, the pressure plate 171 and the rack 17 move up along the guide post 143 under the action of the second spring 144 to reset the slide rail 11, thereby causing the gear set 16 to reverse, thereby causing the rotating shaft 13 to drive the clamping plate 14 to rotate in the opposite direction, thereby no longer fixing the patient's limbs.

[0029] like Figure 4As shown, the device also includes a locking rod 12 and a locking hole 15. The slide rails 11 are all slidably connected to the locking rod 12 via sliding blocks 121. A first spring 122 is connected between the locking rod 12 and the sliding block 121. The sliding block 121 is fixedly connected to the adjusting plate 141. The limiting plate 10 has a locking hole 15 that matches the locking rod 12. When the adjusting plate 141 is pushed to move along the slide rail 11, it will drive the locking rod 12 to slide along the slide rail 11, so that the locking rod 12 can be aligned and inserted into the locking hole 15 on the stretcher 1, so as to fix the position of the adjusting plate 141 and the clamping plate 14. It should be noted that the height of the adjusting plate 141, the gear set 16 and the rack 17 during actual installation does not exceed the upper surface of the stretcher 1, so as to keep the upper surface of the stretcher 1 flat.

[0030] Example 2: Based on Example 1, such as Figure 4 As shown, the device also includes a first connecting rod 18 and a handle 19. The first connecting rod 18 is connected to each of the two pairs of locking rods 12 on the front and rear sides. The handle 19 is connected to one side of the first connecting rod 18. By moving the handle 19 along the slide rail 11 in the front and rear direction, the locking rod 12, the adjusting plate 141 and the clamp 14 can be moved along the slide rail 11 in the front and rear direction, so that the front and rear position of the clamp 14 can be easily adjusted to accommodate patients of different heights, so as to quickly fix the patient's limbs.

[0031] like Figure 7 As shown, the device also includes a cylinder 20, a slider 21, and a second connecting rod 22. The cylinder 20 is mounted on the scissor bracket 9. The telescopic end of the cylinder 20 is connected to the upper part of the scissor bracket 9 through the second connecting rod 22. The upper part of the scissor bracket 9 is slidably connected to the stretcher 1 through the slider 21. When the cylinder 20 is extended, the horizontal crossing angle of the scissor bracket 9 can be increased, thereby raising the height of the stretcher 1. When the cylinder 20 is shortened, the horizontal crossing angle of the scissor bracket 9 can be decreased, thereby lowering the height of the stretcher 1, so as to better lift the patient onto the stretcher, facilitating emergency treatment and patient transfer.

[0032] like Figures 8-9As shown, the device also includes a pressing plate 23 and a top block 24. A top block 24 is mounted on the limiting plate 10 for pushing it down along the guide rod 102. A pressing plate 23 for pressing the top block 24 is connected to the support frame 3. A through slot 241 for the pressing plate 23 to pass through is provided on the stretcher 1 above the top block 24. When the support frame 3 crosses the patient's chest from the left side of the stretcher 1 and supports the right side of the stretcher 1, the pressing plate 23 will press against the top block 24, thereby causing the limiting plate 10 to slide down along the guide rod 102, and thus causing the rack 17 to slide along the slide rail 102. 1. Moving downwards causes the gear set 16 to rotate, which in turn causes the rotating shaft 13 to rotate the clamp 14, thereby fixing the patient's limbs. After the support frame 3 is removed, the pressing plate 23 no longer presses against the top block 24, causing the rack 17 to move upwards along the slide rail 11 and reset under the action of the second spring 144, which in turn causes the gear set 16 to rotate, which in turn causes the rotating shaft 13 to rotate the clamp 14 in the opposite direction, thereby no longer fixing the patient's limbs, and at the same time, it will cause the limiting plate 10 to slide upwards along the guide rod 102 and reset.

[0033] like Figures 9-10 As shown, the device also includes a locking frame 25, a first locking plate 26, and a third spring 27. The right side of the stretcher 1 is connected to the locking frame 25, which is locked to the pressing plate 23. The left side of the locking frame 25 is slidably connected to the first locking plate 26 for locking the support frame 3. The first locking plate 26 and the locking frame 25 are connected to the third spring 27. When the support frame 3 crosses the patient's chest from the left side of the stretcher 1 and supports the right side of the stretcher 1, the pressing plate 23 is inserted into the locking frame 25. Under the pressure of the pressing plate 23, the first locking plate 26 first slides outward along the locking frame 25, and then the pressing plate 23 is locked under the action of the third spring 27, thereby keeping the position of the automatic pressing machine 6 fixed.

[0034] like Figures 10-11 As shown, the device also includes a connecting plate 28, a second locking plate 29, and a fourth spring 30. The connecting plate 28 is connected to the side of the scissor bracket 9. The second locking plate 29 for locking the support frame 3 is slidably connected to the left side of the connecting plate 28. The fourth spring 30 is connected between the second locking plate 29 and the connecting plate 28. When the automatic pressing machine 6 is not in use, the support frame 3 and the hinge plate 2 are folded together and hung on one side of the stretcher 1. The support frame 3 is pushed to lock into the inside of the second locking plate 29, thereby fixing and limiting the support frame 3. The support frame 3 will not unfold around the hinge plate 2, thereby realizing the storage and fixing of the support frame 3.

[0035] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
