Description

Technical Field

[0001] The present invention particularly relates to a cardiopulmonary resuscitation compression auxiliary device. Background Art

[0002] Cardiac arrest is a serious and life-threatening emergency condition with a high incidence rate worldwide. As a key first aid measure, cardiopulmonary resuscitation (CPR) can significantly improve the patient's chance of survival if implemented within the first few minutes after cardiac arrest. Effective CPR operations include chest compressions and artificial respiration, among which chest compressions are key steps to maintain blood circulation and provide oxygen and nutrients to vital organs. Timely and correct chest compressions can replace the heart's pumping function to a certain extent, buying precious time for subsequent advanced life support.

[0003] In actual emergency scenarios, it is difficult for emergency personnel to maintain a stable and accurate compression frequency and depth by manually performing chest compressions. According to the standards of the International CPR Guidelines, the chest compression frequency for adults should be at least 100 times per minute and the compression depth should be at least 5 cm. However, due to the limitations of manpower, emergency personnel are prone to fatigue after a period of compression, resulting in problems such as decreased compression frequency and insufficient compression depth. Therefore, special compression devices are also used for assistance.

[0004] For example, a Chinese invention patent with publication number CN115844708B provides a cardiopulmonary resuscitation compressor, which, when in use, allows the compression head to press against the heart and lungs of the person being rescued, and the operator holds the grip handle and uses the pushing rod through the abdomen to perform cardiopulmonary resuscitation. During the compression process, the wrist can withstand pressure with the auxiliary rod as a fulcrum, and then the auxiliary rod can withstand the force generated by the wrist, thereby avoiding the wrist hanging in the air and reducing the fatigue of the operator.

[0005] However, most of the existing compression devices for cardiopulmonary resuscitation are stored separately. If an emergency situation occurs during the treatment of a patient and cardiopulmonary compression is required, it takes a certain amount of time to take out and put the compression device, which wastes a lot of time and causes the patient to miss the best first aid time. In view of this, a cardiopulmonary resuscitation compression auxiliary device is proposed to solve the above technical problems. Summary of the invention

Then, one hand drives the mounting seat to slide on the slide rail through the handle, so that the mounting seat moves below the patient's chest cavity, and the other hand moves the mounting plate to move it above the patient's chest cavity and makes the pressing assembly contact with the patient. During the movement of the mounting plate and the mounting seat, the supporting frame slides in the connecting tube and drives the connecting tube to rotate, and then the grip and the handle are released to quickly fix the position of the mounting seat on the slide rail, the position of the connecting tube on the mounting seat and the position of the supporting frame in the connecting tube through the fixing mechanism, and the patient's chest cavity can be pressed by the pressing assembly. Through the setting of the auxiliary device, cardiopulmonary resuscitation compression can be performed within a few seconds of the patient's cardiac arrest, which effectively saves the time for taking and placing and preparing the equipment and avoids the patient missing the best time for first aid.

A group of support rods 9 are hinged on the two groups of support frames 8, and the line connecting the hinge points of the two groups of support frames 8 and the mounting plate 4 is parallel to the support rods 9.

[0050] In the initial state, the patient can lie on the bed 1 for first aid, and the mounting plate 4 is supported by the bracket 31. When cardiopulmonary resuscitation is needed for the patient, the mounting seat 3 can be slid along the slide rail 2, and the mounting plate 4 can be moved at the same time, so that the mounting seat 3 is moved to be aligned with the patient's chest position, and the mounting plate 4 is moved above the patient's chest so that the pressing assembly contacts the patient's chest. The two groups of support frames 8 are always in a parallel state through the arrangement of the support rod 9, and the mounting plate 4 will not flip over during the movement through the arrangement of the two groups of support frames 8. During the movement of the mounting seat 3 and the mounting plate 4, the mounting seat 3 slides on the slide rail 2, the support frame 8 slides in the through groove 12, and drives the connecting tube 11 to rotate on the mounting seat 3.

[0051] like Figures 4 to 6 As shown, in this embodiment, a group of handles 17 are provided on the two groups of connecting tubes 11, and a grip 18 is slidably installed in the handle 17. The grip 18 is connected to the support frame 8, the connecting tube 11 and the slide rail 2 through a fixing mechanism. The fixing mechanism includes a first elastic member 19 provided between the handle 17 and the grip 18, and the two groups of connecting tubes 11 are rotatably provided on the handle 17 respectively. The handle 18 is provided with a first fixing component connected to the support frame 8, and the position of the support frame 8 in the connecting tube 11 can be selectively fixed or released by the first fixing component. The first fixing component includes a wedge block 21 slidably arranged in the handle 17 along the width direction of the handle 17, the wedge block 21 is movably extended into the connecting tube 11, and an inclined track 23 is arranged on the wedge block 21. A driving column 20 is provided on the handle 18, and the driving column 20 is slidably clamped in the inclined track 23. A locking column 14 is slidably arranged in the connecting tube 11 along its axis. A plurality of groups of locking holes 10 are arranged at intervals on the support frame 8, and the locking column 14 can be inserted into the locking hole 10, and the end of the locking column 14 close to the wedge block 21 is a conical surface and abuts against the inclined surface of the wedge block 21. A baffle 15 is provided on the locking column 14, and a second elastic member 16 is provided between the baffle 15 and the inner side of the connecting tube 11.

[0052] In the initial state, the locking column 14 is pushed out by the wedge block 21, and the second elastic member 16 is compressed by the baffle 15. The locking column 14 is clamped in the locking hole 10 to fix the position of the support frame 8 in the connecting tube 11. An arc groove can be provided on the side wall of the connecting tube 11 to accommodate the relative movement of the wedge block 21 and the connecting tube 11. When the position of the pressing assembly needs to be adjusted, the grip 18 and the handle 17 are gripped to drive the driving column 20 to move and compress the first elastic member 19. During the movement, the driving column 20 drives the wedge block 21 to slide through the cooperation with the inclined track 23, so that its end is separated from the locking column 14, and the locking column 14 is retracted and separated from the locking hole 10 under the resetting action of the second elastic member 16, so that the position of the support frame 8 in the connecting tube 11 can be released. After adjusting the position of the mounting plate 4, the grip 18 is released, and each component can be controlled to reset under the action of the first elastic member 19, so that the locking column 14 is clamped in the locking hole 10 again.

[0053] like Figure 5 , 6 As shown, in this embodiment, the fixing mechanism also includes a second fixing component arranged on the handle 18 and connected to the connecting tube 11, and the connecting tube 11 can be selectively fixed or released at the position of the mounting seat 3 through the second fixing component. The second fixing component includes a gear 13 fixedly arranged at the end of the connecting tube 11, and a locking block 22 is arranged on the wedge block 21. The locking block 22 extends out of the handle 17 and is clamped on the gear 13.

[0054] When the wedge block 21 is controlled to be retracted, the locking block 22 is driven to disengage from the gear 13. The connecting tube 11 rotates relative to the handle 17 during the rotation. After the handle 18 is released, the locking block 22 is driven to extend and be clamped on the gear 13 again during the extension of the wedge block 21 to fix the position of the connecting tube 11.

[0055] like Figure 4 , 5 As shown in FIGS. 6 and 7 , in this embodiment, the fixing mechanism further includes a third fixing assembly disposed on the handle 18 and connected to the slide rail 2, and the position of the mounting seat 3 on the slide rail 2 can be selectively fixed or released by the third fixing assembly. The third fixing assembly includes a driving rod 24 disposed on the handle 18 and extending out of the handle 17, a clamping block 28 is disposed on the driving rod 24, a slide groove 29 is arranged through the slide rail 2, and a plurality of groups of clamping grooves 30 are arranged at intervals on the slide groove 29, the driving rod 24 is slidably disposed in the slide groove 29, and the clamping block 28 is clamped in one of the groups of clamping grooves 30.

[0056] In the initial state, the position of the mounting column 3 on the slide rail 2 is fixed by the cooperation of the clamping block 28 and the clamping slot 30. When the handle 18 is held, the driving rod 24 is driven to slide, so that the clamping block 28 is disengaged from the clamping slot 30 to release the position fixation of the mounting seat 3. After adjusting the position of the mounting seat 3, the handle 18 is released, and the clamping block 28 is clamped into the clamping slot 30 again to fix the position of the mounting seat 3. Through the setting of the fixing mechanism, the position of the pressing assembly can be quickly fixed after the pressing assembly is moved to the patient's chest cavity, so as to facilitate cardiopulmonary resuscitation pressing for patients of different body shapes, and the mounting seat 3 is located outside the patient's chest cavity, and the pressing assembly is located directly above the patient's chest cavity. The support frame 8 is arranged vertically on the bed body 1 to improve the stability during pressing.

[0057] like Figure 2 , 3 As shown in Figures 6 and 7, in this embodiment, both ends of the mounting plate 4 are provided with connection units connected to the bed body 1, and the driving rods 24 in the two groups of connection units are connected through a linkage assembly to drive the other group of handles 18 to move relatively when one group of handles 18 moves. The linkage assembly includes a connecting plate 25 whose two ends are respectively fixedly connected to the two groups of mounting seats 3, a driving disk 26 is rotatably provided on the connecting plate 25, and two groups of push rods 27, one end of the two groups of push rods 27 is respectively connected to the two groups of driving rods 24, and the other end is connected to the driving disk 26, and the two groups of push rods 27 are symmetrically arranged along the center of the driving disk 26.

[0058] The two groups of connecting units can improve the stability of the device during the pressing process. In the process of holding one group of handles 18, the driving disk 26 is driven to rotate through the cooperation of the driving rod 24 and the push rod 27. During the rotation of the driving disk 26, the other group of handles 18 can be controlled to slide in the handle 17 through the cooperation of the other group of driving rods 24 and the push rod 27, so that the fixing mechanisms in the two groups of connecting units are released, and then the position of the mounting plate 4 is moved to avoid the mounting plate 4 being offset due to the force during the pressing process.

[0059] like Figure 1 , 2 As shown, in this embodiment, the pressing assembly includes a support plate 5 slidably mounted on a mounting plate 4, a telescopic motor 6 is fixedly mounted on the support plate 5, and a pressing plate 7 is arranged on the output shaft of the telescopic motor 6. After the mounting plate 4 is moved to the chest position of the patient and fixed, the support plate 5 can be slid to move the pressing plate 7 to the pressing position, and then the telescopic motor 6 is controlled to start the pressing plate 7 to perform cardiopulmonary resuscitation on the patient.

[0060] Specific usage and beneficial effects of the present invention:

[0061] When the device is in use, the patient can perform first aid on the bed 1. When cardiopulmonary resuscitation is needed, the patient can hold the grip 18 and the handle 17 to make the grip 18 slide in the handle 17, so as to release the position fixation of the mounting seat 3 on the slide rail 2 through the fixing mechanism, and at the same time release the position fixation of the connecting tube 11 on the mounting seat 3 and the position fixation of the support frame 8 in the connecting tube 11, and then use one hand to drive the mounting seat 3 to slide on the slide rail 2 through the handle 17, so that the mounting seat 3 moves to the bottom of the patient's chest, and use the other hand to move the mounting plate 4 to move it above the patient's chest and make the pressing assembly contact with the patient. During the movement of the mounting plate 4 and the mounting seat 3, the support frame 8 slides in the connecting tube 11 and drives the connecting tube 11 to rotate, and then the grip 18 and the handle 17 are released to quickly fix the position of the mounting seat 3 on the slide rail 2, the position of the connecting tube 11 on the mounting seat 3, and the position of the support frame 8 in the connecting tube 11 through the fixing mechanism, and the patient's chest cavity can be pressed by the pressing component. Through the setting of the auxiliary device, cardiopulmonary resuscitation can be performed within a few seconds of the patient's cardiac arrest, which effectively saves the time for taking and placing and preparing the equipment and avoids the patient missing the best time for first aid.
