Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a backplate rebound device of a cardiopulmonary resuscitation machine. Background Technique

[0002] With the continuous development of medical technology, cardiopulmonary resuscitation machines play an increasingly important role in first aid and resuscitation treatment. The backplate of a cardiopulmonary resuscitation machine is used to pad under the patient's back. After the cardiopulmonary resuscitation machine is installed, it cooperates with the cardiopulmonary resuscitation machine to press the patient's chest to perform cardiopulmonary resuscitation on the patient.

[0003] However, during a long-term cardiopulmonary resuscitation process, since the patient is in a state of being pressed for a long time, the ability of the patient's chest to rebound by itself will gradually decrease, thereby reducing the success rate of cardiopulmonary resuscitation rescue. For this reason, we propose a backplate rebound device of a cardiopulmonary resuscitation machine. Content of the Utility Model

[0004] One technical problem to be solved by this application is: during a long-term cardiopulmonary resuscitation process, since the patient is in a state of being pressed for a long time, the ability of the patient's chest to rebound by itself will gradually decrease, thereby reducing the success rate of cardiopulmonary resuscitation rescue.

[0005] To solve the above technical problem, the embodiment of this application provides a backplate rebound device of a cardiopulmonary resuscitation machine, including a backplate body fixedly connected with connecting shafts at both ends. The backplate body has an arc-shaped structure. Two groups of support protrusions are symmetrically installed at the bottom of the backplate body. It also includes:

[0006] Two grooves, both of which are opened on the upper surface of the backplate body, and the two grooves are symmetrically arranged, and

[0007] Two movable rotating plates, the two movable rotating plates are correspondingly arranged in the two grooves. First rotating shafts are fixedly connected to the side walls of the adjacent ends of the two movable rotating plates. One end of the first rotating shaft away from the movable rotating plate is rotatably connected to the side wall of the groove, and

[0008] A first torsion spring, the first torsion spring is sleeved on the first rotating shaft. One end of the first torsion spring is fixedly connected to the movable rotating plate, and the other end of the first torsion spring is fixedly connected to the inner wall of the groove, and

[0009] Two locking structures, the two locking structures are respectively installed at both ends of the backplate body, and are used to limit one end of the two movable rotating plates away from the first rotating shaft.

[0010] Preferably, two through holes penetrating the backplate body in the height direction of the backplate body are opened in the middle section of the backplate body.

[0011] Preferably, a gap is left between the peripheral side of the movable rotating plate and the inner wall of the groove, and the width of the gap is not greater than 0.5 cm.

[0012] Preferably, receiving grooves are provided on both sides of one end of the movable rotating plate connected to the first rotating shaft, and one end of the first torsion spring close to the movable rotating plate is embedded in the receiving groove and fixedly connected to the inner wall of the receiving groove.

[0013] Preferably, a slot is formed on the upper surface of one end of the two movable rotating plates which are away from each other, and the locking structure is connected with the movable rotating plates through the slot.

[0014] Preferably, cavities are provided at both ends of the back panel body, and a group of support plates are fixedly connected in each of the two cavities. The locking structure is arranged between the two support plates in each group, one end of the locking structure extends into the card slot to form a card block, and the other end of the locking structure extends in the opposite direction to form a pressure plate. A second rotating shaft is fixedly connected to the middle section of the locking structure, and the second rotating shaft is rotatably connected to the support plate at one end away from the locking structure. A second torsion spring is sleeved on the second rotating shaft, and its two ends are respectively fixedly connected to the locking structure and the support plate.

[0016] The utility model has at least the following beneficial effects:

[0017] 1. Two grooves are provided on the upper surface of the back plate body, and movable rotating plates are rotatably connected in the two grooves. The adjacent side walls of the two movable rotating plates are fixedly connected to the inner wall of the groove through the first torsion spring. When the cardiopulmonary resuscitation machine presses the patient's chest, the movable rotating plate is rotated downward by force and embedded in the groove. After pressing, the first torsion spring can drive the two movable rotating plates to rotate in the opposite direction under the action of its own elastic force, and push the patient's chest upward for effective rebound, thereby improving the patient's chest rebound ability and greatly improving the rescue success rate of cardiopulmonary resuscitation;

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Embodiment 1

[0028] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0029] A backboard rebound device for a cardiopulmonary resuscitation machine, including a backboard body 1 fixedly connected with connecting shafts 2 at both ends. The backboard body 1 is in an arc-shaped structure. Two groups of support protrusions 3 are symmetrically installed at the bottom of the backboard body 1. It further includes:

[0030] Two grooves 5 opened on the upper surface of the backboard body 1, and the two grooves 5 are symmetrically arranged, and

[0031] Two movable rotating plates 6 correspondingly arranged in the two grooves 5. First rotating shafts 7 are fixedly connected to the side walls of the adjacent ends of the two movable rotating plates 6. One end of the first rotating shaft 7 away from the movable rotating plate 6 is rotatably connected to the side wall of the groove 5, enabling the movable rotating plate 6 to rotate out of the groove 5 around the first rotating shaft 7, and

[0032] A first torsion spring 8 sleeved on the first rotating shaft 7, one end of the first torsion spring 8 is fixedly connected to the movable rotating plate 6, and the other end of the first torsion spring 8 is fixedly connected to the inner wall of the groove 5. When the first torsion spring 8 is not stressed, the free ends of the two movable rotating plates 6 are located outside the groove 5, and

[0033] Two locking structures 12, the two locking structures 12 are respectively installed at both ends of the backplate body 1, and are used for limiting one end of the two movable rotating plates 6 away from the first rotating shaft 7, so as to facilitate the storage of the movable rotating plates 6 into the groove 5. It further includes:

[0034] Two through holes 4 penetrating the backplate body 1 along the height direction of the backplate body 1 are opened in the middle section of the backplate body 1. By setting the through holes 4, the self-weight of the backplate body 1 is reduced, which is convenient for medical staff to carry the backplate body 1 out for rescue, and

[0035] A gap is left between the circumferential side of the movable rotating plate 6 and the inner side wall of the groove 5, and the width of the gap is not greater than 0.5 cm, and

[0036] Receiving grooves are opened on both sides of the end of the movable rotating plate 6 connected to the first rotating shaft 7. One end of the first torsion spring 8 close to the movable rotating plate 6 is embedded in the receiving groove and fixedly connected to the inner wall of the receiving groove. It further includes:

[0037] Card slots 9 are opened on the upper surfaces of the ends of the two movable rotating plates 6 away from each other, and the locking structure 12 is clamped with the movable rotating plate 6 through the card slots 9, and

[0038] Cavities 10 are opened at both ends of the backplate body 1. A group of support plates 11 are fixedly connected in the two cavities 10. The locking structure 12 is arranged between the two support plates 11 in each group. One end of the locking structure 12 extends into the card slot 9 to form a clamping block 13, and the other end of the locking structure 12 extends in the opposite direction to form a pressing plate 14. A second rotating shaft 15 is fixedly connected to the middle section of the locking structure 12. The end of the second rotating shaft 15 away from the locking structure 12 is rotatably connected to the support plate 11. A second torsion spring 16 with both ends fixedly connected to the locking structure 12 and the support plate 11 respectively is sleeved on the second rotating shaft 15.

[0039] In use, the patient lies flat on the backboard body 1. Then, both sides of the cardiopulmonary resuscitation machine are fixed to the connecting shafts 2 provided at both ends of the backboard body 1 through connecting pieces. When using the connecting pieces, the pressing plate 14 is pushed downward, driving the locking structure 12 to rotate around the second rotating shaft 15, so that the clamping block 13 moves upward and disengages from the clamping groove 9 opened at the end of the movable rotating plate 6. At this time, the movable rotating plate 6 is driven by the elastic force of the first torsion spring 8 to rotate upward around the first rotating shaft 7 and pop out of the groove 5. At this time, the medical staff can start the cardiopulmonary resuscitation machine to perform cardiopulmonary resuscitation on the patient's chest. When the cardiopulmonary resuscitation machine presses the patient's chest cavity, the movable rotating plate 6 rotates downward under the action of the upward pressure and is embedded into the groove 5. After pressing, the first torsion spring 8 can drive the two movable rotating plates 6 to rotate in the reverse direction under its own elastic force, pushing the patient's chest cavity upward for effective rebound, thus avoiding as much as possible the problem that the patient's ability to rebound by himself gradually decreases under the state of long-term pressing, resulting in a reduction in the success rate of cardiopulmonary resuscitation rescue.

[0040] Embodiment 2

[0041] Please refer to Figure 6 , the present utility model provides a technical solution:

[0042] Different from Embodiment 1, this solution provides another implementation manner of the backboard rebound device of the cardiopulmonary resuscitation machine:

[0043] A backboard rebound device of a cardiopulmonary resuscitation machine, including a backboard body 1 fixedly connected with connecting shafts 2 at both ends. The backboard body 1 is in an arc structure. Two groups of support protrusions 3 are symmetrically installed at the bottom of the backboard body 1. It further includes:

[0044] Two grooves 5 opened on the upper surface of the backboard body 1, and the two grooves 5 are symmetrically arranged, and

[0045] Two movable rotating plates 6 correspondingly arranged in the two grooves 5. First rotating shafts 7 are fixedly connected to the side walls of the adjacent ends of the two movable rotating plates 6. One end of the first rotating shaft 7 away from the movable rotating plate 6 is rotatably connected to the side wall of the groove 5, so that the movable rotating plate 6 can rotate out of the groove 5 around the first rotating shaft 7, and

[0046] A first torsion spring 8 sleeved on the first rotating shaft 7. One end of the first torsion spring 8 is fixedly connected to the movable rotating plate 6, and the other end of the first torsion spring 8 is fixedly connected to the inner wall of the groove 5. When the first torsion spring 8 is not stressed, the free ends of the two movable rotating plates 6 are located outside the groove 5, and

[0047] Two locking structures 12 are respectively installed at both ends of the backboard body 1 for limiting one end of the two movable rotating plates 6 away from the first rotating shaft 7, facilitating the storage of the movable rotating plates 6 into the grooves 5. It further includes:

[0048] Above each of the two movable turning plates 6, there is a rubber pad 17 that fits the upper surface of the movable turning plate 6, and the rubber pad 17 is bonded to the movable turning plate 6.

[0049] By pasting the rubber pad 17 on the upper surface of the movable turning plate 6, the rubber pad 17 is used for buffering when the patient's chest cavity is compressed, protecting the part where the patient fits with the movable turning plate 6, and trying to avoid the problem that when the patient is in a compressed state, hard extrusion occurs between the movable turning plate 6 and the skin on the patient's back and both sides of the chest cavity, which is likely to cause damage to the patient.
