When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0037] The present invention provides a strap structure 100 for use in a cardiopulmonary resuscitation machine.

[0038] In the embodiment of the present invention, Figures 1 to 7As shown, the strap structure 100 includes a base plate 1 and a leg device 2, the leg device 2 includes a leg 21 and a fastener 22, the leg 21 is rotatably connected to the base plate 1, the leg 21 is provided with a accommodating cavity 21a, and the fastener 22 is movably inserted in the accommodating cavity 21a; the two opposite side walls of the accommodating cavity 21a are defined as matching side walls, each of the matching side walls is provided with a plurality of snap-in grooves 21b arranged along the moving direction of the fastener 22; the fastener 22 is provided with two groups of snap-in parts 23, each group of snap-in parts 23 is arranged corresponding to one of the matching side walls, and the snap-in parts 23 are snap-fitted with the snap-in grooves 21b.

[0039] In this embodiment, the leg device 2 and the base plate 1 are foldable by rotating the leg 21 and the base plate 1, which can reduce the size of the strap structure 100 and facilitate vehicle loading and transportation. By the movable setting of the fastener 22 and the snap-fitting of the clamping member 23 and the clamping groove 21b, the fastener 22 drives the clamping member 23 to move under the pull of an external force. When the clamping member 23 is clamped in different clamping grooves 21b, the length of the fastener 22 extending out of the accommodating cavity 21a is different, so as to adjust the length of the strap structure 100 and achieve the purpose of adjusting the strap structure 100 according to the size of the human body. The fastener 22 and the connection method of the fastener 22 and the leg 21 of the present invention can replace the cloth strap and the length adjustment method of the cloth strap in the prior art, so as to achieve the purpose of improving the accuracy of cardiopulmonary resuscitation. When the strap structure 100 of the present invention is used, the base plate 1 is placed on the patient's back, and then the support leg 21 is rotated to fix the main unit 200 of the cardiopulmonary resuscitation machine in front of the person, and the fastener 22 is pulled to connect the fastener 22 with the main unit 200, wherein the snap-fitting engagement of the snap-fitting member 23 and the snap-fitting groove 21b ensures that the fastener 22 will not move freely, and the cardiopulmonary resuscitation machine can be started for pressing at this time.

[0040] The material of the bottom plate 1, the legs 21 and the fastener 22 has a certain hardness, and the material of the bottom plate 1, the legs 21 and the fastener 22 can be plastic, rubber or other materials harder than cloth. In this embodiment, the material of the bottom plate 1, the legs 21 and the fastener 22 is plastic.

[0041] It is understandable that a material with a certain hardness can ensure the pressing accuracy and avoid the problem of low pressing accuracy caused by a flexible material. The bottom plate 1 has a certain hardness. The bottom plate 1 can be placed under the patient's back and can also provide good support for the patient's back, preventing the patient from lying on uneven terrain and being easily injured in the process of being pressed. The clamping fit of the clamping member 23 and the clamping groove 21b ensures that the fastener 22 will not move freely, ensuring the safety and effectiveness of medical staff on patients when using the cardiopulmonary resuscitation machine.

[0042] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, there are two legs 21 , and the two legs 21 are rotatably connected to two ends of the base plate 1 , respectively, and each leg 21 is connected to a fastener 22 .

[0043] In the technical field of cardiopulmonary resuscitation, the cardiopulmonary resuscitation machine includes a main unit 200 and a strap structure 100 for connecting two opposite sides of the main unit 200. The main unit 200 is placed on the patient's chest to press the patient's chest. The strap structure 100 is connected to the main unit 200 to form a ring structure, which is used to place the patient's chest and back in the ring structure to fix the patient's back. In the technical solution of the present invention, two fasteners 22 can be respectively connected to the two opposite sides of the main unit 200 of the cardiopulmonary resuscitation machine.

[0044] In one embodiment of the present invention, Figure 4 and Figure 5 As shown, the multiple clamping grooves 21b on each of the mating side walls are serrated, which can facilitate the sliding in and out of the clamping member 23. In other embodiments, the multiple clamping grooves 21b on each of the mating side walls can also be wavy, which can facilitate the sliding in and out of the clamping member 23.

[0045] In one embodiment of the present invention, Figure 1 , Figure 2 and Figure 3 As shown, the leg device 2 further includes a first elastic member 24 , and two ends of the first elastic member 24 are respectively connected to the fastener 22 and the clamping member 23 , so that the clamping member 23 can be movably arranged on the fastener 22 .

[0046] It can be understood that the first elastic member 24 provides elastic force to the clamping member 23, so that the clamping member 23 can move relative to the fastener 22 on the one hand, and on the other hand, the elastic force provided by the first elastic member 24 can make the clamping member 23 inserted into the clamping groove 21b. When the fastener 22 moves under the action of an external force, the fastener 22 can drive the clamping member 23 to move, and the clamping member 23 slides along the groove wall of the clamping groove 21b and exits the current clamping groove 21b, and when it moves to another clamping groove 21b, it is inserted into another clamping groove 21b under the action of the first elastic member 24.

[0047] In this embodiment, the first elastic member 24 is a spring.

[0048] In one embodiment of the present invention, Figure 3 , Figure 6 and Figure 7As shown, the fastener 22 is provided with a fixed seat 221, and the fixed seat 221 and the fastener 22 are combined to form a limiting cavity 221a, and the clamping member 23 is movably inserted into the limiting cavity 221a; the two ends of the first elastic member 24 are respectively connected to the fixed seat and one end of the clamping member 23, and the other end of the clamping member 23 is provided with a clamping protrusion 232, and the clamping protrusion 232 is clamped and matched with the clamping groove 21b.

[0049] It is understandable that the fixing seat 221 can limit and position the clamping member 23, restricting the clamping member 23 to move only along the extension direction of the limiting cavity 221a, preventing the clamping member 23 from shaking and deflecting, ensuring the stability of the clamping member 23 and the clamping groove 21b, and thus improving the connection stability of the fastener 22 and the leg 21. At the same time, the shape of the clamping protrusion 232 is adapted to the shape of the clamping groove 21b, and the fixing seat 221 provides support for the first elastic member 24, and the first elastic member 24 provides a force on the clamping member 23 toward the matching side wall, so that the clamping protrusion 232 is inserted into or spit out of the clamping groove 21b.

[0050] In one embodiment, if Figure 3 and Figure 7 As shown, the clamping member 23 is provided with a mounting protrusion 231, the mounting protrusion 231 is spaced apart from the fixing seat 221, and the two ends of the first elastic member 24 are respectively connected to the mounting protrusion 231 and the fixing seat 221. The arrangement of the mounting protrusion 231 facilitates the installation of the first elastic member 24.

[0051] In one embodiment of the present invention, Figure 4 and Figure 5 As shown, the mating side wall is provided with a mating convex strip 211, and the side of the mating convex strip 211 away from the mating side wall is provided with the clamping groove 21b, and the mating convex strip 211 is spaced apart from the bottom wall of the accommodating cavity 21a, and the mating convex strip 211, the bottom wall of the accommodating cavity 21a and the mating side wall are enclosed to form a guide groove 21c; the two opposite side walls of the fastener 22 are respectively provided with guide plates 223, and the guide plates 223 are movably limited in the guide groove 21c. Through the provision of the guide groove 21c and the guide plate 223, the movement of the fastener 22 is guided and limited, so as to avoid shaking and deviation of the fastener 22 during the movement, and improve the connection stability between the fastener 22 and the leg 21.

[0052] In one embodiment of the present invention, Figure 3 As shown, the gap between the two groups of the clamping members 23 is defined as a self-locking gap 23a;

[0053] The leg device 2 also includes a locking member 25, which is disposed on the fastener 22 and movably penetrates the self-locking gap 23a. The locking member 25 can be moved close to or away from the clamping member 23 to lock or unlock the clamping member 23 and the leg 21.

[0054] It is understandable that after the fastener 22 is moved to the desired position, the clamping member 23 is inserted into the corresponding clamping groove 21b. At this time, the locking member can be inserted into the self-locking gap 23a, and the two groups of clamping members 23 are respectively abutted against the two sides of the locking member 25, which can achieve self-locking, so as to lock the clamping member 23, so that the clamping member 23 is clamped between the groove wall of the clamping groove 21b and the locking member 25, ensuring that the clamping member 23 will not move, and ensuring the position stability of the fastener 22. When the position of the fastener 22 needs to be adjusted, it is only necessary to pull the locking member 25 so that the locking member 25 is away from the clamping member 23, that is, unlock the clamping member 23, and the clamping member 23 can be inserted into or withdrawn from the clamping groove 21b driven by the fastener 22.

[0055] In one embodiment of the present invention, Figure 3 As shown, the leg support device 2 also includes a second elastic member 26, the two ends of which are respectively connected to the fastener 22 and the locking member 25, and the second elastic member 26 generates a force on the locking member 25 to insert the locking member 25 into the self-locking gap 23a.

[0056] It can be understood that the second elastic member 26 is used to stably insert the locking member 25 into the self-locking gap 23a, so as to ensure the stability of the locking of the locking member 23. In this embodiment, the second elastic member 26 is a spring.

[0057] In one embodiment of the present invention, Figure 1 , Figure 2 and Figure 3 As shown, a first operating plate 251 is provided at one end of the locking member 25 away from the connecting member 23, the first operating plate 251 extends toward the side of the locking member 25 away from the fastener 22, a second operating plate 222 is provided on the side of the fastener 22 facing the locking member 25, and the second elastic member 26 is arranged between the first operating plate 251 and the second operating plate 222; the end of the locking member 25 close to the connecting member 23 is wedge-shaped.

[0058] It is understandable that the first operating plate 251 and the second operating plate 222 can improve the point of force. When in use, the operator can pull the second operating plate 222 to drive the fastener 22 to move, and at the same time, the operator can pull the first operating plate 251 to drive the locking member 25 to exit the self-locking gap 23a. At this time, the clamping member 23 is unlocked, which can ensure that the fastener 22 can move smoothly. After the fastener 22 moves into place, let go, and the locking member 25 is inserted into the self-locking gap 23a under the action of the second elastic member 26, and the two groups of clamping members 23 are locked. At the same time, the end of the locking member 25 close to the clamping member 23 is wedge-shaped, which can ensure that the locking member 25 is smoothly inserted into the self-locking gap 23a.

[0059] In one embodiment of the present invention, Figure 1 , Figure 2 and Figure 8 As shown, the leg device 2 also includes a cover plate 27, which is detachably connected to the fastener 22 and encloses an installation cavity, and the clamping member 23 and the locking member 25 are respectively movably inserted into the installation cavity, and the first operating panel 251 is located outside the installation cavity.

[0060] It is understandable that, on one hand, the cover plate 27 can be provided to hide and protect the clamping member 23 or the locking member. The first operating panel 251 is located outside the installation cavity for easy operation.

[0061] In one embodiment of the present invention, Figure 1 , Figure 2 and Figure 8 As shown, the cover plate 27 is provided with an observation port 27a corresponding to the self-locking gap 23a.

[0062] It can be understood that by providing the observation port 27 a , it is possible to observe whether the locking member 25 locks the locking member 23 .

[0063] In one embodiment of the present invention, Figure 8 As shown, a limiting groove 27 b is provided on a side of the cover plate 27 facing the installation cavity, and the locking member 25 is limited in the limiting groove 27 b.

[0064] It can be understood that the limiting groove 27 b can guide and limit the movement of the locking member 25 , thereby preventing the locking member 25 from shaking or deflecting.

[0065] In one embodiment of the present invention, Figure 3 As shown, a side of the locking member 25 facing away from the fastener 22 is provided with an abutment plate 252, and a side of the abutment plate 252 away from the locking member 25 abuts against the cover plate 27. This can prevent the locking member 25 from shaking and deflecting.

[0066] The present invention also provides a cardiopulmonary resuscitation machine, such as Fig. 9 As shown, the cardiopulmonary resuscitation machine includes a host 200 and the above-mentioned strap structure 100. The specific structure of the strap structure 100 refers to the above-mentioned embodiment. Since the cardiopulmonary resuscitation machine adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here. Among them, the host 200 is arranged opposite to the bottom plate 1 of the strap structure, and the end of the strap fastener 22 away from the bottom plate 1 is connected to the host 200.

[0067] In one embodiment, if Fig. 9 As shown, hook members 210 are respectively provided on both sides of the cardiopulmonary resuscitation machine, and the fastener 22 is provided with a hanging hole. The hook member 210 is inserted into the hanging hole to realize the connection between the fastener 22 and the cardiopulmonary resuscitation machine, which is convenient to connect and simple to operate.

[0068] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made based on the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
