[0044] As introduced in the background art, there is a problem of complex structure in the existing joint rehabilitation devices. To solve the above technical problems, the present invention proposes a joint motion injury rehabilitation device.

[0045] Embodiment 1

[0046] In a typical embodiment of the present invention, refer to Figure 1 and Figure 2As shown in the figure, a joint movement injury rehabilitation device can be used for the rehabilitation after joint movement injuries of the elbow joint or knee joint. It includes a device body 1, which is hollow inside. The device body 1 is provided with a joint stabilizing ring 4 to fix the bones at the joint. The first support frame 2 and the second support frame 3 are sleeved on the circumferential direction of the device body 1. One of the first support frame 2 and the second support frame 3 is placed on the upper side of the joint stabilizing ring 4, and the other is placed on the lower side of the joint stabilizing ring 4. One of the first support frame 2 and the second support frame 3 is placed on the front side of the leg or arm, and the other is placed on the back side of the leg or arm. The first support frame and the second support frame are connected by an angle limiter. The angle limiter 7 is used to limit the relative angle between the first support frame 2 and the second support frame 3, so that the joint can make flexion and extension movements of different angle sizes. The first support frame and / or the second support frame is provided with a fastening belt.

[0047] Among them, the device body 1 is a hollow cylindrical part, and both ends of the device body 1 are open. The device body is sleeved on the patient's leg or arm to protect the patient's leg or arm, and a breathable and comfortable composite fabric is used.

[0048] Reference Figure 2 As shown in the figure, an opening can be provided in the middle of one side of the device body 1, and the joint stabilizing ring 4 is installed at the opening of the device body 1. The joint stabilizing ring 4 includes a fixing ring 9, which protrudes from the device body 1. The outer side of the fixing ring 9 is oval, and an opening is provided in the middle of the fixing ring 9. The circumferential side of the fixing ring 9 is fixedly connected to the device body through a connecting piece 10. The connecting piece is an annular piece and is arranged on the outer ring of the fixing ring 9. Both the fixing ring 9 and the connecting piece 10 are made of rigid materials. The joint stabilizing ring 4 is arranged to fit the joint surface, and the joint stabilizing ring 4 fixes the bones at the joint in the correct position, reduces the wear on the meniscus, and prevents slipping.

[0049] In this embodiment, the first support frame 2 cooperates with the fastening belt so that the first support frame supports on the thigh or upper arm on the upper side of the patient's joint, and the second support frame 3 cooperates with the fastening belt so that the second support frame supports on the lower leg or forearm on the lower side of the patient's joint. Because the first support frame 2 and the second support frame 3 are sleeved on the outside of the device body, the distance between the first support frame 2 and the second support frame 3 is less than the length of the device body 1.

[0050] Considering that the first support frame 2 and the second support frame 3 need to fit the leg or arm, the first support frame 2 is a portal support frame, and the second support frame 3 is a portal support frame. The middle section of the first support frame 2 and the second support frame 3 is bent in an arc shape to fit the surface of the leg or arm. The first support frame is bent upward toward the upper side of the joint stabilizing ring, and the second support frame is bent backward toward the lower side of the joint stabilizing ring 4. In this way, the first support frame and the second support frame are arranged in reverse. After the device body 1 is sleeved on the patient's leg or arm and the first support frame 2 and the second support frame 3 are in place, the stability of the first support frame and the second support frame is ensured by the setting of the fastening belt.

[0051] To ensure the rationality of the structural setting, a spacing distance is set between the middle section of the first support frame 2 and the joint stabilizing ring 4, and both sides of the first support frame 2 are placed on both sides of the device body; correspondingly, a spacing distance is set between the middle section of the second support frame 3 and the joint stabilizing ring 4, and both sides of the second support frame 3 are placed on both sides of the device body 1.

[0052] It should be noted that although the first support frame 2 and the second support frame 3 are arranged in reverse, the structure of the second support frame 3 is the same as that of the first support frame 2 to facilitate the connection with the angle limiter 7; in some examples, considering that the first support frame 2 cooperates with the thigh or upper arm, and the second support frame cooperates with the calf or forearm, the bending angle of the middle section of the first support frame 2 is greater than the bending angle of the middle section of the second support frame 3.

[0053] Specifically, the first support frame 2 includes two layers of support bars 8. The support bars 8 are spaced apart and connected, which is beneficial to reducing the weight and facilitating the connection of the first support frame with the angle connector. The width of the inner support bar is greater than the width of the outer support bar, and the width of the support bar close to the device body 1 is greater than the width of the outer support bar. One limiting plate is placed on the outer side of the first support frame and the second support frame, and the other limiting plate is placed between the two layers of support bars.

[0054] It is easy to understand that the angle limiter 7 is hingedly connected to the support bars of the first support frame 2 and the second support frame 3 through a pin shaft 15. Refer to Figure 3 As shown, the angle limiter 7 includes two limiting plates 11. One limiting plate 11 is placed on the outer side of the outer support bar, and one limiting plate 11 is placed between two adjacent support bars. Limiting gears 12 are respectively arranged at the end parts of the support bars of the first support frame 2 and the second support frame 3 located between the two limiting plates 11. The two limiting gears 12 mesh with each other. The setting of the limiting gears 12 can transmit force when the first support frame or the second support frame rotates relative to the limiting plate, driving the second support frame or the first support frame to rotate relative to the limiting plate.

[0055] Refer to Figure 4 and Figure 5As shown in the figure, the limiting gear 12 is provided with an arc-shaped groove 13. A positioning shaft 14 is arranged on the inner side of the outer limiting plate. The positioning shaft 14 is located within the arc-shaped groove 13. When the side parts of the first support frame and the second support frame are in the same vertical plane, the upper positioning shaft is at the highest point of the arc-shaped groove, and the lower positioning shaft is at the lowest point of the arc-shaped groove. When the first support frame 2 or the second support frame 3 rotates relative to the angle limiter 7, the positioning shaft 14 moves along the arc-shaped groove 13, thereby adjusting the relative angle between the first support frame and the second support frame and limiting the maximum angle therebetween.

[0056] Among them, since the limiting gear 12 is arranged at the end of the outer support bar 8, the limiting gear 12 is selected as a bevel gear, as long as it can ensure the force transmission between the first support frame and the second support frame. The arc-shaped groove 13 in the limiting gear 12 is arranged on the upper side and the rear side of the pin shaft, and the teeth at the bevel gear are arranged on the upper side and the front side of the pin shaft. The two arc-shaped grooves in the two limiting gears are distributed in an eight-shaped structure.

[0057] In this embodiment, the fastening belt is an elastic band or a magic tape 5. The elastic band or the magic tape 5 is arranged at the middle section of the first support frame. Fixed rings are respectively arranged at both ends of the middle section of the inner support bar of the first support frame. The elastic band or the magic tape passes through the fixed rings on both sides; the elastic band or the magic tape can be adjusted according to the patient's body type to meet the needs of different people. This design enables the device to be flexibly fixed on the joints of different individuals.

[0058] An anti-slip member 6 is arranged on the opposite side of the middle section of the second support frame. The anti-slip member 6 can be an anti-slip silica gel pad. Fixed rings are respectively arranged on the side of the middle section of the inner support bar of the anti-slip member and the second support frame. The anti-slip rubber pad is connected to the fixed ring. The arrangement of the anti-slip member prevents the first support frame and the second support frame from slipping relative to the device body.

[0059] The rehabilitation device provided in this embodiment includes two parts. One part is the device body sleeved on the leg or the arm, and the other part is the first support frame and the second support frame which are oppositely arranged and reversely arranged. With the arrangement of the fastening belt, the connection of the first support frame and the second support frame can not only be stably fixed on the upper and lower sides of the joint and cover the front and rear sides of the joint, but also has a simple overall structure, is convenient for the patient to quickly wear, is easy to operate, and can ensure the setting stability of the outer structural members of the device body. The angle between the two support frames is limited by the angle limiter, and the bending angle of the knee can be limited, which is crucial for controlling the movement range of the joint and assisting in rehabilitation training. The rehabilitation device can not only assist in the rehabilitation of the joint, but also help the patient gradually restore the normal movement ability of the joint.

[0060] Embodiment Two

[0061] This embodiment provides a working method of a joint movement injury rehabilitation device, including the following content:

[0062] Put one set of the device body on a person's leg or arm, place the shaft joint or knee joint at the joint stabilizing ring 4 to fix the bone at the joint such as the patella, and provide necessary stability for the joint;

[0063] Connect the first support frame and the second support frame through the angle limiter 7;

[0064] Put the first support frame 2 and the second support frame 3 on the outside of the device body 1. One of the first support frame and the second support frame is placed on the upper side of the joint stabilizing ring, and the other is placed on the lower side of the joint stabilizing ring. One of the first support frame and the second support frame is placed on the front side of the leg or arm, and the other is placed on the back side of the leg or arm, playing a role in supporting the joint, providing additional stability and support for the joint, and then fastening through the magic tape. The device can be firmly fixed on the thigh or arm position. According to the body type differences of patients, the design of the magic tape allows for pressure adjustment to adapt to legs or arms of different thicknesses, ensuring that the rehabilitation device is both tight and comfortable. The setting of the anti-slip part at the second support frame helps prevent the rehabilitation device from slipping during activities, ensuring that the rehabilitation device always remains in the appropriate position;

[0065] For the knee joint, bend the bone at the joint to help the patient assist in the rehabilitation of the joint, and the relative angle between the first support frame and the second support frame is limited by the limitation of the angle limiter.

[0066] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications.
