Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation assistive devices, in particular to a wrist rehabilitation assistive protector. Background Art

[0002] Wrist rehabilitation primarily focuses on improving wrist range of motion and strength, as well as developing finger grip and range of motion training for the finger and metacarpophalangeal joints. Wrist range of motion training includes wrist extension and flexion, forearm pronation and supination, and ulnar and radial deviations. It's also important to avoid excessive wrist flexion and passive flexion under unexpected forces to prevent secondary injury.

[0003] Therefore, wrist muscle strength training mainly focuses on wrist extensor muscle strength, wrist flexor muscle strength, and wrist radial deviation muscle strength. At the same time, wrist protection is also particularly important. The rehabilitation auxiliary brace in the existing technology focuses more on wrist training, and the protective effect on the wrist is relatively weak. In addition, the bending strength of the wrist will also vary slightly at different rehabilitation stages of the wrist. Generally, during the rehabilitation process, the wrist training intensity needs to be gradually increased to better match the rehabilitation needs of different stages. Therefore, in order to better assist wrist rehabilitation training and protect the wrist from excessive downward bending, it is necessary to design a wrist rehabilitation auxiliary brace.

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] See also Figure 1-4 , a wrist rehabilitation auxiliary support device, comprising:

[0035] A wrist clip 1, which is used to be put on the wrist;

[0036] A palm strap 2, which is used to be put on the palm;

[0037] a movable plate 3, which is arranged above the wrist clamp 1 and moves relative to the wrist clamp 1;

[0038] an elastic band 4 connected between the movable plate 3 and the palm strap 2; and

[0039] A position adjustment mechanism is provided on the wrist clamp 1 to support the movable plate 3 and drive the movable plate 3 to move relative to the wrist clamp 1;

[0040] The position adjustment mechanism drives the movable plate 3 to move so as to adjust the pulling strength of the elastic band 4 on the palm cover band 2 .

[0041] Specifically, during use, the wrist sleeve 1 is first placed on the wrist and positioned against the wrist. The palm sleeve 2 is then placed on the palm, with four fingers extended and only the thumb exposed. The palm sleeve 2 is then grasped by a grasping motion. The position adjustment mechanism then drives the movable plate 3 to move relative to the wrist sleeve 1, pulling one end of the elastic band 4 through the movable plate 3. After the elastic band 4 is tightened, the palm sleeve 2 is also tightened through the elastic band 4, so that the elastic band 4 is stretched between the wrist sleeve 1 and the palm sleeve 2. When the palm is bent downward, the elastic band 4 is stretched, accumulating elasticity. The length of the elastic band 4, pre-adjusted by the position adjustment mechanism, is thus adjusted to adjust the elastic force applied to the palm during subsequent bending, thereby achieving the effect of adjusting the intensity of the rehabilitation training. Simultaneously, the elastic force of the tightened elastic band 4 pulls the palm backward (without causing excessive backward bending), thereby preventing the wrist from accidentally bending downward excessively and causing secondary injury.

[0042] Furthermore, the wrist clip 1 includes a first curved splint 101 and a second curved splint 102. The first curved splint 101 and the second curved splint 102 are buckled together to form a clip shape that can be put on the wrist, and the first curved splint 101 and the second curved splint 102 are hinged with one side as the hinge side so that the first curved splint 101 and the second curved splint 102 can be rotated to open and close, which makes it convenient to wear. It only needs to be buckled on the arm near the wrist to be worn.

[0043] Furthermore, the other side of the first curved surface splint 101 and the second curved surface splint 102 is detachably connected by a buckle. After the first curved surface splint 101 and the second curved surface splint 102 are buckled together on the arm near the wrist, they are fixed by the buckle connection to maintain the state of being put on the arm. The buckle is a conventional connection form in the prior art, which can be a limited buckle form or a bandage form with a connecting clip to connect the first curved surface splint 101 and the second curved surface splint 102. In addition, to adapt to the wearing and use of arms of different thicknesses, it is allowed that after the first curved surface splint 101 and the second curved surface splint 102 are buckled together on the arm, although the first curved surface splint 101 and the second curved surface splint 102 are already closely attached to the arm, there is still a distance between the buckling parts. At this time, a bandage with a connecting clip (such as a belt with a hole buckle) is used to tighten the wrist splint 1 so that the wrist splint 1 is tightly wrapped around the arm and fixed.

[0044] Furthermore, the first curved splint 101 is located on the side of the wrist corresponding to the back of the hand, and the second curved splint 102 is located on the side of the wrist corresponding to the palm of the hand;

[0045] The movable plate 3 and the position adjustment mechanism are both arranged on the first arc-surface clamping plate 101 , so that the elastic band 4 is on the back of the hand to prevent the wrist from bending downward excessively.

[0046] Furthermore, the ends of the first curved splint 101 and the second curved splint 102 close to the wrist are both curved surfaces that bend outward, so that the curved surfaces can match the shape of the wrist where the palm width is greater than the arm width, so that they can fit the wrist, which is not only comfortable to wear but also provides a certain degree of protection.

[0047] Furthermore, the palm strap 2 is an annular nylon braided belt, which is a soft rope and will not cause damage to the palm when it is put on the palm.

[0048] Furthermore, the position adjustment mechanism includes:

[0049] A bearing 5, which is fixedly arranged on the outer surface of the wrist sleeve 1 through a bearing seat;

[0050] A bolt 6, one end of which is coaxially arranged inside the bearing 5 so as to rotatably support the bolt 6 through the bearing 5;

[0051] an arched fixed plate 7, which is fixedly connected to the movable plate 3 in an arched shape; and

[0052] The nut pair 8 is coaxially sleeved on the bolt 6 and threadedly engaged with the bolt 6. The nut pair 8 is located inside the arched fixing plate 7 and is fixedly connected to the arched fixing plate 7, that is, the nut pair 8 is fixed by the arched fixing plate 7 and allows the bolt 6 to pass through.

[0053] Specifically, during operation, the bolt 6, supported by the bearing 5, can rotate axially, thereby threadingly engaging with the nut pair 8. When the bolt 6 is stationary and the nut pair 8 is stationary and non-rotating relative to the movable plate 3 and the arched fixed plate 7, the threaded engagement process will drive the movable plate 3 to move relative to the wrist jacket 1, thereby achieving the effect of pulling the elastic band 4. The fixed bolt 6 and the nut pair 8 threadedly engaged with the bolt 6, connected to the arched fixed plate 7, also play a role in supporting the movable plate 3 on the outside of the wrist jacket 1.

[0054] To sum up, this device fixes the protector on the wrist through the wrist clip, and then puts the palm sleeve on the palm. The elastic tension of the elastic band keeps the palm and wrist in a relatively straight state, and the elastic tension of the elastic band can prevent the wrist from bending downward excessively due to accidental injury, thereby avoiding secondary injury. During the training process, the position adjustment mechanism adjusts the tension of the palm sleeve with the elastic band, so that different reverse forces can be adjusted during the downward bending of the palm, thereby providing different training intensities for different periods of wrist rehabilitation training, better realizing the auxiliary role of wrist rehabilitation, and having a certain protective effect on the wrist, so that the wrist rehabilitation period can be spent more safely.

[0055] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
