Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a brace for hand rehabilitation training. Background Art

[0002] In the field of modern medical rehabilitation, with the increasing demand for hand function restoration, rehabilitation equipment for hand dysfunction continues to develop and innovate. Hand dysfunction is often caused by trauma, surgical sequelae, neurological diseases, or muscle and joint degeneration. Patients may experience weakened hand muscle strength, decreased finger flexibility, and limited joint movement, seriously impacting their daily lives and work abilities.

[0003] Resistance-free rehabilitation training primarily relies on the patient's own strength to flex and extend the fingers or wrist. Without external resistance, it fails to exert sufficient load on the hand muscles. Consequently, it's difficult for patients to effectively strengthen their hand muscles during rehabilitation. Furthermore, existing hand rehabilitation training equipment is complex in design, difficult to operate, and lacks flexibility to adjust to individual patient needs. This can lead to discomfort and insecure fixation.

[0004] To this end, we propose a brace for hand rehabilitation training. Utility Model Content

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example: A brace for hand rehabilitation training, such as Figure 1-Figure 2As shown, it includes a brace sleeve portion 1 and a bending component 3. The brace sleeve portion 1 is used to be sleeved and fixed on the patient's hand, and the bending component 3 is used to assist in resistance rehabilitation training for the patient's hand. A through hole 6 is opened through one side of the brace sleeve portion 1. When the brace sleeve portion 1 is sleeved on the patient's hand, the patient's thumb extends outward through the through hole 6. A V-shaped connecting port 8 is opened from the bottom to the top at the lower side end of the brace sleeve portion 1. Two pull ears 9 are rotatably installed on the outer side surface of the brace sleeve portion 1. The two groups of pull ears 9 are distributed on both sides of the connecting port 8. A connecting ring is provided on the pull ear 9, and a strap 10 is provided on the connecting ring on the pull ear 9. The strap 10 is a prior art and will not be described here. Before use, loosen the strap 10 first. The brace sleeve portion 1 can adapt to wrists of different thicknesses through the opened connecting port 8. The provided strap 10 facilitates tightening and fixing the brace sleeve portion 1 on the patient's wrist.

[0028] Further, such as Figure 3 As shown, the upper end of the brace sleeve portion 1 is provided with a first bending connection 2, which includes a fixed ring 20 and a movable shaft 21. The fixed ring 20 is fixedly mounted on the upper end of the brace sleeve portion 1, and the movable shaft 21 is rotatably mounted inside the fixed ring 20. A bending assembly 3 is provided on the movable shaft 21, and the bending assembly 3 includes a first bending piece 300 and a second bending piece 301. The first bending piece 300 is fixedly mounted on the movable shaft 21, and a second bending connection piece 4 is provided between the first bending piece 300 and the second bending piece 301. The structure of the second bending connection piece 4 is the same as that of the first bending connection 2. When the second bending piece 301 is horizontally distributed on the extension line of the first bending piece 300, two groups of fan-shaped notches are formed between the first bending piece 300 and the second bending piece 301, and elastic splicing belts 42 are fixedly spliced ​​in the fan-shaped notches.

[0029] Furthermore, there are two groups of bending components 3, which are distributed on the left and right sides of the upper end of the brace sleeve part 1. A palm lining 5 is fixedly installed between the two groups of bending components 3. The patient's hand is set in the brace sleeve part 1, and the thumb extends outward through the through hole 6. At this time, the palm lining 5 covers the back of the patient's hand. A force ring 11 is fixedly set on the palm lining 5. The force ring 11 is set near the front end of the patient's fingers. When the patient makes a fist, the front end of the patient's fingers moves inward with the force ring 11. When the palm lining 5 is moved, the force ring 11 drives the palm lining 5 to bend. At this time, the palm lining 5 will rotate with the first bending connection 2 and the second bending connection 4. The elastic splicing belt 42 provided acts as a resistance, so that the patient needs to apply a certain force when making a fist. When the patient makes a fist, the second bending part 301 and the first bending part 300 are bent in sequence. When the patient relaxes his hand, the elastic force of the elastic splicing belt 42 will drive the patient's hand to unfold. This arrangement facilitates the patient to repeat hand rehabilitation training.

[0030] Further, such as Figure 4As shown, the inner wall surfaces of the brace sleeve portion 1 and the palm lining 5 are fixedly adhered with a breathable lining cotton 12. The breathable lining cotton 12 is in contact with the patient's hand skin to improve comfort. At the same time, the breathable lining cotton 12 has a sweat-absorbing effect, which prevents sweat accumulation in patients during hand rehabilitation training.

[0031] The working principle of this utility model:

[0032] The patient's hand is sleeved in the brace sleeve portion 1, and the thumb extends outward through the through-hole 6. At this time, the palm lining 5 covers the back of the patient's hand, and the force ring 11 is sleeved and distributed near the front end of the patient's fingers. When the patient makes a fist, the front end of the patient's fingers moves inward with the force ring 11, and the force ring 11 drives the palm lining 5 to bend. At this time, the palm lining 5 will rotate with the first bending connection 2 and the second bending connection 4. The elastic splicing belt 42 provided acts as a resistance, so that the patient needs to apply a certain force when making a fist. When making a fist, the patient bends the second bending part 301 and the first bending part 300 in sequence. When the patient's hand is relaxed, the elastic force of the elastic splicing belt 42 itself will drive the patient's hand to unfold. Through such a setting, it is convenient for the patient to repeat hand rehabilitation training.

[0033] Before use, first loosen the strap 10, and the brace sleeve part 1 can adapt to wrists of different thicknesses through the opened connection port 8. The provided strap 10 is convenient for tightening the brace sleeve part 1 and fixing it on the patient's wrist.
