Description

Technical Field

[0001] This utility model relates to the field of hand function exercise and care support for rheumatoid arthritis patients, and in particular to a wearable hand function exercise and care support for rheumatoid arthritis patients. Background Technology

[0002] Rheumatoid arthritis patients' hand joints are prone to inflammation, resulting in swelling, pain, and deformity. They need to maintain joint function and assist in exercise through long-term care braces. In current clinical and daily care, hand care braces are an important tool for protecting and restoring the function of patients' hands. They are widely used in joint fixation during acute flare-ups, functional exercises during remission, and deformity prevention.

[0003] When using the existing one, place your hand naturally on the palm and finger support unit, so that your wrist fits against the wrist rest and your fingers correspond to the finger rest. Then pull the Velcro adjustment straps on the wrist and palm to adjust until your hand is not tight or compressed and the support is stable and does not slip. It can be worn all day without affecting activities such as eating and turning pages. When exercising, add an elastic element to the support interface and slowly perform finger flexion and extension movements when you have free time.

[0004] Existing wearable hand function training braces for rheumatoid arthritis patients typically use springs as resistance components to assist finger exercises. However, the force of these springs is usually a preset fixed value, which cannot be adjusted individually according to the actual recovery progress of each finger. This results in all fingers bearing the same force during exercise, making it difficult to adapt to the differences in the recovery progress of different fingers, affecting the targeted nature and effectiveness of the exercise. At the same time, existing braces have significant shortcomings in terms of operation and fixation stability. Patients often need to go through cumbersome steps to complete the wearing and adjustment process, which is especially inconvenient for rheumatoid arthritis patients whose hand flexibility is already limited. Moreover, the fixation effect of the brace after wearing is unstable, and it is easy to shift or loosen during daily activities. This not only fails to provide stable support for the hand joints, but may also affect the standardization of exercise movements. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a wearable hand function exercise and care bracket for rheumatoid arthritis patients, aiming to improve the problems of existing technologies where the spring resistance cannot be adjusted individually according to the recovery degree of a single finger, the operation is cumbersome, and the wearing and fixing are unstable.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wearable hand function exercise and care bracket for rheumatoid arthritis patients, comprising a wrist brace, a diverter block fixedly connected to the top outer wall of the wrist brace, an inflation tube fixedly connected to the inner wall of the diverter block, a first finger tube fixedly connected to the end of the inflation tube, a slot provided on the top outer wall of the first finger tube, a support ring fixedly connected to the outer wall of the first finger tube, a connecting block rotatably connected to the outer wall of the first finger tube via a pivot, a second finger tube rotatably connected to the connecting block via a pivot, a slot fixedly connected to the top outer wall of the second finger tube, a buckle engaged on the inner wall of the slot, an elastic band fixedly connected to the outer wall of the buckle, and a plug fixedly connected to the end of the elastic band.

[0007] As a further description of the above technical solution: An inflatable ball is fixedly connected to the end of the inflation tube, and an airbag is fixedly connected to the end of the inflation tube.

[0008] As a further description of the above technical solution: The inflation tubes are provided in several groups, and the outer walls of the several groups of inflation tubes are fixedly connected to connecting brackets.

[0009] As a further description of the above technical solution: The slot is angled, and the edges of the slot are chamfered.

[0010] As a further description of the above technical solution: The plug is configured in a hook shape and is inserted into the inner wall of the slot.

[0011] As a further description of the above technical solution: A rubber pad is fixedly connected to the outer wall of the second finger cylinder on the side away from the first finger cylinder.

[0012] As a further description of the above technical solution: The outer wall of the support ring near the second finger cylinder is adapted to its outer wall, and a groove is provided on the top outer wall.

[0013] As a further description of the above technical solution: The slots are provided in several groups, and the several groups of slots are arranged in a straight line according to the central axis of the first finger cylinder.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the combination of the wrist guard plate with the first and second finger tubes can fully cover the patient's palm and fingers, effectively isolating them from external impacts to protect damaged joints; the support ring can support and limit the fingers with insufficient strength, preventing reverse bending during exercise or daily activities; at the same time, the multiple sets of inclined slots on the first finger tube, in conjunction with the hook-shaped plugs, allow the patient to select different slots to insert elastic bands according to the actual recovery progress of each finger, adapting to the differences in the recovery progress of the fingers.

[0015] 2. In this utility model, by setting an airbag, the expansion degree can be adjusted by inflating the airbag. This can fill the gap between the support and the fingers, enhance the fit of the support after wearing, prevent the support from shifting during daily activities, and ensure support stability. When the hand is subjected to force or slight collision, the elastic deformation of the airbag can absorb the impact force, reduce the direct stimulation to the joints, and thus reduce the discomfort and pain of the patient during use.

The first finger tube 4 and the second finger tube 6 are rotated together by the connecting block 15 and the rotating shaft, and can move synchronously with the flexion and extension of the fingers, conforming to the natural movement trajectory of the hand. The top outer wall of the first finger tube 4 is provided with a slot 11. The slot 11 is set in an inclined shape and the edge is chamfered, which can reduce the difficulty of insertion and removal and avoid scratching the fingers. At the same time, there are several sets of slots 11, which are arranged in a straight line according to the central axis of the first finger tube 4, and can be used with the plug 10 to realize the tension adjustment of the elastic band 9. The slot 11 is set in an inclined shape, the edge of the slot 11 is chamfered, and there are several sets of slots 11, which are arranged in a straight line according to the central axis of the first finger tube 4.

[0021] Reference Figures 2-4 A support ring 5 is fixedly connected to the outer wall of the first finger cylinder 4. The outer wall of the support ring 5 near the second finger cylinder 6 is adapted to its outer wall and has a groove on its top outer wall. This groove can bend and guide the elastic band 9 to prevent the elastic band 9 from shifting. At the same time, the support ring 5 can limit the second finger cylinder 6 when the finger is bent to prevent the finger from bending backward due to weakness or excessive force. The outer wall of the support ring 5 near the second finger cylinder 6 is adapted to its outer wall and has a groove on its top outer wall. The outer wall of the first finger cylinder 4 is rotatably connected to a connecting block 15 through a pivot. The connecting block 15 provides an installation base for the pivot, realizing the rotatable connection between the first finger cylinder 4 and the second finger cylinder 6. The connecting block 15 is also rotatably connected to the second finger cylinder 6 through a pivot. A rubber pad 13 is fixedly connected to the outer wall of the second finger cylinder 6 away from the first finger cylinder 4. The rubber pad 13 can reduce the direct friction between the finger cylinder and the fingertip and improve the comfort of wearing for a long time. The outer wall of the second finger cylinder 6 away from the first finger cylinder 4 is fixedly connected to a rubber pad 13.

[0022] Reference Figure 1 , Figures 3-4 The top outer wall of the second finger cylinder 6 is fixedly connected to a slot 7. The slot 7 and the buckle 8 are connected by a snap-fit ​​method, which facilitates the quick disassembly and replacement of the elastic band 9. The inner wall of the slot 7 is snapped with a buckle 8. The buckle 8 is used to connect the slot 7 and the elastic band 9 to achieve stable fixation of the elastic band 9. The outer wall of the buckle 8 is fixedly connected to the elastic band 9. The elastic band 9 can provide resistance for finger exercise through its own elasticity. The end of the elastic band 9 is fixedly connected to a plug 10. The plug 10 is set in a hook shape and is adapted to the slot 11. It can be stably inserted into different slots 11 and the tension of the elastic band 9 can be adjusted with the slot 11. The plug 10 is set in a hook shape and is inserted into the inner wall of the slot 11. Reference Figure 3 , Figure 5 An inflation tube 2 is fixedly connected to an inflation ball 14 at its end. The inflation ball 14 can generate air pressure by manual pressing. The air pressure is transmitted to the air bladder 12 through the inflation tube 2, providing power for the inflation of the air bladder 12. The air bladder 12 is fixedly connected to the end of the inflation tube 2. After inflation, the air bladder 12 can fit tightly against the inner wall of the finger, filling the gap between the support and the finger to enhance the wearing stability. At the same time, its softness can buffer external impact and reduce joint pressure. Several sets of inflation tubes 2 are provided. Connecting brackets 3 are fixedly connected to the outer wall of several sets of inflation tubes 2. The connecting brackets 3 can connect the scattered inflation tubes 2 into a whole, improve the integrity of the pipeline structure, avoid displacement or breakage of the inflation tubes 2 due to movement, and ensure the stability of gas delivery.

[0023] Working principle: First, the wrist brace 1 serves as the basic load-bearing component, stably supporting the palm and wrist. The diverter block 16 at its top, through its inner wall fixing structure, neatly distributes multiple sets of inflation tubes 2 according to the finger distribution direction, ensuring orderly tubing without affecting usability. One end of each inflation tube 2 connects to the diverter block 16, and the other end connects to the first finger cylinder 4, both fixing the position of the first finger cylinder 4 and providing a gas delivery channel for the subsequent inflation of the air bladder 12. After the patient places their fingers into the first finger cylinder 4 and the second finger cylinder 6, the first finger cylinder 4 and the second finger cylinder 6, through the rotational cooperation formed by the connecting block 15 and the rotating shaft, can move synchronously with the flexion and extension of the fingers, conforming to the natural movement trajectory of the hand. At this time, pressing the inflation ball 14 transmits air pressure through the inflation tubes 2 to the air bladder 12. After the air bladder 12 inflates, it fits tightly against the inner wall of the finger, filling the gap between the support and the finger, enhancing wearing stability, and simultaneously buffering external impact to protect the joints. The connecting bracket 3 on the outer wall of the multiple sets of inflation tubes 2 connects the tubing into a whole. To prevent pipe displacement or breakage during activity and ensure stable gas delivery, the elastic band 9 is secured to the slot 7 at the top of the second finger cylinder 6 via the buckle 8 during hand exercises. The hook-shaped plug 10 at the end of the elastic band 9 is inserted into the slot 11 at the top of the first finger cylinder 4. The elasticity of the elastic band 9 provides resistance for finger exercises. The support ring 5 on the outer wall of the first finger cylinder 4 limits the second finger cylinder 6 when the finger is bent, preventing the finger from bending backward due to weakness or excessive force. On the other hand, the slot at its top bends and guides the elastic band 9, preventing it from shifting. The inclined design, chamfered edges, and multiple straight-line arrangement of the slot 11 reduce the difficulty of inserting and removing the plug 10, prevent scratching the finger, and allow the tension of the elastic band 9 to be adjusted by selecting different slots 11 to suit the exercise needs of different finger recovery levels. The rubber pad 13 at the end of the second finger cylinder 6 reduces friction between the finger cylinder and the fingertip, improving comfort during long-term wear.
