Description

Technical Field

[0001] This utility model relates to the field of wheelchair technology, specifically to an anti-spasticity device for hemiplegic patients using a wheelchair. Background Technology

[0002] Hemiplegic patients often experience spastic patterns due to abnormal muscle tone, which affects the rehabilitation process. In current technology, anti-spasticity postural management is mostly limited to mattresses or independent braces, lacking integrated solutions for wheelchair environments. Prolonged sitting in a wheelchair can easily induce abnormal postures, such as shoulder subluxation, hip adduction, and foot drop.

[0003] For example, a wheelchair for hemiplegic patients with a support plate is described in patent CN216985445U. The wheelchair includes a wheelchair body and a lifting mechanism. Armrests are provided on both sides of the wheelchair body, and support plates are provided on the outer sides of the armrests. The wheelchair is equipped with a base plate and a baffle. The base plate and armrests support the arms of the hemiplegic patient, and the baffles prevent the arms of the hemiplegic patient from slipping out of the wheelchair. However, it only prevents the arms of the hemiplegic patient, but does not restrain them to a certain extent. This causes the shoulder joint to adduct and the elbow to flex. At the same time, it does not fix the torso of the hemiplegic patient, causing the torso of the patient sitting in the wheelchair to exhibit abnormal compensatory postures, which reduces the practicality of the device.

[0004] Based on this, we now offer an anti-spasticity device for wheelchair-bound hemiplegic patients, which can eliminate the drawbacks of existing devices. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-5As shown, the anti-spasticity device for hemiplegic patients in a wheelchair includes a chair body 1. Handles 11 are symmetrically rotatably connected to the outer wall of the chair body 1. A backrest 12 is fixedly connected to the outer wall of the handle 11. A strap 13 is fixedly connected to the outer wall of the handle 11. A side plate 14 is slidably connected to the inner wall of the handle 11. A fixing bolt 15 is threadedly connected to the inner wall of the side plate 14. The outer wall of the fixing bolt 15 penetrates the outer wall of the handle 11. A foot pedal assembly 2 is provided at the bottom of the chair body 1. An adjustment mechanism 3 is provided on the outer wall of the chair body 1. An armrest assembly 4 is symmetrically provided at the top of the chair body 1.

[0027] In this embodiment, the angle between the chair body 1 and the backrest 12 can be adjusted by the adjustment mechanism 3. Then, the patient sitting in the wheelchair can be fixed by the straps 13. The foot pedal assembly 2 can place the patient's feet in a suitable position. Then, the armrest assembly 4 can position and restrict the patient's arms to prevent adduction of the shoulder joint and flexion of the elbow.

[0028] In an optional embodiment, such as Figure 2 and Figure 3 As shown, the foot pedal assembly 2 includes a rotating rod 21. The outer wall of the rotating rod 21 is rotatably connected to the inner wall of the chair body 1. A connecting arm 22 is symmetrically fixedly connected to the outer wall of the rotating rod 21. A foot pedal 23 is fixedly connected to the connecting arm 22 away from the outer wall of the chair body 1. A first spring 24 is fixedly connected to the inner wall of the rotating rod 21. A sliding plate 25 is fixedly connected to the end of the first spring 24. The outer wall of the sliding plate 25 is slidably connected to the inner wall of the rotating rod 21. A connecting rod 26 is fixedly connected to the end of the sliding plate 25. The outer wall of the connecting rod 26 is slidably connected to the inner wall of the rotating rod 21. A limit block 27 is fixedly connected to the end of the connecting rod 26 away from the connecting arm 22. Pulling the limiting block 27 moves the connecting rod 26 and the sliding plate 25, stretching the first spring 24 and causing the cylindrical protrusion on the outer wall of the limiting block 27 to no longer engage with the inner wall of the chair body 1. Then, the connecting arm 22 can be rotated to rotate the foot pedal 23 synchronously, thereby changing the position of the foot pedal 23. When it reaches the appropriate position, stop rotating and release the limiting block 27. At this time, under the action of the first spring 24, the outer wall of the cylindrical protrusion engages with the inner wall of the chair body 1, thereby preventing the rotating rod 21 from rotating and keeping the foot pedal 23 in this position so that it can not move, making it convenient for the patient to place their foot on the foot pedal 23.

[0029] In an optional embodiment, such as Figure 2 and Figure 3 As shown, cylindrical protrusions are evenly distributed on the outer wall of the seat body 1 near the limiting block 27, and the outer wall of the cylindrical protrusions is inserted into the inner wall of the seat body 1. Through the connection between the cylindrical protrusions and the seat body 1, the rotation of the rotating rod 21 can be restricted, thereby limiting the position of the foot pedal 23.

[0030] In an optional embodiment, such as Figure 2 and Figure 3 As shown, the slide plate 25 is rectangular in shape, and the inner wall of the rotating rod 21 has a groove that matches the shape of the slide plate 25. The slide plate 25 restricts the connecting rod 26, so that when the rotating rod 21 rotates, it drives the slide plate 25 and the connecting rod 26 to rotate synchronously.

[0031] In an optional embodiment, such as Figure 2 and Figure 4 As shown, the adjustment mechanism 3 includes a mounting bracket 31. The outer wall of the mounting bracket 31 is fixedly connected to the outer wall of the chair body 1. A threaded rod 32 is threadedly connected to the inner wall of the mounting bracket 31. A retaining tooth 33 is rotatably connected to the end of the threaded rod 32. The outer wall of the retaining tooth 33 is slidably connected to the inner wall of the chair body 1. A gear 34 is engaged with the teeth of the retaining tooth 33. A rotating shaft 35 is fixedly connected to the axis of the gear 34. The outer wall of the rotating shaft 35 is rotatably connected to the inner wall of the chair body 1. The outer wall of the rotating shaft 35 is also rotatably connected to the handle 11. The bottom is fixedly connected. By rotating the threaded rod 32, the threaded rod 32 moves on the inner wall of the mounting bracket 31, causing the locking teeth 33 to move synchronously. This prevents the teeth on the outer wall of the locking teeth 33 from contacting the teeth on the outer wall of the gear 34. Then, the tilt of the chair back 12 can be adjusted. After adjusting to the appropriate angle, the threaded rod 32 is screwed back, so that the teeth on the outer wall of the locking teeth 33 contact the teeth on the outer wall of the gear 34. This restricts the gear 34 and the rotating shaft 35, preventing the rotating shaft 35 from rotating.

[0032] In an optional embodiment, such as Figure 2 and Figure 4 As shown, the tooth 33 has an arc shape to facilitate engagement between the tooth 33 and the gear 34.

[0033] In an optional embodiment, such as Figures 1-5 As shown, the armrest assembly 4 includes a fixing plate 41. The outer wall of the fixing plate 41 is fixedly connected to the top of the chair body 1. A support plate 42 is slidably connected to the inner wall of the fixing plate 41. A fixing strap 43 is fixedly connected to the top of the support plate 42. A finger sleeve 44 is fixedly connected to the top of the support plate 42 near the top of the fixing strap 43. A baffle 45 is fixedly connected to the top of the support plate 42. The patient's forearm is placed on the support plate 42, and the patient's fingers are inserted into the finger sleeve 44. Then, the patient's wrist and forearm are fixed by the fixing strap 43 to prevent the patient's shoulder joint from adduction and elbow flexion.

[0034] In an optional embodiment, such as Figures 1-5As shown, a limiting rod 46 is inserted into the inner wall of the fixed plate 41, and the outer wall of the limiting rod 46 is inserted into the inner wall of the support plate 42. A second spring 47 is sleeved on the outer wall of the limiting rod 46. One end of the second spring 47 is fixedly connected to the outer wall of the fixed plate 41, and the other end is fixedly connected to the outer wall of the limiting rod 46. By pulling the limiting rod 46, the second spring 47 is stretched, so that the outer wall of the limiting rod 46 is no longer inserted into the inner wall of the support plate 42. Then the baffle 45 can be pulled to move the support plate 42 synchronously, so that the support plate 42 extends. When the extension distance is sufficient, the limiting rod 46 is released. Under the action of the second spring 47, the outer wall of the limiting rod 46 is inserted into the inner wall of the support plate 42 again.

[0035] The above embodiments disclose an anti-spasticity device for hemiplegic patients in wheelchairs. First, the angle between the backrest 12 and the seat 1 is adjusted according to the patient's needs. By rotating the threaded rod 32, it moves along the inner wall of the mounting frame 31, causing the locking teeth 33 to move synchronously. This prevents the teeth on the outer wall of the locking teeth 33 from contacting the teeth on the outer wall of the gear 34. Then, the tilt of the backrest 12 can be adjusted. Once the appropriate angle is reached, the threaded rod 32 is screwed back on, causing the teeth on the outer wall of the locking teeth 33 to contact the teeth on the outer wall of the gear 34. This restricts the gear 34 and the rotating shaft 35, preventing the shaft 35 from rotating. The hemiplegic patient can then sit in the wheelchair and be secured by straps. The patient's torso is restrained by strap 13, and then the torso is further restricted by side panels 14 to prevent abnormal compensatory postures. Then, based on the patient's leg condition, the position of the foot pedal 23 is adjusted, and the limiting block 27 is pulled, causing the connecting rod 26 and the sliding plate 25 to move. This stretches the first spring 24, causing the cylindrical protrusion on the outer wall of the limiting block 27 to no longer engage with the inner wall of the chair body 1. The connecting arm 22 can then be rotated, causing the foot pedal 23 to rotate synchronously, thus changing its position. Once the foot pedal 23 is in the appropriate position, rotation stops, and the limiting block 27 is released. At this point, under the action of the first spring 24, the cylindrical protrusion... The outer wall is inserted into the inner wall of the chair body 1, preventing the rotating rod 21 from rotating further and keeping the foot pedal 23 in this position, making it convenient for the patient to place their feet on the foot pedal 23. Then, the patient's forearm is placed on the support plate 42, and their fingers are inserted into the finger sleeves 44. The wrist and forearm are then secured with fixing straps 43 to prevent shoulder adduction and elbow flexion. Before the patient places their arm on the support plate 42, the distance between the support plate 42 and the patient can be adjusted according to their individual needs. By pulling the limiting rod 46, the second spring 47 is stretched, preventing the outer wall of the limiting rod 46 from contacting the support plate 42. After the inner wall is inserted, the baffle 45 can be pulled, which will move the support plate 42 synchronously and extend the support plate 42. When the extension distance is sufficient, the limiting rod 46 is released. Under the action of the second spring 47, the outer wall of the limiting rod 46 is inserted into the inner wall of the support plate 42 again. In summary, the angle between the chair body 1 and the backrest 12 can be adjusted by the adjustment mechanism 3. Then, the patient sitting in the wheelchair can be fixed by the strap 13. The foot pedal assembly 2 can place the patient's feet in a suitable position. Then, the armrest assembly 4 can position and restrict the patient's arms to prevent adduction of the shoulder joint and flexion of the elbow.

[0036] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
