Technical Field

[0001] This utility model relates to the field of rehabilitation training equipment technology, and in particular to a finger joint trainer for rehabilitation. Background Technology

[0002] Finger joint injuries or diseases are quite common, especially for stroke patients. Hand dysfunction is one of the common sequelae of stroke, seriously affecting their ability to live independently and their quality of life. During the rehabilitation process, stroke patients urgently need effective finger joint training to restore finger mobility, flexibility, and muscle strength.

[0003] Currently, most finger joint trainers on the market use a direct-fit finger sleeve design, which poses hidden safety hazards in actual use. During long-term training, stroke patients often experience sensory function decline due to nerve damage in their hands. In this case, after the spring inside the trainer is released under force, it will reset quickly due to the lack of effective resistance control for stroke patients. The resulting impact force can easily compress or pull on the fragile finger joints, tendons, and other tissues of stroke patients, leading to secondary injuries such as joint dislocation and soft tissue contusion, seriously affecting the safety and effectiveness of rehabilitation training. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where stroke patients have difficulty controlling the speed of spring rebound due to weakened hand strength, leading to hand injuries. Therefore, this invention proposes a rehabilitation finger joint trainer.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0040] Reference Figures 1-5A rehabilitation finger joint trainer includes a wrist support 1, on which a wrist strap 2 is installed. There are two wrist straps 2, one end of which is fixedly connected to the wrist support 1. The inner surface of the wrist strap 2 is provided with a Velcro felt surface, and the outer surface of the wrist strap 2 is provided with a Velcro adhesive surface. The two wrist straps 2 are glued together.

[0041] A fixing block 3 is symmetrically fixedly connected to the top surface of the wrist support 1. A rotating rod 4 is rotatably connected to the fixing block 3. An adjusting frame 5 is fixedly connected to the rotating rod 4. A horizontal plate 6 is fixedly connected to the end of the adjusting frame 5 away from the rotating rod 4. Multiple first springs 7 are fixedly connected to the bottom surface of the horizontal plate 6. A first finger sleeve 8 is installed on the end of each of the multiple first springs 7 away from the horizontal plate 6. A screw 9 is rotatably connected to the top surface of the wrist support 1. A nut 91 is threadedly connected to the screw 9. A crank 10 is rotatably connected to the screw 9. A second spring 11 is fixedly connected to the end of the crank 10 away from the screw 9. A second finger sleeve 12 is installed on the end of the second spring 11 away from the crank 10.

[0042] A rehabilitation finger joint trainer also includes an adjustment component and a protective component, the adjustment component being used to adjust the angle of the adjustment frame 5;

[0043] The adjustment assembly includes a retaining bar 41, a sliding sleeve 42, a sliding groove 43, a stop block 44, and a limiting groove 45. The retaining bar 41 is symmetrically fixedly connected to the front end of the rotating rod 4. The sliding sleeve 42 is slidably connected to the rotating rod 4. The sliding groove 43 is opened on the sliding sleeve 42. The retaining bar 41 is slidably connected to the sliding groove 43. The stop block 44 is symmetrically fixedly connected to the sliding groove 43. The limiting groove 45 is symmetrically opened on the fixed block 3. The stop block 44 is slidably connected to the limiting groove 45. The diameter of the limiting groove 45 is slightly larger than the diameter of the stop block 44, and the thickness of the stop block 44 is greater than the thickness of the limiting groove 45. This allows the end of the stop block 44 to slide to the inner wall of the limiting groove 45, preventing the stop block 44 from rotating inside the limiting groove 45. At the same time, the front end of the stop block 44 is continuously in contact with the retaining bar 41, thereby preventing the stroke patient from rotating the adjustment frame 5 through the first spring 7 during training.

[0044] The protective assembly is used to protect fingers from injury. The protective assembly includes a support shaft 61, a knob 62, a threaded rod 63, a protective plate 64, and a through hole 65. The support shaft 61 is fixedly connected to the top surface of the horizontal plate 6. The knob 62 is rotatably connected to the top surface of the support shaft 61. The threaded rod 63 is threadedly connected to the middle of the knob 62. The protective plate 64 is fixedly connected to the bottom surface of the threaded rod 63. The bottom of the protective plate 64 is provided with a protective pad made of soft, skin-friendly material, which can better conform to the shape of the finger. When the hand strength of the stroke patient is weakened, the protective plate 64 can absorb the impact force generated by the reset of the first spring 7, preventing it from directly acting on the stroke patient's finger and avoiding pain caused by the impact force.

[0045] Through holes 65 are spaced on the top surface of the protective plate 64. The number of through holes 65 corresponds to the number of first springs 7. The diameter of the through holes 65 is larger than that of the first springs 7, leaving sufficient space for the deformation of the first springs 7. During the process of flexing and extending the fingers, the first springs 7 can be freely compressed and stretched without being restricted by the protective plate 64, ensuring that the training movements are smooth and natural.

[0046] The functional principle of this utility model can be explained through the following operation methods:

[0047] First, stroke patients secure the wristband 2 to their wrists using Velcro. The tightness can be adjusted according to the size of their wrists to ensure the trainer is worn stably.

[0048] When the overall training intensity needs to be adjusted, the stop 44 is disengaged from the limiting groove 45 by sliding the sleeve 42 on the sliding rod 4. At this time, rotating the sleeve 42 will synchronously drive the rotating rod 4 to rotate through the locking strip 41, and the externally fixed adjustment frame 5 will rotate accordingly. Stroke patients can adjust the intensity of multiple first finger sleeves 8 according to their own hand strength. When the second finger sleeve 12 needs to be adjusted, the nut 91 is rotated to release the nut 91 from the limiting position on the screw top. At this time, rotating the crank 10 will cause the second spring 11 on the outside to stretch along the crank 10, thereby adjusting the intensity of the thumb. After the adjustment is completed, the nut 91 is rotated again to fix the crank 10 on the threaded rod 63 to prevent the crank 10 from slipping during training.

[0049] When the position of the protective plate 64 needs to be adjusted, the knob 62 is turned so that it rotates on the support shaft 61. The threaded rod 63 inside then engages with the thread inside the knob 62 and moves within the knob 62, thereby adjusting the position of the protective plate 64 at the bottom. This prevents the impact force generated by the reset of the first spring 7 after the hand strength of the stroke patient has weakened, which could pull on the finger and cause injury.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
