Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a hand rehabilitation training device. Background Technology

[0002] Rehabilitation training refers to the process of helping patients recover or improve physiological functional impairments caused by disease, injury, or surgery through scientific and systematic exercise therapy and functional exercises. Its core goal is to improve an individual's physical function, self-care ability, and social participation. It covers muscle strength training, joint range of motion recovery, balance and coordination exercises, and cardiopulmonary function enhancement. Usually, a team of rehabilitation physicians and therapists develops a personalized plan based on the assessment results and implements it step by step with the help of equipment, manual techniques, or technical means, ultimately enabling patients to return to a healthy state or adapt to life with disabilities.

[0003] A search revealed that CN219896060U discloses a hand rehabilitation training device that addresses the problem that "hand muscles are often confined within a fixed plate for extended periods, preventing movement and leading to muscle cramps or damage, which hinders normal hand recovery." The device uses a rubber plate that massages the patient's muscles with a massage ball when pressed, and a retracting rod that contracts into a fixed column to relax and massage the arm muscles. However, the device's structure is relatively simple and lacks the ability to adjust training intensity as needed. This makes it unsuitable for addressing the different muscle strength training requirements of various patients. Furthermore, excessively high training intensity could cause secondary injury to the patient's hand. Therefore, improvements are needed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a hand rehabilitation training device with the advantage of adjusting the intensity of muscle strength training.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hand rehabilitation training device, comprising a shell, a wrist rest fixedly connected to the front of the shell, a fixed seat located in the inner cavity of the wrist rest fixedly connected to the front of the shell, a small motor fixedly connected inside the fixed seat, a rotating shaft fixedly sleeved at the other end of the output shaft of the small motor, a rotating rod fixedly sleeved at the other end of the rotating shaft, a sleeve rod movably connected to the outer surface of the rotating rod, a round rod fixedly connected to the right side of the sleeve rod, the other end of the round rod penetrating the shell and extending into the inner cavity of the shell and movably sleeved with a fixed frame, a movable plate fixedly connected to the right end of the round rod, and the outer surface of the movable plate movably connected to the inner surface of the fixed frame.

[0006] As a preferred embodiment of this utility model, the inner surface of the outer shell is fixedly connected to the outer surface of the fixing frame, a retaining ring is movably sleeved inside the fixing frame, a first spring is fixedly connected to the left side of the retaining ring, and the other end of the first spring is fixedly connected to the right side of the movable plate.

[0007] As a preferred embodiment of this utility model, a rotating rod is movably sleeved at the bottom of the outer shell, a rotary rod is fixedly connected to the bottom of the rotating rod, a handle is fixedly connected to the bottom of the rotary rod, and connecting rods are hinged to both the left and right sides of the rotary rod.

[0008] As a preferred embodiment of this utility model, the other end of the connecting rod is hinged to a connecting block, the outer surface of the connecting block is movably connected to the interior of the outer shell and the fixed frame respectively, and the other end of the connecting block is fixedly connected to a moving plate, the outer surface of the moving plate is movably connected to the inner surface of the fixed frame.

[0009] As a preferred embodiment of this utility model, a sliding plate is fixedly connected to the top of the moving plate, and a second spring is fixedly connected to the bottom of the sliding plate, with the bottom end of the second spring being movably connected to the top of the moving plate.

[0010] As a preferred technical solution of this utility model, a fixing block located on the right side of the rotating rod is fixedly connected to the bottom of the outer shell. A pull rod is movably sleeved inside the fixing block. The left end of the pull rod passes through the fixing block and extends to the outside of the fixing block and is fixedly connected to a locking block. A gear is meshed with the left side of the locking block. The inside of the gear is fixedly sleeved with the outer surface of the rotating rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention, by setting up a rotating shaft, a rotating rod, a sleeve rod, a round rod, and a movable plate, allows the rotating shaft to drive the rotating rod to rotate when the small motor starts running. This causes the sleeve rod to drive the round rod to move horizontally to the right under the limiting action of the outer shell. Consequently, the movable plate moves horizontally to the right along the inner surface of the fixed frame, ultimately compressing the first spring. This further compresses the first spring, thereby increasing the training intensity for the patient to fasten the buckle ring into the fixed frame. It also enables on-demand adjustment based on the patient's rehabilitation progress, improving the applicability and flexibility of the device and avoiding secondary injury to the patient due to excessive training intensity.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 6As shown, this utility model provides a hand rehabilitation training device, including a shell 1. A wrist support 2 is fixedly connected to the front of the shell 1. A fixed seat 3 located in the inner cavity of the wrist support 2 is fixedly connected to the front of the shell 1. A small motor 4 is fixedly connected inside the fixed seat 3. A rotating shaft 5 is fixedly sleeved at the other end of the output shaft of the small motor 4. A rotating rod 6 is fixedly sleeved at the other end of the rotating shaft 5. A sleeve rod 7 is movably connected to the outer surface of the rotating rod 6. A round rod 8 is fixedly connected to the right side of the sleeve rod 7. The other end of the round rod 8 passes through the shell 1 and extends into the inner cavity of the shell 1, and is movably sleeved to a fixed frame 11. A movable plate 9 is fixedly connected to the right end of the round rod 8. The outer surface of the movable plate 9 is movably connected to the inner surface of the fixed frame 11. When the small motor 4 starts running, the rotating shaft 5 will drive the rotating rod 6 to rotate, thereby causing the sleeve rod 7 to drive the round rod 8 to move horizontally to the right under the limiting action of the shell 1. This causes the movable plate 9 to move horizontally to the right along the inner surface of the fixed frame 11.

[0023] The inner surface of the outer shell 1 is fixedly connected to the outer surface of the fixation frame 11. The fixation frame 11 is movably fitted with a retaining ring 12. A first spring 10 is fixedly connected to the left side of the retaining ring 12. The other end of the first spring 10 is fixedly connected to the right side of the movable plate 9. When the patient puts his finger into the retaining ring 12 and pulls it, the patient will overcome the elastic force of the first spring 10 and press the retaining ring 12 into the fixation frame 11, thereby performing rehabilitation training for hand muscle strength.

[0024] The bottom of the outer casing 1 is movably fitted with a rotating rod 13, the bottom of the rotating rod 13 is fixedly connected to a rotary rod 14, the bottom of the rotary rod 14 is fixedly connected to a handle 15, and connecting rods 16 are hinged to both the left and right sides of the rotary rod 14. When the operator rotates the handle 15, the handle 15 will drive the rotary rod 14 and the rotating rod 13 to start rotating together, and the connecting rods 16 will move.

[0025] The other end of the connecting rod 16 is hinged to a connecting block 17. The outer surface of the connecting block 17 is movably connected to the interior of the outer shell 1 and the fixed frame 11, respectively. The other end of the connecting block 17 is fixedly connected to a moving plate 18. The outer surface of the moving plate 18 is movably connected to the inner surface of the fixed frame 11. When the connecting rod 16 moves, the connecting block 17 will cause the moving plate 18 to move horizontally left and right along the inner surface of the fixed frame 11 under the limiting action of the outer shell 1.

[0026] The top of the exercise plate 18 is fixedly connected to a sliding plate 19, and the bottom of the sliding plate 19 is fixedly connected to a second spring 20. The bottom end of the second spring 20 is movably connected to the top of the movable plate 9. When the exercise plate 18 moves, it will drive the sliding plate 19 to move closer to the buckle ring 12, so that the sliding plate 19 can enter the interior of the buckle ring 12, thereby increasing the training intensity of the buckle ring 12.

[0027] The bottom of the outer casing 1 is fixedly connected to a fixing block 22 located to the right of the rotating rod 13. A pull rod 23 is movably sleeved inside the fixing block 22. The left end of the pull rod 23 passes through the fixing block 22 and extends to the outside of the fixing block 22, and is fixedly connected to a locking block 24. A gear 21 is meshed on the left side of the locking block 24. The inside of the gear 21 is fixedly sleeved with the outer surface of the rotating rod 13. When the operator pulls the pull rod 23, the pull rod 23 will cause the locking block 24 to move horizontally to the right under the limiting action of the fixing block 22, thereby releasing the fixing effect on the gear 21 and the rotating rod 13.

[0028] Among them, the outer surface of the pull rod 23 is movably sleeved with a third spring 25. The left end of the third spring 25 is fixedly connected to the right side of the locking block 24, and the right side of the third spring 25 is fixedly connected to the left side of the fixing block 22. Due to the elastic force of the third spring 25, the locking block 24 will have a good reset effect in subsequent use, thereby ensuring that the locking block 24 can always mesh with the gear 21.

[0029] Working principle and usage process of this utility model:

[0030] The patient places their wrist on the wrist rest 2 and inserts their fingers into the four snap rings 12. Snapping the snap rings 12 causes them to overcome the elastic force of the first spring 10 and retract into the fixing frame 11, initiating hand rehabilitation training. When the training intensity needs adjustment to suit different patients' rehabilitation needs, the small motor 4 is activated, causing the rotating shaft 5 to rotate the rotating rod 6. This causes the sleeve rod 7 to move the round rod 8 horizontally to the right under the limiting action of the outer shell 1. Consequently, the movable plate 9 moves horizontally to the right along the inner surface of the fixing frame 11, ultimately compressing the first spring 10 and increasing the training intensity as the patient snaps the snap rings 12 into the fixing frame 11. This allows for on-demand adjustment based on the patient's rehabilitation progress, improving the device's applicability and flexibility, and preventing secondary injury to the patient from excessively high training intensity.

[0031] When the patient's recovery is progressing well and further training intensity is needed, first pull the lever 23 to disengage the locking block 24 from the outer surface of the gear 21, thereby releasing the fixing effect on the gear 21 and the rotating rod 13. Then rotate the handle 15 to rotate the rotating rod 14 and start the connecting rod 16 to move. At this time, under the limiting action of the outer shell 1, the connecting block 17 will drive the moving plate 18 and the sliding plate 19 to move closer to the retaining ring 12, so that the sliding plate 19 can enter the interior of the retaining ring 12. At this time, when the patient retains the retaining ring 12, he / she will need to overcome the elastic force of the first spring 10 and the second spring 20 at the same time, thus realizing the function of further increasing the intensity of hand muscle strength rehabilitation training. Similarly, the patient can start the small motor 4 to adjust the elastic force of the first spring 10 and the second spring 20 at the same time, so as to better adapt to the patient's own recovery status.
