Specific implementation manner

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] For Embodiment 1, please refer to Figure 1-2 , the present utility model discloses a hand rehabilitation trainer for hemiplegic patients, including a training table 1, a track disk 2 is arranged on the training table 1, and a driving device 3 is arranged on the track disk 2.

[0026] One side of the inner wall of the track disk 2 is provided with guide rail teeth 23, and a track groove 24 is opened at the bottom of the inner wall of the track disk 2.

[0027] The driving device 3 includes a driving box 31 slidably arranged on the track disk 2, a motor 32 is arranged inside the driving box 31, the output end of the motor 32 extends into the track disk 2 and is provided with a gear 33 meshing with the guide rail teeth 23, and guide rods 37 are arranged at the bottoms of both sides of the driving box 31, and the bottoms of the two guide rods 37 respectively extend into the inner ring and outer ring of the track disk 2.

[0028] Specifically, the guide rail teeth 23 are arranged on the inner side of the inner wall of the track disk 2, the track disk 2 is rectangular, the track disk 2 includes a plurality of modular straight-throughs 21 and modular elbows 22, the modular straight-throughs 21 and modular elbows 22 are spliced with each other, the guide rail teeth 23 are arranged on one side of the inner walls of the modular straight-throughs 21 and modular elbows 22, and the track groove 24 is opened at the bottoms of the inner walls of the modular straight-throughs 21 and modular elbows 22. Please refer to Figure 1 and Figure 2, several of the modular straight-throughs 21 form the four sides of the track plate 2, and the modular elbows 22 are assembled at the four corners of the four track plates 2. The modular design of the track plate 2 enables the length and width of the track plate 2 to be adjusted independently, resulting in better training effects. When disassembling the track plate 2, simply lift the modular straight-throughs 21 and modular elbows 22 vertically to drive the positioning rod 39 to disengage from the positioning groove 11. By directly lifting the grip 34, the gear 33 can be separated from the guide rail teeth 23, and at the same time, the disc 35 can be separated from the track groove 24, making disassembly and assembly more convenient.

[0029] Specifically, a disc 35 is slidably sleeved inside the track groove 24 through a connecting rod at the bottom of the drive box 31. A slip ring 36 is sleeved on the surface of the disc 35 through a bearing. A number of balls are movably nested at the bottom of the disc 35. The settings of the slip ring 36 and the balls effectively reduce the friction between the disc 35 and the track groove 24. The setting of the disc 35 ensures the stability between the gear 33 and the guide rail teeth 23, making the gear 33 always remain in a meshed state with the guide rail teeth 23. When the motor 32 is started, the motor 32 drives the gear 33 to rotate. The gear 33 meshes with the guide rail teeth 23, causing the drive box 31 to drive the grip 34 to move along the track of the track plate 2.

[0030] Specifically, a guide roller 38 is sleeved on the outside of the guide rod 37 through a bearing. The guide rod 37 cooperates with the guide roller 38 to limit the drive box 31, ensuring the stability of the drive box 31 and making the meshing process between the gear 33 and the guide rail teeth 23 more stable.

[0031] Specifically, a number of positioning grooves 11 are opened at the top of the training table 1. The bottoms of the modular straight-throughs 21 and modular elbows 22 are both provided with no less than one positioning rod 39, and the bottom end of the positioning rod 39 is inserted into the inside of the positioning groove 11.

[0032] Specifically, a grip 34 is fixedly arranged at the top of the drive box 31. A rotating cylinder 341 is movably sleeved on the outside of the grip 34. After the patient's hand penetrates into the finger trainer 4, the setting of the rotating cylinder 341 enables the rotating cylinder 341 not to rotate with the grip 34 when the grip 34 rotates, preventing the user's hand from being sprained.

[0033] Specifically, it further includes a finger trainer 4. The finger trainer 4 is movably clamped on the rotating cylinder 341 through a clamp 41. The finger trainer 4 is a common finger rehabilitation training device on the market. After wearing it, it can independently drive the patient's fingers to curl and open through the pneumatic principle. The setting of the clamp 41 facilitates the separation of the finger trainer 4 from the rotating cylinder 341.

[0034] Specifically, a fixed rod 12 is provided on one side of the training table 1. An activity tube 13 is movably sleeved on the top of the fixed rod 12. An activity rod 14 is movably inserted into the interior of the activity tube 13. One end of the activity rod 14 is movably sleeved with the top of the grip 34. The activity rod 14 is used to hang the power supply line of the motor 32 and the air pipe of the finger trainer 4. At the same time, the activity rod 14 can stretch or drive the activity tube 13 to rotate in the activity tube 13 along with the movement of the grip 34. When the grip 34 is lifted, the activity tube 13 is driven to slide on the fixed rod 12 through the activity rod 14.

[0035] Embodiment 2. Refer to Figure 1-3 , compared with the above embodiment, the guide rail teeth 23 in this embodiment are installed on the outer side of the inner wall of the track disk 2. By combining the modular straight-through 21 and the modular elbow 22 in this embodiment with the modular straight-through 21 and the modular elbow 22 in the above embodiment, track disks 2 of different shapes can be assembled, so that the user's hand can perform movements along different tracks to achieve the best training effect.

[0036] In summary, compared with the existing trainers on the market, this hand rehabilitation trainer for hemiplegic patients can actively drive the patient's hand to move along the track of the track disk 2 through the motor 32 for rehabilitation training. The modular design of the track disk 2 enables medical staff to assemble track disks 2 of different shapes and sizes according to the training intensity of the patient to achieve the best rehabilitation training effect.
