[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This device utilizes a structure including an elastic band, palm plate, silicone pad, finger sleeves, finger straps, and female and male buckles. The patient rests their hand on the palm plate, and the elastic band covers the palm. Each finger is adjusted to the appropriate position according to its length and the needs of the joints being trained. The finger sleeves are then secured with the female and male buckles. The patient's five fingers are inserted into the corresponding finger sleeves. The silicone pads have a certain degree of firmness and elasticity. When the patient bends their fingers upwards, up-and-down rehabilitation movements are performed on the joints of the fingers. This solves the problem that most existing rehabilitation training devices have fixed settings and are difficult to adjust according to the user's needs. The problem is that the pressing mechanism is detachably installed on the silicone pad by the second and first Velcro straps.

[0028] Please see Figure 1-6A hand function rehabilitation training device for hemiplegic patients after stroke includes a palm plate 6. An elastic band 10 is located on the top of the palm plate 6, with both ends of the elastic band 10 fixedly attached to the top sides of the palm plate 6. The patient's hand can pass through the elastic band 10, which can restrain the wrist. A silicone pad 1 is fixedly attached to one side of the palm plate 6. Five finger straps 3 are located on the side wall of the palm plate 6 corresponding to the patient's fingers, positioned above the silicone pad 1. The end of each finger strap 3 away from the palm plate 6 is fixedly attached to the top of the silicone pad 1, and a positioning strap 2 is fixedly attached to the end of each finger strap 3 away from the palm plate 6, also fixed to the top of the silicone pad 1. Each finger strap 3 is adjustable. A finger sleeve 4 is fitted with several female buckles 18 fixedly installed at the bottom of the finger sleeve 4. Several female buckles 14 are evenly fixed horizontally on the back of the finger strap 3. The female buckles 18 and female buckles 14 are fastened together. The patient's back of hand rests on the palm plate 6, and the elastic band 10 is placed on the palm. According to the length of the patient's fingers and the needs of joint training, each finger sleeve 4 is adjusted to a suitable position. The finger sleeve 4 is then fastened by the female buckles 18 and female buckles 14. The patient's five fingers are inserted into the finger sleeve 4. The silicone pad 1 has a certain degree of hardness and elasticity. When the patient bends their fingers upward, the joints of the patient's fingers can be exercised up and down.

[0029] The finger sleeve 4 has lateral pressure mechanisms installed on both the front and back sides. Each lateral pressure mechanism includes a lateral pressure rubber pad 20, and a lateral pressure sensor 21 is fixedly installed on the inner side of the lateral pressure rubber pad 20. The side of the lateral pressure sensor 21 away from the lateral pressure rubber pad 20 is fixed to the inner side of the finger sleeve 4. With this rehabilitation trainer, when the fingers are brought together or spread to the side, the corresponding lateral pressure rubber pad 20 inside the finger sleeve 4 is compressed, thus pressing against the lateral pressure sensor 21. Through the lateral pressure mechanisms installed on both the front and back sides of the finger sleeve 4, the strength of the fingers in bringing together and spreading to the side can be trained under the action of the lateral pressure rubber pad 20. ， The pressure sensor 19 is connected to the pressure display device via a wireless network. The pressure display device can display the pressure level when the patient applies pressure to the side in a timely manner, which is convenient for monitoring the recovery of strength training in each finger.

[0030] Lateral compression devices help train the lateral movement of the fingers, including finger clenching and lateral extension. This is especially important for stroke patients with hemiplegia, as they may experience problems such as clenched fingers, spasms, and stiffness. Lateral compression training can help improve these problems. Through lateral compression, the muscles of the hand can be strengthened, which is very important for restoring hand function and improving daily living abilities.

[0031] A pressing mechanism is detachably installed on the top of the silicone pad 1. The pressing mechanism includes a disc 12. A second Velcro 13 is fixedly installed on the bottom of the disc 12. A first Velcro 5 is fixedly installed on the top of the silicone pad 1. The first Velcro 5 is located on the side near the palm plate 6. The second Velcro 13 and the first Velcro 5 are glued together. The disc 12 is hollow inside. A pressing rubber pad 17 is fixedly installed inside the disc 12. Five perforations 15 are provided on the side wall of the disc 12 corresponding to the finger sleeve 4. A pressing block 11 is inserted through the perforations 15. A support rod 16 is fixedly installed on the bottom of the pressing block 11. A pressing sensor 19 is fixedly installed on the end of the support rod 16 away from the pressing block 11. The pressing sensor 19 is fixed to the side wall of the pressing rubber pad 17. The pressing mechanism is detachably installed on the silicone pad 1 through the mutual adhesion of the second Velcro 13 and the first Velcro 5.

[0032] When the patient's fingers are bent, they press the pressure block 11 with their fingertips. Since the pressure block 11 is fixedly connected to the support rod 16, and the pressure sensor 19 is located between the support rod 16 and the pressure rubber pad 17, pressing the pressure block 11 generates pressure on the pressure sensor 19, thus enabling finger strength rehabilitation training for the patient. The pressure sensor 19 is connected to a pressure display device via a wireless network. The pressure display device can easily display the pressure applied by the patient during pressing, facilitating the monitoring of the recovery status of each finger's strength training. A soft pad 7 is fixedly installed on the top of the palm plate 6. The soft pad 7 is made of sponge material, and the two ends of the elastic band 10 are located on the outer side of the soft pad 7. The soft pad 7 improves the comfort of the palm or back of the hand resting on the palm plate 6.
