[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Reference Figure 1 to Figure 2 As shown, this embodiment provides a fistula-side arm activity training device, including a palm plate 2, a finger training component is fixedly connected to the palm plate 2 near the wrist, wrist straps 1 are fixedly connected to both sides of the finger training component, and fixing parts are provided at both ends of the wrist straps 1;

[0025] The finger training component includes a rebound piece mounting shell 3 fixedly connected to the wrist strap 1, at least one group of finger resistance components is arranged inside the rebound piece mounting shell 3, the finger resistance component includes an elastic component 7 arranged in the rebound piece mounting shell 3, and a resistance adjustment part arranged in the rebound piece mounting shell 3, the elastic component 7 is fixedly connected to one end of a rope body 15, the other end of the rope body 15 is fixedly connected to the finger fixing part, and the middle part of the rope body 15 bypasses the resistance adjustment part; the side of the rebound piece mounting shell 3 away from the palm plate 2 is fixedly connected to an upper arm compression component.

[0026] When in use, the wrist strap 1 is tied to the wrist through the fixing part, and one end of the pull rope 11 is fixed to the finger through the finger fixing part. The elastic member 7 provides the rope body 15 with the resistance required for exercise. When the exercise intensity needs to be adjusted, the resistance adjustment part is adjusted, and the position of the resistance adjustment part relative to the elastic member 7 changes. When gripping exercises are needed, the rebound member mounting shell 3 is set on the back of the hand, and gripping exercises can be performed. Since the rope body 15 of the present invention can be provided with multiple ones, the whole device can be synchronized with the finger exercise for exercise, which increases the items of exercise content and is more conducive to the patient's recovery.

[0027] A further optimized solution is that the resistance adjusting part includes a winding wheel 8 which is slidably arranged in the back-force member mounting shell 3, and the middle part of the rope body 15 passes around the winding wheel 8.

At this time, the position of the winding wheel 8 relative to the elastic member 7 changes, thereby achieving the purpose of adjusting the exercise intensity. The rope body 15 is arranged in a way of bypassing the winding wheel 8. The displacement of the winding wheel 8 is equivalent to half of the pulling amount of the elastic member 7. Compared with the conventional adjustment of the pulling amount of the elastic member 7, the amount is reduced by half, so that the displacement of the rack 9 is reduced.

[0031] The adjusting knob 12 and the gear shaft 1001 can be splined. When the exercise force needs to be adjusted, the adjusting knob 12 is pulled out and rotated. The adjusting knob 12 drives the gear shaft 1001 to rotate to achieve the purpose of adjusting the exercise force. When the force is adjusted to an appropriate size, the adjusting knob 12 is pressed down in the direction of the rebound member mounting shell 3. At this time, the pin 1201 is inserted into the column slot for fixation.

[0032] According to a further optimization scheme, the elastic member 7 is a spring, the center line of the elastic member 7 is parallel to the rope body 15 , one end of the elastic member 7 is fixedly connected to the inner wall of the rebound member mounting shell 3 , and the other end of the elastic member 7 is fixedly connected to one end of the rope body 15 .

[0033] According to a further optimized solution, the fixing portion includes first Velcro strips 13 fixedly connected to two ends of the wrist strap 1, and the two first Velcro strips 13 are bonded together.

[0034] According to a further optimized solution, the finger fixing portion includes a second Velcro 14 fixedly connected to the other end of the rope body 15, and the width of the second Velcro 14 is 0.5 cm.
