Description

Technical Field

[0001] This utility model relates to a finger rehabilitation training device, belonging to the field of medical device technology. Background Technology

[0002] Finger rehabilitation training devices are commonly used to rehabilitate the function of patients' fingers. For example, Chinese patent document CN221731443U discloses a finger extension rehabilitation device, which is used for training patients who have difficulty straightening their fingers. Patients need to use training equipment that matches the length of their fingers during finger rehabilitation training. However, existing rehabilitation devices rely on the elasticity of a metal spring plate to provide the restoring force. The length of the metal spring plate is not adjustable, which can cause inconvenience to patients with different finger lengths and affect the hand rehabilitation effect. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a finger rehabilitation training device that overcomes the defect that the length of the metal spring plate in the prior art cannot be adjusted. Instead, it uses a pull rope to connect multiple blocks to form an elastic varicose vein component, and the length of the elastic varicose vein component can be adjusted by adjusting the number of blocks.

[0004] To achieve the above objectives, this utility model provides a finger rehabilitation training device, comprising a base plate, a pull rope, a tension spring, and multiple blocks. A strap is provided on the base plate to bind the base plate to the back of the patient's hand. The base plate has a mounting groove and a through hole, one end of which extends to the mounting groove and the other end to the edge of the base plate. One end of the tension spring is fixed to the side wall of the mounting groove, and the other end is connected to the pull rope, which passes through the through hole and extends forward. Through holes are provided on each block, and the distal end of the pull rope sequentially passes through the through holes of multiple blocks to connect them into a series. An anti-detachment block is provided at the end of the pull rope to prevent the blocks from detaching outwards. A finger loop is provided on at least one block near the distal end of the pull rope.

[0005] The block is spherical.

[0006] The block is I-shaped and includes an upper plate, a lower plate, and a connecting part connecting the upper plate and the lower plate. The upper plate and the lower plate have arc-shaped edges at both ends, and the connecting part has inwardly concave arc-shaped surfaces on both sides. The arc-shaped surfaces and the arc-shaped edges are smoothly connected.

[0007] The anti-detachment block is spherical.

[0008] The finger collar is bonded and fixed to the lower end surface of the lower plate.

[0009] An arc-shaped support plate for supporting the patient's finger is also fixedly provided on the inner side of the finger loop and at the end away from the lower plate.

[0010] A screw hole is provided on the side wall of the mounting groove, a screw is screwed into the screw hole, and a hanging ring is provided at the end of the screw, and the end of the tension spring is hung on the hanging ring.

[0011] By adopting the above technical solution, the finger rehabilitation training device of this utility model has the following beneficial effects compared with the prior art:

[0012] 1. The elastic tension component is formed by connecting modular blocks with a pull rope. The length of the device can be flexibly adjusted by increasing or decreasing the number of blocks to adapt to the finger size of different patients, thus solving the defect of fixed length of traditional metal spring plates.

[0013] 2. By connecting I-shaped or spherical blocks together, the joints can be made flexible.

[0014] 3. The modular design allows for adjustments to the number of blocks or the strength of springs according to the rehabilitation progress, adapting to the training needs of different stages and improving rehabilitation effectiveness. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1:

[0024] like Figure 1 ,2 As shown, the finger rehabilitation training device of this utility model includes a base plate 1, a pull rope 2, a tension spring 3, and multiple blocks 4. A strap 5 is provided on the base plate 1 for binding the base plate 1 to the back of the patient's hand. A mounting groove 6 and a perforation 7 are provided on the base plate 1, with one end of the perforation 7 extending to the mounting groove 6 and the other end extending to the edge of the base plate 1.

[0025] One end of the tension spring 3 is fixed to the side wall of the mounting groove 6, and the other end is connected to the pull rope 2. The pull rope 2 passes through the through hole 7 and extends forward. A through hole 40 is provided on the block 4. The distal end of the pull rope 2 passes through the through holes 40 of multiple blocks 4 in sequence to connect multiple blocks 4 into a series. An anti-detachment block 8 is provided at the end of the pull rope 2 to prevent the block 4 from detaching outward. A finger loop 9 is provided on at least one block 4 near the distal end of the pull rope 2.

[0026] In this embodiment, the block 4 is spherical.

[0027] Example 2:

[0028] like Figures 3-6 As shown, in this embodiment, the block 4 is I-shaped, including an upper plate 41, a lower plate 42, and a connecting portion 43 connecting the upper plate 41 and the lower plate 42. The upper plate 41 and the lower plate 42 each have arc-shaped edges 400 at both ends. The connecting portion 43 has inwardly concave arc-shaped surfaces 430 on both sides. The arc-shaped surfaces 430 and the arc-shaped edges 400 are smoothly connected.

[0029] Because the tension spring 3 applies tension to the pull rope 2, in the natural state, the upper plate portion 41 of adjacent I-shaped blocks 4 abuts against each other, and the lower plate portion 42 abuts against each other, thus the elastic flexural component formed by the pull rope 2 connecting multiple blocks 4 is in a straight state. When the patient wears the device, under the action of finger bending force, the two adjacent I-shaped blocks 4 at the finger joint will bend to form an angle, thus causing the upper plate portion 41 of the two adjacent I-shaped blocks 4 at that position to separate from each other, with only the lower plate portion 42 abutting against each other.

[0030] In this embodiment, the anti-detachment block 8 is spherical, and the spherical anti-detachment block 8 can enter the arc-shaped surface 430 of the connecting part 43.

[0031] like Figure 6As shown, the finger loop 9 is bonded and fixed to the lower end face of the lower plate 42. An arc-shaped support plate 91 for supporting the patient's finger is also fixedly provided on the inner side of the finger loop 9 and at the end away from the lower plate 42. This arc-shaped support plate 91 is a rigid plate, and its function is to prevent the finger loop 9 from injuring the patient's finger skin. Furthermore, the width of the arc-shaped support plate 91 can be set to be greater than the width of the finger loop 9 to increase its contact area with the patient's finger skin and further reduce pressure.

[0032] A screw hole is provided on the side wall of the mounting groove 6, and a screw 61 is screwed into the screw hole. A hanging ring 62 is provided at the end of the screw 61, and the end of the tension spring 3 is hung on the hanging ring 62. In this embodiment, as... Figure 7 As shown, four mounting slots 6 are provided on the base plate 1, corresponding to the mounting of four tension springs 3 and pull ropes 2, for rehabilitation training of the patient's four fingers. Of course, in other embodiments, other numbers of tension springs 3 and pull ropes 2 can also be provided. In addition, a larger mounting slot 6 can be provided to install multiple tension springs 3 in this single mounting slot 6.

[0033] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
