One end of the training rope is connected to the winding device, and the other end extends upward and passes through the plurality of opposite guide holes to connect with the finger loop.

[0011] Furthermore, the mounting bracket also includes a plurality of washers respectively fitted inside the guide hole.

[0012] Furthermore, the top of the first fixing plate is provided with a connecting plate that connects to the mounting base plate, and the mounting base plate is provided with connecting bolts that connect to the connecting plate.

[0013] Furthermore, the control mechanism includes four winding motors respectively connected to four winding units and mounted on the mounting base, a controller connected to the four winding motors and mounted on the mounting base, a display screen connected to the controller, and four control buttons connected to the controller.

Detailed Implementation

[0026] The present invention will be further described below through specific embodiments.

[0027] Reference Figures 1 to 6 As shown, a rehabilitation training device for patients with finger burns includes a fixation mechanism 1 and a finger training mechanism 2.

[0028] The fixing mechanism 1, fixed to the forearm, includes a first fixing plate 11 and a second fixing plate 12 arranged vertically, an adjusting fixing component 13 disposed between the first fixing plate 11 and the second fixing plate 12, and a flexible hand-grip ball 14 disposed at the front end of the second fixing plate 12 that can be supported in the palm of the hand. The forearm is fixed between the first fixing plate 11 and the second fixing plate 12 via the adjusting fixing component 13. The top of the first fixing plate 11 is provided with a connecting plate 15 that connects to the finger training mechanism 2. The finger training mechanism 2 is fixed to the connecting plate 15 by connecting bolts 16. Specifically, the front end of the first fixing plate 11 has an upwardly bent portion 111 that is opposite to the flexible hand-grip ball 14, so that a space for the fingers to bend upward is formed between the bent portion 111 and the flexible hand-grip ball 14. Furthermore, the flexible hand-grip ball 14 is made of flexible rubber, which greatly reduces the discomfort to the palm of the hand when gripping it.

[0029] The adjusting and fixing assembly 13 includes a plurality of adjusting and fixing members disposed opposite to each other on the first fixing plate 11 and the second fixing plate 12. Each adjusting and fixing member includes a first fixing ring 131 disposed on one side of the first fixing plate 11, a second fixing ring 132 disposed on one side of the second fixing plate 12 opposite to the first fixing ring 131, and an adjusting belt 133 connecting the first fixing ring 131 and the second fixing ring 132. Specifically, the adjusting belt 133 includes an adjusting belt body 134 and an adjusting buckle 135 disposed at one end of the adjusting belt body 134. The free end of the adjusting belt body 134 passes sequentially around the first fixing ring 131 and the second fixing ring 132 before connecting to the adjusting buckle. Furthermore, the adjusting buckle 135 is a commonly used component in the field of adjusting shoulder straps; its specific structure and the principle of its telescopic adjustment will not be further elaborated here.

[0030] The finger training mechanism 2 is located on the top of the first fixed plate 11 and includes four finger loops that can be fitted onto the fingers other than the thumb; a mounting base 4 located on the top of the first fixed plate 11; four winders 5 located on the top of the mounting base 4; four training pull ropes 6 connected between the four winders 5 and the four finger loops 3; and a control mechanism 7 located on the mounting base 4 that is connected to and controls the four winders 5 to work independently. Specifically, the finger loop 3 includes a loop body 31 and a connecting ring 32 fitted around the outer periphery of the loop body 31, and one end of the training pull rope 6 is connected to the connecting ring 32.

[0031] Mounting base 4 includes a mounting base plate disposed on top of the first fixing plate 11 and a mounting bracket 42 disposed on the mounting base plate 41 and extending outwardly. One end of the training rope 6 is connected to the winding device 5 and the other end extends upward along the mounting bracket 42 to be connected to the opposite finger loop 3.

[0032] The mounting bracket 42 includes an extension rod 43 that bends upward and extends from the mounting base plate 41, and a plurality of guide plates 44 spaced apart along the extension direction of the extension rod 43. Specifically, the guide plates 44 are provided with four guide holes 45 spaced apart. One end of the training rope 6 is connected to the winding device 5, and the other end extends upward and passes through the plurality of guide holes 45 to connect with the finger collar 3. Furthermore, the mounting bracket 42 also includes a plurality of washers 46 respectively fitted on the inner edge of the guide holes 45 to prevent the training rope 6 from rubbing against the inner edge of the guide holes 45 and causing damage to the training rope 6.

[0033] The control mechanism 7 includes four winding motors 71 mounted on the mounting base 41 and connected to four winding devices 5 respectively; a controller 72 mounted on the mounting base 41 and connected to the four winding motors 71; a display screen 73 connected to the controller 72; and four control buttons 74 connected to the controller 72. The four control buttons 74 can work in conjunction with the controller to individually control the operation of the winding motors 71 to meet the requirements of differentiated rehabilitation training. During rehabilitation training, the winding motors 71 control the winding devices 5 to wind up the corresponding training ropes 6, thereby causing the corresponding fingers to bend upwards. The system is highly automated, and each winding device 5 can work independently, making it convenient to train each finger with different intensities according to the burn scar condition, thereby improving the scar recovery. Specifically, the controller 72 can be a microcontroller or other controllers that can achieve the specified effect. The specific model selection and working principle will not be further elaborated here.

[0034] During rehabilitation training, the fixation mechanism 1 is fixed to the forearm by adjusting the fixation component 13 in conjunction with the first fixation plate 11 and the second fixation plate 12. Then, the finger loops 3 are put on the fingers other than the thumb. The control mechanism 7 controls the four retractors 5 to work, and repeatedly retract-release-retract the corresponding training ropes 6 to drive the extension and contraction of the fingers, thereby promoting the rehabilitation of burn scars.

[0035] This application defines the structure of the rehabilitation training device and sets up a control mechanism 7 to independently control the operation of four retractors 5, which in turn control the operation of four finger loops 3, in order to meet the differentiated rehabilitation training needs of different burn conditions. The overall device is simple, highly automated, and suitable for burn patients with severe burns who cannot automatically retract their fingers. At the same time, each retractor can work independently, which makes it easy to train each finger with different intensities according to the burn scar condition, thereby improving the speed of scar recovery.

[0036] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be construed as limiting the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model application and the contents of the specification should still fall within the scope of the present utility model application.
