[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0017] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The utility model provides a technical solution: a buffer device for hand rehabilitation treatment, comprising an arm support plate 1, a side wall of the arm support plate 1 is provided with an assembly groove 2, and a buffer plate 3 rotatably connected thereto is assembled in the assembly groove 2, such as Figure 2 As shown in the figure, the front and rear side walls of the buffer plate 3 are integrally formed with a rotating shaft 31, and the buffer plate 3 is rotatably connected to the assembly groove 2 through the rotating shaft 31. The side wall of the arm support plate 1 is integrally formed with a mounting shell 4, and a driving motor 5 is embedded in the mounting shell 4. The output end of the driving motor 5 is fixedly connected to the rotating shaft 31 at the front end of the buffer plate 3 through a coupling.

[0018] The buffer plate 3 is driven by the driving motor 5 to rotate in different directions in the assembly groove 2, so as to buffer the downward sliding movement of the hand undergoing electrical stimulation rehabilitation treatment, thereby improving the comfort of the patient's hand during the electrical stimulation rehabilitation treatment.

[0019] like Figure 1 and Figure 4 As shown in the figure, driving components 7 are respectively installed in the buffer plate 3 and the arm support plate 1, and the output end of the driving motor 5 is driven by the arranged driving component 7 to move. The driving component 7 includes a pressure sensor 71, and the pressure sensor 71 is embedded and installed in the mounting groove 72, and the mounting groove 72 is arranged on the surface of the buffer plate 3. The pressure sensor 71 is electrically connected to a signal converter 73, and the signal converter 73 is embedded and installed at the bottom of the arm support plate 1. The signal converter 73 is electrically connected to a control circuit board 74, and the control circuit board 74 is electrically connected to an external power supply and an input end of the driving motor 5. During use, the buffer plate 3 is used to place the palm. The buffer plate 3 is arranged in an arc shape, which is adapted to the shape of the palm in a relaxed state to improve the comfort between the palm and the buffer plate 3. Through the detection of pressure changes by the pressure sensor 71, the control circuit board 74 can send a control signal to the driving motor 5 to control the rotation direction of the output end of the driving motor 5, and the driving motor 5 drives the movement of the buffer plate 3 to provide buffering for the overall fall of the palm;

[0020] The pressure sensor 71 uses the model: FSR402 resistive flexible film pressure sensor, which can effectively detect the pressure applied. The sensor is assembled in the mounting groove 72 in a strip shape to improve the sensitivity of detecting the pressure applied by the finger. The drive motor 5 uses the model: JGM12-15BY micro DC stepper motor. The motor is a two-phase four-wire all-metal gear motor with a reduction ratio of 1:50 and a large torque. After the drive motor 5 receives the control signal from the control circuit board 74, the output end drives the buffer plate 3 to move through the rotating shaft 31.

[0021] like Figure 1 and Figure 3 As shown in the figure, the surface of the arm support plate 1 is provided with a mounting opening 8 which passes through the arm support plate 1, and the number of the mounting openings 8 is at least four. The four mounting openings 8 are distributed from left to right in groups of two, and each group of mounting openings 8 is respectively equipped with a strap 9. By setting the strap 9, the arm support plate 1 can be tied and fixed to the arm.

[0022] A sponge layer 6 is adhered and fixed to the surface of the arm support plate 1, and the sponge layer 6 is provided to improve the comfort of the arm after the arm support plate 1 and the arm are bound together.

[0023] Working principle: This device is suitable for hand movement dysfunction caused by stroke or other brain injury diseases. At present, most of the hand movement dysfunction is treated by electrical stimulation. The process of electrical stimulation is that when the hand is electrically stimulated, it will lift up along the wrist. Without electrical stimulation, the hand will fall quickly along the wrist. The overall rehabilitation treatment process is to repeatedly electrically stimulate the hand. During the repeated electrical stimulation of the hand, the palm will lift and fall along the wrist many times. During the electrical stimulation treatment of the hand, the device is tied to the patient's arm. In the initial state, the buffer plate 3 and the arm support plate 1 are in a horizontal state, and the palm is in a natural state and fits with the buffer plate 3. When the hand is electrically stimulated, the palm is lifted up. At this time, since the pressure sensor 71 cannot detect the pressure, the signal is transmitted to the control circuit board 74 through the signal converter 73. The control circuit board 74 controls the drive motor 5 to Figure 2 In the direction shown in the figure, the buffer plate 3 rotates clockwise, and the buffer plate 3 will flip over in the assembly slot 2, and move synchronously with the raised palm. When the electrical stimulation signal disappears, the palm will flip down along the wrist, and the fingers of the palm will first contact the pressure sensor 71. After detecting the pressure, the pressure sensor 71 transmits it to the control circuit board 74 through the signal converter 73. At this time, the control circuit board 74 controls the output end of the drive motor 5 to rotate slowly in the counterclockwise direction, and the buffer plate 3 moves downward in the assembly slot 2. The buffer plate 3 can support and buffer the palm without affecting the falling action of the palm. When the hand is electrically stimulated again, the palm is lifted up, and the buffer plate 3 repeats the above process. The action process of the control circuit board 74 controlling the output end of the drive motor 5 is a mature application of the prior art, and no corresponding specific control program needs to be set. Therefore, the action process of the control circuit board 74 controlling the drive motor 5 is no longer described. Through this device, the palm can be effectively supported during multiple palm lifting and lowering processes, reducing the discomfort during the rapid falling of the palm, and improving the comfort during the hand rehabilitation electrical stimulation treatment.
