Embodiment Construction

[0018] The present invention is further described in conjunction with the following examples.

[0019] see figure 1 , the mechanical frame includes motor base, slide rail, pulley, ball screw, limit block, micro switch, nylon wire, finger cot, finger frame, motor and so on.

[0020] The finger cot is printed by a 3D printer, which can be customized according to the hands of different patients, so that the size is appropriate, reducing the patient's discomfort and improving the training effect.

[0021] see figure 1 , No. 1 motor is installed on the frame of the whole machine. No. 1 motor adopts a ball screw drive device. No. 1 motor drives the ball screw to rotate forward and reverse. The ball screw drives the No. 1 finger frame to move left and right through the ball. The ball screw High positioning accuracy and good synchronization can greatly improve the rehabilitation effect. Install a micro switch at the upper and lower proper positions of the No. 1 finger frame respect...

Abstract

The invention discloses a finger rehabilitation training device. The device includes a mechanical frame, a smart terminal module, a main control module, an electric motor module, a safety protection module and a rehabilitation evaluation module. The mechanical frame includes a motor base, a slide rail, a pulley, a ball screw, a limiting block, a micro switch, a nylon thread, a finger frame and a finger sleeve. The transmission structure of a first motor is the ball screw. The main control module is STM32. The safety protection module is the limiting block and the micro switch, wherein the micro switch is embedded inside the limiting block. The rehabilitation evaluation module uses displacement sensors which are attached to the surfaces of a thumb and a forefinger respectively and are usedfor collecting the displacement amount of the movement of fingers. A finger training method is designed according to the device.

Description

technical field [0001] The invention relates to the field of rehabilitation training, in particular to a finger rehabilitation training device. Background technique [0002] The hand is very important in daily life. The structure of the hand is extremely delicate and complex. For patients who cannot open their fingers, it is difficult to recover the hand if they rely on themselves alone. If the conventional rehabilitation treatment plan is used, the treatment cycle Longer, more expensive, less likely to return fingers to original motion, and boring to the patient. Repeated and accurate practice is the key to coordination training, so how to restore the motor function of the patient's fingers is a very important thing. Hand movement includes gross movement and fine movement. Finger-to-finger is fine movement. Most traditional finger rehabilitation robots can only perform gross movement training, but cannot achieve fine movement of fingers. The thumb and index finger can perf...
