Rope traction type finger rehabilitation training device

Abstract

The invention discloses a rope traction type finger rehabilitation training device which comprises a mechanical frame, a main control module, a safety module and a rehabilitation evaluation module. The mechanical frame comprises a support base, a motor groove, a motor follow-up lever, a transfer rod, a soft structure glove, a spring fixing rod, a spring, a nylon rope, a thumb frame, a fingerstallof the thumb frame, glove fixing steel strips and an emergency stop button. The nylon rope is a transmission structure for a motor; the main control module is an STM32 main control module; the safetymodule comprises pressure sensors and the emergency stop button, the pressure sensors are embedded into the front side and the rear side of the inside of a fingerstall of each finger, and the emergency stop button is arranged on a glove fixing rod; the rehabilitation evaluation module comprises strain gauge torque sensors and pressure sensors, the strain gauge torque sensors are arranged at four finger joints, and the pressure sensors are arranged at the front ends of the fingerstalls. A finger training method is designed according to the rope traction type finger rehabilitation training device.

Description

technical field [0001] The invention relates to the field of rehabilitation training, in particular to a hand rehabilitation training device. Background technique [0002] Fingers are one of the most important and delicate organs of human beings. Among all kinds of disabilities and traumas, hand injuries account for a large proportion. In addition to finger trauma, the elderly also need finger rehabilitation training due to stroke or hemiplegia. The structure of the hand is extremely delicate and complex, which makes it difficult to recover from finger injury or stroke, and the treatment cycle is longer. The probability of the finger recovering the original motor function is relatively small. Patients can take care of themselves to a certain extent. Traditional rehabilitation therapists spend a lot of money on treatment. For patients with financial difficulties, they may not be able to receive sufficient treatment to overcome their injuries. At the same time, they may not re...

Problems solved by technology

[0007] Aiming at the problem that finger injury patients can only recover naturally after surgery and the recovery period is long, and the existing finger rehabilitation devices are all problems of grasping training, the present invention proposes a device with simple structure, low price, good stability and high safety. It is a finger rehabilitation device that can complete finger grasping training and align the thumb with the index finger, middle finger, ring finger, and little finger respectively. The main control chip is used to control the finger rehabilitation device as a whole; the strain gauge pressure sensor is used to detect muscle spasm. Cooperate with the emergency stop button to ensure the safety of the training process; use RFP bending sensor and strain gauge pressure sensor to guide the rehabilitation training of finger grasping and finger alignment, and detect the effect of rehabilitation training; use an elastic matching algorithm for rehabilitation evaluation: by time and The value set composed of the data values ​​measured by the sensor; the point set is selected; the data matching between normal people and patients is carried out based on constraints such as endpoint constraints, continuity constraints, and monotonic constraints, and the similarity is judged, which can make finger rehabilitation training more scientific And perfect, it solves the problem that the existing finger rehabilitation device is not stable and cannot be evaluated for rehabilitation
