Wearable type pneumatic muscle and knuckle active/passive rehabilitation training device

Abstract

The invention provides a wearable type pneumatic muscle and knuckle active/passive rehabilitation training device which is capable of effectively assisting a patient to finish repeated functional trainings of multi-knuckle compound motions of fingers. The training device comprises a wearable support, a metacarpophalangeal joint two-way, a finger-near joint two-way, a finger-far joint two-way, a fingertip two-way and an air pipes. Finger-far joint pneumatic muscles are fixed on the metacarpophalangeal joint two-way and the finger-near joint two-way and communicated with the finger-far joint two-way. Finger-near joint pneumatic muscles are fixed on the finger-far joint two-way and the finger-near joint two-way and communicated with the finger-near joint two-way. Metacarpophalangeal joint muscles are fixed on the finger-near joint two-way and the metacarpophalangeal joint two-way and communicated with the metacarpophalangeal joint two-way. According to the invention, the training device used for simulating degree of freedom of knuckles; larger work space can be provided in a rehabilitation training; the knuckles are provided with active and passive assisting trainings; by use of the wearable structure, the training device is simple in structure, light and highly targeted in trainings, and can be directly used on fingers of a patient, and for active and passive cooperative trainings of knuckles in a complex training mode.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, in particular to a wearable pneumatic muscle finger joint active and passive rehabilitation training device. Background technique [0002] With the development of science and technology and the improvement of living standards, people have higher and higher requirements for the quality of life. Using rehabilitation robots to carry out rehabilitation training for the disabled and neurological patients is recognized as one of the important ways to improve their quality of life. . Fingers are a very important part of the human body, and most activities of people need the assistance of hands to complete. At present, the number of patients with hand dysfunction caused by central nervous system injuries such as spinal injuries, traumatic brain injuries, cerebral palsy, strokes, and peripheral nervous system injuries such as hand trauma, hand muscle injuries, and soft tissue injuries has incre...

AI Technical Summary

Problems solved by technology

[0003] Clinically, the hand dysfunction of disabled patients often manifests as flexion contracture, the flexor muscles of the hand are dominant, the interphalangeal joints and interphalangeal joints are difficult to stretch, and even simple grasping functions cannot be realized. At the same time, peripheral nerve damage in the hand will cause Causes abnormal bioelectric conduction. Patients often suffer from muscle weakness due to hand trauma. If rehabilitation training cannot be carried out effectively, Uken can cause hand muscle atrophy and pain. Therefore, spasm and muscle atrophy are the primary problems to be solved in hand function rehabilitation

[0004] The Chinese patent application with the publication number CN101015493A discloses a pneumatic flexible finger rehabilitation device, but the disadvantages of the above scheme are: 1. The rehabilitation device includes a pneumatic flexible finger bending joint, and the functional parts of the flexible bending joint mainly include rubber tubes and nested joints. The metal wire in the rubber tube wall, that is, the bending of the rubber tube drives the bending of the finger, and the use of the metal wire for auxiliary movement belongs to the early passive training of patients, and is not suitable for the later active training.

2. The metal wire in the rubber tube in the rehabilitation device is heavy and prone to fatigue, so it is not suitable for long-term use
