Problems solved by technology

However, its driving equipment has a complex structure, large volume, and heavy weight, which is very inconvenient for patients to carry, and reduces the ability of daily assistance and rehabilitation training
And it has limited athletic ability, poor controllability, and expensive
Equipment made of rigid materials can cause a poor fit between the hand and the functional rehabilitation mechanism, which affects not only the comfort of the patient when wearing it, but also the treatment effect
In addition, if the rigid connection structure produces a movement accident, it will lead to re-injury of the patient

Abstract

The invention discloses an intelligent flexible hand function rehabilitation glove based on a shape memory alloy. The glove comprises a flexible glove structure, a finger state monitoring system basedon a Hall sensor and a shape memory alloy driving system, and the flexible glove structure comprises an arm base, a support rod, a palm protection sleeve and finger sleeves; the finger state monitoring system based on the Hall sensor comprises the Hall sensor, magnetic steel and a feedback circuit. The shape memory alloy driving system comprises a shape memory alloy spring, a pull wire and a control unit. The monitoring system based on the Hall sensor is placed on each finger sleeve of the flexible glove structure and is fixedly connected through bonding, and the shape memory alloy driving system is located on the arm base of the flexible glove structure and is fixedly connected with the arm base through screws. The intelligent flexible hand function rehabilitation glove has the advantages of being high in flexibility, high in intelligent degree, light, easy to carry and the like, daily life of a patient suffering from hand dysfunction can be effectively assisted, and the hand function rehabilitation effect of the patient is improved.

Description

technical field [0001] The invention belongs to the technical field of medical rehabilitation equipment, and relates to hand function rehabilitation equipment, in particular to an intelligent flexible hand function rehabilitation glove based on a shape memory alloy, which can assist patients with hand dysfunction in daily life and at the same time play a role in rehabilitation training. Background technique [0002] Hands are a very important part of the human body. In people's daily life and work, hands are used very frequently, and their functions are irreplaceable. There are a large number of patients with hand dysfunction in life. Among them, stroke is the first cause of hand disorders in adults in my country, and it has the characteristics of high incidence, high disability rate, high mortality rate and high recurrence rate. According to statistics, 65% of patients will experience hand dysfunction. Hand dysfunction greatly reduces the independent living ability of pat...
