Hand exercise rehabilitation training and evaluation system based on flexible robot

Abstract

The invention provides a hand exercise rehabilitation training and evaluation system based on a flexible robot. The system comprises a flexible robot part, a control part and an information display part, wherein the flexible robot part comprises a flexible glove, a bending sensor, a posture sensor and the like, is used for driving the human hand to carry out rehabilitation training, and various exercise data in the training process is recorded in real time, so that data support is provided for the rehabilitation evaluating of patients; the control part mainly comprises a miniature multipath air valve, a miniature air pump and an electric regulating valve, through the synergism and coordination among the miniature multipath air valve, the miniature air pump and the electric regulating valve, the accurate control over the different bending angles and motion speeds of the flexible fingers is realized; and the information display part comprises a touch screen and function buttons, the system realizes interaction with a patient through the display part, so that the enthusiasm for rehabilitation training of the patient is fully aroused, and then the rehabilitation training effect is improved. For the system, the accurate control over the hand exercise rehabilitation is realized based on the flexible robot, the operation is simple and reliable, the price is low, the size is small, themaintenance is easy, and the system is particularly suitable for use by the patient at home.

Description

technical field [0001] The invention relates to the field of medical rehabilitation, in particular to a hand movement rehabilitation training and evaluation system based on soft robots. Background technique [0002] With the development of Chinese society, the problem of population aging in China is becoming more and more serious. Hand injuries are the most common after-stroke sequelae. Therefore, hand rehabilitation is an important part of the field of medical rehabilitation. The status of hands in the human body is self-evident. Hands allow people to complete a variety of delicate tasks, but many hemiplegia patients and stroke patients cannot control the free movement of their fingers. The work of rehabilitation and medical treatment for fingers is urgent, and a kind of effective and comfortable finger rehabilitation can be produced. Training equipment is even more urgently needed.

Problems solved by technology

[0002] With the development of Chinese society, the problem of population aging in China is becoming more and more serious. Hand injuries are the most common after-stroke sequelae. Therefore, hand rehabilitation is an important part of the field of medical rehabilitation. The status of hands in the human body is self-evident. Hands allow people to complete a variety of delicate tasks, but many hemiplegia patients and stroke patients cannot control the free movement of their fingers. The work of rehabilitation and medical treatment for fingers is urgent, and a kind of effective and comfortable finger rehabilitation can be produced. There is an urgent need for training equipment

[0003] Most of the current finger rehabilitation training devices use rigid-body manipulators, which themselves are also driven by mechanical rigid bodies. An existing single-degree-of-freedom rehabilitation manipulator drive device (Chinese invention patent CN106272404A) is driven by ropes, and the gears are meshed with each other. Its noisy, discontinuous and inflexible actuation fingers reduce the intended function and effectiveness of the device

[0004] At present, there are few devices for finger rehabilitation training using soft materials. There is an existing EMG-controlled pneumatic software rehabilitation manipulator (Chinese invention patent CN106309083A), whose fingers are made of soft materials and have the characteristics of low stiffness and high comfort. But it can only make the patient's fingers move blindly, and the bending angle of the fingers cannot be freely controlled. The rehabilitation trainer cannot carry out targeted training, and the rehabilitation treatment effect of the patient's fingers is not good.
