Ankle joint rehabilitation training device driven by pneumatic muscles for wheelchair

Abstract

The invention relates to an ankle joint rehabilitation training device driven by pneumatic muscles for a wheelchair. The ankle joint rehabilitation training device comprises an air pump, a pedal mechanism, a controller and the pneumatic artificial muscles, wherein, the pneumatic artificial muscles are independently connected with an air pump through air pipes, each air pipe is provided with a proportional control valve, the pedal mechanism is detachably installed on the wheelchair, and comprises a base and a pedal plate movably connected to the base, the pneumatic artificial muscles are independently connected with the pedal plate through sleeve steel ropes by means of a base and used for driving the pedal plate to do three activity forms of actions, and the controller is in communicationconnection with the air pump and all the proportional control valves. Compared with the prior art, the three activity forms of rehabilitation training actions of an ankle joint are realized on the wheelchair through the driving of the pneumatic artificial muscles, and the ankle joint rehabilitation training device is high in flexibility, more smooth in action, good in buffering performance, simplein structure, light in weight, resistant to dampness and high in environmental adaptability and can better promote the rehabilitation treatment effect and reduce secondary injuries, and the treatmentactions better fit the biological characteristics.

Description

technical field [0001] The invention relates to a training device, in particular to an ankle joint rehabilitation training device for a wheelchair driven by pneumatic muscles. Background technique [0002] Nowadays, with the aging of society and various congenital disabilities caused by environmental pollution, or with the continuous increase of traffic accidents, physical disabilities caused by accidents the day after tomorrow have become particularly serious. According to the data of the Second National Sample Survey on Disabled Persons, the total number of disabled people in my country is 82.96 million. If calculated on the basis of a family of three, on average, one out of every five families in my country has a disabled person. Among them, physical disabilities 24.12 million people, accounting for about 30% of the disabled. It has become an urgent social problem to provide treatment and rehabilitation training for this huge number of disabled people to help them return ...

Problems solved by technology

Unfortunately, the CPM training time of existing hospitals and other rehabilitation institutions is only 15-30 minutes, so the amount of exercise is far from enough

Although many ankle joint rehabilitation training devices have been developed in the market, most of them are driven by rigid actuators such as motors. It is suitable for use on wheelchairs, etc., which restricts the use of the equipment. Many shortcomings reduce the curative effect of rehabilitation and limit its use environment
