Problems solved by technology

[0004] Through the analysis of the research status at home and abroad, it is found that the domestic ankle orthosis is usually driven by a motor, but the mechanical performance of the motor drive is high in rigidity and poor in flexibility. Disadvantages such as low cost, high price, and high dependence on physical therapists

Embodiment Construction

[0016] The present invention will be further described below in conjunction with drawings and embodiments.

[0017] Such as figure 1 , in view of the abnormal gait of stroke patients during walking and the requirements for safety and flexibility in rehabilitation training, artificial muscles with safety, energy saving, good flexibility and low price are selected as the drive design and production of the orthosis Pneumatic artificial muscle-driven ankle orthosis.

[0018] The mechanical device mainly consists of a pair of opposing artificial muscles, a joint shaft, a support rod, a horizontal frame and a foot. The artificial muscle used was made by the laboratory itself. The specific parameters are as follows: the inner diameter is 9 mm, the length is 31 cm, and when the air pressure is 0.35 MPa, the contraction amount is 8 cm, and the contraction rate is 25.8%. It is 58N.

[0019] Such as figure 2 , Ankle joint orthosis is divided into three parts: mechanical structure, p...

Abstract

Provided is a novel pneumatic artificial muscle-driven ankle orthosis instrument. A pair of opposing artificial muscles are adopted as drive elements and fixed to the ankle portion of the human body to conduct tracking exercise on an ankle gait curve in the normal walking state of a normal person, so that the purpose of exercise rehabilitation is achieved; besides, self-rehabilitation can be achieved with the help of a lower limb rehabilitation medical robot without physical therapists or medical workers. Compared with a traditional motor-driven orthosis instrument, the novel pneumatic artificial muscle-driven ankle orthosis instrument has the advantages of being good in flexibility, safe, capable of saving energy, low in price and the like, and has great practical value and market prospects.

Description

technical field [0001] The invention relates to a novel pneumatic artificial muscle-driven ankle joint corrector, which is suitable for the mechanical field. Background technique [0002] Stroke patients have problems such as lower limb muscle weakness, hypertonic spasms, motor control disorders, and deep and shallow sensory disturbances due to damage to upper motor neurons. As far as the ankle joint is concerned, patients are prone to abnormal walking patterns such as foot pronation, foot drop, circular dorsiflexion spasm, joint instability, reduced stride length, slow gait, and asymmetrical walking during walking. At present, neuromuscular facilitation, that is, exercise therapy, is the main treatment method for symptoms such as lower limb paralysis or hemiplegia caused by damage to human nerves. Orthotic treatment can improve post-stroke hemiplegia patients' ability to control their own posture, improve walking ability, control mild spasticity, prevent and correct deform...
