Joint movement assistor

Abstract

The invention relates to a joint movement assistor, according to the technical scheme, a first joint part, a second joint part, a third joint part and a metacarpal bone part are sequentially fixed tothe back face of a soft glove from top to bottom; paper folding actuators are respectively arranged between the first joint part and the second joint part, between the second joint part and the thirdjoint part, and between the third joint part and the metacarpal bone part; an air pump comprises an air pump body and an inflation pipe. The paper folding actuator is provided with an inflation cavity, and the paper folding actuator achieves telescopic movement through inflation and deflation operation of the inflation cavity; the first joint part, the second joint part, the third joint part and the metacarpal bone part are communicated with the inflation cavity; an air inlet is formed in the end, away from the third joint component, of the metacarpal bone part. The air pump body communicateswith the air inlet through the inflation pipe. The hand can be promoted to complete joint flexion and extension movement without the help of other people, and the treatment difficulty and the treatment cost are reduced while the treatment effect is effectively guaranteed.

Description

technical field [0001] The invention relates to the field of sports equipment and rehabilitation equipment, in particular to a joint motion assisting device. Background technique [0002] Stroke has the characteristics of high morbidity, high mortality and high disability rate. According to statistics, there are about 15 million stroke patients in China. At present, stroke is one of the main causes of hand function failure. After stroke, patients may experience a variety of neurological deficit symptoms, among which hemiplegia and movement disorders are the most common, which are specifically manifested in the excessive activation of flexor muscles and insufficient strength between antagonistic muscle groups. The hand and wrist are always in flexion due to balance, resulting in inability to extend the fingers and wrist. [0003] At present, the improvement and rehabilitation treatment methods for the impaired motor function of hand hemiplegia caused by stroke in China are ...

Problems solved by technology

In the related art, the therapist generally adopts one-on-one rehabilitation therapy for the patient, which is not only labor-intensive and expensive, but also difficult to guarantee the training efficiency and intensity.

However, with the development of society and the continuous improvement of people's living standards, patients have higher and higher requirements and demands for hand function rehabilitation. This artificial one-to-one treatment method is difficult to meet people's needs.
