Multi-degree-of-freedom upper limb rehabilitation device

Abstract

The invention provides a multi-degree-of-freedom upper limb rehabilitation device. The multi-degree-of-freedom upper limb rehabilitation device mainly comprises a seat, a telescopic support, a shoulder rehabilitation assembly, an elbow rehabilitation assembly and a wrist rehabilitation assembly. The telescopic support is placed at the rear end of the seat, the shoulder rehabilitation assembly is fixed to the upper end of the telescopic support, the shoulder rehabilitation assembly and the elbow rehabilitation assembly are fixed through a bolt, the elbow rehabilitation assembly and the wrist rehabilitation assembly are in gear transmission, and the wrist rehabilitation assembly has three degrees of freedom, and is high in rigidity and good in precision. By controlling forward and reverse rotation of a motor, actions of inward retraction and outward swinging as well as forward bending and backward stretching of the shoulder, forward bending and backward stretching of the elbow and inwardrotation and outward rotation of the wrist can be achieved. The wrist drives a gear and a rack to be meshed through the control motor to adjust stretching and retracting of three branch chains, the actions of forward bending and backward stretching as well as inward retraction and outward stretching of the wrist can be completed, and multi-degree-of-freedom movement of the upper limb is achieved.The multi-degree-of-freedom upper limb rehabilitation device is high in practicability, good in economical efficiency and suitable for rehabilitation exercise of stroke hemiplegia patients and limb injury patients.

Description

technical field [0001] The invention relates to the field of rehabilitation machinery, in particular to a multi-degree-of-freedom upper limb rehabilitation device. Background technique [0002] With the aging of my country's social population, the number of elderly people in my country is constantly expanding, and the number of stroke patients is also increasing. Hemiplegia is the most common sequelae of stroke. Inability to move, this disease deeply affects people's daily life, and brings great pain to the patient's physiology and psychology. At the same time, with the development of society, in the process of human exploration, accidental injuries, including limb injuries, will inevitably occur. Whether it is hemiplegia caused by stroke or limb injuries caused by accidents, it will affect the daily life of patients. Life creates deep distress.

Problems solved by technology

[0003] The traditional way of rehabilitation training for patients mainly relies on professional nurses or physical therapists to carry out rehabilitation training for patients hand in hand. Due to the lack of professional rehabilitation trainers, it is also necessary to consider the patient's economic situation and whether they can afford high professional nursing expenses , so the effect of traditional rehabilitation training is not good
