Upper limb rehabilitation device

Abstract

The invention discloses an upper limb rehabilitation device, and belongs to the field of medical rehabilitation training equipment. The device comprises two symmetrically arranged training rails arranged on the left side and the right side of a seat, and the training rails are connected to armrests of the seat through connecting supports; each training rail is an arc in the vertical plane, the front ends of the training rails are located right ahead the middle of a cushion, the rear ends of the training rails are located above the sides where the rear ends of the armrests on the correspondingsides of the seat are located, the heights of the front ends of the two training rails from the ground are different, and the positions of the front ends of the two training rails cross each other; holding sliding blocks moving along the rails are arranged on the training rails, and fixed parts binding palms of a user are arranged on the holding sliding block mechanisms; second sliding rails allowing a positive and negative rotating motor and a support component thereof to slide are arranged on one sides of the raining rails; the lower ends of the connecting supports are rotationally connectedto the armrests on the corresponding sides, and limiting blocks fixed to the armrests are arranged on the portions, facing the inner side of the seat, of the joints. Accordingly, comprehensive movement of the whole arm can be achieved, cooperation among joints is natural, and drive control is extremely easy.

Description

technical field [0001] The invention relates to the field of medical rehabilitation training equipment, in particular to an upper limb rehabilitation device. Background technique [0002] With the continuous development of medical technology, rehabilitation therapy has become a new treatment discipline to promote the physical and mental function recovery of patients and disabled people, and it is also a new technical specialty. Its purpose is to enable people to restore their daily production, study, work and labor, and social life abilities as much as possible, integrate into society, and improve their quality of life. Patients with upper limb loss of mobility and muscle atrophy due to cerebrovascular disease, traumatic brain injury and other causes often use external force passive exercise for rehabilitation training to help patients recover upper limb strength. [0003] At present, the more advanced upper limb rehabilitation device in the prior art is a mechanical arm st...

Problems solved by technology

However, it has the following disadvantages: when the upper limbs of the human body move normally, multiple joints are often required to cooperate, and the above-mentioned robot has a complicated structure and many driving components, and the driving of the shoulder joint is particularly cumbersome; it is difficult to control when the joints are coordinated.
