Pneumatic joint-type rehabilitation manipulator

Abstract

The invention provides a pneumatic joint-type rehabilitation manipulator. A pneumatic joint (2) is of a retractable pleated airbag structure; a wrist air inflation and deflation part (11) is communicated with the airbag structure of the pneumatic joint (2); a finger part (13) is matched with a connection structure of the hand bone, and a plurality of knuckle parts (131) on the finger part (13) aresequentially and rotatably connected and rotatably connected to a palm part (12) separately; the knuckle parts (131) are driven to rotate through the extension and retraction of the pneumatic joint (2) and provided with a wearing structure (3) for fixing the human hand. The pneumatic joint-type rehabilitation manipulator is suitable for training of patients with hand diseases in various occasionsespecially at home, helps the patients with the hand diseases to carry out correction rehabilitation training and is suitable for not only rehabilitation persons who cannot conduct active training with the hands and but also users who can carry out active training to a certain degree. The manipulator is simple in structure, convenient to manufacture and carry, easy to operate, economical and practical and has good market prospects.

Description

technical field [0001] The invention relates to the technical field of rehabilitation mechanical equipment, in particular to a pneumatic articulated rehabilitation manipulator. Background technique [0002] At present, the number of patients with hand disabilities caused by stroke, cerebral hemorrhage, cerebral infarction, cerebral thrombosis, cerebral palsy, burns, scalds and other accidents in China is gradually increasing every year. Its symptoms are mostly manifested as hand twitching, spasm, weakness in grasping, inability to stretch normally, and "hawk hook hands". [0003] Hand rehabilitation needs to be done step by step.
