Portable multi-mode controlled hand function rehabilitation training device

Abstract

The invention relates to a portable multi-mode controlled hand function rehabilitation training device, wherein a four-fingered driving mechanism and a four-fingered reducing mechanism are arranged on a thumb plate; a thumb driving mechanism and a thumb reducing mechanism are arranged on the thumb plate; the four-fingered driving mechanism is connected with a connecting rod mechanism by the four-fingered reducing mechanism; the connecting rod mechanism is connected with a curved chute mechanism and a self-adaption finger adjusting mechanism; the curved chute mechanism is driven by the four-fingered driving mechanism, so that the movement of metacarpal joints and the movement of proximal phalangeal joints are realized; the thumb driving mechanism is connected with a thumb driving connecting rod mechanism by the thumb reducing mechanism; the driving connecting rod mechanism is connected to a thumb curved chute mechanism; the front end of the thumb curved chute mechanism is connected with a non-elastic bandage for thumbs; the thumb driving mechanism drives the thumb curved chute mechanism to prompt thumb joints to move. According to the portable multi-mode controlled hand function rehabilitation training device, two micro-motors are used for realizing single training of thumbs, and joint training and grabbing training of four fingers; the independent movements of thumb metacarpophalangeal joints, four-finger metacarpophalangeal joints and proximal phalangeal joints under a simple structure are realized.

Description

technical field [0001] The invention relates to a hand function rehabilitation training device, in particular to a portable device applied to hand rehabilitation training of stroke patients. Background technique [0002] In China, the standardized prevalence rate of stroke is about 1.82%. The number of stroke patients over the age of 40 is as high as 10.36 million, of which 85% suffer from upper limb functional defects. The factors of high degree of precision lead to the most difficult rehabilitation of hand function. [0003] The exoskeleton-type hand function rehabilitation training robots that have been clinically applied at home and abroad basically follow the route of medium and large-scale equipment, such as the Gloreha robot from IDROGENET in Italy, the ExoHand robot from FESTO in Germany, and the Hong Kong Polytechnic University. EMG drives the manipulator robot. Existing products significantly increase the volume of equipment within the patient's field of vision, ...

Problems solved by technology

[0004] At the same time, only large hospitals or rehabilitation centers will purchase such high-priced medium and large-scale equipment. Such equipment characteristics restrict patients to perform intermittent rehabilitation exercises at specified time and place, and the training volume cannot reach Patient's optimal recovery needs
