Household cable-controlled upper limb rehabilitation training mechanical arm

Abstract

The invention relates to a household type cable controlled upper limb rehabilitation training mechanical arm, an elbow joint is rotatably connected with an upper arm rod through an elbow joint clamp,a shoulder joint is rotatably connected with a transition plate through a shoulder joint axis; the elbow joint clamp is internally provided with an elbow wheel I, the elbow wheel I is connected with an elbow bending / stretching motor through a steel wire rope sleeved with a line pipe so as to bend / stretch the elbow joint; a shoulder bending and stretching wheel I is connected on the transition plate through the shoulder joint axis and is installed at the tail end of the upper arm rod, a shoulder bending / stretching motor passes through a shoulder bending and stretching wheel II, the steel wire rope sleeved with the line pipe is in transmission connection with the shoulder bending and stretching wheel I through the transition plate to bend / stretch the shoulder joint; the transition plate is connected with a shoulder folding and unfolding transmission plate through a shoulder internal folding and external unfolding shaft, the bottom part of the shoulder folding and unfolding transmission plate is fixedly connected with a belt pulley II, a shoulder internal folding and external unfolding motor and a belt pulley I are installed on a bottom plate, the shoulder internal folding and external unfolding motor is in belt transmission with the belt pulley II on the shoulder folding and unfolding transmission plate through the belt pulley I and a transmission belt, and the shoulder joint isinternally folded and externally unfolded.

Description

technical field [0001] The invention relates to a home-use upper limb dysfunction rehabilitation training device, in particular to a mechanical arm mainly used for rehabilitation training of upper limb dysfunction (including upper limb functional nerve rehabilitation) caused by stroke; it can also be used for cerebral palsy, trauma, diabetes Rehabilitation training for upper limb dysfunction caused by etc. Background technique [0002] Stroke is one of the main diseases that threaten human physical and mental health and life safety. With the aggravation of aging, the incidence of cerebrovascular accidents or strokes is also increasing, of which hemiplegia and loss of walking ability are the most important. sequelae. According to the survey, 85% of stroke patients are accompanied by upper limb dysfunction in the early stage of the onset, and 55%-75% are still accompanied by upper limb dysfunction 3-6 months after the onset. It has become a problem to study the recovery of up...
