Elbow joint flexion and extension rehabilitation training device

Abstract

The invention discloses an elbow joint flexion and extension rehabilitation training device which comprises a forearm fixing assembly, a big arm fixing assembly and a motor fixedly arranged on the bigarm fixing assembly. A static torque sensor is fixedly arranged on the forearm fixing assembly; the static torque sensor is movably connected to the big arm fixing assembly through a transmission mechanism. The static torque sensor is in a stepped shaft shape and sequentially comprises an input flange shaft, a middle transmission shaft and an output square shaft. The middle transmission shaft issleeved with a first shaft sleeve fixedly arranged on the big arm fixing assembly. The output square shaft is sleeved with a second shaft sleeve fixedly arranged on the forearm fixing assembly. The small arm fixing assembly is provided with a limiting switch for limiting the small arm fixing assembly, the motor is provided with a position code for detecting the rotating position of the small arm fixing assembly. The device is compact in structure, simple in appearance, small in number of parts, capable of greatly saving the machining cost and good in market popularization prospect.

Description

technical field [0001] The invention relates to the technical field of rehabilitation medicine, in particular to an elbow joint flexion and extension rehabilitation training device. Background technique [0002] After the onset of stroke, most of them are accompanied by hemiplegia symptoms. After the onset, there is a disability rate of about 75%. It is also the most common cause of death in the world. Most patients lose the ability to move their limbs, which brings great pain to the lives of patients. And inconvenience, but also increased the burden and pressure for the family and the country. The traditional means of rehabilitation mainly rely on the one-on-one service of rehabilitation physicians, and there are 70 million stroke patients in my country, and the number of rehabilitation physicians is seriously insufficient. The affected side of the upper limb of the hemiplegic patient is in a flexed posture, which seriously affects the daily life of the patient. Therefore,...
