Forearm rotation training biofeedback device

Abstract

A forearm rotation training biofeedback device comprises a bottom plate. A rotating rod is rotationally connected to the rear side of the left part of the bottom plate, a first gear is connected to the upper end of the rotating rod by a bevel gear set, a first transmission shaft is arranged on the front side of the first gear, a first incomplete gear is fixedly connected to the left side of the first transmission shaft, a second incomplete gear is arranged on the rear side of the middle part of the first incomplete gear, and an extension spring is connected between the first incomplete gear and the second incomplete gear. The problems that manpower and material resources are consumed in existing manpower-assisted forearm rehabilitation training of patients, the patients cannot conduct forearm rehabilitation training independently instead of manpower assisted forearm rotation rehabilitation exercise, and the existing device has single function and cannot control forearm rotation amplitude or maintain rotation in the forearm rotation amplitude for a period of time; and during forearm pronation or supination of the patients, the biofeedback device is lacking within the time of maintenance required when the forearm moves to the end of the set amplitude are solved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a forearm rotation training biofeedback device. Background technique [0002] At present, after the upper limb is injured, the motor function of the forearm is limited. The patient will have poor rotation of the forearm, which is generally dominated by external rotation. The forearm will have interosseous muscle and myofascial adhesion, which will further affect its function. Manually assisting patients to perform forearm rehabilitation training consumes manpower and material resources. It cannot replace artificially assisting patients with forearm rotation rehabilitation exercises, allowing patients to perform forearm rehabilitation training independently. The existing device has a single function and cannot control the forearm rotation range and within the forearm rotation range Hold one end time; when the patient’s forearm is pronated or supinated, and the movement reaches the e...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies of the prior art, the present invention provides a biofeedback device for forearm rotation training, which effectively solves the problem that the existing artificially assisted patients perform forearm rehabilitation training. For forearm rehabilitation training, the existing device has a single function and cannot control the range of forearm rotation and the time to maintain one end within the range of forearm rotation; when the patient's forearm is pronated or supinated, the time required to maintain the end of the set range Inside, there is no problem with biofeedback devices
