Multichannel electrical stimulation device based on myoelectricity feedback

Abstract

The invention discloses a multichannel electrical stimulation device based on myoelectricity feedback, and relates to the field of medical instruments. The device comprises a myoelectricity signal collection/electrical stimulation output instrument, an upper computer, and a signal collection/output part. The myoelectricity signal collection/electrical stimulation output instrument is in communication connection with the upper computer, and the myoelectricity signal collection/electrical stimulation output instrument and the signal collection/output part are connected with each other through a wire. The signal collection/output part is connected to a human body. The device integrates the myoelectricity diagnosis and the electrical stimulation treatment to form closed-loop control, so as to achieve the sharing of a myoelectricity diagnosis and electrical stimulation electrode in different time periods. The device is high in cooperation degree, is good in compatibility, is portable and is easy to use. The device achieves the purposes of clinical active rehabilitation, precise positioning and diagnosis and targeting simulation treatment.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a multi-channel electrical stimulation device based on myoelectric feedback. Background technique [0002] Electromyography (EMG) is a method of using electronic instruments to record the electrical activity of muscles at rest or contraction, and using electrical stimulation to examine nerve and muscle excitation and conduction functions. This examination enables the determination of the functional status of peripheral nerves, neurons, neuromuscular junctions, and the muscles themselves. [0003] Electrical stimulation for the human body refers to the use of low-frequency pulse currents of a certain intensity to stimulate one or more groups of muscles through a pre-set program. It was first used to correct the foot drop gait of hemiplegic patients. With the development of technology and research, from the initial functional electrical stimulation for the purpose of improving or re...

Problems solved by technology

[0006] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is that myoelectric diagnosis and electrical stimulation therapy are used independently, the compatibility is poor, and it is impossible or difficult to adjust the output of electrical stimulation therapy according to the muscle state of the affected side in real time to achieve active rehabilitation. Low, myoelectricity and electrical stimulation electrodes are not unified, it is impossible to accurately locate pathological muscle groups and enhance targeted stimulation, and the equipment is bulky; through the integration of myoelectricity diagnosis and electrical stimulation treatment to form a closed-loop control, to obtain myoelectricity diagnosis and electrical stimulation electrodes Time-sharing sharing with high degree of cooperation, good compatibility, portable and easy-to-use electrical stimulation device, clinically achieve the purpose of active rehabilitation, precise positioning and diagnosis, and targeted stimulation therapy
