Problems solved by technology

[0004] However, in the prior art, the acquisition and analysis of EMG signals and the control of neuromuscular electrical stimulation have the defects of signal delay and poor precision.
At the same time, when it is necessary to perform neuromuscular electrical stimulation and myoelectric signal collection on a certain muscle group of the human body, it is usually necessary to stick two pairs of electrodes on the human skin of the corresponding muscle group and connect two sets of wires to perform neuromuscular electrical stimulation and muscle electrical stimulation respectively. Electrical signal acquisition, high cost and poor convenience

Abstract

The invention relates to a myoelectric signal collector and a rehabilitation system. The collector comprises a main control chip which is used for controlling the transmission of a signal on the myoelectric signal collector; a control circuit which is electrically connected with the output end of the main control chip and is used for controlling working states of a myoelectric collection circuit and a neuromuscular electrical stimulation circuit according to a control signal sent by the main control chip; the myoelectric collection circuit which is used for collecting a muscle group signal ofa target muscle group through an electrode slice electrically connected with an electrostatic protection circuit; and the neuromuscular electrical stimulation circuit which is used for performing low-frequency stimulation on the target muscle group through the electrode slice electrically connected with the electrostatic protection circuit. According to the invention, the myoelectric signal collection precision and the neuromuscular electrical stimulation precision of the muscle group can be improved, measurement errors and time delay are reduced and shortened, and actual application requirements are met.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a myoelectric signal collector and a rehabilitation system. Background technique [0002] Surface electromyographic signal is the electric conduction of a large number of nerve fibers and muscle fibers in the process of human muscle movement, and the resulting large amount of ion movement in the body fluid produces electrical changes that reflect to the body surface, and can reflect the functions of nerves and muscles to a certain extent. state. When a movement disorder occurs in a limb, one form of rehabilitation training is to measure the EMG signal of the muscle / muscle group that causes the movement disorder, analyze the collected EMG signal, and perform neuromuscular electrical stimulation on the corresponding muscle / muscle group. In order to adjust the intensity of neuromuscular electrical stimulation according to the current myoelectric signal. [0003] As we all know...
