Non-invasive neuromuscular disease inspection system based on attached electrode

Abstract

The invention discloses a non-invasive neuromuscular disease inspection system based on an attached electrode, and belongs to the field of a medical apparatus. The system comprises a surface electrode collecting device, a surface electrical stimulation device and a control terminal, wherein the surface electrode collecting device comprises an attached electrode I, a signal processing module, a communication module I and a power supply I; the attached electrode I collects a human physiological signal and transmits the signal to the signal processing module; the signal processing module processes the signal and then transmits the signal to the control terminal through the communication module I; the surface electric simulation device comprises an attached electrode II, a stimulating signal generation module, a communication module II and a power supply II; and the stimulating signal generation module receives a control signal transmitted by the control terminal through the communication module II, then generates an electric stimulating signal, and carries out electric stimulation on the human surface through the attached electrode II. Great pain on a sufferer caused by a needle electrode is overcome by the system; and a portable non-invasive detection method is provided for neuromuscular diseases such as amyotrophy and motor neuron disease.

Description

technical field [0001] The invention belongs to the field of nerve electrophysiological examination instruments, and relates to a non-invasive neuromuscular disease examination system based on an attached electrode. Background technique [0002] Nerve electrophysiological examination is an extension of nervous system examination. It mainly tests electromyography (electromyography, EMG), nerve conduction velocity (NCV), repetitive nerve stimulation (repetitive nerve stimulation, RNS). functional status. Nerve electrophysiological examination plays a key role in the diagnosis and evaluation of nerve and muscle lesions, and is also one of the important contents and means of rehabilitation assessment. [0003] Electromyography is to record the muscle potential changes in the three states of rest, light contraction, and heavy contraction, and display it on the monitor or recording paper for the operator's reference to help determine whether the disease is neurogenic or myogenic....

AI Technical Summary

Problems solved by technology

However, this device is easily affected by power frequency interference, and the signal-to-noise ratio of the collected signal is very low

However, it uses needle electrodes to penetrate the muscle belly to collect EMG signals. The operator needs to rotate repeatedly in the muscle belly, which brings unbearable pain to the subjects.

[0005] Chinese patent CN102626309 discloses a high-field magnetic resonance compatible electrode for neurophysiological monitoring in books. The needle-shaped electrode is composed of a needle-shaped head, a handle, a wire and a plug, which solves the problem that conventional electrodes are affected by high-field-strength magnetic fields. and thermal and displacement effects

Existing surface electromyography detection devices affect the signal-to-noise ratio and portability, and cannot work synchronously with stimulation devices
