Technical Field

The present invention relates to an electrode device; in particular to an electrode device capable of continuously detecting, which can monitor the electric signal of the skin or mucous membrane position on the surface of a patient at any time.

Background

Among the existing techniques of skin surface electrical signals, electromyography (electromyography) is a preferred example, which mainly uses the electrophysiological properties of nerves and muscles to record the reaction waves of movement and sensation by stimulating nerves with electric current; or recording the electrophysiological activity of the muscle with a needle. To assist in the examination of the diagnosis of neuromuscular disorders. Myoelectric diagnostic tests basically include three major components, 1. nerve conduction tests (nerve conduction students) 2. needle electromyography (needle electromyography)3. evoked potential tests (evoked potentials). The above examinations are clinically helpful for the diagnosis of central nervous, peripheral nervous and muscular diseases. In particular, for lower motor neurons, nerve roots, plexuses, neuromuscular junctions (neuromuscular junctions), and even various muscle abnormalities, nerve conduction tests and pin-point electromyography tests can help detect the nature (to distinguish between neuropathy or myopathy), location (nerve root, plexus, or peripheral neuropathy), and severity of the pathology to aid in accurate clinical diagnosis, selection of treatment, and assessment of outcome and prognosis. The following description is only made in a general way for myoelectric diagnostic tests of nerve conduction tests:

nerve conduction examination is an examination in which the nerve to be measured is stimulated with electrodes, and a potential is recorded on the sensory nerve or muscle innervated thereby to obtain a sensory nerve action potential wave (sensory nerve action potential), a compound muscle action potential wave (compound muscle action potential), and a specifically reflected potential wave (H-reflex and F-response). The examination method is to stimulate the tested nerve with super-large electric stimulation (except for H reflex) to excite all axons of the nerve at the same time to obtain a maximum response wave, and the axonal lesion (axonopathy) or myelin lesion (demyelination) of the nerve can be distinguished by comparing the conduction latency (latency), amplitude (amplitude), surface area (surface area) and conduction velocity (nerve continuity) of the maximum response wave with normal values.
