Description

Electrode device for sustainable detection

The invention relates to an electrode device; in particular to an electrode device for sustainable detection, which can monitor the electrical signal of the skin or mucous membrane position of a patient at any time.

In the technology of the skin surface electrical signal, electrodiagnosis is a better example. It mainly uses the electrophysiological characteristics of nerves and muscles to stimulate the nerves with electrical current to record their movement and sensory response waves; or The needle pole records the electrophysiological activity of the muscle. To assist in the diagnosis of neuromuscular disorders. Myoelectric diagnostic tests basically consist of three parts: 1. nerve conduction studies 2. needle electromyography 3. evoked potentials. The above examinations can help diagnose the central nervous system, peripheral nerves and muscle diseases clinically. Especially for lower motor neurons, nerve roots, plexus, neuromuscular junction, and even various muscle abnormalities, nerve conduction tests and needle electromyography can help detect the nature of the disease (differentiating nerves Disease or muscle disease), location (nerve root, plexus, or peripheral neuropathy) and severity to assist in the correct clinical diagnosis, choice of treatment, and assessment of effects and prognosis. The following is a general introduction to the EMG diagnostic tests of nerve conduction tests: Nerve conduction tests use electrodes to stimulate the nerve to be tested, and record potentials on the sensory nerves or muscles that it controls to obtain sensory nerve action potentials and compound muscles. Inspection of meat action potential (compound muscle action potential) and special reflected potential waves (H-reflex and F-response). The test method is to use supramaximal stimulation to stimulate the tested nerve (except for H reflex) so that all axons of the nerve are excited at the same time to obtain a maximum response wave. According to the conduction latency of this maximum response wave ( Compared with normal values, latency, amplitude, surface area, and nerve conduction velocity can help distinguish between axonopathy or demyelination of nerves.

The conventional technology is mainly a set of surface electrodes attached to the surface of the human body to measure the potential changes of the muscle group. After calculation by the computer, various potential wave cycle charts are generated for an operator to read relevant physiological data, such as literature Journal-Clinical Neurophysiology 110 (1999) 2171-2175, and compared with 7 kinds of common surface electrodes. The main differences are in materials, disposables, and contact surface area. The results show that when the contact area is smaller, , The larger the resistance, the weaker the signal that can be read; In addition, the higher the close contact between the sensing area of the surface electrode and the area to be measured, the smaller the resistance, and the more the signal that can be read Strong, however, the above-mentioned conventional patch electrodes cannot be completely attached to the surface, which causes the signal to appear more confusing and cannot be effectively read, and most of them are disposable, which may easily cause the patient's medical burden. .
