Electrode measurement device based on electromyographic signals of genioglossus muscle

Abstract

The invention discloses an electrode measurement device based on electromyographic signals of a genioglossus muscle. The electrode measurement device comprises a low jaw support, a reference electrode and array collection electrodes arranged in two rows and at least two lines, wherein the low jaw support is used for fixing the electrodes distributed on the low jaw support, the reference electrode is arranged in the middle of the upper portion of the lower jaw support and corresponds to the middle combination portion of the two side portions of the lower jawbone of a human body, and the array collection electrodes are sequentially arranged on the two sides of the lower portion of the reference electrode and correspond to the lower jaw tongue muscles of the human body. Compared with the prior art, the multi-electrode array measurement mode is adopted, the electrodes are large in number and wide in distribution range, the space resolution is high, the resolution ratio of the electromyographic signals of the genioglossus muscle can be increased, the electrodes are made of silver wire non-woven fabric fibers, the electrical resistivity is low, the polarized electromotive force is small, and the electrode measurement device is comfortable to wear.

Description

technical field [0001] The invention relates to the field of biomedical engineering, in particular to an electrode measuring device based on genioglossus myoelectric signals. Background technique [0002] Genioglossus Muscle (GGM) is an important dilator muscle of the pharynx. Increased activity can make the tongue protrude, expand the space behind the tongue, and expand the upper airway. The base of the tongue falls back, which is caused by the weakened tone of the genioglossus muscle. It is currently believed that the narrowing of the throat airway caused by it is the main cause of Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS). At present, there are many reports on the bioelectric activity research methods of the genioglossus muscle, including needle-like electrodes, wire-like electrodes and hook-like electrodes. Small, but easily affected by the patient's saliva and oral temperature, and can interfere with the patient's sleep. In the process of obstructive apnea hyp...
