Abstract

The invention discloses an electrode measuring device based on the genioglossus myoelectric signal, comprising: a mandibular support for fixing electrodes distributed on it; The joint site in the middle of the body on both sides of the bone; the array-type acquisition electrodes composed of two columns and at least two rows are located on both sides of the lower part of the reference electrode in turn, corresponding to the mandibular glossus muscle of the human body. Compared with the prior art, the present invention adopts a multi-electrode array measurement method, has a large number of electrodes, a wide distribution range, and high spatial resolution, which can improve the resolution of bioelectric signals of the genioglossus muscle. The electrodes are made of silver non-woven fibers , low resistivity, small polarization electromotive force, and 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...
