Detection device for detecting genioglossus muscle function by means of mandible surface electromyography

Abstract

The invention discloses a detection device for detecting the genioglossus muscle function by means of mandible surface electromyography. The detection device comprises at least three collection electrodes for collecting surface electromyography signals, wherein the surface of each collection electrode is coated with at least one nanometer silver non-woven fabric layer. Nanometer silver fibers are adopted as the dry electrodes, the conductive paste consumption is lowered, the polarization electromotive force is small, application is more convenient and rapider, the good electromyography guiding effect can be obtained, the collected electromyography signals are more comprehensive and accurate, and the detection device can not only be applied to human body mandible surface electromyography detection and but also be used for surface electromyography detection of the other portions of the body.

Description

technical field [0001] The invention relates to the field of biomedical engineering, in particular to a detection device for detecting the function of the genioglossus muscle by using the mandibular surface myoelectricity. Background technique [0002] Electromyography (Electromyography, EMG) is the curve of electrical activity recorded by electronic instruments when muscles are at rest or contracting; the action potential of a muscle fiber forms a Single Fiber Action Potential (SFAP) during the propagation process; a movement The superposition of all SFAPs in the unit in time and space forms the motor unit action potential (Motor Unit Action Potential, MUAP) (Peter, 2005); the motor unit action potential sequence (Motor Unit Action Potential train, MUAPt) is generated during the continuous discharge of the motor unit ); during muscle activity, the MUAPt formed by multiple motor units involved in muscle activity is filtered by volume conductors composed of muscle, subcutaneo...

Problems solved by technology

[0017] The technical problem to be solved by the present invention is to provide a detection device that utilizes mandibular surface electromyography to detect the function of the genioglossus muscle, so as to solve the problem that the electrodes themselves used in the electromyography detection process are susceptible to noise interference, myoelectricity, etc. The signal is easy to attenuate during the propagation process, the acquisition and processing of the surface electromyographic signal is difficult, and the use of conductive paste leads to changes in the performance of the conductive medium, which affects the quality of the collection, etc.
