Detection device for detecting genioglossus muscle function by mandibular surface electromyography

Abstract

The invention discloses a detection device for detecting the function of the genioglossus muscle by using mandibular surface electromyography, comprising at least three collection electrodes for collecting surface electromyography signals, wherein the surface of the collection electrodes is covered with at least one layer of nanometer Silver thread non-woven fiber. The invention uses nano-silver fibers to make dry electrodes, reduces the use of conductive paste, has a small polarization electromotive force, is more convenient and quick to apply, and can achieve better myoelectric guidance effect, and the collected myoelectric signals are more comprehensive and accurate, not only It can be applied to the surface myoelectricity detection of the human jaw, and can also be used for the surface myoelectricity detection of other parts 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 a 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 motor unit The superposition of all SFAPs 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, subcutaneous tissue and...

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.
