Abstract
The invention relates to ECG (electroglottograph) measuring method and device for vocal cords. The method includes the steps of firstly, coating the surface of an electrode plate to obtain a contact layer; secondly, tightly attaching the electrode plate to a vocal cord position on a neck; thirdly, fixing the electrode plate, allowing a testee to make voice, and outputting vocal cord signals from an audio output end after being processed by the electrode plate and the ECG measuring device. 2MHz signals are applied to thyroid cartilage to apply high frequency excitation to a throat so as to eliminate external interference from myoelectricity, a microphone and the like. The signals of the electrode are measured and are subjected to bandpass filtering, a detecting circuit and bandpass filtering to obtain corresponding impedance changes. Vocal cord vibration is reflected by contacting the electrode with throat and measuring electrical characteristic changes of a volume conductor at the throat. The modes of the vocal cord vibrations can be measured objectively, quantitatively and directly without invasion.
Description
Technical field
The present invention relates to a kind of measuring technique of vocal cords, especially a kind of electric glottogram measuring method and device thereof of vocal cords.
Background technology
Vocal cords are subject to damage and the key position that pathological changes takes place in the phonatory organ.The vocal cord vibration measurement is the cross point of area researches such as laryngopathy diagnosis and treatment, art voice, language and linguistic science.Electroacoustic door diagram technology is used for voice, the sampling of larynx glottis electrograph, measures the vocal cord vibration pattern.
The method that is adopted in the existing vocal cords measuring technique is to utilize high-speed photographing method, is about to detecting devices and directly stretches in measured's the throat, through the figure signal that detecting devices detected vocal cords is detected.But this method has limited promoting the use of of it to the invasive of sounding with expensive cost.Various laryngoscopes and laryngostroboscope have also disturbed the condition of sounding, and the information of objective quantitative can not be provided.Test and analysis to oral cavity air-flow and voice signal can not directly reflect the vocal cord vibration characteristic.
Summary of the invention
The technical problem that the present invention will solve is: propose a kind of do not have invasive, objective, quantitatively and directly measure the electric glottogram measuring method and the device thereof of vocal cord vibration pattern.
The technical scheme that the present invention adopted is: a kind of electric glottogram measuring method of vocal cords may further comprise the steps:
1) applies contact layer at electrode plate surface;
2) battery lead plate is close to the vocal cords place of neck;
3) behind the position of fixed plate electrode, by measured's pronunciation, vocal cord signal is handled the back by battery lead plate through electric glottogram measuring device and is exported from audio output.
Specifically, be on the metal surface of battery lead plate, to be coated with wet or to be coated with the very thin water miscible electrode gel of one deck in the step 1) of the present invention with saline; The number of described battery lead plate is two.
During test, cling to two battery lead plate branch left and right sides on the neck, make them be in the thyroid cartilage position at 7 ~ 8mm place, neck front; After battery lead plate is adjusted to the optimum position,, guarantee that electrode all is adjacent to skin all the time fully by the position of testee with thumb and forefinger fixed plate electrode.Apply the signal of 2MHz in the thyroid cartilage position.
Simultaneously; The present invention also provides a kind of electric glottogram measuring device of vocal cords; Comprise the sustained oscillation device, the outfan of described sustained oscillation device connects the input isolating transformer, and isolating transformer is through surveying the signal of larynx vocal cords behind the impedor; And be transferred to another isolating transformer, the outfan connecting band bandpass filter of this isolating transformer; Described band filter is exported signal successively through connecting audio frequency behind detecting circuit, amplifying circuit and another band filter again.
Further say the signal of the input input 2MHz of sustained oscillation device of the present invention.
Operation principle of the present invention is: the signal that applies 2MHz at thyroid cartilage; With this larynx is applied high frequency pumping, eliminate external interference such as myoelectricity, mike, then the signal of measurement electrode; Through bandpass filtering-detecting circuit-bandpass filtering, obtain corresponding impedance variation.
The invention has the beneficial effects as follows: the present invention utilizes electrode to contact with throat, reflects vocal cord vibration through measuring throat's volume conductor electrical property change, can not have invasive, objective, quantitatively and directly measure the vocal cord vibration pattern.
