Abstract
The utility model relates to an electroglottography measuring device of vocal cords. The electroglottography measuring device of vocal cords comprises a vibrator in uniform amplitude. The output end of the vibrator in uniform amplitude is connected with an input isolation transformer. The isolation transformer detects the signals of the throat vocal cords through an impedor and transfers the signals to another isolation transformer with the output end connected with a band-pass filter. The band-pass filter consequently transfers the signals through a detector circuit, an amplifying circuit and another band-pass filter and then connects the audio output. The electroglottography measuring device of vocal cords utilizes an electrode to contact the throat and reflects the vibration of the vocal cords through measuring the character change of throat volume conductor electricity. The electroglottography measuring device of vocal cords has the advantages of being free of invading, objective, quantitative and direct measurement of vibrating module of vocal cords.
Description
Technical field
This utility model relates to a kind of measuring device of vocal cords, especially a kind of ElectroglottographicWaveform measuring device of vocal cords.
Background technology
Vocal cords are subject to damage and the key position of pathological changes occurs in the phonatory organ.The vocal cord vibration measurement is the cross point of the area researches such as laryngopathy diagnosis and treatment, art voice, language and linguistic science.The ElectroglottographicWaveform technology is used for voice, the sampling of larynx glottis electrograph, measures the vocal cord vibration pattern.
The method that adopts 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, and the figure signal that detects by detecting devices detects vocal cords.But this method has limited promoting the use of of it to invasive and the expensive cost of sounding.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.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of without invasive, objective, quantitatively and directly measure the ElectroglottographicWaveform measuring device of vocal cord vibration pattern.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of ElectroglottographicWaveform measuring device of vocal cords, comprise the sustained oscillation device, the outfan of described sustained oscillation device connects the input isolating transformer, isolating transformer is by 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 by connecting again audio frequency behind detecting circuit, amplifying circuit and another band filter.
Further, the signal of the input of sustained oscillation device described in the utility model input 2MHz.
Measuring method of the present utility model is as follows:
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 exported from audio output after being processed through the ElectroglottographicWaveform measuring device by battery lead plate.
Specifically, be on the metal surface of battery lead plate, to be coated with wet with saline or to be coated with the very thin water miscible electrode gel of one deck in the step 1) described in the utility model; The number of described battery lead plate is two.
During test, two battery lead plate minute left and right sides are clung 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, by the position of testee with thumb and forefinger fixed plate electrode, guarantee that electrode all is adjacent to skin all the time fully.Apply the signal of 2MHz in the thyroid cartilage position.
Operation principle of the present utility model is: the signal that applies 2MHz at thyroid cartilage, with this larynx is applied high frequency pumping, eliminate the external interference such as myoelectricity, mike, then the signal of measurement electrode, through bandpass filtering-〉 detecting circuit-〉 bandpass filtering, obtain corresponding impedance variation.
The beneficial effects of the utility model are, solved the defective that exists in the background technology, this utility model utilizes electrode to contact with throat, reflects vocal cord vibration by measuring throat's volume conductor electrical property change, can without invasive, objective, quantitatively and directly measure the vocal cord vibration pattern.

The specific embodiment
With preferred embodiment this utility model is described in further detail by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with this utility model.
The ElectroglottographicWaveform measuring device of a kind of vocal cords as shown in Figure 9, comprise the sustained oscillation device, the outfan of sustained oscillation device connects the input isolating transformer, the signal that the input isolating transformer is surveyed the larynx vocal cords after by impedor is transferred to another isolating transformer, the outfan connecting band bandpass filter of this isolating transformer; Band filter is exported signal successively by connecting again audio frequency behind detecting circuit, amplifying circuit and another band filter.
Total mainboard structure circuit diagram as shown in Figure 2.Comprising sustained oscillation device, isolating transformer, impedor, band filter, detecting circuit, amplifying circuit, shown in Fig. 3 ~ 8 is the circuit theory diagrams of these unit.In other embodiments, sustained oscillation device, isolating transformer, impedor, band filter, detecting circuit, amplifying circuit can replace with the circuit of identical function, still can realize identical effect.
During measurement, at first on the metal surface of two battery lead plates, be coated with wet with saline or be coated with the very thin water miscible electrode gel of one deck; Then two battery lead plate minute left and right sides are clung on the neck, make them be in the thyroid cartilage position at 7mm place, neck front; After battery lead plate is adjusted to the optimum position, by the position of testee with thumb and forefinger fixed plate electrode, guarantee that electrode all is adjacent to skin all the time fully; Send a(Ah by the measured at last) sound, vocal cord signal is exported from audio output after being processed through the ElectroglottographicWaveform measuring device by battery lead plate.In the test process of reality, measured's pronunciation can be sent different sounds as required.
What describe in the above description is the specific embodiment of the present utility model, various not illustrating is construed as limiting flesh and blood of the present utility model, the person of an ordinary skill in the technical field after having read description can to before the described specific embodiment make an amendment or be out of shape, and do not deviate from essence and the scope of utility model.
