Embodiment Construction

[0025] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0026] Such as Figure 9 The electroglottogram measurement device of the vocal cords shown includes a constant-amplitude oscillator, the output of the constant-amplitude oscillator is connected to an input isolation transformer, and the input isolation transformer passes through an impedance and then transmits the signal for detecting the vocal cords of the larynx to another isolation transformer , the output end of the isolation transformer is connected to a band-pass filter; the band-pass filter passes the signal through the detection circuit, the amplifier circuit and another band-pass filter in turn, and then connects to...

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 [0001] The invention relates to a vocal cord measurement technique, in particular to a vocal cord electroglottogram measurement method and a device thereof. Background technique [0002] The vocal cords are the key parts of the vocal organs that are most vulnerable to damage and lesions. Vocal fold vibration measurement is an intersection of research in the fields of diagnosis and treatment of laryngopathy, artistic voice, language and language science. Electroglottography is used for vocal and larynx electroglottogram sampling to measure vocal cord vibration patterns. [0003] The method adopted in the existing vocal cord measurement technology is to use high-speed photography, that is, the detection device is directly inserted into the throat of the subject, and the vocal cord is detected by the graphic signal detected by the detection device. However, the invasiveness and high cost of this method limit its popularization. Various laryngoscopes and laryn...
