Abstract
An acoustic esophagus examining instrument for detecting the exception on esophagus wall has a group of acoustic transducers for acquiring the acoustic characteristics when a fluid flows through esophagus, including the audio signals and the time taken by each acoustic transducer. The acquired acoustic characteristics are analyzed to determine if there is any exception of esophagus wall.
Description
Technical field
The present invention relates to esophageal detection instrument and articles for use, be specifically related to acoustics esophageal detection instrument and articles for use thereof.
Background technology
Traditional detecting instrument that is used for the human body esophagus disease, stethoscope is fast, but stethoscope can only provide the information of non-quantitation to the doctor, judges the situation of being examined the people by doctor's experience; To human body esophagus perspective or film making,, only can show interior shape of esophageal lumen and esophagus with X-ray, and be difficult for judging the pathological changes situation of human body esophagus itself in the position in thoracic cavity because esophagus is a kind of tubular tissue; With the esophagoscope method of optical fiber shooting, only observe mucous membrane of esophagus pathological changes situation from esophageal lumen inside, the situation that can't understand esophageal wall flesh layer pathological changes and can't understand the esophagus physiological movement in addition.Per os inserts esophagoscope makes the people very uncomfortable, and this endoscope cost is expensive, often can not be used to be useful for a large amount of crowds' generaI investigation, only is applicable to deep detection.
When human body was swallowed fluid, fluid flowed in esophagus and produces audio signal, and the acoustic features of audio signal is difference with the difference of esophagus internal state, utilized this acoustic features to diagnose being examined people's esophagus health status.But for can quantitative datumization, storable record measurement result, and can make things convenient for noinvasive ground that the people that waits to see the doctor is detected immediately, it be necessary designing the instrument that can be used to measure the acoustic features that is produced when human body is swallowed fluid.
Summary of the invention
The present invention aims to provide a kind of instrument and articles for use that human body is swallowed the audio signal acoustics feature of fluid generation of measuring, and so that necessary measurement data to be provided, auxiliary doctor is diagnosed examining people's esophagus health status.
Thinking of the present invention is: manufacture a kind of instrument that human body is swallowed the audio signal of fluid generation of measuring, send audio signal acoustics feature along esophagus when can the multimetering human body swallowing fluid, change through number again, the signal of telecommunication is become digital signal input computer, have no abnormal according to warp and shape in its frequecy characteristic or transfer characteristic analysis esophageal wall and each section of the esophagus tube chamber.
Technical solution of the present invention is: as shown in Figure 1, acoustics esophageal detection instrument 100 is formed by detecting main frame 110, acoustic transducer group 120, data output interface 130, data output apparatus 140, key groups 150 etc.Detecting main frame 110 is Acoustic detection instrument of multichannel; Acoustic transducer group 120 by several acoustic transducers 121,122 ..., 12X forms, fluid flow through the audio signal acoustics feature that esophagus sends when acoustic transducer collection human body was swallowed fluid, particularly fluid flows through the tone (so-called tone is exactly the frequecy characteristic of sound) of esophagus, and each acoustic transducer measures the time (being exactly that fluid flows through esophagus from certain some transfer characteristic to another required time) of acoustic features.With several acoustic transducers 121,122 of acoustics esophageal detection instrument ..., 12X along human body esophagus fixed order when the chest body surface, acoustic features s1, s2 when each acoustic transducer flows through fluid each acoustic transducer position of esophagus correspondence respectively ..., sX, time t1, t2 when flowing through each acoustic transducer position of esophagus correspondence with fluid ..., tX, be transferred to and detect main frame 110.Detect main frame 110 usefulness special-purpose softwares the detected acoustic features of each acoustic transducer is carried out spectrum analysis, and by data output interface 130 or data output apparatus 140 output measurement results, or export 110 pairs of measurement data of main frame and normal data after testing and compare the data of analyzing etc. after the processing; Time when detecting main frame 110 fluid flow and crossing each acoustic transducer position of esophagus correspondence, be that the acoustics transfer characteristic is analyzed, calculation of fluid flow is crossed the transmission speed of esophagus, and by data output interface 130 or data output apparatus 140 output measurement results, or export 110 pairs of measurement data of main frame and normal data after testing and compare the data of analyzing etc. after the processing; As shown in Figure 2.
But detecting the main frame instrumentation, also can be to add spectrum analysis card or frequency spectrum analyser composition with general purpose computer.With the quality of the analog-digital converter (ADC) of the audio signal that measures preferably reach 16/more than the 64kHz.
Data output apparatus is with to detect main frame conjuncted, also can with detect the main frame split, but dedicated display or printer also can be with universal display device or printer.
Detect the sampling of main frame, can carry out simultaneously, also can carry out with scan mode from each acoustic transducer.
Several acoustic transducers of forming the acoustic transducer group, can as among Fig. 1 for discrete separately; Also can link by the carrying band as shown in Figure 3, to make things convenient for the skin of chest surface of acoustic transducer group along the human body esophagus fixation in human body.
Acoustic transducer can be a mike, and it is good with body surface with taper that mike contacts inner chamber, and outlet diameter Φ should be between 3～25mm, and depth H is 2～20mm, and not open side opening for well, as shown in Figure 4; The sensitivity of mike should be higher than-33.0dB or 25mV/Pa; The ideal Hz-KHz of mike should be between 20Hz～10kHz.
Acoustic transducer also can be other acoustic transducer.
The acoustics esophageal detection instrument has the measured data of memory device record, is used for preserving and the playback measurement data; But the also data of storage standards acoustic features, and the normal space time of each acoustic transducer measurement acoustic features, basis as a comparison or standard.
, acoustic features, particularly fluid that when more accurately experiencing human body swallow fluid fluid flow through esophagus easier for the acoustics esophageal detection instrument flow through the time of the tone and the transfer characteristic of esophagus.Using fluid as swallowing of acoustics esophageal detection instrument articles for use, can be liquid, can be the mixture of liquids and gases, also can be liquid and solid mixture.
Acoustics esophageal detection instrument provided by the present invention does not have intrusion, not damaged, no pain, can repeatedly detect repeatedly, easily accepts human body, when human body is swallowed fluid easily immediately, acoustic features or acoustics transfer characteristic that fluid flows and produced in esophagus, analyze with special-purpose software, for the doctor provides quantitative detection data, help the doctor to be diagnosed the examination esophagel disease to examining people's esophagus health status, it is to the record and the output function of data, make and to transmit data by the Internet, carry out long-range examination, online consultation of doctors.
