Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
Based on the traditional Chinese medical science auscultation and olfaction device and method of spectral analysis, spectral analysis can be carried out to the gas of characteristics of contaminated respiratory droplets, measure each gas concentration, thus can human body constitution be judged.Device comprises transmitting illuminant 1, input optical fibre 2, air chamber 3, output optical fibre 4, spectrometer 5, computing machine 6.The light beam that transmitting illuminant 1 sends reaches the air chamber 3 being filled with characteristics of contaminated respiratory droplets gas through input optical fibre 2, light beam through air chamber transmission or reflection is incident to output optical fibre 4, reach the entrance slit of spectrometer 5, spectrometer is connected with computing machine 6 through USB, computing machine 6 processes the output data of spectrometer, carry out spectral analysis, thus obtain gas concentration to be measured.Described transmitting illuminant 1 wavelength coverage is 400nm-300um.Described transmitting illuminant 1 wavelength chooses principle is the absorption spectra peak according to gas to be measured, selects the wavelength corresponding with its spectrum peak.Described air chamber 3 is seal chamber, and air chamber is provided with exhaust tube, and wherein gas is filled to the gas that patient breathes out.Described air chamber 3 is transmission-type air chamber or reflective air chamber.Described spectrometer 5 resolution is 4096, and wavelength is 400nm-300um.The wavelength chooses principle of described spectrometer is the wavelength coverage of corresponding transmitting illuminant.The gas concentration to be measured that described computing machine 6 is breathed out for measuring patient according to the spectral information after air chamber absorption, thus judge body.
During specific implementation, with gas NH to be measured
3for example, NH may be comprised first by tested exhalation
3gas be filled in air chamber, connect good whole device according to Fig. 3, set spectrometer and computing machine, open transmitting illuminant, after a period of time, obtain spectrum parameter by operation computing machine, thus measure exhalation NH
3gas concentration, measuring principle is as follows:
When light source sends certain frequency v (cm
-1) single-frequency light penetrate when certain density gas to be measured is housed, the sample in air chamber is at centre frequency v
0have Absorption Line or absorption band, light absorbed with a scattering part after transmissive.If concentration is N, incident intensity is I
0, penetrating light intensity is I
t, can be obtained by Lambert-Beer law:
