Airspace light-diving differential wavelength spectro meter for detecting artery blood content and detection method thereof

Abstract

The invention discloses an airspace prismatic difference spectrum apparatus for artery blood ingredients detection, it is accurate, convenient, and it can measure ingredients of several organizations, it includes wideband lamp source with bandwidth of 600-1300nm, prismatic device and light path, light sensitive sensor, analog detecting channel, A / D converting model, CPU and its peripheral circuits; the prismatic device and the light path include prismatic device and light path devices matching to the prismatic device; the prismatic device uses gratings; the light path include wideband lamp source, the first condenser, measured human organization, the second condenser, grating and light sensitive element array; the light path output is photoelectric pulse wave signal; if arranges with light regulating baffle, thus the output of the light path is high frequency signal; the signal is converted into digital signal through A / D converting model and then processed with CPU, thus it can acquire the content of the primary ingredients in the artery blood. The invention also discloses the detection method of above mentioned spectrum apparatus.

Description

technical field [0001] The invention relates to a clinical medical testing instrument and method, in particular to an arterial blood component measuring instrument and method. Background technique [0002] There is no doubt about the importance and great value of non-invasive detection of tissue components for the diagnosis and treatment of diseases. Not only that, the realization of non-invasive detection of tissue components also has great academic significance and value in signal sensing, detection and processing. [0003] In 1977, American scientist Jobsis first reported the experimental results of using near-infrared light to observe the changes in the content of oxyhemoglobin, reduced hemoglobin and cytochrome c in the brain of adult cats, revealing that near-infrared light (700-1300nm) is lower in biological tissues. The decay rate and feasibility of non-invasive monitoring of tissue oxygen concentration with near-infrared spectroscopy. In view of the extremely attr...
