Time-domain light-deivisding 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, the technology project is: it includes wideband lamp source with bandwidth of 600-1300nm, prismatic apparatus and its light path, light sensitive sensor, analog detecting channels, A / D converting model, CPU and its peripheral circuits; the mentioned prismatic device and its light path include prismatic device and light path device matching with the prismatic device. The prismatic device uses AOTF, filter piece or Fourier prismatic apparatus; the light emitted by the wideband lamp source is converted into digital signal through light path and the circuit conversion, the digital signal is post processed by the data processing system with CPU as centre, thus calculates the content of the primary ingredients in the artery blood. The invention also discloses the detection method with 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 the 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, the 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) has a lower concentration in biological tissues. decay rate and the feasibility of noninvasive monitoring of tissue blood oxygen concentration by near-infrared spectroscopy.
