Blood optical-detection method and device

Abstract

The invention discloses a blood optical-detection device and method. The blood optical-detection device comprises a light source, a miniature array optical-fiber column, a spectrometer, optical fibers, a data line and a data processing end, wherein the miniature array optical-fiber column consists of paired miniature optical-fiber needle columns; each miniature optical-fiber needle column is provided with a reflecting film and a light-transmitting film; the optical fibers are respectively adopted for connection between the miniature array optical-fiber column and the light source and between the miniature array optical-fiber column and the spectrometer, and the spectrometer is connected with the data processing end by the data line. The method using the device to detect blood comprises thefollowing steps that the light source emits light, the light enters the blood by one miniature optical-fiber needle column to generate a spectral Raman effect with components of the blood, and then outgoes by another miniature optical-fiber needle column, the spectrometer splits the outgoing light, and then converts light signals after light splitting into electric signals, and the data processing end carries out analysis and calculation on the electric signals by a mathematical model and obtains a detection result.

Description

technical field [0001] The invention relates to a blood optical detection method and device. Background technique [0002] The content of blood components can reflect certain physical conditions of the human body. Conventional blood component detection and analysis mostly requires the collection of blood samples by pricking the skin of the finger tip or drawing a large amount of blood from a vein, and then obtaining the values ​​of biochemical indicators in the blood through spectroscopic or chemical analysis. Blood component detection and analysis methods mainly use microscopes to check the types and sizes of cells in blood, gas chromatography liquid chromatography and mass spectrometry and other spectroscopic optical techniques, and enzyme-linked immunosorbent assays. Existing testing methods for blood components are painful, there is a risk of infection, and the waiting time for test results is long. Moreover, the existing detection methods have various problems and bot...
