Blood glucose concentration detection method and device based on polarized light magneto-optical effect

Abstract

The invention discloses a blood sugar concentration detection method and device based on a polarized light magneto-optic effect. The method comprises the following steps: on the basis of the magneto-optic deflection effect, a sample test tube filled with a blood sugar solution is placed into a magnetic cavity formed by a magnetic confinement body, the rotary light deflection angle is increased under the action of a magnetic confinement body, and light intensity of light passing through a polarization analyzer is detected by a light intensity meter; the light intensity in case of the existence of the sample test tube in the magnetic cavity is enabled to be consistent with the light intensity in case of the absence of the sample test tube in the magnetic cavity through a rotary polarization analyzer, and a deflection angle of the polarization analyzer is measured, thus realizing detection of the blood sugar concentration in the sample test tube. The polarized light magneto-optic effect-based blood sugar concentration detection method is high in detection speed, high in detection precision, stable and reliable, provides a technical basis for bio-medical and clinically medical fields of China and brings great economical and social benefits.

Description

technical field [0001] The invention relates to the technical field of solution concentration detection, in particular to a method and device for detecting blood sugar concentration based on the magneto-optic effect of polarized light. Background technique [0002] With the invention of lasers, light plays an important role on the stage of the human world, especially in the field of combining light with life science and medicine. There are many optical technologies serving human health, such as optical medical diagnosis, optical imaging, human body composition Spectral detection technology, etc. At present, the routine detection of blood glucose concentration is through finger pricking and venous blood collection. This method brings certain psychological and economic burdens to patients, and even leads to secondary infection. Therefore, non-destructive detection technology of blood glucose has attracted much attention. At present, the most representative optical non-destruc...
