Abstract

A non-disease diagnosis and therapeutic blood glucose detection method based on a slit waveguide. The annular slit area between the straight waveguide and the micro-ring waveguide is a detection channel for the blood sample to be detected to flow through. The refractive index of the straight waveguide material is higher than that of blood. The sample has a high refractive index, and the method includes the following steps: 1) performing a calibration test using a blood sample with normal blood sugar, passing the blood sample with normal blood sugar in the annular slit area, and passing light through a straight waveguide with a high refractive index, and then testing micro The resonant wavelength of the ring waveguide is the calibration wavelength; 2) Pass the blood sample to be detected in the annular slit area, and detect the current resonant wavelength of the micro-ring waveguide after passing the light in the high refractive index straight waveguide, if the current resonant wavelength is equal to the calibration wavelength , it is determined that the blood glucose concentration of the blood sample to be detected is normal; if the resonance wavelength is not equal to the calibration wavelength, it is determined that the blood glucose concentration of the blood sample to be detected is abnormal. The invention simplifies the structure, reduces the size and reduces the cost while satisfying high detection efficiency and fast response.

Description

technical field [0001] The invention relates to the field of blood sugar detection, in particular to a blood sugar detection method. Background technique [0002] In the existing blood sugar detection technology, conventional blood sugar detection is an invasive detection, and medical treatment is slow, low in efficiency, and not high in intelligence. [0003] Someone proposes to use microwave technology to realize blood glucose detection, for example, the patent number is 200710200028.X, and the title of the invention is: a Chinese invention patent application for a non-invasive rapid blood glucose detector. Utilizing microwave technology to realize blood glucose detection has good rapidity of detection, but there are technical defects: the entire detection equipment has complex structure, large size, slow response, and high cost. [0004] In 2004, the research group of Professor Michal Lipson of Cornell University in the United States first proposed the concept of slot wa...
