Abstract

The invention discloses a blood sugar measuring device and a blood sugar measuring method, aiming to solve the technical problems in the prior art that the Raman spectrum signal is weak, easily affected by fluorescence and stray light, and the measurement sensitivity and accuracy are not high. The blood sugar measuring device of the present invention includes a light source unit and a detection unit; the light source unit includes a laser light source, a mounting cylinder and a plurality of light source fibers; the detection unit includes a mounting column, a detection fiber, a spectral imaging component and a computer. The blood glucose measuring device of the present invention can realize both non-invasive measurement of the tissue to be measured and minimally invasive measurement of the internal components of the tissue to be measured. Mode measurement and transmission mode measurement, by selecting measurement methods suitable for different tissue parts, make the measurement more accurate and reliable.

Description

technical field [0001] The invention relates to a blood sugar measuring device, in particular to a blood sugar measuring device and a blood sugar measuring method. Background technique [0002] In recent years, diabetes, as a high-incidence disease, has seriously affected the health and happiness of human beings, and the detection of blood sugar has become a key link in the prevention and treatment of diabetes. Existing measurement methods by collecting blood mainly focus on non-invasive blood glucose measurement by means of optical means such as near-infrared spectroscopy, photoacoustic spectroscopy, and Raman spectroscopy. Raman spectroscopy has become one of the most potential technologies for blood glucose detection because it can realize non-invasive and accurate identification and detection of substances through the rich vibrational spectral information of molecules. However, there are still some technical difficulties in Raman spectroscopy, such as the signal acquisi...
