Detection method for optical noninvasive measurement of blood glucose concentrations based on lips

Abstract

The invention discloses a detection method for optical noninvasive measurement of blood glucose concentrations based on lips. The detection method comprises the following steps that a human body lip model is manufactured; testing blood with different blood glucose concentrations is prepared; the blood glucose concentrations of the blood in the lip model are changed, the blood with the different blood glucose concentrations is used for testing, and thus spectrums of the blood with the different blood glucose concentrations are obtained; the obtained spectrums are subjected to spectral normalization processing, a calibrated spectrum matrix is spliced according to preset data, various spectral data are associated through a data fusion technology, a preset mathematic model is trained accordingto the spectral data, corresponding blood glucose values serving as input vectors and corresponding temperature values serving as input vectors, and thus a blood glucose measuring model is obtained;and then the blood with the different blood glucose concentrations is used for testing, thus Raman spectrums and infrared absorption spectrums of a set of to-be-tested blood glucose are obtained, a measuring matrix is constituted according to a preset method, and a prediction model is used for predicting the blood glucose values. The precision and reliability of measurement are improved; and the blood glucose of a human body can be noninvasively measured and can also be used for measuring other parameters.

Description

technical field [0001] The invention belongs to the technical field of optical detection, and in particular relates to a detection method for noninvasively measuring blood sugar concentration based on lip optics. Background technique [0002] Hundreds of millions of people around the world suffer from diabetes, which is a disease caused by endocrine and metabolic regulation disorders. Diabetes has become the second leading cause of death in the United States. The chronic complications of diabetes are not fully understood, and its effects on the circulatory system and blood vessels can damage tissues and organs of the body. To avoid hyperglycemia or hypoglycemia, adhere to a diet that includes carbohydrates and monosaturated fats with limited amounts of sucrose, combined with insulin medication. In order to accurately know the dosage of the drug, it is necessary to continuously detect the blood sugar level. The current method used is to frequently take a small amount of blo...
