Abstract

The invention discloses a noninvasive blood glucose detecting system and a noninvasive blood glucose detecting method. The noninvasive blood glucose detecting system comprises an optical sensing module and a calculating-analyzing module, wherein the optical sensing module comprises a light source, a light-splitting device, a slit assembly, a detection region and a photosensitive sensor; the slit assembly comprises a slit plate and a moving device, a group of crevices for light to pass through are formed in the slit plate, and the moving device moves to enable light to pass through different crevices; the detection region is used for reflecting light to the photosensitive sensor; the optical sensing module is used for acquiring comparison light information and detection light information; the photosensitive sensor is used for converting a light signal into an electric signal and sending the electric signal to the calculating-analyzing module; the calculating-analyzing module comprises adata processing module and a data comparison module; the data processing module is used for processing the comparison light information, establishing a spectrum information base and processing the detection light information into the independent spectrum information; and the data comparison module is used for carrying out integrating degree comparison on the independent spectrum information and the spectrum information base, so as to acquire an estimated blood glucose value of the detection light information.

Description

technical field [0001] The invention relates to the technical field of medical electronics, and more particularly to a non-invasive blood sugar detection system and a blood sugar estimation method. Background technique [0002] Diabetes mellitus is a metabolic endocrine disease characterized by hyperglycemia, which can cause various complications and even lead to death. Regular detection of blood glucose concentration is currently an effective method recommended by medicine to control diabetes. The emergence of non-invasive blood glucose detection methods can reduce the pain of patients in the process of blood glucose concentration detection and reduce the risk of infection. [0003] In non-invasive blood glucose measurement based on optical methods, infrared spectroscopy has excellent characteristics and has been adopted by more and more researchers in recent years, which is one of the important development directions of non-invasive blood glucose detection research.

Problems solved by technology

[0004] But on the other hand, because the measured object is a living body, the signal is very weak, and the relevant problems involve many and complicated disciplines. As far as the current research status is concerned, due to individual differences, there are spectral overlaps, low signal-to-noise ratio, background noise interference, and accurate Non-invasive blood glucose detection is still in the laboratory stage and has not been widely used clinically
