Abstract

Disclosed is a non-invasive diabetes prediction system based on photo plethysmo graphy. The non-invasive diabetes prediction system comprises an optical signal emitter, a driving circuit, a receivingcircuit and a processor module, wherein the optical signal emitter is driven by the driving circuit to obtain an optical signal with fixed wavelength and intensity and emit the optical signal; the receiving circuit is used for converting the received optical signal of the photo plethysmo graphy into an electric signal of the photo plethysmo graphy, carrying out amplification filtering and digital-to-analog conversion, and sending a digital signal of the photo plethysmo graphy to the processor module; and the processor module is used for carrying out signal processing, feature extraction and modeling prediction on the digital signal of the photo plethysmo graphy, and visually displaying the digital signal of the photo plethysmo graphy. According to the noninvasive diabetes prediction systemand method based on the photo plethysmo graphy, noninvasive, real-time and convenient diabetes screening and illness risk prediction can be achieved.

Description

technical field [0001] The invention relates to the field of medical and health technologies, in particular to a system and method for realizing non-invasive diabetes screening and disease risk prediction by an optical sensor. Background technique [0002] Diabetes is one of the most serious chronic metabolic diseases in the world. As of 2019, there are already 460 million diabetic patients worldwide, and this number is expected to increase to 700 million by 2045. Diabetes and its complications have a great impact on individuals. and a burden on society. According to statistics, currently about 50% of diabetic patients (mostly type 2 diabetes) are undiagnosed. Therefore, it is urgent to diagnose this undiagnosed population in order to provide appropriate care and prevent the disease from aggravating. [0003] At present, the glucose tolerance test is the "gold standard" for diabetes diagnosis, but this method requires subjects to go to the hospital for invasive blood glucos...
