Abstract

The invention discloses a method for improving near-infrared noninvasive blood glucose detection precision. The method comprises the following steps: firstly, establishing a universal mathematical model among near-infrared reflection intensity and temperature of a detection part, pressure on a probe, individual difference and a user activity state relative to a real blood glucose value; secondly,establishing a special data sample set for the user by acquiring activity information closely related to blood glucose change of the user in different states for a long time, temperature of the detection part, pressure information of the detection part to the probe and real blood glucose information of the user at the moment; and by combining the sample set, obtaining a change rule of noninvasivedetection values of the user in different states by training through a machine learning algorithm, and establishing a blood glucose prediction model. Thus, the precision of near-infrared blood glucosedetection is improved.

Description

technical field [0001] The invention is suitable for a near-infrared non-invasive blood sugar detection device with temperature and pressure detection functions, belongs to the field of human body non-invasive blood sugar detection, and specifically relates to a method for improving the accuracy of near-infrared non-invasive blood sugar detection. Background technique [0002] Among the current non-invasive blood sugar detection technologies, near-infrared photoelectric detection technology is considered to be one of the most promising technologies. Near-infrared photoelectric detection technology determines the concentration of glucose by detecting the absorption intensity of near-infrared light. Generally, optical probes are used. Contact the detection part to collect the diffuse reflection or transmission signal of near-infrared light. However, due to differences in detection conditions, when near-infrared human blood glucose detection, the temperature of the detection si...
