Abstract

The invention relates to a non-invasive blood glucose detection method and device based on differential temperature state monitoring. The method performs cooling treatment on the skin of a part of the area to be measured, and collects a low temperature data matrix of the skin in the cooling area and a normal temperature data matrix of the skin in a non-cooling area, Obtain the low temperature data curve and the normal temperature data curve, perform curve fitting on the two column matrices respectively, perform inversion temperature detection on the fitted low temperature data curve and the fitted normal temperature data curve, and check the low temperature data after the inversion temperature detection meets the requirements. The column matrix and the normal temperature data column matrix are fitted to obtain a second-order curve reflecting the physical state, calculate the first-order differential equation of the second-order curve, calculate the sampling integral of the first-order differential equation, and combine the differential equation integral and the blood sugar calculation formula to obtain the current blood sugar status. The invention truly realizes the non-invasive detection of blood sugar, the accuracy of blood sugar detection, and has wider applicability.

Description

technical field [0001] The invention belongs to the technical field of blood sugar detection, and in particular relates to a method and a device for non-invasively acquiring blood sugar values ​​by using a temperature sensor. Background technique [0002] Blood sugar testing is a preventive measure that must be carried out in the daily life of diabetics. Blood samples are collected to detect blood sugar levels to monitor changes in physical status. The blood sample collection process requires users to prick their fingers, and this process will cause greater psychological pressure and unavoidable pain to the user. If an accurate user's blood glucose value can be obtained in a non-invasive way, it will play a very important role in the control and monitoring of diabetes. [0003] Chinese patent CN108652640B discloses a non-invasive blood glucose detection method and system based on ECG signals. By acquiring the pRRx sequence of the ECG signal and performing linear and nonline...
