Abstract

The invention relates to a noninvasive blood glucose detection method and device based on differential temperature state monitoring. The method comprises the following steps: cooling the skin of a part region of a to-be-detected part, collecting a low-temperature data matrix of the skin in a cooling region and a normal-temperature data matrix of the skin in a non-cooling region, obtaining a low-temperature data curve and a normal-temperature data curve, performing curve fitting on the two column matrixes respectively, performing temperature inversion detection on the fitted low-temperature data curve and the fitted normal-temperature data curve, fitting the low-temperature data column matrix and the normal-temperature data column matrix after the temperature inversion detection meets the requirement to obtain a second-order curve reflecting the physical state, calculating a first-order differential equation of the second-order curve, calculating the sampling integral of the first-order differential equation, and combining the integral of the differential equation with the blood glucose calculation formula to obtain the current blood glucose state. According to the invention, noninvasive detection of blood glucose and accuracy of blood glucose detection are truly realized, and the method 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 people with diabetes must carry out in their daily life. By collecting blood samples to detect blood sugar levels, they can monitor changes in their 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 users. If accurate user blood glucose values ​​can be obtained in a non-invasive manner, 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 electrocardiographic signals. By obtaining the pRRx sequence of electrocardiogr...
