A blood sugar fluctuation evaluation method and evaluation device

Abstract

The invention provides a blood sugar fluctuation evaluation method and evaluation device. The method includes: representing the continuous blood glucose monitoring data of multiple monitoring periods collected at a preset frequency into a matrix form, the number of rows of the matrix corresponds to the number of monitoring periods, and the number of columns of the matrix corresponds to the number of continuous blood glucose monitoring data collected within one monitoring period. Each element in the matrix is ​​the collected continuous blood glucose monitoring data value; the gradient calculation is performed on the matrix to obtain the horizontal gradient and the longitudinal gradient, where the horizontal gradient represents the fluctuation of the continuous blood glucose monitoring data in each monitoring period, and the vertical gradient represents the fluctuation of the continuous blood glucose monitoring data in each monitoring cycle. The fluctuation of continuous blood glucose monitoring data between monitoring cycles; the gradient variation value is calculated based on the horizontal gradient and the longitudinal gradient, and then the gradient variation value is used to evaluate the blood glucose fluctuation range and fluctuation frequency. The method and device of the invention can simultaneously evaluate the fluctuation range and frequency of blood sugar by using the gradient variation value, and effectively predict hypoglycemia.

Description

technical field [0001] The invention relates to the technical field of blood sugar evaluation, in particular to a blood sugar fluctuation evaluation method and evaluation device. Background technique [0002] Diabetes mellitus is a metabolic disorder caused by defective insulin secretion or impaired biological action. With the aging of the population and changes in eating habits, the incidence of diabetes is on the rise. So far, there is no feasible cure for diabetes. Diabetic patients are advised to adjust the dosage of oral hypoglycemic drugs and insulin or adjust diet and exercise in time by continuously monitoring changes in blood sugar concentration, so as to control blood sugar fluctuations and prevent or reduce complications. disease. Continuous glucose monitoring (CGM) is a technology that continuously monitors the concentration of glucose in the subcutaneous interstitial fluid through a glucose sensor. Generally speaking, CGM can continuously obtain blood glucose...

AI Technical Summary

Problems solved by technology

[0016] However, the above calculation of blood glucose standard deviation and blood glucose variation coefficient of CGM data can only calculate the magnitude of blood glucose fluctuations, while ignoring the frequency of blood glucose fluctuations

Therefore, the current blood sugar fluctuation parameters are difficult to simultaneously characterize the blood sugar fluctuation amplitude and blood sugar fluctuation frequency, which may lead to the loss of some information, and cannot describe the real fluctuation of blood sugar
