Evaluation method and evaluation device for blood glucose fluctuation

Abstract

The invention provides an evaluation method and evaluation device blood for glucose fluctuation. The method comprises the steps that continuous blood glucose monitoring data, collected at a preset frequency, of multiple monitoring periods are characterized in the form of a matrix, the number of rows of the matrix corresponds to the number of the monitoring periods, the number of columns of the matrix corresponds to the number of the continuous blood glucose monitoring data collected in one monitoring period, and all elements in the matrix are the values of the collected continuous blood glucose monitoring data; gradient calculation is conducted on the matrix so as to obtain a transverse gradient and a longitudinal gradient, wherein the transverse gradient represents the fluctuation situation of the continuous blood glucose monitoring data in all the monitoring periods, and the longitudinal gradient represents the fluctuation situation of the continuous blood glucose monitoring data among all the monitoring periods; a gradient variation value is calculated based on the transverse gradient and the longitudinal gradient, and then the fluctuation amplitude and the fluctuation frequencyof blood glucose are evaluated through the gradient variation value. With the method and the device, the fluctuation amplitude and the fluctuation frequency of blood glucose can be evaluated at the same time through the gradient variation value, and hypoglycemia can be effectively predicted.

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...

[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 cu
