A continuous blood glucose monitoring device including a blood glucose classification function fault detection module

Abstract

The invention discloses continuous blood glucose monitoring equipment comprising a blood glucose classification function fault detection module. According to the equipment, a blood glucose PCA monitoring chart is established to perform fault detection on a continuous blood glucose monitoring instrument so that accurate blood glucose signals can be provided. Due to the influences (such as changes of diets and the emotion of a patient) of external source input, the blood glucose fluctuation condition of the patient can change, and correspondingly the SPE value of the blood glucose signals can change obviously; besides, obvious nonlinearity exists between the blood glucose signals, and thus it is impossible to establish a unified and effective control limit for detecting whether a blood glucose meter has a fault or not. In the equipment, the blood glucose signals are divided into multiple classes, and it is ensured that signals in each class are locally linearized and the blood glucose fluctuation conditions in each class are similar, so that it is ensured that fault detection of the blood glucose meter can be better performed in each class, more accurate and credible data are provided for subsequent blood glucose prediction, control and the like, and the equipment has great significance.

Description

technical field [0001] The invention belongs to the research field of blood sugar data processing and analysis, in particular to a continuous blood sugar monitoring device including a blood sugar classification function fault detection module. Background technique [0002] In order to manage and monitor blood glucose levels, it is necessary to measure blood glucose levels, currently using continuous glucose monitoring devices. With the rapid development of continuous blood glucose monitoring (CGM) equipment, higher-precision control becomes possible, and the real-time CGM system plays an important role in the early detection of high / low blood sugar. Alarms can be generated by comparing the relationship between the current measured value and the high / low blood sugar threshold, and timely high and low blood sugar alarms, especially at night, are particularly important for diabetics. But in general, various failures occur in the CGM system, which makes the blood glucose inform...
