Continuous high-precision detecting instrument for blood glucose concentration of human body based on trace blood sampling

Abstract

The invention discloses a continuous high-precision detecting instrument for blood glucose concentration of a human body based on trace blood sampling. The detecting instrument comprises a continuous blood sampling pipeline, a sample inlet pipeline, a detecting pipeline, a first cleaning pipeline and a second cleaning pipeline, wherein the continuous blood sampling pipeline is used for implementing trace blood sampling; the sample inlet pipeline is connected with the output end of the continuous blood sampling pipeline and used for mixing blood and anticoagulant and delivering the mixed liquid to the detecting pipeline to realize continuous measurement of the blood glucose concentration; the detecting pipeline is connected with the output end of the sample inlet pipeline and used for detecting the blood; the first cleaning pipeline is respectively connected with the sample inlet pipeline and the detecting pipeline and used for cleaning the sample inlet pipeline and the detecting pipeline; and the second cleaning pipeline is connected with the continuous blood sampling pipeline and used for cleaning the continuous blood sampling pipeline. The detecting instrument does not cause fluctuation of the blood glucose concentration due to trace continuous blood sampling. The detecting instrument realizes integrated operation of uninterrupted and non-interference blood sampling in the glucose detecting process, uninterrupted and non-interference blood sampling in the cleaning process of the sample inlet and detecting pipelines, buffer solution reference measurement, blood glucose concentration measurement, cleaning of the sample inlet and detecting pipelines and the like.

Description

technical field [0001] The invention relates to a device for continuously monitoring glucose concentration in human blood. In particular, it relates to a continuous high-precision detection instrument for human blood glucose concentration based on micro blood sampling, which includes a continuous blood drawing line with a small amount of blood, a sampling line, a detection line and a cleaning line. Background technique [0002] With the improvement of people's living standards, changes in diet structure and lifestyle, population aging and the increase in the incidence of obesity, the incidence of diabetes is increasing year by year. The importance of continuous blood glucose monitoring in the diagnosis and treatment of diabetes has been increasingly recognized by people. If painless and uninterrupted continuous blood sugar monitoring can be performed on patients and more closely data on blood sugar drift changes can be provided, it will be able to reflect the "full picture"...

AI Technical Summary

Problems solved by technology

Due to the limitations of detection methods, blood glucose monitoring can only be done at isolated time points, and the results reflect the instantaneous blood glucose at certain times of the day. Instantaneous blood glucose values ​​are affected by many factors such as exercise, diet, drugs, and mood swings. There are certain one-sidedness and inaccuracies
