In vitro performance evaluating system of continuous blood sugar monitoring sensor

Abstract

The invention discloses an in vitro performance evaluating system of a continuous blood sugar monitoring sensor. The in vitro performance evaluating system comprises a reagent storage unit (1), a sampling unit (2), a sample mixing unit (3), a sample distributing unit (4), a detecting unit (5), a control unit (6), and a CGM sensor evaluating instrument (7). The in vitro performance evaluating system is capable of analyzing and evaluating the in vitro performance including sensitivity, response speed, detection range, accuracy, continuous working service life, interference resistance, temperature association coefficient, oxygen dependence degree and other parameters of the continuous blood sugar monitoring sensor as well as the performance change of the to-be-monitored sensor in a continuous working state, and is capable of effectively detecting and evaluating the in vitro detection performance of the to-be-monitored sensor.

Description

technical field [0001] The invention relates to the field of continuous blood sugar monitoring, in particular to an in vitro performance evaluation system of a continuous blood sugar monitoring sensor. Background technique [0002] In the past ten years, the continuous blood glucose monitoring system (CGMS, Glucose Continuous Monitor System) has developed rapidly, mainly including blood glucose sensors implanted under the skin and matching instruments in vitro. There are many imperfections in the existing system: (1) The detection time is long, and the blood glucose level of the subcutaneous tissue fluid (ISF) needs to be monitored continuously for more than 72 hours; (2) The operation is relatively complicated, and finger blood is generally required every day In vitro detection for comparison and correction; (3) Since the blood glucose sensor is implanted subcutaneously and works continuously, its performance will continue to decline, mainly such as sensitivity, accuracy, r...
