Solution Overview
Problem
Existing continuous glucose monitoring systems face challenges in accurately generating initial calibration information due to the potential for wrong initial calibration values, which can lead to inaccurate blood glucose measurements.
Innovation Solution
A method for initial calibration of a continuous biological sensor that determines whether the initial calibration value obtained from an additional blood gathering-type sensor is abnormal, and if so, obtains an additional initial calibration value to accurately generate initial calibration information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If initial calibration is performed using a blood gathering-type sensor, then calibration information can be obtained, but wrong initial calibration values may be generated leading to measurement errors
Solution Approach 1:
The system performs preliminary validation of the initial calibration value by comparing it with a reference value obtained from a blood glucose meter before using it for calibration. This preliminary check prevents wrong calibration values from being applied, thereby resolving the contradiction between obtaining calibration information and ensuring its reliability.
Solution Approach 2:
The system implements a feedback mechanism where the initial calibration value is validated against a reference value, and only after successful validation is the calibration information generated. This feedback loop ensures that unreliable calibration values are rejected, improving both measurement precision and calibration reliability.
2Reliability
If multiple initial calibration values are obtained to ensure accuracy, then calibration reliability improves, but the burden of blood gathering increases
Solution Approach 1:
The system obtains at least two initial calibration values through blood gathering, which is more than the single value traditionally used. This partial excessive action ensures calibration reliability by providing multiple data points for validation, while the validation process ensures that the additional blood gathering is only performed when necessary for accurate calibration.

AI summary
The present disclosure relates to a method for initial calibration of a continuous biological sensor. More specifically, the present disclosure relates a method for initial calibration of a continuous biological sensor, in which generation of initial calibration information based on a wrong initial calibration value may be prevented by determining whether an initial calibration value obtained by using an additional blood gathering-type sensor for the initial calibration is abnormal and generating initial calibration information and in which when the initial calibration value obtained for the initial calibration is abnormal, the initial calibration information may be accurately generated by obtaining an additional initial calibration value to generate the initial calibration information.
