Glucose Data Gap Recovery in Continuous Monitoring Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Continuous glucose monitoring systems (CGMS) face challenges in accurately detecting hypoglycemic conditions due to communication failures between the sensor transmitter and the terminal, leading to unreceived glucose information, which can result in delayed detection and potential health risks for diabetic patients.
Innovation Solution
A method is implemented to indicate a data gap during communication failures and, upon resolution, fill this gap by outputting biometric information stored in the sensor transmitter, including generating and outputting biometric information during the failure period, and sequentially outputting stored information after the failure is resolved.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the terminal continuously receives glucose information from the sensor transmitter, then the glucose monitoring is accurate and timely, but communication failures cause data loss and detection delays
Solution Approach 1:
The sensor transmitter stores glucose information locally in its memory before communication occurs. This preliminary storage ensures that data is preserved even when communication fails, allowing the terminal to retrieve stored information later and prevent data loss during communication interruptions.
Solution Approach 2:
The system implements a feedback mechanism where the terminal detects communication failures, notifies the sensor transmitter, and triggers a retransmission of stored glucose information. This closed-loop feedback ensures data completeness by automatically recovering from communication interruptions.
2Loss of information
If the terminal notifies the user of unreceived glucose information, then data completeness is maintained, but the user experience becomes more complex with additional notifications and actions required
Solution Approach 1:
The sensor transmitter autonomously stores glucose information in its memory without requiring user intervention. When communication fails, the system automatically manages data retention and retransmission, eliminating the need for users to manually handle data gaps or complex notification procedures.
Solution Approach 2:
The system pre-stores glucose information in the sensor transmitter's memory before any communication issues arise. This preliminary data preservation allows the system to automatically recover lost information without requiring user awareness or action, simplifying the user experience while maintaining data completeness.

AI summary
One embodiment may provide a method of outputting blood glucose data including obtaining biometric information in response to an advertisement transmitted by a sensor transmitter, generating the biometric information as output, in the case that a communication failure occurs, indicating a data gap during a period of the communication failure, and if the communication failure is resolved, filling the data gap during a period from a time point when the communication failure is resolved to one advertisement which arrives after the communication failure is resolved.
