CGM Backfill Display for Distinguishing Lost-Link Glucose Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for continuous glucose monitoring fail to provide timely and reliable presentation of analyte data, such as in a certain technical area, where non-invasive, transdermal and/or implantable electrochemical sensors face challenges in presenting glucose data discreetly and reliably, particularly when communication links are interrupted.
Innovation Solution
A method and apparatus for handling backfill data by graphically distinguishing it from non-backfill data using distinct indicators and notifications, enabling users to distinguish between current and past glucose data trends.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If backfill data is presented without distinction from non-backfill data, then the display is simpler, but the reliability of glucose monitoring is reduced due to potential misinterpretation of data timing
Solution Approach 1:
The patent applies color changes by displaying backfill data in a distinct color different from non-backfill data. This visual differentiation allows users to immediately distinguish between historical and current glucose measurements, maintaining display simplicity while ensuring reliable interpretation of data timing and status.
2Loss of information
If backfill data is stored during wireless link loss, then data completeness is improved, but the loss of time for real-time monitoring increases
Solution Approach 1:
The patent implements preliminary action by storing backfill data locally in the sensor device during wireless link interruptions. This ensures data completeness is maintained by capturing glucose measurements in advance, while the distinct visual presentation immediately indicates when the data was collected, managing user expectations about real-time status.
Solution Approach 2:
The patent uses an intermediary approach by introducing a visual indicator (distinct color or icon) that mediates between the stored backfill data and the user. This indicator communicates the data's historical nature without requiring complex additional displays or notifications, thus preserving data completeness while minimizing perceived time loss.
3Reliability
If graphically distinct indicators are added to distinguish backfill data, then the reliability of data interpretation is improved, but the device complexity increases
Solution Approach 1:
The patent employs color changes as a simple yet effective graphical indicator to distinguish backfill data. By changing the display color of backfill data points, the system reliably communicates data timing status without adding complex interface elements, maintaining low device complexity while improving interpretation reliability.
Solution Approach 2:
The patent applies discarding and recovering by using simple, discarded visual conventions (like color coding) that are easily recovered and understood by users. This approach maintains reliability through familiar visual cues while avoiding the complexity of elaborate indicator systems.

AI summary
Methods and apparatus, including computer program products, are provided for backfilling. In some example embodiments, there is provided a method that includes receiving, at a receiver, backfill data representative of sensor data stored, at a continuous blood glucose sensor and transmitter assembly, due to a loss of a wireless link between the receiver and the continuous blood glucose sensor and transmitter assembly; generating, at the receiver, at least one of a notification or a graphically distinct indicator for presentation at a display of the receiver, the at least one of the notification or the graphically distinct indicator enabling the backfill data to be graphically distinguished, when presented at the display, from non-backfill data; and generating, at the receiver, a view including the backfill data, the non-backfill data, and the generated at least one of the notification or the graphically distinct indicator.
