Automated Insulin Dosing With Suppressed Glucose Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
People with diabetes face significant cognitive and emotional burdens in managing their insulin therapy, requiring frequent dosing determinations and recalibration of therapeutic parameters, which can lead to errors and complications due to the need for user-specific data input and ongoing monitoring.
Innovation Solution
A burden-free glucose management system that determines insulin delivery amounts based on previous data without requiring user-specific physiological or behavioral data input, using continuous glucose monitoring and insulin pump data to automatically adjust insulin delivery and hide alerts unless critical, thereby reducing user interaction and error risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If user-specific physiological or behavioral data input is required for insulin dosing determinations, then dosing accuracy can be improved, but user cognitive burden and complexity of operation increase
Solution Approach 1:
The system automatically collects and processes physiological data (glucose levels, insulin delivery) and behavioral data (meal times, exercise) without requiring manual user input. The glucose management system self-adjusts insulin delivery based on algorithmic analysis of sensor data, eliminating the need for users to manually enter data or make dosing calculations.
Solution Approach 2:
The patent replaces the manual mechanical process of data entry and dosing calculation with an automated electronic system. Sensors continuously monitor glucose levels and the controller automatically processes this data to determine insulin delivery amounts, substituting human cognitive processing with computational algorithms.
2Reliability
If frequent monitoring and recalibration of therapeutic parameters is performed, then glycemic control effectiveness is improved, but user time commitment and operational complexity increase
Solution Approach 1:
The system implements continuous glucose monitoring rather than intermittent manual checks. The glucose sensor continuously measures interstitial fluid glucose levels, and the controller continuously adjusts insulin delivery based on real-time data, maintaining constant therapeutic action without requiring periodic user intervention for recalibration.
Solution Approach 2:
The system automatically performs recalibration of therapeutic parameters based on continuous sensor data analysis. The algorithm self-adjusts insulin sensitivity factors and dosing parameters without requiring user recalculation or reconfiguration, maintaining effective glycemic control while eliminating time-consuming manual recalibration tasks.
3Ease of operation
If automated insulin delivery system is implemented, then user burden is reduced, but system complexity and potential for technical failure increase
Solution Approach 1:
The patent combines multiple functions into an integrated system: the glucose sensor, controller, and insulin pump are merged into a coordinated system where the controller receives glucose data from the sensor and automatically commands insulin delivery to the pump. This integration reduces user burden by consolidating multiple separate tasks into a single automated system.

AI summary
Some embodiments include burden-free insulin delivery systems and methods. Some embodiments include a method comprising: receiving previous insulin delivery data at a user device from an insulin pump; receiving estimated glucose data at the user device from a continuous glucose monitor; determining that the estimated glucose value is approaching or has passed a threshold; and in response to determining that the estimated glucose value is approaching or has surpassed the threshold, not providing an indication to the user through a user interface that the estimated glucose value is approaching or surpassed the threshold.
