Insulin Pump Meal Bolus Scheduling for Low-Tracking Diabetes Care
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current insulin pumps require precise tracking and matching of carbohydrate intake with insulin delivery, which is not feasible for type II diabetics who lack motivation and willingness to diligently monitor their intake.
Innovation Solution
A simplified insulin pump that delivers insulin based on routine patterns in a diabetic's lifestyle, allowing for programmed meal boluses at predetermined times without requiring precise carbohydrate tracking, with optional user confirmation or modification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If current insulin pumps require precise tracking and matching of carbohydrate intake with insulin delivery, then insulin delivery accuracy is improved, but device complexity and user burden increase
Solution Approach 1:
The pump system automatically monitors glucose levels through integrated sensors and autonomously adjusts insulin delivery based on detected glucose patterns, eliminating the need for manual carbohydrate tracking by the user. The system serves itself by using its own sensor data to make delivery decisions.
Solution Approach 2:
The system continuously monitors glucose levels and uses this feedback to automatically adjust insulin delivery rates. The closed-loop control system processes sensor data in real-time and modifies pump output accordingly, replacing manual carbohydrate counting with automated feedback-based adjustment.
2Measurement precision
If current insulin pumps require diligent monitoring of carbohydrate intake, then insulin delivery precision is improved, but ease of operation deteriorates
Solution Approach 1:
The pump autonomously performs glucose monitoring and insulin dosage calculation without requiring user intervention for carbohydrate tracking. The system independently manages the complex task of matching insulin delivery to metabolic needs using its sensor and processing capabilities.
Solution Approach 2:
The manual mechanical process of counting carbohydrates and calculating insulin doses is replaced with an automated electronic system that uses glucose sensors and microprocessors to determine optimal delivery rates, eliminating the need for user mathematical calculations.
3Ease of operation
If automated meal boluses are delivered at fixed times and amounts, then ease of operation is improved, but adaptability to varying meal patterns deteriorates
Solution Approach 1:
The system transitions from static fixed-time bolus delivery to dynamic adjustment based on real-time glucose monitoring. Insulin delivery rates are continuously modified according to actual glucose level changes and detected patterns, allowing the system to adapt to varying meal times and compositions automatically.
Solution Approach 2:
The system uses periodic glucose monitoring at fixed intervals to detect patterns in the user's routine, then uses these detected patterns to trigger appropriately timed and sized insulin boluses, combining the benefits of automated periodic measurement with adaptive response.

AI summary
A simplified insulin pump allows diabetics to identify routine patterns in their daily lifestyle that provide a generally accurate typical pattern of activity and meals. An infusion regimen can be programmed into the pump that generally correlates with this typical pattern to provide a viable treatment option for a diabetic without the need for specific and precise matching of insulin to carbohydrate consumption or activity level.
