Insulin Pump Basal Rate Testing and Correction Bolus Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current insulin pumps are cumbersome to program and have practical limits, making it difficult to maintain consistent blood glucose levels in diabetic patients, limiting their control over glucose regulation.
Innovation Solution
An insulin pump with a programmable circuit that receives current blood glucose levels, determines if they are above a threshold, and calculates a correction bolus value, allowing users to input threshold values and percentages to adjust insulin delivery accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual injection with syringe is used, then insulin delivery is simple, but it is cumbersome and limits patient activities
Solution Approach 1:
The pump system automatically monitors blood glucose levels and calculates correction bolus values without requiring manual programming by the patient. The programmable circuit autonomously determines when correction boluses are needed based on glucose threshold comparisons, eliminating the need for patients to manually program injection schedules and doses.
Solution Approach 2:
The system dynamically adjusts insulin delivery parameters by comparing current blood glucose levels against threshold values and automatically calculating correction bolus amounts. This parameter-based automated control replaces static manual programming with adaptive real-time adjustments.
2Adaptability or versatility
If current pumps are programmed with fixed limits, then programming is simplified, but control over blood glucose levels is reduced
Solution Approach 1:
The pump system transitions from fixed programming to dynamic adaptive control. The programmable circuit continuously compares blood glucose levels against thresholds and automatically adjusts correction bolus calculations in real-time, enabling flexible response to varying glucose conditions without requiring complex manual reprogramming.
Solution Approach 2:
The system implements closed-loop feedback by monitoring blood glucose levels and using this information to automatically calculate and deliver correction boluses. The programmable circuit receives glucose data, determines if thresholds are exceeded, and adjusts insulin delivery accordingly, creating an adaptive control system that responds to actual physiological conditions.
3Measurement precision
If automated correction bolus calculation is implemented, then blood glucose control is improved, but programming complexity increases
Solution Approach 1:
The system performs preliminary setup by establishing glucose threshold values and correction factors during initial programming. Once configured, the programmable circuit automatically executes the correction bolus calculation algorithm without requiring further user intervention, performing the complex calculations in advance and in real-time based on pre-established parameters.
