Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional insulin therapy methods, including insulin pumps, often require multiple daily injections and complex user interaction, leading to inconvenience and difficulty in maintaining optimal blood glucose levels, with risks of high or low blood sugar levels.
Innovation Solution
An insulin pump system with a controller that receives blood glucose data, presents questions via a user interface when levels deviate from targets, and provides recommended actions based on user responses, utilizing decision trees and rule modules to guide users in managing their diabetes effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional insulin therapy with multiple daily injections is used, then blood glucose control improves, but user convenience and ease of operation deteriorates
Solution Approach 1:
The insulin pump system performs self-monitoring of blood glucose levels and automatically calculates recommended insulin doses based on pre-programmed algorithms. The system serves itself by continuously monitoring its own operational status and making autonomous decisions about insulin delivery timing and dosage, reducing the burden on users while maintaining reliable blood glucose control
Solution Approach 2:
The system implements continuous feedback loops where blood glucose measurements are fed back into the control algorithm, which then adjusts future insulin delivery recommendations. This closed-loop feedback mechanism ensures reliable blood glucose management while automating the complex calculations and decision-making process, improving ease of operation
2Adaptability or versatility
If insulin pump with sophisticated features is used, then insulin delivery flexibility improves, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary processing layer between the user and the complex pump functions. This intermediary system translates simple user inputs into complex insulin delivery decisions using pre-programmed algorithms and decision trees, thereby providing insulin delivery flexibility without exposing the user to the underlying complexity
Solution Approach 2:
The control system is segmented into modular functional blocks, each handling specific aspects of insulin delivery (basal rate control, bolus calculation, blood glucose monitoring). This segmentation allows the system to provide sophisticated flexible insulin delivery while keeping each individual module simple and easy to understand, reducing overall perceived complexity
3Reliability
If real-time blood glucose monitoring and guidance is implemented, then blood glucose control improves, but device complexity and information processing requirements increase
Solution Approach 1:
The system pre-calculates insulin delivery recommendations and presents them to users before actual insulin delivery is needed. By performing preliminary calculations based on current blood glucose levels and predicted future trends, the system improves blood glucose control while keeping the real-time processing requirements manageable
Data Source
AI summary
An apparatus comprising a pump configured to deliver insulin, an input configured to receive blood glucose data, a user interface, and a controller communicatively coupled to the pump, the input, and the user interface. The controller includes a blood glucose data module to compare the blood glucose data to a target blood glucose level for an insulin pump user. The controller is configured to present a question related to the blood glucose level via the user interface when the blood glucose level is different than the target blood glucose level, receive a response to the question via the user interface, and present a recommended user action based at least in part on the response. Other devices, systems, and methods are disclosed.
