Insulin Bolus Adjustment via Touch Screen Slider Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining a bolus amount of insulin for meal events are prone to errors and do not provide accurate and reliable adjustments, especially in complex scenarios, which can lead to suboptimal glycemic control for diabetes management.
Innovation Solution
A method using a control unit with a processor and touch screen display that determines a carbohydrate-based bolus amount of insulin, allowing users to adjust a slider to set both immediate and delayed insulin delivery, with options for a correction bolus, to ensure precise insulin dosing based on meal carbohydrate content and nutrient information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a slider interface is used for adjusting bolus amounts, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent replaces traditional mechanical button presses and manual typing with a graphical slider interface on a touch screen display. Users can adjust bolus amounts by simply dragging a slider with their finger, eliminating the need for complex manual input operations and reducing the risk of typing errors.
Solution Approach 2:
The patent creates a visual copy or representation of the bolus amount adjustment process through the slider interface. The slider position visually corresponds to the selected bolus amount, providing immediate visual feedback and allowing users to verify their selections before confirmation, thereby simplifying the interaction process.
2Adaptability or versatility
If multiple bolus delivery options are provided, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic adjustment capabilities where the bolus delivery scheme can be flexibly modified based on real-time user needs. The system allows users to adjust different portions of the bolus (immediate vs. extended delivery) independently through separate sliders, enabling adaptive response to varying meal compositions and individual patient requirements.
Solution Approach 2:
The patent divides the total bolus amount into separate adjustable components (immediate bolus portion and extended bolus portion), each with its own slider control. This segmentation allows users to independently optimize each portion based on their specific needs, providing versatility without overwhelming the user with a single complex adjustment mechanism.
3Reliability
If real-time adjustment capabilities are implemented, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent incorporates real-time visual feedback through the touch screen display, showing users the current slider position and corresponding bolus amount as they adjust. The system provides immediate confirmation of selected values and allows users to review their selections before final confirmation, reducing errors and improving reliability through transparent, real-time feedback loops.
Data Source
AI summary
A method for adjusting a bolus amount of insulin for a meal event using a control unit having a processing unit and a touch screen display as well as a medical control device and a medical system configured to perform the method. Additionally, the present disclosure relates to a computer program or computer program product that, when executed, performs the method. A carbohydrate-based bolus amount of insulin can be delivered in a first bolus and a second bolus. A movable slider displayed on the touch screen display can be used to adjust the relative amounts of the first and second boli.
