Insulin Pump Interface for Temporary Glucose Target Override
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current closed-loop insulin infusion systems for diabetic patients are complex and require extensive patient parameterization, leading to potential errors and stress, especially when temporarily overriding predefined glucose targets to avoid hyperglycemia.
Innovation Solution
A computerized device with a processor that determines a control parameter for a fluid infusion pump based on patient data and a standard scheme, featuring a user interface with a button to temporarily amend the scheme, reducing the risk of hypoglycemia and simplifying target overrides without complex parametrization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex parametrization scheme is used to allow temporary target overrule, then the system can provide flexible control options, but the device complexity increases and causes errors for patients not familiar with computers
Solution Approach 1:
The patent extracts the temporary target overrule function from the complex parametrization scheme by providing a dedicated button on the welcome screen that directly activates the override mode without requiring patients to navigate through complex parameter settings. This separates the essential function from the complexity, allowing patients to easily access temporary target overrule while keeping the interface simple.
Solution Approach 2:
The system provides self-service by automatically managing the temporary scheme activation and deactivation through a simple button press. When the patient presses the button on the welcome screen, the system automatically switches from the standard scheme to the temporary scheme, eliminating the need for manual parametrization and complex user configuration.
2Adaptability or versatility
If extensive patient parameterization is required, then the system can be customized for individual patients, but the ease of operation decreases and causes stress for patients
Solution Approach 1:
The patent extracts the essential temporary target overrule function from the complex parameterization process by placing a dedicated button on the welcome screen. This allows patients to access the override function immediately without needing to understand or configure complex parameters, maintaining patient-specific customization while dramatically improving ease of operation.
Solution Approach 2:
The system prepares the temporary scheme in advance as a pre-configured option that can be activated with a single button press. The temporary scheme is already set up with appropriate parameters, so patients don't need to perform any preliminary configuration actions - they simply press the button to activate the pre-prepared override mode.
3Extent of automation
If a standard scheme with predefined targets is used, then the system provides automated control, but the adaptability to temporary patient needs is reduced
Solution Approach 1:
The patent implements dynamics by allowing the system to switch between two operational modes: the standard scheme for automated control and the temporary scheme for adapted control. The welcome screen button enables dynamic transition between these modes, allowing the system to adapt to temporary patient needs while maintaining automated control capabilities when the temporary mode is not active.
Solution Approach 2:
The system applies local quality by providing different control characteristics in different operational contexts. The standard scheme provides aggressive automated control for typical situations, while the temporary scheme provides more conservative control for specific temporary needs. The button on the welcome screen allows patients to select which local quality (control characteristic) is appropriate for their current situation.

AI summary
The computerized device repeatedly determines a command to control the infusion of fluid in a diabetic patient. It comprises a processor (6) which repeatedly determines a value for a control parameter of a fluid infusion pump based on patient data stored in a database (27) and on a standard scheme, a user interface (7) which comprises a welcome screen (9) and at least a further screen displayable following an interaction of the patient with the welcome screen. The welcome screen (9) comprises an actuable button (24) which enables to amend the standard scheme for a predefined temporary lapse of time into a temporary scheme.
