Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Infusion pump systems face challenges in managing transitions between operating modes, leading to potential disruptions and inefficiencies in user experience due to unsatisfied preconditions and alerts, which can compromise user safety and compliance with regulatory requirements.
Innovation Solution
A system that uses processors to obtain status information, exit closed-loop operating modes, and generate user notifications for remedial actions to improve the viability of subsequent mode transitions, while supervising transitions to maintain control over physiological conditions and ensure compliance with delivery rules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system supports multiple operating modes with preconditions, then the adaptability and control over physiological conditions are improved, but the device complexity and difficulty of detecting preconditions increase
Solution Approach 1:
The system performs preliminary detection of preconditions before allowing mode transitions. The processor checks whether required preconditions are satisfied prior to exiting the current operating mode, preventing transitions until conditions are appropriate. This advance checking resolves the contradiction by automating the complexity of precondition management while enabling versatile mode transitions.
Solution Approach 2:
The system provides feedback to users when preconditions are not satisfied for mode transitions. By notifying users of unmet preconditions and the specific requirements, the system reduces the perceived complexity while maintaining adaptability across multiple operating modes.
2Reliability
If the system enforces preconditions for mode entry, then the reliability and user safety are improved, but the ease of operation decreases due to denied mode entry
Solution Approach 1:
The system checks preconditions in advance before denying mode entry. By evaluating whether required conditions are met prior to allowing transition, the system maintains reliability while providing users with clear information about what conditions prevent mode entry, reducing frustration and improving ease of operation.
Solution Approach 2:
The system provides informative feedback to users when mode entry is denied, explaining which preconditions are not satisfied. This transparency transforms a potentially frustrating experience into an educational opportunity, maintaining reliability while improving ease of operation by helping users understand and address the blocking conditions.
3Reliability
If the system monitors conditions during operation, then the reliability and detection of issues are improved, but the quantity of alerts and user disruptions increase
Solution Approach 1:
The system takes preliminary anti-action by preventing mode transitions when preconditions are not satisfied, thereby avoiding the generation of alerts that would occur if transitions were attempted under inappropriate conditions. This proactive prevention reduces the quantity of disruptive alerts while maintaining reliable monitoring of operating conditions.

AI summary
Techniques disclosed herein relate to managing transitions into fluid delivery device operating modes. In some embodiments, the techniques involve obtaining status information pertaining to operation of a fluid delivery device, the status information including fluid delivery data, exiting a closed-loop operating mode of the fluid delivery device based on the status information, and, after exiting the closed-loop operating mode, causing generation of a user notification recommending a remedial action to improve viability of a subsequent instance of the closed-loop operating mode. The closed-loop operating mode is an operating mode in which dosage commands are automatically generated based on sensor measurement data.
