Solution Overview
Problem
Existing infusion pump systems face challenges with unreliable and inconsistent wireless communication between components like continuous glucose monitoring devices and infusion pumps, leading to potential loss of critical medical data due to interference, especially when devices are positioned relative to the human body.
Innovation Solution
A method and system for coordinating wireless communications in infusion pump systems by initiating a communication session, determining signal quality metrics, and providing user guidance for optimal device placement based on signal strength, using a remote device to relay data and adjust positions if necessary, and employing technologies like Bluetooth Direction Finding to enhance connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communication is used between infusion pump and CGM device, then remote monitoring and data transmission capability is improved, but communication reliability deteriorates due to signal interference and location-dependent connectivity issues
Solution Approach 1:
The system performs preliminary location tracking and communication quality assessment before critical data transmission is needed. By continuously monitoring the relative positions of the infusion pump and CGM device, the system can proactively identify potential communication issues and alert users to reposition devices before data loss occurs.
Solution Approach 2:
The system implements continuous feedback loops that monitor communication signal quality and device locations. This feedback is used to dynamically adjust alerts and notifications to users, providing real-time information about communication status and guiding users to optimize device placement for reliable connectivity.
2Reliability
If device placement is optimized for communication signal quality, then communication reliability is improved, but user convenience and flexibility deteriorate due to restricted positioning options
Solution Approach 1:
The system applies communication optimization selectively rather than requiring perfect signal quality at all times. By implementing thresholds for when alerts should be triggered, the system allows for acceptable ranges of device placement that maintain sufficient communication reliability without imposing overly restrictive positioning requirements on users.
3Reliability
If continuous communication monitoring is implemented, then communication issues are detected earlier improving data transmission reliability, but energy consumption increases
Solution Approach 1:
The system performs communication quality assessments and location tracking at periodic intervals rather than continuously. This periodic monitoring approach maintains adequate detection capability for communication issues while significantly reducing the energy consumption associated with constant monitoring activities.
