Multi-Pump Insulin Delivery Switching With Automatic Settings Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Switching patch insulin pumps results in inconsistency in insulin delivery due to locally saved settings, disrupting the continuity of insulin delivery when one pump is replaced by another.
Innovation Solution
A mobile device facilitates the transfer of pump configuration data and enables/disables insulin pumps in a multi-pump system, ensuring seamless insulin delivery by adjusting settings on the new pump based on data from the old pump.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple patch pumps are used to maintain continuous insulin delivery, then the reliability of insulin delivery is improved, but the complexity of managing and switching between pumps increases
Solution Approach 1:
The mobile device serves as an intermediary between the user and the pump system, automatically handling configuration data transfer and pump switching operations. The mobile device receives settings from the disabled pump, processes them, and applies them to the enabled pump, eliminating the need for manual configuration replication and simplifying the switching process.
Solution Approach 2:
The system performs self-service by automatically transferring configuration data between pumps without requiring user intervention for settings replication. The disabled pump automatically shares its configuration with the mobile device, which then automatically configures the enabled pump, making the switching process autonomous and reducing management complexity.
2Ease of operation
If pump settings are saved locally on each pump, then the ease of operation is improved, but the consistency of insulin delivery during pump switching deteriorates
Solution Approach 1:
The system implements feedback by having the mobile device continuously monitor pump status and automatically trigger configuration data transfer when switching occurs. The disabled pump's settings are automatically retrieved and applied to the enabled pump, ensuring consistency is maintained through automated feedback loops rather than manual user actions.
Solution Approach 2:
Instead of relying on manual copying of settings, the system uses automated digital copying of configuration data from the disabled pump to the enabled pump through the mobile device. This ensures accurate and complete replication of all settings, including insulin delivery parameters, without human error.
3Use of energy by moving object
If the pump is disabled for battery recharging, then the battery can be recharged, but the continuity of insulin delivery is disrupted
Solution Approach 1:
The system performs preliminary actions by having the user switch to a second pump before the first pump needs to be recharged. The configuration data transfer is initiated and completed in advance, so when the first pump is disabled for charging, the second pump is already configured and ready to maintain insulin delivery without interruption.
Solution Approach 2:
The system maintains continuity of useful action by ensuring that insulin delivery never stops during the recharge process. The mobile device coordinates the switching process to ensure that one pump is always operational and delivering insulin, while the other pump is being recharged, thus maintaining continuous insulin delivery throughout the recharge cycle.

AI summary
Systems and methods are provided for enabling and disabling insulin pumps in a multi-pump insulin pump system. For example, multiple pumps (e.g., patch pumps) may be rotated to deliver insulin to a user. In one example, one patch pump may be worn while another patch pump is charging. Once the battery of the patch pump worn by the user is depleted, a mobile device may cause the enabled pump in operation and worn by the user to send the latest pump settings and configuration data to the mobile device which will share the information with the disabled pump. The disabled pump will then update the pump settings based on this information and the mobile device may active the pump such that is now enabled for insulin delivery. The mobile device may also facilitate pairing between the patch pumps and a CGM device as they enabled for use and disabled.
