Systems and Methods for Enabling and Disabling Insulin Pumps in a Multi-Pump Insulin Pump System

Resumen de: US2025213784A1

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.
