Safety limits for closed-loop infusion pump control
First Claim
1. An infusion pump system for delivering an infusion media to a user, the infusion pump system comprising:
- a sensing device to monitor glucose levels in the user;
a user interface for receiving user input relating to a food ingestation event;
a pump for delivering an infusion media to a user;
a computing element operatively connected to the pump and configured to adjust delivery of the infusion media dependent at least in part on glucose levels monitored by the sensing device and at least in part on user input received through the user interface;
the computing element configured to adjust delivery of the infusion media by the pump, based at least in part on an initial user input received by the user interface, relating to the food ingestation event,the computing element configured to further adjust delivery of the infusion media by the pump, based at least in part on an updated user input received by the user interface, relating to the food ingestation event.

Abstract
A system and process for providing safety limits on the delivery of an infusion formulation by an infusion pump system in response to a sensed biological state. The safety limits may comprise user-initiated event signals corresponding to events that may significantly affect the biological state. The safety limits may further comprise user-initiated event ranking signals for respective events which specify a degree, quantity, or measure for the respective event. The user-initiated event and event ranking signals may be communicated to a computing element associated with the infusion pump by an associated communication device having a user interface which comprises a plurality of user-selectable operators for entering information about the events and event rankings.

13. A method of making an infusion pump system for delivering an infusion media to a user, the method comprising:
-
providing a sensing device to monitor glucose levels in the user; providing a user interface for receiving user input relating a food ingestation event; providing a pump for delivering an infusion media to a user; coupling a computing element to the pump; and configuring the computing element to adjust delivery of the infusion media dependent at least in part on glucose levels monitored by the sensing device and at least in part on user input received through the user interface; further configuring the computing element to adjust delivery of the infusion media by the pump, based at least in part on an initial user input received by the user interface, relating to the food ingestation event; and further configuring the computing element to further adjust delivery of the infusion media by the pump, based at least in part on an updated user input received by the user interface, relating to the food ingestation event. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)
