Safety limits for closed-loop infusion pump control
First Claim
1. A process for providing safety limits on the delivery of infusion formulation by an infusion pump system in response to a sensed biological state, comprising:
- monitoring a biological state;
providing information about the biological state to a computing element, the computing element being programmed to regulate the delivery of the infusion formulation in accordance with the information;
communicating a user-initiated event signal to the computing element, the user-initiated event signal being representative of an event affecting the biological state; and
providing a plurality of user-selectable operators corresponding to respective ones of a plurality of event rankings for ranking respective events;
wherein the computing element is further programmed to receive the user-initiated event signal and initiate a variation in the delivery of the infusion formulation in accordance with the received user-initiated signal.

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.
