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.

18. An infusion pump system for use in delivery of an infusion formulation, the system comprising:
-
a pump for delivering measured doses of an infusion formulation;
a sensing device for sensing a biological state;
a computing element communicating with the sensing device, the computing element being programmed to receive information about the sensed biological state from the sensing device and to regulate the delivery of the infusion formulation in accordance with the received information; and
a communication device communicating with the computing element, the communication device for communicating a user-initiated event signal to the computing element, the user-initiated event signal being representative of an event affecting the sensed biological state;
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. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
