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.

1. An infusion pump system to deliver an infusion formulation to a user, comprising: a sensing device to monitor glucose levels in the user;a computing element to receive sensing device input and to adjust delivery of the infusion formulation as a function of the rate of change of the glucose levels
1. An infusion pump system to deliver an infusion formulation to a user, comprising: a sensing device to monitor glucose levels in the user;a computing element to receive sensing device input and to adjust delivery of the infusion formulation as a function of the rate of change of the glucose levels in the user over time, wherein the infusion formulation delivered to the user is limited to maximum and minimum values; anda pump in communication with the computing element to deliver the infusion formulation to the user;wherein if the adjusted delivery of the infusion formulation is not within the maximum and minimum values, the computing element determines whether a user-initiated signal is present in order to proceed. 2. The infusion pump system of claim 1, wherein delivery of the infusion formulation is limited to a maximum of a percentage higher than a pre-programmed nominal basal rate of delivery. 3. The infusion pump system of claim 1, wherein delivery of the infusion formulation is limited to a maximum of a percentage lower than a pre-programmed nominal basal rate of delivery. 4. The infusion pump system of claim 1, wherein a delivery rate of the infusion formulation is limited from dropping below a minimum allowable rate. 5. The infusion pump system of claim 1, wherein a delivery rate of the infusion formulation is limited from rising above a maximum allowable rate. 6. The infusion pump system of claim 1, wherein the pump is an implanted pump. 7. The infusion pump system of claim 1, wherein the pump is an external pump. 8. The infusion pump system of claim 1, wherein the infusion formulation is insulin. 9. The infusion pump system of claim 1, wherein if the adjusted delivery of the infusion formulation is not within the maximum and minimum values and there is no user-initiated signal present, the computing element queries the user. 10. A method of delivering an infusion formulation to a user, comprising: monitoring glucose levels in the user;receiving input of the glucose levels monitored and adjusting delivery of the infusion formulation as a function of the rate of change of the glucose levels in the user over time, wherein the infusion formulation delivered to the user is limited to maximum and minimum values;delivering the infusion formulation to the user; anddetermining whether a user-initiated signal is present in order to proceed, if the adjusted delivery of the infusion formulation is not within the maximum and minimum values. 11. The method of claim 10, wherein delivery of the infusion formulation is limited to a maximum of a percentage higher than a pre-programmed nominal basal rate of delivery. 12. The method of claim 10, wherein delivery of the infusion formulation is limited to a maximum of a percentage lower than a pre-programmed nominal basal rate of delivery. 13.

The method of claim 10, wherein a delivery rate of the infusion formulation is limited from rising above a maximum allowable rate. 15. The method of claim 10, wherein delivering the infusion formulation is by an implanted pump. 16. The method of claim 10, wherein delivering the infusion formulation is by an external pump. 17. The method of claim 10, wherein the infusion formulation is insulin. 18. The method of claim 10, further including: querying the user if the adjusted delivery of the infusion formulation is not within the maximum and minimum values and there is no user-initiated signal present. 19. An infusion pump system to deliver an infusion formulation to a user, comprising: a sensing device to monitor glucose levels in the user;a computing element to receive sensing device input and to adjust delivery of the infusion formulation as a function of the rate of change of the glucose levels in the user over time, wherein the infusion formulation delivered to the user is limited to maximum and minimum values; anda pump in communication with the computing element to deliver the infusion formulation to the user;wherein if the adjusted delivery of the infusion formulation is not within the maximum and minimum values and there is no user-initiated signal present, the computing element queries the user. 20. The infusion pump system of claim 19, wherein delivery of the infusion formulation is limited to a maximum of a percentage higher than a pre-programmed nominal basal rate of delivery. 21. The infusion pump system of claim 19, wherein delivery of the infusion formulation is limited to a maximum of a percentage lower than a pre-programmed nominal basal rate of delivery. 22. The infusion pump system of claim 19, wherein a delivery rate of the infusion formulation is limited from dropping below a minimum allowable rate. 23. The infusion pump system of claim 19, wherein a delivery rate of the infusion formulation is limited from rising above a maximum allowable rate. 24. The infusion pump system of claim 19, wherein the pump is an implanted pump. 25. The infusion pump system of claim 19, wherein the pump is an external pump. 26. The infusion pump system of claim 19, wherein the infusion formulation is insulin. 27. A method of delivering an infusion formulation to a user, comprising: monitoring glucose levels in the user;receiving input of the glucose levels monitored and adjusting delivery of the infusion formulation as a function of the rate of change of the glucose levels in the user over time, wherein the infusion formulation delivered to the user is limited to maximum and minimum values;delivering the infusion formulation to the user; andquerying the user if the adjusted delivery of the infusion formulation is not within the maximum and minimum values and there is no user-initiated signal present. 28. The method of claim 27, wherein delivery of the infusion formulation is limited to a maximum of a percentage higher than a pre-programmed nominal basal rate of delivery. 29. The method of claim 27, wherein delivery of the infusion formulation is limited to a maximum of a percentage lower than a pre-programmed nominal basal rate of delivery. 30.
