1. A medical infusion pump system, comprising:
- a portable pump housing that receives insulin for dispensation to a user, the pump housing at least partially containing a pump drive system to dispense the insulin through a flow path to the user; and
a controller that communicates with the pump drive system to dispense the insulin from the portable pump housing, the controller being configured to calculate an insulin load of the user representing an estimated amount of insulin delivered to the user'"'"'s body which has not yet acted,wherein the controller receives glucose information indicative of a detected blood glucose level of the user, and wherein the controller outputs an alarm when the glucose information indicates that the detected blood glucose level reaches beyond a glucose alarm limit parameter, the glucose alarm limit parameter being adjustable by the controller in response to the insulin load of the user representing the estimated amount of insulin delivered to the user'"'"'s body which has not yet acted.

Abstract
Some embodiments an infusion pump system can be configured to modify alarm limit parameters as the user'"'"'s insulin load increases or decreases. Moreover, in particular embodiments, the infusion pump system can be configured to provide a “missed bolus” or “missed meal” alarm in response to the user'"'"'s blood glucose characteristics, the user'"'"'s insulin load information, or the like.

13. A method of operating an insulin infusion pump system, comprising:
-
receiving glucose information indicative of a detected blood glucose level of a user; determining an insulin load of the user indicative of an estimated amount of insulin delivered to the user'"'"'s body which has not yet acted; in response to the determination of said insulin load of the user indicative of said estimated amount of insulin delivered to the user'"'"'s body which has not yet acted, modifying at least one of an upper alarm limit parameter and a lower alarm limit parameter; and outputting an alarm when the glucose information indicates that the detected blood glucose level is greater than the modified upper alarm limit parameter or is less than the modified lower alarm limit parameter. - View Dependent Claims (14, 15)
