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;
a controller that communicates with the pump drive system to dispense the insulin from the portable pump housing, wherein the controller comprises a controller housing that removably attaches to the pump housing, the controller being electrically connected to the pump drive system when the controller housing is removably attached to the pump housing; and
a monitoring device that communicates glucose information to the controller, the glucose information being indicative of a blood glucose level of the user,wherein the controller outputs an alarm when the glucose information indicates that the blood glucose level reaches beyond a glucose alarm limit parameter, the glucose alarm limit parameter being adjustable by the controller in response to an insulin load of the user.

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.

3. 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, wherein the portable pump housing receives a prefilled cartridge of the insulin; a controller that communicates with the pump drive system to dispense the insulin from the portable pump housing; and a monitoring device that communicates glucose information to the controller, the glucose information being indicative of a blood glucose level of the user, wherein the controller outputs an alarm when the glucose information indicates that the blood glucose level reaches beyond a glucose alarm limit parameter, the glucose alarm limit parameter being adjustable by the controller in response to an insulin load of the user. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11)

12. 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; a controller that communicates with the pump drive system to dispense the insulin from the portable pump housing; and a monitoring device that communicates glucose information to the controller, the glucose information being indicative of a blood glucose level of the user, the glucose information being stored in a computer-readable memory device over a period of time, wherein the controller accesses the glucose information stored in the memory device to detect a glucose information pattern indicative of a missed insulin bolus, wherein the computer-readable memory device stores the glucose information received from the monitoring device and time values associated with the glucose information, and wherein the glucose information pattern indicative of the missed insulin bolus comprises a local minimum within a blood glucose curve based upon the glucose information stored in the memory device over the period of time. - View Dependent Claims (13, 14)
