Infusion Pump System and Methods
First Claim
Patent Images
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; 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.

17. A method of operating an insulin infusion pump system, comprising:
-
receiving glucose information indicative of a glucose level of a user; determining an insulin load of the user indicative of estimated amount of insulin delivered to the user'"'"'s body; in response to determining the insulin load of the user, 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 glucose level is greater than the modified upper alarm limit parameter or is less than the modified lower alarm limit parameter. - View Dependent Claims (18, 19)

20. 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. - View Dependent Claims (21, 22, 23, 24)
