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 activates the pump drive system to dispense the insulin from the portable pump housing, wherein the controller is configured to receive glucose information being indicative of a blood glucose level of the user; and
a user interface coupled to the controller including a display device that contemporaneously displays a glucose value indicative of the blood glucose level of the user and a total insulin load indicative of bolus and basal insulin dosages that have dispensed but not yet acted in the user.

Abstract
Some embodiments an infusion pump system can be used to determine a user'"'"'s total insulin load (TIL) that provides an accurate indication of the insulin previously delivered to the user'"'"'s body which has not yet acted. In particular embodiments, the TIL can account for both the bolus deliveries and the basal deliveries that have occurred over a period of time. Such information may be useful, for example, when the infusion pump is operated in conjunction with a continuous glucose monitoring device.

14. The system of claim 14, wherein the monitoring device comprises a portable housing wearable on the user'"'"'s skin, a sensor shaft that penetrates into the user'"'"'s skin, and a wireless communication device to transmit the glucose information to a wireless communication device of the controller.

15. 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 activates the pump drive system to dispense the insulin from the portable pump housing, wherein the controller is configured to receive glucose information being indicative of a blood glucose level of the user, and wherein controller is configured to determine a total insulin load indicative of bolus and basal insulin dosages that have dispensed but not yet acted in the user, the total insulin load being determined by the controller according to a function that accounts for at least (i) a bolus insulin load indicative of one or more bolus insulin dosages that have been dispensed into the user but not yet acted in the user, and (ii) a basal insulin load indicative of one or more basal insulin dosages that have been dispensed into the user from the portable infusion pump system but not yet acted in the user; and a user interface coupled to the controller including a display device that displays the total insulin load indicative of bolus and basal insulin dosages that have dispensed but not yet acted in the user. - View Dependent Claims (16, 17, 18, 19, 20)
