Infusion pump systems and methods

摘要

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.

主权项

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.
