Patent ID: 7704226

Claim:
An external infusion device for delivering insulin from a reservoir into a body of a user, the external infusion device comprising: at least one drive mechanism operatively couplable to the reservoir to deliver insulin into the body of the user; at least one processor to control the external infusion device; at least one power supply; at least one display device operatively coupled to the at least one processor to provide visual information to the user; at least one input device operatively coupled to the at least one processor to allow the user to command the at least one processor; and a housing; wherein the external infusion device is programmed to deliver three different types of basal insulin, the three types of basal insulin including current basal insulin, future basal insulin and time-shifted basal insulin, time-shifted basal insulin being a portion of the future basal insulin that is added to the current basal insulin, the portion of future basal insulin being insulin that is to be delivered during a future time period, the delivery of the time-shifted basal insulin automatically eliminates delivery of the future basal insulin during the future time period.
