1. A portable insulin pump, comprising:
- a reservoir configured to contain insulin;
a pumping mechanism configured to deliver insulin in the reservoir to a user;
a user interface;
a receiver adapted to receive information from a continuous glucose monitor system; and
a processor functionally linked to the receiver to obtain the information from the continuous glucose monitor system and to the user interface to control display of information on the user interface, wherein the processor is configured to;
receive a substantially continuous data stream from the continuous glucose monitor system;
process the substantially continuous data stream to obtain estimated glucose levels for the user;
receive, separately from the substantially continuous data stream, a numeric value of a current blood glucose level of the user from the continuous glucose monitor system when the user enters the numeric value obtained from a blood sample into the continuous glucose monitor system for calibration of the continuous glucose monitor system;
determine from the numeric value whether the current blood glucose level is above a threshold;
if the current blood glucose level is above the threshold, automatically calculate a bolus of insulin to bring the user'"'"'s blood glucose level below the threshold and present the bolus to the user on the user interface as a recommended correction bolus; and
deliver the recommended correction bolus to the user.

Abstract
A portable insulin pump can integrate and display data from a continuous glucose monitor (CGM) to allow a user to more readily determine whether any interaction with the pump is necessary. Data from the CGM can automatically be transmitted to the pump and can be displayed for user analysis or automatically analyzed to present recommendations to the user based on combined data from the CGM and the pump.
