System and method for integration of insulin pumps and continuous glucose monitoring

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.

       a receiver adapted to receive information from a continuous glucose monitor; and
 a processor functionally linked to the receiver to obtain the information from the continuous glucose monitor and to the graphical user interface to control display of information on the graphical user interface, wherein the processor is configured to automatically display a startup screen on the graphical user interface when the graphical user interface is activated from an inactive condition, the startup screen including:
 a current glucose level of a user based off of the information received from the continuous glucose monitor; 
 historical data relating to the glucose level of the user based off of the information received from the continuous glucose monitor; and 
 an estimate of the amount of un-metabolized insulin remaining in the user's body. 
 
 
     
     
         2 . The portable insulin pump of  claim 1 , wherein the historical data is presented in a graphical format illustrating glucose levels of the user over time.

         4 . The portable insulin pump of  claim 1 , further comprising a battery that powers the processor and a reservoir that contains insulin for delivery to the user, and the startup screen further includes at least one of a battery life indicator indicating a remaining life of the battery and a reservoir level indicator indicating a remaining amount of insulin in the reservoir 
     
     
         5 . The portable insulin pump of  claim 1 , wherein the startup screen further includes a bolus object, the bolus object selectable to initiate delivery of an insulin bolus. 
     
     
         6 . The portable insulin pump of  claim 5 , wherein the processor is further configured to, upon selection of the bolus object, display an unlock screen requiring a user to unlock the graphical user interface to initiate delivery of the insulin bolus. 
     
     
         7 . The portable insulin pump of  claim 1 , wherein the graphical user interface includes a touch sensitive screen on which the startup screen is displayed. 
     
     
         8 . The portable insulin pump of  claim 1 , wherein activating the graphical user interface from an inactive condition includes turning the graphical user interface on and activating the graphical user interface from a sleep mode. 
     
     
         9 . The portable insulin pump of  claim 1 , wherein the processor is further configured to display the startup screen when no commands have been entered into the graphical user interface for a predetermined period of time. 
     
     
         10 . A graphical user interface for a portable insulin pump, the graphical user interface adapted to display a startup screen when the graphical user interface is activated from an inactive condition, the startup screen including:
 a current glucose level of a user based off of information received from a continuous glucose monitor;   historical data relating to the glucose level of the user based off of the information received from the continuous glucose monitor; and   an estimate of the amount of un-metabolized insulin remaining in the user's body.   
     
     
         11 . The graphical user interface of  claim 10 , wherein the historical data is presented in a graphical format illustrating glucose levels of the user over time. 
     
     
         12 . The graphical user interface of  claim 10 , wherein the startup screen further includes a timeframe object that is selectable to set the timeframe over which the historical data is displayed. 
     
     
         13 . The graphical user interface of  claim 10 , wherein the startup screen further includes at least one of a battery life indicator indicating a remaining life of a battery and a reservoir level indicator indicating a remaining amount of insulin in a reservoir. 
     
     
         14 . The graphical user interface of  claim 10 , wherein the startup screen further includes a bolus object, the bolus object selectable to initiate delivery of an insulin bolus. 
     
     
         15 . The graphical user interface of  claim 14 , wherein the startup screen is configured to, upon selection of the bolus object, display an unlock screen requiring a user to unlock the graphical user interface to initiate delivery of the insulin bolus. 
     
     
         16 . The graphical user interface of  claim 10 , comprising a touch sensitive screen on which the startup screen is displayed. 
     
     
         17 . The graphical user interface of  claim 10 , wherein activating the graphical user interface from an inactive condition includes turning the graphical user interface on and activating the graphical user interface from a sleep mode. 
     
     
         18 . A portable insulin pump, comprising:
 a user interface;   a receiver adapted to receive information related to a glucose level of a user from a continuous glucose monitor; and   a processor functionally linked to the receiver to obtain the information from the continuous glucose monitor and to the user interface to control display of information on the user interface, wherein the processor is configured to:
 receive a current blood glucose level of the user from the continuous glucose monitor; 
 determine whether the current blood glucose level is above a threshold; and 
 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. 
   
     
     
         19 . The portable insulin pump of  claim 18 , wherein the processor is further configured to:
 receive a confirmation from the user; and   deliver the recommended correction bolus in response to the confirmation.
