Abstract

Embodiments are directed to portable infusion devices, systems, and methods of using the same for dispensing materials. In some cases, the devices, systems and methods may be used for infusing a material such as medicament, e.g., insulin, into a body in need thereof.

Claims

1. A method of delivering medicament to a patient with a portable infusion pump system, comprising:

presenting a home screen on a touch-screen display of a portable infusion pump, the home screen including a plurality of touch selectable objects including a bolus delivery object;

receiving user input touch selecting the bolus delivery object;

presenting a bolus setup page on the touch-screen display in response to touch selection of the bolus delivery object, the bolus setup page simultaneously presenting a plurality of touch selectable objects, each of which enables entry of user input for a bolus calculation upon being touch selected;

receiving a numerical user input value via a touch selection of one of the plurality of touch selectable objects on the bolus setup page;

calculating a bolus based on the numerical user input value;

displaying the calculated bolus on the bolus setup page adjacent the plurality of touch selectable objects; and

delivering the calculated bolus to the user with the portable infusion pump.

2. The method of claim 1, further comprising:

returning the touch-screen display to the home screen while the calculated bolus is being delivered;

presenting a plurality of discrete dynamic bolus status indicator objects on the home screen after or simultaneously with returning to the home screen;

changing appearance of the plurality of discrete dynamic bolus status indicator objects while the calculated bolus is being delivered; and

stop changing appearance of the plurality of discrete dynamic bolus status indicator objects when the calculated bolus delivery is completed.

3. The method of claim 2, wherein changing appearance of the plurality of discrete dynamic bolus status indicator objects includes changing a color of the dynamic bolus status indicator objects to indicate that the calculated bolus delivery is ongoing.

4. The method of claim 1, wherein presenting a home screen on a touch-screen display of the portable infusion pump includes presenting the home screen on the touchscreen display upon activation of the portable infusion pump.

5. The method of claim 1, wherein the plurality of touch selectable objects presented on the bolus setup page includes a food object and further comprising interpreting the numerical user input value to be an amount of carbohydrates.

6. The method of claim 1, wherein the plurality of touch selectable objects presented on the bolus setup page includes a blood glucose object, and further comprising interpreting the numerical user input value to be a blood glucose level.

7. The method of claim 1, further comprising:

presenting a virtual numeric keypad on the touch-screen display in response to selection of the one of the plurality of touch selectable objects, and

receiving the numerical user input value via the virtual numeric keypad.

8. The method of claim 1, further comprising presenting a view calculation object on the bolus setup page, the view calculation object being touch selectable to display on the touch-screen how the calculated bolus was calculated based on the numerical user input value.

9. The method of claim 1, further comprising:

returning the touch-screen display to the home screen while the calculated bolus is being delivered;

presenting a touch selectable stop insulin object on the home screen while the calculated bolus is being delivered;

receiving user input touch selecting the stop insulin object while the calculated bolus delivery is being delivered; and

stopping delivery of the calculated bolus in response to the touch selection of the stop insulin object.

10. A method of programming a portable infusion pump system to deliver medicament, comprising:

selecting a touch selectable bolus delivery object on a home screen of a touch-screen display of a portable infusion pump, the home screen including a plurality of touch selectable objects including the bolus delivery object;

selecting one of a plurality of touch selectable objects simultaneously presented on a bolus setup page displayed on the touch-screen display in response to touch selection of the bolus delivery object;

entering a numerical user input value following touch selection of the one of the plurality of touch selectable objects on the bolus setup page;

viewing a calculated bolus oh the bolus setup page displayed adjacent the plurality of touch selectable objects, the calculated bolus having been calculated based on the numerical user input value; and

causing the portable infusion pump to initiate delivery of the calculated bolus.

11. The method of claim 10, further comprising activating the portable infusion pump and selecting the touch selectable bolus delivery object occurs immediately as the first touch input following activation.

12. The method of claim 10, wherein selecting one of the plurality of touch selectable objects presented on the bolus setup page comprises selecting a food object and wherein the numerical user input value represents an amount of carbohydrates.

13. The method of claim 10, wherein selecting one of the plurality of touch selectable objects presented on the bolus setup page comprises selecting a blood glucose object, and wherein the numerical user input value represents a blood glucose level.

14. The method of claim 10, wherein entering a numerical user input value includes entering the numerical user input value into a virtual keypad displayed on the touch-screen in response to selecting one of the plurality of touch selectable objects on the bolus setup page.

15. The method of claim 10, further comprising selecting a view calculation object presented on the bolus setup page, the view calculation object being touch selectable to display on the touch-screen how the calculated bolus was calculated based on the numerical user input value.

16. The method of claim 10, further comprising selecting a stop insulin object presented on the home screen while the calculated bolus delivery is ongoing, the selection of the stop insulin object causing delivery of the calculated bolus to be stopped.

17. The method of claim 10, further comprising:

receiving an indication that the calculated bolus delivery is ongoing via a plurality of discrete dynamic bolus status indicator objects displayed on the home screen, the appearance of the plurality of discrete dynamic bolus status indicator objects changing while the calculated bolus delivery is ongoing; and

receiving an indication that the calculated bolus delivery is completed when the appearance of the plurality of discrete dynamic bolus status indicator objects stop changing.

18. The method of claim 17, wherein the changing the appearance of the plurality of discrete dynamic bolus status indicator objects includes changing a color of the dynamic bolus status indicator objects while the calculated bolus delivery is ongoing.

19. A method of delivering medicament to a patient with a portable infusion pump system, comprising:

presenting a home screen on a touch-screen display of a portable infusion pump, the home screen including a plurality of touch selectable objects including a bolus delivery object;

receiving user input touch selecting the bolus delivery object;

presenting a bolus setup page on the touch-screen display of the portable infusion pump, the bolus set up page simultaneously presenting a plurality of touch selectable objects each of which enables entry of user input for a bolus calculation upon being touch selected;

presenting a virtual numeric keypad on the touch-screen display in response to touch selection of one of the plurality of touch selectable objects on the bolus set up page;

receiving a numerical user input value via the virtual numeric keypad;

calculating a bolus delivery based on the numerical user input value;

returning to the bolus setup page following calculation of the calculated bolus;

displaying the calculated bolus on the bolus setup page adjacent the plurality of touch selectable objects; and

delivering the calculated bolus to the user with the portable infusion pump.

20. The method of claim 19, wherein the plurality of touch selectable objects presented on the bolus setup page includes both a food object and a blood glucose object, and wherein the step of calculating a bolus utilizes (a) the numerical user input value as an amount of carbohydrates when the one of the plurality of touch selectable objects that was touch selected was the food object and (b) the numerical user input value as blood glucose level when the one of the plurality of touch selectable objects that was touch selected was the blood glucose object.
