Abstract

Enhanced confirmations for programming of touchscreen infusion pumps reduce the likelihood of users confirming pump parameters that have been mistakenly programmed. Following programming of a given pump parameter, an icon or image intuitively related to the pump parameter can be displayed on the touchscreen. To confirm programming of the parameter, the user can be required to trace the icon on the touchscreen. The user will therefore necessarily associate the confirmation step with the parameter being programmed and be far more likely to realize if a mistake has been made because the user was intending to program a different parameter than with simple confirmations involving the press of a confirmation button.

Claims

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

displaying a bolus setup page on a touch-screen display of a portable infusion pump system;

receiving a user entry of a value for a pump parameter for calculation of a bolus of medicament to be delivered to the user via the bolus setup page;

displaying a confirmation screen on the touch-screen display requiring a confirmation of the user entry, including displaying a pictorial icon representing the pump parameter;

identifying a user interaction with the touch-screen display as the user providing the confirmation by tracing an outline of the pictorial icon; and

causing the portable infusion pump to deliver the bolus of medicament to the user only after identifying the confirmation of the user tracing the outline of the pictorial icon.

2. The method of claim 1, further comprising displaying a text confirmation of the value and the pump parameter adjacent to the pictorial icon on the confirmation screen.

3. The method of claim 1, further comprising displaying instructions to the user on the confirmation screen instructing the user to trace the pictorial icon to provide the confirmation.

4. The method of claim 1, wherein the pump parameter is an amount of carbohydrates.

5. The method of claim 4, wherein the pictorial icon is a food item.

6. The method of claim 1, wherein the pump parameter is a blood glucose level.

7. The method of claim 1, wherein the pump parameter is an amount of medicament.

8. The method of claim 1, further comprising:

receiving a second user entry of a value for a second pump parameter for calculation of the bolus of medicament to be delivered to the user via the bolus setup page;

displaying a second confirmation screen on the touch-screen display requiring a confirmation of the second user entry, including displaying a second pictorial icon representing the second pump parameter; and

identifying a user interaction with the touch-screen display as the user providing the second confirmation by tracing an outline of the second pictorial icon, wherein

causing the portable infusion pump to deliver the bolus of medicament to the user only after identifying the confirmation of the user tracing the outline of the pictorial icon includes only causing the portable infusion pump to deliver the bolus after identifying both the confirmation of the user entry and the second confirmation of the second user entry.

9. The method of claim 8, wherein the second pictorial icon representing the second pump parameter is different from the pictorial icon representing the pump parameter.

10. The method of claim 1, further comprising:

calculating a bolus amount for the bolus based on the value of the pump parameter;

displaying a bolus amount confirmation screen on the touch-screen display requiring a bolus confirmation of the bolus amount, including displaying a pictorial icon representing the bolus; and

identifying a user interaction with the touch-screen display as the user providing the bolus confirmation by tracing an outline of the pictorial icon representing the bolus, wherein

causing the portable infusion pump to deliver the bolus of medicament to the user only after identifying the confirmation of the user tracing the outline of the pictorial icon includes only causing the portable infusion pump to deliver the bolus after identifying both the confirmation of the user entry and the bolus confirmation of the bolus amount.

11. A portable infusion pump, comprising:

a reservoir configured to contain a medicament;

a pumping mechanism configured to deliver medicament from the reservoir to a user;

a user interface including a touch-screen display;

a processor programmed to;

display a bolus setup page on the touch-screen display;

receive a user entry of a value for a pump parameter for calculation of a bolus of medicament to be delivered to the user via the bolus setup page;

display a confirmation screen on the touch-screen display requiring a confirmation of the user entry, including displaying a pictorial icon representing the pump parameter;

identify a user interaction with the touch-screen display as the user providing the confirmation by tracing an outline of the pictorial icon; and

cause the pumping mechanism to deliver the bolus of medicament to the user only after identifying the confirmation of the user tracing the outline of the pictorial icon.

12. The portable infusion pump of claim 11, where the processor is further programmed to display a text confirmation of the value and the pump parameter adjacent to the pictorial icon on the confirmation screen.

13. The portable infusion pump of claim 11, where the processor is further programmed to display instructions to the user on the confirmation screen instructing the user to trace the pictorial icon to provide the confirmation.

14. The portable infusion pump of claim 11, wherein the pump parameter is an amount of carbohydrates.

15. The portable infusion pump of claim 14, wherein the pictorial icon is a food item.

16. The portable infusion pump of claim 11, wherein the pump parameter is a blood glucose level.

17. The portable infusion pump of claim 11, wherein the pump parameter is an amount of medicament.

18. The portable infusion pump of claim 11, where the processor is further programmed to:

receive a second user entry of a value for a second pump parameter for calculation of the bolus of medicament to be delivered to the user via the bolus setup page;

display a second confirmation screen on the touch-screen display requiring a confirmation of the second user entry, including displaying a second pictorial icon representing the second pump parameter; and

identify a user interaction with the touch-screen display as the user providing the second confirmation by tracing an outline of the second pictorial icon, wherein

causing the portable infusion pump to deliver the bolus of medicament to the user only after identifying the confirmation of the user tracing the outline of the pictorial icon includes only causing the portable infusion pump to deliver the bolus after identifying both the confirmation of the user entry and the second confirmation of the second user entry.

19. The portable infusion pump of claim 18, wherein the second pictorial icon representing the second pump parameter is different from the pictorial icon representing the pump parameter.

20. The portable infusion pump of claim 11, where the processor is further programmed to

calculate a bolus amount for the bolus based on the value of the pump parameter;

display a bolus amount confirmation screen on the touch-screen display requiring a bolus confirmation of the bolus amount, including displaying a pictorial icon representing the bolus; and

identify a user interaction with the touch-screen display as the user providing the bolus confirmation by tracing an outline of the pictorial icon representing the bolus, wherein

causing the portable infusion pump to deliver the bolus of medicament to the user only after identifying the confirmation of the user tracing the outline of the pictorial icon includes only causing the portable infusion pump to deliver the bolus after identifying both the confirmation of the user entry and the bolus confirmation of the bolus amount.
