Abstract

A method and system for both autonomous and manual control of an infusion pump for delivering medication to a patient is provided.

Claims

1. A method of determining a treatment amount for an infusion pump system, comprising:

obtaining treatment information including foodstuff composition information, food on board information, and insulin on board information; and

determining a recommended bolus amount based on the treatment information.

2. The method of claim 1, wherein the step of obtaining treatment information comprises receiving data input from a user of the infusion pump system indicative of at least one of foodstuff composition information, food on board information, and insulin on board information.

3. The method of claim 1, wherein the foodstuff composition information is obtained in response to receiving device-assisted data entry of a foodstuff identification into the infusion pump system.

4. The method of claim 3, wherein the infusion pump system comprises a foodstuff data input device configured to provide said device-assisted data entry of said foodstuff identification.

5. The method of claim 4, wherein the infusion pump system comprises:

a pump body;

a medicine reservoir insertable into an interior space of the pump body through an opening in the pump body;

a drive system positioned in the pump body; and

a control system configured to communicate with the foodstuff data input device.

6. The method of claim 3, wherein the infusion pump system is configured to use the entered foodstuff identification to retrieve foodstuff composition information.

7. The method of claim 6, wherein said foodstuff composition information is retrieved from an onboard data repository of said infusion pump system.

8. The method of claim 6, wherein the foodstuff composition information retrieved by the infusion pump system includes carbohydrate, fat, and protein composition information of a foodstuff.

9. The method of claim 1, wherein the step of determining the recommended bolus amount is based the following equation:

Recommended bolus amount=Food Now*Carb Ratio+(BG−

BGtarget)*insulin sensitivity−

IOB+FOB,

where;

IOB=f(t)*bolus;

FOB=f(t)*grams Carb Ratio+f(t)*grams Protein Ratio+f(t)*grams Fat ratio; and

Food Now=the amount and type of foodstuffs ingested expressed in terms of grams, carbohydrates, proteins or fat.

10. The method of claim 1, wherein the foodstuff composition information comprises a carbohydrate ratio.

11. The method of claim 1, wherein the foodstuff composition information further comprises quantity information.

12. The method of claim 1, wherein the foodstuff composition information comprises carbohydrate, fat, and protein information.

13. The method of claim 1, further comprising using user metabolism information in calculating a bolus amount.

14. The method of claim 13, wherein the user metabolism information comprises insulin sensitivity information.

15. The method of claim 13, wherein the user metabolism information comprises glucose sensitivity information.

16. A method of determining a treatment amount for an infusion pump system,

comprising:

obtaining foodstuff composition information including carbohydrate, fat, and protein composition information of a foodstuff; and

determining a recommended bolus amount based on the foodstuff composition information.

17. The method of claim 16, wherein determining a recommended bolus amount is also based on user metabolism information.

18. The method of claim 16, wherein determining a recommended bolus amount is also based on a user'"'"'s food on board and insulin on board information.

19. The method of claim 16, wherein the foodstuff composition information is obtained in response to receiving device-assisted data entry of a foodstuff identification into the infusion pump system.

20. The method of claim 19, wherein the infusion pump system comprises a foodstuff data input device configured to provide said device-assisted data entry of said foodstuff identification.

21. The method of claim 20, wherein the infusion pump system comprises:

a pump body;

a medicine reservoir insertable into an interior space of the pump body through an opening in the pump body;

a drive system positioned in the pump body; and

a control system configured to communicate with the foodstuff data input device.

22. The method of claim 19, wherein the infusion pump system is configured to use the entered foodstuff identification to retrieve foodstuff composition information.

23. A method of determining a recommended bolus amount, comprising:

obtaining user metabolism information;

obtaining foodstuff composition information including carbohydrate, fat, and protein composition information using device assisted data entry; and

determining a recommended bolus amount using the following equation;

Recommended bolus amount=Food Now*Carb Ratio+(BG−

BGtarget)*insulin sensitivity−

IOB+FOB,

where;

IOB=f(t)*bolus;

FOB=f(t)*grams Carb Ratio+f(t)*grams Protein Ratio+f(t)*grams Fat ratio; and

Food Now=the amount and type of foodstuffs ingested expressed in terms of grams, carbohydrates, proteins or fat.

24. The method of claim 23, wherein the foodstuff composition information is obtained in response to receiving device-assisted data entry of a foodstuff identification into the infusion pump system.

25. The method of claim 24, wherein the infusion pump system comprises a foodstuff data input device configured to provide said device-assisted data entry of said foodstuff identification.

26. The method of claim 25, wherein the infusion pump system comprises:

a pump body;

a medicine reservoir insertable into an interior space of the pump body through an opening in the pump body;

a drive system positioned in the pump body; and

a control system configured to communicate with the foodstuff data input device.

27. The method of claim 24, wherein the infusion pump system is configured to use the entered foodstuff identification to retrieve foodstuff composition information.
