Abstract

Methods of regulating blood glucose levels using an insulin pump are disclosed. A method includes receiving a current blood glucose level, and determining whether the current blood glucose level is above a threshold value. The method also includes calculating a correction bolus value based upon the current blood glucose.

Claims

1. A method of regulating blood glucose levels using an insulin pump, the method comprising:

receiving a current blood glucose level;

determining whether the current blood glucose level is above a threshold value; and

calculating a correction bolus value based upon the current blood glucose.

2. The method of claim 1, further comprising delivering the correction bolus to the user.

3. The method of claim 1, further comprising:

upon determining that the current blood glucose level is above the threshold value, altering a correction bolus calculation factor;

calculating the correction bolus value using the correction factor.

4. The method of claim 1, further comprising, upon determining that the current blood glucose level is above the threshold value, increasing the correction bolus value by a predefined amount.

5. The method of claim 4, wherein the predefined amount is a percentage of the correction bolus value.

6. The method of claim 5, further comprising prompting a user to input the percentage and the threshold value to define a rule.

7. The method of claim 6, further comprising prompting the user to define a plurality of rules.

8. The method of claim 6, wherein the pump prompts the user.

9. The method of claim 6, wherein a computing system interfaced with the pump prompts the user.

10. The method of claim 4, further comprising displaying the predefined amount on a display of the insulin pump.

11. The method of claim 1, further comprising displaying the correction bolus value on a display of the insulin pump.

12. The method of claim 1, wherein calculating a correction bolus value is further based on an insulin absorption model selected from a plurality of insulin absorption models.

13. An insulin pump comprising:

a pump mechanism;

a memory configured to store one or more blood glucose levels;

a programmable circuit arranged to control the pump mechanism and operatively connected to the memory, the programmable circuit programmed to;

receive a current blood glucose level;

determine whether the current blood glucose level is above a threshold value; and

calculate a correction bolus value based upon the current blood glucose.

14. The insulin pump of claim 13, wherein the programmable circuit is further programmed to deliver the correction bolus to the user.

15. The insulin pump of claim 13, wherein the programmable circuit is further programmed to, upon determining that the current blood glucose level is above the threshold value, alter a correction bolus calculation factor.

16. The insulin pump of claim 15, wherein the programmable circuit is further programmed to calculating the correction bolus value using the correction bolus calculation factor.

17. The insulin pump of claim 13, wherein the programmable circuit is further programmed to, upon determining that the current blood glucose level is above the threshold value, increasing the correction bolus value by a predefined amount.

18. The insulin pump of claim 13, wherein the predefined amount is a percentage of the correction bolus value.

19. The insulin pump of claim 13, wherein the programmable circuit is further programmed to prompt a user to input the percentage and the threshold value to define a rule.

20. The insulin pump of claim 13, wherein the programmable circuit is further programmed to prompt the user to define a plurality of rules.

21. An insulin pump comprising:

a pump mechanism;

a memory configured to store one or more rules, each rule including a threshold and a percentage;

a programmable circuit arranged to control the pump mechanism and operatively connected to the memory, the programmable circuit programmed to;

prompt a user to input the threshold value and the percentage for at least one rule;

receive a current blood glucose level;

determine whether the current blood glucose level is above a threshold value;

upon determining that the current blood glucose level is above the threshold value, alter a correction bolus calculation factor;

calculate a correction bolus value based upon the correction factor; and

deliver the correction bolus to the user.
