Abstract

A method of diabetes analysis includes obtaining average glucose level information for a time period over a plurality of days. A current event occurrence is determined. An event occurrence in the average glucose level information within the time period corresponding to the current event occurrence is determined, where the current event occurrence is at a different time of day than the event occurrence. The average glucose level information starting in time from the event occurrence within the time period is analyzed. A notification event in the average glucose level information starting in time from the event occurrence within the time period is determined. A current notification event in time from the current event occurrence is predicted based on a time span from the event occurrence to the notification event in the average glucose level information. An action is initiated in advance of the predicted current notification event.

Claims

1. A method of diabetes analysis, comprising:

obtaining average glucose level information for a time period over a plurality of days;

determining a current event occurrence;

determining an event occurrence in the average glucose level information within the time period corresponding to the current event occurrence, wherein the current event occurrence is at a different time of day than the event occurrence;

analyzing the average glucose level information starting in time from the event occurrence within the time period;

determining a notification event in the average glucose level information starting in time from the event occurrence within the time period;

predicting a current notification event in time from the current event occurrence based on a time span from the event occurrence to the notification event in the average glucose level information; and

initiating an action in advance of the predicted current notification event.

2. The method of claim 1, wherein the current event occurrence is selected from the group consisting of breakfast, lunch, and dinner.

3. The method of claim 1, wherein the event occurrence is selected from the group consisting of breakfast, lunch, and dinner.

4. The method of claim 1, wherein the notification event is selected from the group consisting of hyperglycemia, hypoglycemia, a sharp glucose level spike, and a sharp glucose level drop.

5. The method of claim 1, wherein the action includes at least one of notifying a user of the predicted current notification event, recommending a bolus dosage to the user, automatically delivering a bolus of insulin, and automatically suspending delivery of insulin.

6. The method of claim 5, wherein notifying the user includes an alarm.

7. The method of claim 1, wherein the current event occurrence is earlier or later than the event occurrence in the average glucose level information.

8. The method of claim 1, wherein the method is implemented on a medical system.

9. An article of manufacture containing code for diabetes analysis, comprising a computer-usable medium including at least one embedded computer program that is capable of causing at least one computer to perform:

obtaining average glucose level information for a time period over a plurality of days;

determining a current event occurrence;

determining an event occurrence in the average glucose level information within the time period corresponding to the current event occurrence, wherein the current event occurrence is at a different time of day than the event occurrence;

analyzing the average glucose level information starting in time from the event occurrence within the time period;

determining a notification event in the average glucose level information starting in time from the event occurrence within the time period;

predicting a current notification event in time from the current event occurrence based on a time span from the event occurrence to the notification event in the average glucose level information; and

initiating an action in advance of the predicted current notification event.

10. The article of claim 9, wherein the article is a medical system.

11. The article of claim 9, wherein the current event occurrence is selected from the group consisting of breakfast, lunch, and dinner.

12. The article of claim 9, wherein the event occurrence is selected from the group consisting of breakfast, lunch, and dinner.

13. The article of claim 9, wherein the notification event is selected from the group consisting of hyperglycemia, hypoglycemia, a sharp glucose level spike, and a sharp glucose level drop.

14. The article of claim 9, wherein the action includes at least one of notifying a user of the predicted current notification event, recommending a bolus dosage to the user, automatically delivering a bolus of insulin, and automatically suspending delivery of insulin.

15. The article of claim 14, further including an alarm to notify the user of the predicted current notification event.

16. The article of claim 9, wherein the current event occurrence is earlier or later than the event occurrence in the average glucose level information.
