Abstract

A pump for delivering insulin to a user. The pump comprises a pump mechanism and a meal-bolus program module. The meal-bolus program module is programmed to control the pump mechanism to deliver a meal bolus. An alarm program module is in data communication with the alarm, the timer, and the meal-bolus program module. The alarm module is programmed to generate an alarm signal when the meal-bolus program module does not control the pump mechanism to deliver a meal bolus within a predetermined period of time.

Claims

1. A method of operating an insulin pump, the insulin pump configured to selectively deliver a meal bolus, the method comprising:

receiving at the pump a start time for an interval, the start time corresponding to a time of day at which the insulin pump begins monitoring for a meal bolus to be delivered by the insulin pump;

receiving at the pump an end time for the interval, the end time corresponding to a time of day at which the insulin pump stops monitoring for a meal bolus to be delivered by the insulin pump;

storing the start time and end time and associating the interval with a specific missed meal bolus alarm, the missed meal bolus alarm being capable of being selectively enabled and disabled while being stored within the pump; and

generating an alarm signal if the meal bolus is not delivered during the interval when the missed meal bolus alarm is enabled.

2. The method of claim 1, wherein the time of the day of the start time occurs before an expected meal time.

3. The method of claim 1, further comprising receiving a plurality of start times and end times defining a plurality of intervals, and associating each interval with a specific missed meal bolus alarm.

4. The method of claims 3, wherein the missed meal bolus alarms are each capable of being selectively enabled and disabled while being stored with the pump.

5. The method of claim 1, further comprising:

receiving at the pump a selection of another type of alarm to activate other than a missed meal bolus alarm; and

generating the another type of alarm based upon a predetermined event associated with the another type of alarm.

6. The method of claim 1, further comprising:

presenting a menu allowing selection of a missed meal bolus as a standard bolus, extended bolus or combination bolus, wherein the standard bolus delivers the bolus at a maximum rate of the insulin pump, the extended bolus delivers the bolus over an extended period of time at a rate lower than the maximum rate and the combination bolus delivers a portion of insulin at the maximum rate and a portion of insulin over an extended period of time at a rate lower than the maximum rate;

receiving at the pump a selection of the missed meal bolus; and

delivering the missed meal bolus according to the selection.

7. A pump for delivering insulin to a user, the pump comprising:

a pump mechanism, an alarm, and a timer;

a meal bolus program module, the meal bolus program module programmed to control the pump mechanism to deliver a meal bolus; and

an alarm program module in data communication with the alarm, the timer, and the meal-bolus program module, the alarm program module programmed to receive and store a starting time of day and an ending time of day defining an internal for a missed meal bolus alarm and an indication of whether to enable or disable the stored missed meal bolus alarm, the alarm program module further programmed to generate an alarm signal when the meal bolus program module does not control the pump mechanism to deliver a meal bolus within the interval when the missed meal bolus alarm is enabled.

8. The pump of claim 7, wherein the starting time of day occurs before an expected meal time.

9. The pump of claim 7, wherein the alarm module is programmed to receive a plurality of starting times of day and a plurality of ending times of day defining a plurality of intervals for a plurality of missed meal bolus alarms.

10. The pump of claim 9, wherein the alarm program module is further programmed to allow each stored missed meal bolus alarm to be selectively enabled or disabled.

11. The pump of claim 7, further comprising a second alarm program module in data communication with the alarm and the timer, the second alarm program module program programmed to generate an alarm signal for a type of alarm different from the missed meal bolus alarm based on a predetermined event associated with the different type of alarm.

12. The pump of claim 7, wherein the meal bolus program module is programmed to control the pump mechanism to deliver the meal bolus as a standard bolus, an extended bolus or a combination bolus, wherein the standard bolus delivers the bolus at a maximum rate of the pump mechanism, the extended bolus delivers the bolus over an extended period of time at a rate lower than the maximum rate and the combination bolus delivers a portion of insulin at the maximum rate and a portion of insulin over an extended period of time at a rate lower than the maximum rate

13. A method of operating an insulin pump, the insulin pump configured to selectively deliver a meal bolus, the method comprising:

receiving a time at the pump and storing the time with an associated missed meal bolus alarm, the stored missed meal bolus alarm being capable of being selectively enabled and disabled while being stored within the pump; and

generating an alarm signal based on the time if a meal bolus is not delivered when the missed meal bolus alarm is enabled.

14. The method of claim 13, wherein the time is a time of day and generating an alarm signal based on the time includes generating the alarm signal if the time of day occurs without a meal bolus being delivered.

15. The method of claim 13, wherein the time is a length of time and generating an alarm signal based on the time includes generating an alarm if the time lapses without a meal bolus being delivered.

16. The method of claim 13, wherein entering a time into the pump includes defining an interval.

17. The method of claim 16, wherein defining an interval includes entering an end time for the interval.

18. The method of claim 17, wherein defining an interval further includes entering a start time for the interval.

19. The method of claim 18, wherein generating an alarm signal if a meal bolus is not delivered before the time of day occurs includes generating the alarm signal if the meal bolus is not delivered between the start time and the end time.

20. The method of claim 16, wherein generating an alarm signal if a meal bolus is not delivered before the time of day occurs includes generating an alarm signal if a meal bolus is not delivered during the interval.

21. The method of claim 13, further comprising:

receiving at the pump a selection of another type of alarm to activate other than a missed meal bolus alarm; and

generating the another type of alarm based upon a predetermined event associated with the another type of alarm.

22. The method of claim 13, further comprising:

presenting a menu allowing selection of a missed meal bolus as a standard bolus, extended bolus or combination bolus, wherein the standard bolus delivers the bolus at a maximum rate of the insulin pump, the extended bolus delivers the bolus over an extended period of time at a rate lower than the maximum rate and the combination bolus delivers a portion of insulin at the maximum rate and a portion of insulin over an extended period of time at a rate lower than the maximum rate;

receiving at the pump a selection of the missed meal bolus; and

delivering the missed meal bolus according to the selection.
