Abstract

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

Claims

1. An infusion pump for delivering medicament to a user, the pump comprising:

a pump mechanism, an alarm, and a timer;

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

an alarm program module in data communication with the alarm, the timer, and the 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 interval for a missed bolus alarm and an indication of whether to enable or disable the stored missed bolus alarm, the alarm program module further programmed to generate an alarm signal when the bolus program module does not control the pump mechanism to deliver a bolus of the medicament within the interval when the missed bolus alarm is enabled.

2. The pump of claim 1, wherein the alarm program 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 bolus alarms.

3. The pump of claim 2, wherein the alarm program module is further programmed to allow each stored missed bolus alarm to be selectively enabled or disabled.

4. The pump of claim 1, 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 bolus alarm based on a predetermined event associated with the different type of alarm.

5. The pump of claim 1, wherein the bolus program module is programmed to control the pump mechanism to deliver the 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 the bolus at the maximum rate and a portion of the bolus over an extended period of time at a rate lower than the maximum rate.

6. The pump of claim 1, wherein the bolus is a missed meal bolus.

7. The pump of claim 6, wherein the starting time of day occurs before an expected meal time.

8. The pump of claim 6, wherein the medicament is insulin.

9. The pump of claim 1, wherein the medicament is insulin.

20. The pump of claim 9, wherein the medicament is insulin.

10. An infusion pump for delivering medicament to a user, the pump comprising:

a pump mechanism, an alarm, and a timer;

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

an alarm program module in data communication with the alarm, the timer, and the bolus program module, the alarm program module programmed to receive and store a time as associated with a missed bolus alarm and an indication of whether to enable or disable the stored missed bolus alarm, the alarm program module further programmed to generate an alarm signal based on the time when the bolus program module does not control the pump mechanism to deliver a bolus of medicament when the missed bolus alarm is enabled.

11. The pump of claim 10, wherein the time is a time of day and the alarm program module is programmed to generate the alarm signal if the time of day occurs without a bolus being delivered by the bolus program module.

12. The pump of claim 10, wherein the time is a length of time and the alarm program module is programmed to generate the alarm signal if the length of time lapses without a bolus being delivered by the bolus program module.

13. The pump of claim 10, wherein the time is an interval and the alarm program module is programmed to generate the alarm signal if a bolus is not delivered by the bolus program module during the interval.

14. The pump of claim 13, wherein the interval is defined by a start time and an end time.

15. The pump of claim 10, wherein the alarm program module is programmed to receive and store a plurality of times each being associated with one of a plurality of missed bolus alarms.

16. The pump of claim 11, wherein the alarm program module is further programmed to allow each stored missed bolus alarm to be selectively enabled or disabled.

17. The pump of claim 10, 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 bolus alarm based on a predetermined event associated with the different type of alarm.

18. The pump of claim 10, wherein the bolus program module is programmed to control the pump mechanism to deliver the 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 the bolus at the maximum rate and a portion of the bolus over an extended period of time at a rate lower than the maximum rate.

19. The pump of claim 10, wherein the bolus is a missed meal bolus.

21. The pump of claim 10, wherein the medicament is insulin.
