Abstract

A pump for delivering insulin to a user comprises a pump mechanism, an alarm and a timer and an alarm program in data communication with the alarm and the timer. The alarm program module is programmed to operate a plurality of types of alerts and to associate a predetermined interval of time and a predetermined event with a selected type of alert. An alarm signal can be generated by the alarm program module based on the predetermined event and interval.

Claims

1. A method of operating an insulin pump, the method comprising:

receiving at the pump a selection of a type of alert from a plurality of types of alerts;

receiving at the pump a predetermined interval of time associated with the selected alert;

associating a predetermined event with the selected alert; and

generating an alarm signal based on the predetermined event and the interval.

2. The method of claim 1 wherein receiving at the pump a predetermined interval of time includes receiving at the pump an end time for the interval.

3. The method of claim 2 wherein receiving at the pump a predetermined interval of time further includes receiving at the pump a start time for the interval.

4. The method of claim 1 wherein the type of alert is a missed meal bolus and the predetermined event is a meal bolus, and generating an alarm signal based on the predetermined event and the interval includes generating an alarm signal if a meal bolus is not delivered during the interval.

5. The method of claim 1, wherein the selected type of alert can be selectively enabled or disabled while being stored in the pump and the alarm signal is only generated if the alert is enabled.

6. The method of claim 1, wherein the type of alert is a glucose reminder and generating an alarm signal based on the predetermined event and the interval includes beginning the interval at the predetermined event and generating a reminder to check a blood glucose level when the interval lapses.

7. The method of claim 1, wherein the type of alert is an automatic off alert and generating an alarm signal based on the predetermined event and the interval includes beginning the interval at the predetermined event and generating alarm indicating that the pump has automatically been shut off when the interval lapses.

8. The method of claim 1, further comprising:

receiving at the pump a selection of a second type of alert from the plurality of types of alerts, the second type of alert being different from the first type of alert;

receiving at the pump a second predetermined interval of time associated with the second selected alert;

receiving at the pump a second predetermined event associated with the second type of alert, the second predetermined event being different from the first predetermined event; and

generating an alarm signal based on the second predetermined event and the second interval.

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

a pump mechanism, an alarm, and a timer;

an alarm program module in data communication with the alarm and the timer, the alarm program module programmed to operate a plurality of types of alerts and to associate a predetermined interval of time and a predetermined event with a selected type of alert, and wherein the alarm program is programmed to generate an alarm signal based on the predetermined event and the interval.

10. The pump of claim 9, wherein the alarm program module is programmed to receive an end time for the interval.

11. The pump of claim 10, wherein the alarm program module is programmed to receive a start time for the interval.

12. The pump of claim 9, further comprising a meal bolus module programmed to control the pump mechanism to deliver a meal bolus, and wherein the type of alert is a missed meal bolus and the predetermined event is a meal bolus, and the alarm program module is programmed to generate the alarm signal if a meal bolus is not delivered by the meal bolus module during the interval.

13. The pump of claim 9, wherein the alarm program module is further programmed to enable each type of alert to be selectively enabled or disabled while being stored.

14. The pump of claim 9, wherein the type of alert is a glucose reminder and the alarm program module is programmed to generate a reminder to check a blood glucose level when the interval lapses.

15. The pump of claim 9, wherein the type of alert is an automatic off alert and the alarm program module is programmed to generate an alarm indicating that the pump has automatically been shut off when the interval lapses.

16. The pump of claim 9, wherein the alarm program module is further programmed to associate a second predetermined interval of time and a second predetermined event with a second selected type of alert, and wherein the alarm program is programmed to generate an alarm signal based on the second predetermined event and the second interval.
