Abstract

A medical therapy system to deliver a pre-bolus volume of medicant is disclosed. The medical therapy system includes an infusion pump that has a case containing a processor, memory, a drive mechanism, a reservoir, communication hardware and a sensor system. The infusion pump further includes a global positioning system (GPS) receiver to determine GPS coordinates of the infusion pump. The GPS receiver is coupled to the processor that executes stored program instructions to provide notification for confirmation to deliver a pre-bolus volume from the reservoir when the GPS coordinates of the infusion pump are within a specified proximity of GPS coordinates of a saved location.

Claims

1. A medical therapy system to deliver a pre-bolus volume of medicant, the medical therapy system comprising:

an infusion pump having a case, the case containing a processor, memory, a drive mechanism, a reservoir, and communication hardware;

the infusion pump further including a global positioning system (GPS) receiver to determine GPS coordinates of the infusion pump, the GPS receiver being coupled to the processor, the processor executing stored program instructions to provide notification for confirmation to deliver a pre-bolus volume from the reservoir when the GPS coordinates of the infusion pump are within a specified proximity of GPS coordinates of a known location.

2. The medical therapy system as defined in claim 1, wherein the known location is stored in the memory of the infusion system.

3. The medical therapy system as defined in claim 2, wherein known locations are created by recording the GPS coordinates, time and bolus volume for any bolus delivery by the infusion pump.

4. The medical therapy system as defined in claim 2, wherein a user inputs a known location into the memory of the infusion system.

5. The medical therapy system as defined in claim 1, wherein the known location is accessed via a third-party database.

6. The medical therapy system as defined in claim 1, wherein a threshold value is required before requesting confirmation of delivery of a pre-bolus volume.

7. The medical therapy system as defined in claim 6, wherein the threshold value is time of day.

8. The medical therapy system as defined in claim 7, wherein the time of day threshold is user configurable with a plurality of values.

9. The medical therapy system as defined in claim 8, wherein the time of day threshold values are automatically determined by repetition of times of previous bolus deliveries.

10. The medical therapy system as defined in claim 6, wherein the threshold value is a number of restaurants within a proximity of the GPS coordinates of the infusion pump.

11. The medical therapy system as defined in claim 10, wherein the proximity of the GPS coordinates of the infusion pump is user configurable.

12. The medical therapy system as defined in claim 11, wherein the number of restaurants is reported by a third party application, the third party application providing classifications for the number of restaurants.

13. The medical therapy system as defined in claim 12, wherein user configurable filters based on the provided classifications reduce the number of restaurants to a preferred selection of restaurants.

14. The medical therapy system as defined in claim 1, wherein the pre-bolus volume is determined from previous bolus deliveries.

15. The medical therapy system as defined in claim 14, wherein the previous bolus deliveries used to determine the pre-bolus volume are selected from previous bolus deliveries performed at substantially a same time and within close proximity to similar GPS coordinates.

16. The medical therapy system as defined in claim 1, wherein if confirmation to deliver the pre-bolus is not received in a specified period of time the pre-bolus is automatically canceled, the specified period of time being configurable.

17. The medical therapy system as defined in claim 1, wherein if confirmation to deliver the pre-bolus is not received in a specified period of time the pre-bolus is automatically delivered, the specified period of time being configurable.

18. The medical therapy system as defined in claim 1, wherein confirmation to deliver the pre-bolus is received via voice recognition.

19. The medical therapy system as defined in claim 1, further including an option to modify the pre-bolus volume before confirming delivery.

20. The medical therapy system as defined in claim 1, furthering including an option to delay the delivery of the pre-bolus by a user specified period of time.
