Abstract

A medical therapy system for delivering at least two therapies based on a geographic location of the medical therapy system is disclosed. The medical therapy system includes an infusion pump having a case that contains a processor, memory, a drive mechanism, a reservoir, a radio, and a sensor suite. The sensor suite includes a global positioning system (GPS) receiver to determine a location of the infusion pump. The processor receives the location of the infusion pump and executes first instructions stored in the memory. The processor executes second instructions stored in the memory only when the location of the infusion pump is within a safe zone defined around specified GPS coordinates.

Claims

1. An infusion system comprising:

an infusion pump;

a global positioning system (GPS) receiver; and

a processor configured to execute instructions stored in a memory comprising;

determining a location of the infusion pump via GPS coordinates;

determining whether the location of the infusion pump is within a safe zone defined around specified GPS coordinates, wherein the safe zone is a measured distance around the specified GPS coordinates; and

enabling or disabling one or more functions of the infusion system based on the determining of whether the location of the infusion pump is within the safe zone.

2. The infusion system of claim 1, further comprising a sensor set that provides continuous data of sensor readings to the infusion system.

3. The infusion system of claim 1, further comprising a controller having a user interface and the GPS receiver integrated therein, wherein the controller controls the infusion pump having minimal or no user interface.

4. The infusion system of claim 1, wherein the infusion pump itself includes the GPS receiver and a user interface.

5. The infusion system of claim 1, further comprising a controller wherein both the controller and the infusion pump each include a GPS receiver and a user interface.

6. The infusion system of claim 1, wherein the processor is configured to execute further instructions comprising causing the infusion system to send a prompt for a user to manually activate the one or more functions enabled based on a determination that the location of the infusion pump is within the safe zone.

7. The infusion system of claim 1, wherein the measured distance around the specified GPS coordinates is measured in at least one of feet, meters, or yards.

8. A system comprising:

an infusion pump including a processor, a memory and a sensor suite,

wherein the sensor suite includes a global positioning system (GPS) receiver that determines GPS coordinates of the infusion pump,

wherein the GPS receiver is coupled to the processor that executes first instructions stored in the memory, and wherein the processor executes second instructions stored in the memory in response to determining that the location of the infusion pump is within a safe zone defined around specified GPS coordinates, wherein the safe zone is a measured distance around the specified GPS coordinates.

9. The system of claim 8, further comprising:

a controller for the infusion pump, the controller having a controller processor, controller memory, controller communication suite and controller user interface, the controller communication suite enabling a bi-directional interface between the controller and the infusion pump, the bi-directional interface enabling the controller to modify programming of the infusion pump.

10. The system of claim 8, wherein the first instructions correspond to an approved therapy and the second instructions correspond to a trial therapy.

11. The system of claim 8, wherein if GPS coordinates are unavailable, the infusion pump automatically executes the first instructions.

12. The system of claim 8, wherein storing the second instructions in the memory requires secondary authentication.

13. The system of claim 8, wherein the first instructions disable software updates to the infusion pump and the second instructions enable software updates to the infusion pump.

14. A method for a global positioning system (GPS) enabled infusion system, the method comprising:

determining, electronically by a processor of the GPS enabled infusion system, a location of an infusion pump via a GPS receiver;

determining, electronically by the processor, whether the location of the infusion pump is within a safe zone defined around specified GPS coordinates, wherein the safe zone is a measured distance around the specified GPS coordinates; and

enabling or disabling one or more functions of the GPS enabled infusion system based on the determination of whether the location of the infusion pump is within the safe zone.

15. The method of claim 14, further comprising providing, electronically by the processor, a selection of types of GPS modes.

16. The method of claim 15, wherein the providing the selection further comprises providing a selection of at least one of a clinical trial mode, a parent or guardian mode, or an engineering mode.

17. The method of claim 15, further comprising requiring appropriate authentication for accessing the types of GPS modes.

18. The method of claim 14, further comprising enabling a user to define the specified GPS coordinates and associated user defined safe zones.

19. The method of claim 18, enabling the user to define the safe zone in one or more dimensions including at least one of feet, meters, or yards, from the specified GPS coordinates.

20. The method of claim 14, further comprising enabling a user to load instructions that include defined safe zones for specified GPS coordinates.
