Abstract

A portable infusion system that is programmable by an individual for delivering fluid from a reservoir into a user includes a drive mechanism, an input device, a processor, and a display. The drive mechanism forces the fluid out of the reservoir, and the input device accepts one or more inputs. The processor uses one or more of the one or more inputs to control the drive mechanism. The display receives information from the processor and visually displays one or more screens containing the information. At least one of the one or more screens includes a menu with at least two menu items, and the input device is used to select one menu item from amongst the at least two menu items.

12. An infusion system according to claim 1, wherein selection of at least one of the at least two menu items causes the drive mechanism to reverse direction.

13. An infusion system according to claim 1, wherein selection of at least one of the at least two menu items causes the infusion system to begin a selftest.

14. An infusion system according to claim 1, wherein a numeric value displayed in at least one screen has a number to the right of a decimal point that is formatted differently than a number to the left of the decimal point.

15. An infusion system according to claim 1, wherein at least one of the one or more screens is a status screen.

16. An infusion system according to claim 1, wherein the one or more screens includes one or more set screens.

17. An infusion system according to claim 16, wherein the one or more set screens includes a maximum basal rate screen.

18. An infusion system according to claim 16, wherein the one or more set screens includes a maximum bolus screen.

19. An infusion system according to claim 1, wherein the one or more screens includes one or more select screens.

20. An infusion system according to claim 19, wherein the one or more select screens includes a screen to select an insulin type.

21. An infusion system according to claim 19, wherein the one or more select screens includes a screen to select a reservoir type.

22. An infusion system according to claim 19, wherein the one or more select screens includes a screen to select a language.

23. An infusion system according to claim 1, further including a housing that houses the reservoir, the drive mechanism, the input device, the processor, and the display.

24. An infusion system according to claim 23, further including an infusion set and tubing having a first end and a second end, wherein the first end of the tubing is connected to the reservoir and the second end of the tubing is connected to the infusion set.

25. An infusion system according to claim 24, wherein a manual prime may be used to fill the tubing with fluid from the reservoir.

26. An infusion system according to claim 24, wherein a fixed prime may be used to fill the tubing with fluid from the reservoir.

27. An infusion system according to claim 24, wherein information is shown on the display screen to guide the individual through the steps to prime the infusion system.

28. An infusion system according to claim 1, wherein one of the at least two menu items is highlighted when the menu is displayed.

29. An infusion system according to claim 28, wherein the one of at least two menu items that is highlighted when the menu is displayed is dependent on a function that the infusion system is performing when the menu is displayed.

30. An infusion system according to claim 1, further including a communication device.

31. An infusion system according to claim 30, wherein selection of at least one of the at least two menu items causes the display to show a screen that allows an individual to signify the identity of a device, which thereby configures the infusion system to accept communication from the device.
