Abstract

A personal medical device and method of use with restricted mode challenge having a personal medical device including: a memory operable to store programming code; a processor operably connected to the memory; a user input having input buttons to receive input from the user; and a user display to display output to the user. The processor is operable to: detect a user request for entry to the restricted mode; display a user input image on the user display, the user input image including display buttons corresponding to the input buttons; highlight one of the display buttons; detect actuation of one of the input buttons on the user input; and deny entry to the restricted mode when the one of the input buttons does not correspond to the highlighted display button.

Claims

1. A personal medical device for employment by a user and having a restricted mode, the personal medical device comprising:

a memory operable to store programming code;

a processor operably connected to the memory;

a user input operably connected to the processor and having input buttons to receive input from the user; and

a user display operably connected to the processor to display output to the user;

wherein the processor is responsive to the programming code to;

detect a user request for entry to the restricted mode;

display a user input image on the user display in response to the detected user request, the user input image including display buttons corresponding to the input buttons;

highlight one of the display buttons;

detect actuation of one of the input buttons on the user input; and

deny entry to the restricted mode when the one of the input buttons does not correspond to the highlighted one of the display buttons.

2. The personal medical device of claim 1 wherein the processor is further responsive to the programming code to permit entry to the restricted mode when the one of the input buttons corresponds to the highlighted one of the display buttons.

3. The personal medical device of claim 1 wherein the user request is selected from the group consisting of actuation of an input button on the user input and voice actuation.

4. The personal medical device of claim 1 for use with an infusion set and a reservoir containing a therapeutic fluid, the personal medical device further comprising a fluid driver in fluid communication between the reservoir and the infusion set, the fluid driver being responsive to a flow control signal from the processor to drive the therapeutic fluid from the reservoir to the user through the infusion set.

5. The personal medical device of claim 1 wherein the restricted mode is selected from the group consisting of a basal selection mode and a bolus selection mode.

6. The personal medical device of claim 1 further comprising a user sensor operably connected to the processor and the user to provide a sensed physiological signal from the user.

7. The personal medical device of claim 1 wherein the processor being operable to highlight one of the display buttons further comprises the processor being operable to randomly highlight the one of the display buttons.

8. The personal medical device of claim 1 wherein the user input and the user display are included in a single touch-sensitive display, the input buttons of the user input being touch-sensitive buttons and being aligned with the display buttons of the user display corresponding to the input buttons.

9. A personal medical system for providing a therapeutic fluid to a user, the personal medical system comprising:

a reservoir containing the therapeutic fluid;

a personal medical device having a restricted mode, the personal medical device being operably connected to the reservoir to receive the therapeutic fluid; and

an infusion set operably connected to the personal medical device to receive the therapeutic fluid;

wherein the personal medical device further comprises;

a memory operable to store programming code;

a processor operably connected to the memory;

a user input operably connected to the processor and having input buttons to receive input from the user;

a user display operably connected to the processor to display output to the user; and

a fluid driver in fluid communication between the reservoir and the infusion set, the fluid driver being responsive to a flow control signal from the processor to drive the therapeutic fluid from the reservoir to the user through the infusion set;

wherein the processor is responsive to the programming code to;

detect a user request for entry to the restricted mode;

display a user input image on the user display in response to the detected user request, the user input image including display buttons corresponding to the input buttons;

highlight one of the display buttons;

detect actuation of one of the input buttons on the user input; and

deny entry to the restricted mode when the one of the input buttons does not correspond to the highlighted one of the display buttons.

10. The personal medical system of claim 9 wherein the processor is further responsive to the programming code to permit entry to the restricted mode when the one of the input buttons corresponds to the highlighted one of the display buttons.

11. The personal medical system of claim 9 wherein the user request is selected from the group consisting of actuation of an input button on the user input and voice actuation.

12. The personal medical system of claim 9 wherein the restricted mode is selected from the group consisting of a basal selection mode and a bolus selection mode.

13. The personal medical system of claim 9 further comprising a user sensor operably connected to the processor and the user to provide a sensed physiological signal from the user.

14. The personal medical system of claim 13 wherein the therapeutic fluid is insulin, the personal medical device is an insulin pump, and the user sensor is a glucose monitor.

15. The personal medical system of claim 9 wherein the processor being operable to highlight one of the display buttons further comprises the processor being operable to randomly highlight the one of the display buttons.

16. The personal medical system of claim 9 wherein the user input and the user display are included in a single touch-sensitive display, the input buttons of the user input being touch-sensitive buttons and being aligned with the display buttons of the user display corresponding to the input buttons.

17. A method of use for a personal medical device having a user display and a user input, the user input having input buttons, the method comprising:

detecting a user request for entry to a restricted mode of the personal medical device;

displaying a user input image on the user display in response to the detected user request, the user input image including display buttons corresponding to the input buttons;

highlighting one of the display buttons;

detecting actuation of one of the input buttons on the user input; and

denying entry to the restricted mode when the one of the input buttons does not correspond to the highlighted one of the display buttons.

18. The method of claim 17 further comprising permitting entry to the restricted mode when the one of the input buttons corresponds to the highlighted one of the display buttons.

19. The method of claim 17 wherein the restricted mode is selected from the group consisting of a basal selection mode and a bolus selection mode.

20. The method of claim 17 wherein the highlighting comprises randomly highlighting the one of the display buttons.
