Abstract

A display for use on medical dispensing equipment, and the resulting medical device and its method of display. In particular, provided are a number of specific embodiments of such a display on a medical device, including a film display for use on pill bottles and pill dispensers that utilize colored images as a dosage reminder for the user, a conformable bistable reflective display for use on drug delivery devices, and a conformable bistable reflective display for use on blood glucose meters.

Claims

1. A medication dispensing device comprising:

a container for holding a medication; and

a color display mounted on said container, wherein said display is adapted for providing an indication of a status of said medication utilizing color, such that the color of said display changes to represent a change in the status of said medication.

2. The device of claim 1, wherein said display is a bistable color display provided with a thin, flexible substrate.

3. The device of claim 2, wherein said display conforms to a curve in said container.

4. The device of claim 3, wherein said container includes a cylindrical component, and wherein said display is wrapped around a substantial portion of said cylindrical component.

5. The device of claim 4, wherein said display acts as a label for said device, and wherein said display is attached to said cylindrical component using an adhesive.

6. The device of claim 2, wherein said container includes a removable cap, and wherein said display is provided on said removable cap.

7. The device of claim 1, wherein said display further provides an indication of the status of said medication using alphanumeric or numeric text.

8. The device of claim 7, wherein said color of a status of said medication is reflecting in the color of said text.

9. The method of claim 1, wherein the color of said display is one of yellow, green, blue or red to reflect a first status of said medication, and wherein the color of said display is a different one of yellow, green, blue, or red to reflect a second status of said medication.

10. The device of claim 1, wherein said display utilizes reflected light for viewing said indication without any active backlight.

11. The device of claim 1, wherein said display is a bistable cholesteric color display.

12. A color display adapted for being placed on a medication dispensing device, said display comprising:

a thin, flexible substrate;

an adhesive on said substrate for attaching said display to said medication dispensing device;

a power supply;

at least one layer of electronics provided on said substrate including electronic components for driving said display; and

a plurality of layers provided on said substrate, each one of said layers for displaying a different color, wherein

each one of said layers is comprised of a bistable cholesteric material, such that an image is initially generated for display on said display by using a threshold voltage utilizing said power supply, and wherein said image is subsequently maintained on said display without drawing any substantial current from said power supply.

13. The color display of claim 12, wherein said display is adapted for installation on a removable cap of said medication dispensing device or container.

14. The color display of claim 12, where said display is adapted for installation on a curved surface of said medication dispensing device or container, such that said display conforms to said curved surface.

15. The display of claim 12, wherein the color of said display is one of yellow, green, blue or red to reflect a first status of medication, and wherein the color of said display is a different one of yellow, green, blue, or red to reflect a second status of the medication.

16. The display of claim 12, wherein said display utilizes reflected light reflected off said substrate for viewing said image without any active backlight.

17. A method of displaying a current status of a medication, comprising the steps of:

providing a container for holding said medication;

providing a flexible color display mounted on said container;

determining a first status of said medication;

indicating said first status of said medication using a first color, wherein said first status is viewable utilizing reflected background light without the use of a backlight and wherein said first status is maintained on said display without the consumption of power;

detecting a change in the status of said medication to a second status; and

indicating said second status of said medication using a second color, wherein said second status is also viewable utilizing reflected background light without the use of a backlight and wherein said second status is maintained on said display without the consumption of power.

18. The display of claim 17, wherein said first color is one of yellow, green, blue or red to reflect a first status of medication, and wherein the color of said display is a different one of yellow, green, blue, or red to reflect a second status of the medication.

19. The display of claim 17, wherein power is consumed by said display when initially generating said indication of the first status and when initially generating said indication of the second status.

20. The display of claim 17, wherein said display is mounted on a cap of said container using an adhesive.

21. The display of claim 17, wherein said display is mounted a curved surface of said container using an adhesive, such that said display conforms to said curved surface.

22. A medication dispensing device comprising:

a container for holding a medication;

a sensor or a user input device for obtaining information about a status of the medication; and

a color display mounted on said container, said display including;

a thin, flexible substrate;

an adhesive on said substrate for attaching said display to said medication dispensing device or container;

a power supply;

at least one layer of electronics provided on said substrate including electronic components for driving said display, wherein said electronics is connected to said sensor or said user input device; and

a plurality of layers provided on said substrate, each one of said layers for displaying a different color, wherein

each one of said layers is comprised of a bistable cholesteric material, such that an image is initially generated for display on said display by using a threshold voltage utilizing said power supply, and wherein said image is subsequently maintained on said display without drawing any substantial current from said power supply, and wherein

the color of said display is one of yellow, green, blue, red or a combination thereof to reflect a first status of medication, and wherein the color of said display is changed to a different one of yellow, green, blue, or red, or a different combination thereof to reflect a second status of the medication based on said information obtained by said sensor or said user input device.

23. A medication dispensing device comprising:

a container for holding a medication; and

a bistable color display mounted on said container, wherein

said display is a cholesteric display and is adapted for providing an indication of a first status of said medication utilizing a first color, and wherein

said display is adapted for providing an indication of a second status of said medication utilizing a second color.

24. A method of displaying a current status of a medication, comprising the steps of:

providing a container for holding said medication;

mounting a color cholesteric liquid crystal display on said container, said display including stacked liquid crystal layers or regions in a single liquid crystal layer, each of said layers and said regions being adapted to reflect light of a different color than another of said layers or said regions, respectively;

determining a first status corresponding to;

a first time, or a first amount of medication in said container;

indicating said first status by displaying a first color on said display,

detecting a change in status of said medication to a second status corresponding to;
