Abstract

In accordance with some embodiments of the present invention there is provided a method of preparing a compound device for use. The device may include a sealed component and an active outer surface. The outer surface may be protected by a surface cover. Preparing the device may include activating the active outer surface by removing the surface cover and exposing an internal portion of the sealed component to the exterior of the device by unsealing the sealed component and synchronizing the activating and said unsealing using a coupler attached to the surface cover and the sealed component.

Claims

1. A compound device having an interior volume and an exterior surface comprising:

a wall located between the interior volume and an exterior of the compound device;

a protected component surrounded by an enclosure, said enclosure at least partially located in the interior volume;

a seal for closing said enclosure and for isolating said protected component from said wall;

an active area formed on at least a portion of the exterior surface;

a cover shielding said active area from said exterior; and

,

a coupler attaching said seal to said cover, said coupler synchronizing removal of said cover and unsealing of said enclosure.

2. The compound device of claim 1, further comprising

an opening in said wall exposing said enclosure to said exterior.

3. The compound device of claim 2, wherein said active area is adjacent to said opening.

4. The compound device of claim 2, wherein said coupler connects said seal to said cover via said opening.

5. The compound device of claim 1, wherein said active area includes an adhesive and said cover shields said adhesive.

6. The compound device of claim 1, wherein said protected component includes a hypodermic needle.

7. The compound device of claim 6, wherein said seal includes a needle protective sleeve and wherein said unsealing includes removing said sleeve.

8. The compound device of claim 6, further comprising

an opening in said wall exposing said enclosure to said exterior and wherein said hypodermic needle is directed to protrude through said opening in said wall.

9. The compound device of claim 1, wherein said coupler converts a movement away from the exterior surface into a peeling force on said cover.

10. The compound device of claim 1, wherein said coupler is connected to an edge of said cover.

11. The compound device of claim 1, wherein a volume of said enclosure is smaller than a volume of said interior volume.

12. A method of preparing a device for use, the device including an active outer surface and a protected component isolated from a wall of the device by a sealed enclosure;

the active outer surface protected by a surface cover, the method comprising;

activating the active outer surface by removing the surface cover;

exposing the protected component to the wall of the device by unsealing the sealed enclosure and

synchronizing said activating and said unsealing using a coupler attached to the surface cover and the sealed enclosure.

13. The method of claim 12, wherein said activating includes peeling the surface cover from the active outer surface.

14. The method of claim 13, further comprising:

pulling said coupler away from the surface cover to form a space prior to said peeling.

15. The method of claim 13, wherein the peeling force is applied on an edge of said cover.

16. The method of claim 12, wherein said unsealing includes pulling a needle protective sleeve along an axis of a needle.

17. The method of claim 12, wherein the protected component includes a hypodermic needle, the method further comprising:

projecting said hypodermic needle through an opening in the wall.

18. The method of claim 17, wherein said peeling includes peeling said surface cover from said active surface adjacent to said opening.

19. A method of removing a cap and peeling a cover from a surface comprising:

providing a coupler joining the cap to the cover;

pulling the cap and a portion of the coupler joined thereto away from the surface and

converting of the pulling force on the coupler to a peeling force on the cover of the surface.

20. The method of claim 19, further comprising:

applying said peeling force on an adhered edge of the cover.

21. The method of claim 19, wherein the cap includes a needle protective sleeve and said pulling is along an axis of a needle.

22. The method of claim 19, wherein the cap protects a sterility of a hypodermic needle and the method further comprising:

projecting said hypodermic needle through an opening in the surface.

23. A method of preparing a device for use comprising:

supplying a component of the device sealed by a seal;

protecting an external surface of the device with a cover;

joining said seal to said cover such that breaking seal and removing said cover are synchronized.
