Abstract

A method for selectively powering a battery-operated drug-delivery device, the device having a battery and a battery circuit, the method comprising: providing a battery isolator in a first position whereat it interrupts a battery circuit, whereby no power is provided to the device; and activating a fastening mechanism configured for fastening the device to a user, the activating causing the battery circuit to be uninterrupted by the isolator, such that power is provided to the device. Additionally, there is provided a selectively powered battery-operated drug-delivery device, comprising: a selectively-removable isolator disposed in a first position whereat it interrupts a battery circuit; the isolator movable to a second position whereat the battery circuit is uninterrupted by the isolator; and a mechanism for fastening the device to a user, activation of the fastening mechanism moving the isolator from the first position to the second position.

Claims

1. A method for selectively powering a battery-operated drug-delivery device, the device having a battery and a battery circuit, said method comprising:

providing a battery isolator disposed in a first position whereat the isolator contacts a battery terminal so as to interrupt the battery circuit, such that no power is provided to the device; and

activating a fastening mechanism of the device, the fastening mechanism configured for fastening the device to the skin of a user, said activating causing movement of the battery isolator to a second position whereat the battery circuit is uninterrupted by the isolator, such that power is provided to the device.

2. A method according to claim 1, wherein the fastening mechanism includes an adhesive surface;

and

said activating includes removing a protective cover from the adhesive surface.

3. A method according to claim 2, wherein said providing includes providing a pre-attached isolator to the protective cover.

4. A method according to claim 2, wherein said providing includes providing the isolator as an extension of the protective cover.

5. A method according to claim 2, wherein the protective cover includes a tab configured to facilitate removal of the protective cover from the adhesive surface;

and

wherein said activating includes pulling the tab so as to remove the protective cover from the adhesive surface.

6. A method according to claim 2, wherein the protective cover includes a single portion configured to cover the adhesive surface;

and

wherein said activating includes removing the protective cover so as to expose the entire adhesive surface.

7. A method according to claim 2, wherein the protective cover includes at least two portions, each portion configured to cover a corresponding portion of the adhesive surface;

said removing including removing a particular one of the at least two portions.

8. A method according to claim 7, wherein the isolator is attached to a particular one of the at least two portions.

9. A method according to claim 1, wherein the device includes a battery chamber and wherein, when the isolator is in said first position, the isolator is at least partially disposed in the battery chamber adjacent at least one of the at least one battery contact.

10. A method according to claim 9, wherein, when the isolator is in said first position, the isolator is at least partially disposed between the at least one battery contact and a corresponding battery terminal of the battery located in the battery chamber;

and

said activating includes removing the isolator from between the at least one battery contact and the corresponding battery terminal of the battery located in the battery chamber.

11. A method according to claim 1, wherein the battery circuit includes at least first and second batteries, said providing including providing the isolator in said first position whereat the isolator prevents a battery contact of the first battery from electrically contacting a battery contact of the second battery;

said activating causing the isolator to be moved to said second position whereat the battery contact of the first battery electrically contacts the battery contact of the second battery.

12. A method according to claim 11, wherein the device includes a battery chamber and wherein, when the isolator is in said first position, the isolator is at least partially disposed in the battery chamber adjacent at least one of the battery contact of the first battery and the battery contact of the second battery.

13. A method according to claim 12, wherein, when the isolator is in said first position, the isolator is at least partially disposed in the battery chamber between the battery contact of the first battery and the battery contact of the second battery;

said activating including removing the isolator from between the battery contact of the first battery and the battery contact of the second battery.

14. A method according to claim 1, said method further comprising:

providing an additional battery isolator disposed in a first position whereat the additional isolator contacts a battery terminal so as to interrupt the battery circuit, such that no power is provided to the device; and

activating an obstruction member of the device, the obstruction member configured for preventing a needle from projecting out of the device, said activating the obstruction member causing movement of the additional battery isolator to a second position whereat the battery circuit is uninterrupted by the additional isolator, such that power is provided to the device when the fastening mechanism is activated.

15. A selectively powered battery-operated drug-delivery device, the device having a battery and a battery circuit, said device comprising:

a selectively-removable isolator, said isolator disposed in a first position whereat said isolator contacts a battery terminal so as to interrupt the battery circuit, such that no power is provided to the device;

said isolator configured to be movable to a second position whereat the battery circuit is uninterrupted by said isolator, such that power is provided to the device; and

a fastening mechanism configured for fastening the device to the skin of a user, said fastening mechanism including a selectively removable portion, said battery isolator extending from said removable portion.

16. A device according to claim 15, said device comprising a housing, said housing including an opening through which said isolator extends when in said first position.

17. A device according to claim 16, wherein said opening comprises a slot.

18. A device according to claim 16, wherein said isolator extends from outside said housing, through said opening.

19. A device according to claim 16, further comprising a protective cover on said fastening mechanism, wherein said isolator extends from said protective cover, through said opening.

20. A device according to claim 19, wherein said fastening mechanism includes an adhesive surface.

21. A device according to claim 19, wherein said isolator is pre-attached to said protective cover.

22. A device according to claim 19, wherein said isolator is an extension of said protective cover.

23. A device according to claim 19, wherein said protective cover includes a tab configured to facilitate removal of the protective cover from said fastening mechanism.

24. A device according to claim 19, wherein said protective cover includes a single portion configured to cover the entire said fastening mechanism.

25. A device according to claim 19, wherein said protective cover includes at least two portions, each portion configured to cover a corresponding portion of said fastening mechanism.

26. A device according to claim 25, wherein each of said at least two cover portions includes a tab configured to facilitate removal of the said cover portion from said fastening mechanism.
