Abstract

A method of securing an assembly of a drug delivery system, comprising: configuring at least a first component and a second component of the assembly in a closed configuration ready for placement into the drug delivery system; installing an assembly key including a locking element on the assembly to secure the assembly in said configuration; and, transporting the assembly with the assembly key installed

Claims

1. A method of securing an assembly of a drug delivery system, comprising:

configuring at least a first component and a second component of the assembly in a closed configuration ready for placement into the drug delivery system;

installing an assembly key including a locking element on the assembly to secure the assembly in said configuration; and

, transporting the assembly with the assembly key installed.

2. A method according to claim 1, further comprising employing the assembly key to facilitate assembly of the assembly during manufacture.

3. A method according to claim 1, wherein the transporting is to an end user.

4. A method according to claim 1, further comprising removing the assembly key after transporting.

5. A method according to claim 4, further comprising disposing of the assembly key after removing.

6. A method according to claim 4, wherein the removing is by the end user.

7. A method according to claim 1, wherein the securing includes preventing relative movement of at least two components of the assembly.

8. A method according to claim 1, wherein installing the assembly key includes inserting the locking element of the assembly key through a bit aperture of a first component of the assembly and into a slot, aligned with the bit aperture, of a second component of the assembly, thereby preventing relative movement of the first component and the second component.

9. A method according to claim 1, wherein installing the assembly key includes inserting the locking element of the assembly key through a key aperture of a first component of the assembly and into a key slot, aligned with the key aperture, of a second component of the assembly, thereby preventing relative movement of the first component and the second component.

10. A method according to claim 1, wherein installing comprises removably inserting at least one clip into a first component of the assembly.

11. A method according to claim 10, wherein the at least one clip is installed through the top of the first component.

12. A method according to claim 10, wherein the at least one clip is installed on the outside of the first component.

13. A method according to claim 4, wherein a driver component is the first component and an actuating component is the second component.

14. A method according to claim 13, wherein the driver component includes a gear.

15. A method according to claim 13, wherein the actuating component includes a pushing nut cover configured for pushing a plunger of a syringe.

16. A method according to claim 2, further comprising providing the assembly key with a distinguishing feature to make the assembly key easier to identify for removing.

17. A method according to claim 1, further comprising using the assembly key as a mechanical linkage between the assembly and an assembly machine during manufacture of the assembly key prior to transporting.

18. A method according to claim 17, further comprising using the assembly key to sense the orientation of the assembly during manufacturing.

19. A method according to claim 17, further comprising using the assembly key to screw the assembly into a plunger of the drug delivery system.

20. A method according to claim 7, wherein said installing includes passing a locking bit of the assembly key through a bit aperture in a first of said at least two components and into a key slot of a second of said at least two components.

21. A system for preventing unintended linear extension of an assembly of a drug delivery system during transport, comprising:

an assembly including at least a first component and a second component in a closed configuration; and

,

an assembly key including a locking element removably installed on the closed assembly,

wherein the locking element of the assembly key prevents motion of at least the first component and the second component with respect to each other, thereby preventing extension of the closed assembly during transport.

22. A system according to claim 21, wherein at least the first component and the second component are interconnected by a screw thread and wherein relative rotation of said first and second component causes extension of said assembly.

23. A system according to claim 21, wherein the assembly key includes at least one locking element configured to interplay with at least the first component and the second component such that the two components are prevented from rotating with respect to each other, thereby preventing linear extension of said assembly.

24. A system according to claim 21, wherein the first component of the assembly includes an actuating component for pushing a plunger of the drug delivery system.

25. A system according to claim 24, wherein the first component is provided with a key slot adapted as a counterpart to the locking element.

26. A system according to claim 21, wherein the second component includes a driver component.

27. A system according to claim 26, wherein the second component includes a gear.

28. A system according to claim 21, wherein the second component is provided with a key aperture adapted to the locking element therethrough.

29. A system according to claim 28, wherein the key aperture on the second component aligns with a key slot on the first component to pass the locking element through the first and second components together.

30. A system according to claim 21, wherein the assembly key further comprises at least one clip for removably attaching the assembly key to at least one component of the assembly.

31. A system according to claim 30, further comprising at least one clip aperture provided to the at least one component of the assembly configured as a counterpart to the at least one clip.
