Abstract

Described is a medicament container carrier adapted to hold a first medicament container having a first predetermined size and capable of containing more than a first volume of a medicament. The container carrier comprises a body, and an adapter coupled to the body. The adapter is adapted to hold a second medicament container having a second predetermined size different from the first predetermined size and capable of containing no more than the first volume of the medicament.

First claim

The invention claimed is:

1. A medicament container carrier comprising:
a body configured to securely engage a first medicament container to hold the first medicament container directly within the body, the body being configured for removal of the first medicament container from the body, the first medicament container having a first predetermined size and having a first volume capacity that is greater than a first volume of a medicament; and
an adapter adapted to hold a second medicament container having a second predetermined size that is different from the first predetermined size and having a second volume capacity that is no more than the first volume of the medicament,
wherein the adapter is separate from the body and configured to be inserted directly into the body to axially and rotationally fix the adapter to the body when the body is free of the first medicament container.

2. The medicament container carrier of claim 1 , wherein the first volume capacity is approximately 2 mL.

3. The medicament container carrier of claim 1 , wherein the adapter comprises a distal rib adapted to abut a distal end of the second medicament container.

4. The medicament container carrier of claim 1 , wherein the adapter comprises at least one opening providing visual access to the second medicament container.

5. The medicament container carrier of claim 1 , wherein the adapter comprises at least one resilient arm adapted to engage the second medicament container.

6. The medicament container carrier of claim 5 , wherein the at least one resilient arm comprises a first ramp adapted to engage a distal face of a flange of the second medicament container to deflect the at least one resilient arm in a first radial direction.

7. The medicament container carrier of claim 6 , wherein the at least one resilient arm further comprises:
a first abutment surface adapted to engage the flange to prevent rotation of the second medicament container about a longitudinal axis of the adapter relative to the adapter, and
a second abutment surface adapted to engage the flange to prevent axial displacement of the second medicament container relative to the adapter.

8. The medicament container carrier of claim 7 , wherein the at least one resilient arm further comprises:
a second ramp adapted to engage an engagement element on the body to deflect the at least one resilient arm in a second radial direction.

9. The medicament container carrier of claim 8 , wherein the at least one resilient arm further comprises:
a third abutment surface adapted to abut a proximal stop in the body to prevent axial displacement of the adapter relative to the body, and
a fourth abutment surface adapted to engage a restricting surface in the body to prevent rotation of the adapter about a longitudinal axis of the body relative to the body.

10. The medicament container carrier of claim 9 , wherein the proximal stop is formed in an aperture on the body.

11. The medicament container carrier of claim 1 , wherein the first medicament container and the second medicament container are each one of a pre-filled syringe and a medicament cartridge.

12. A medicament delivery device comprising:
a housing; and
a medicament container carrier slidably disposed in the housing the medicament container carrier comprising:
a body configured to securely engage a first medicament container to hold the first medicament container directly within the body, the body being configured for removal of the first medicament container from the body, the first medicament container having a first predetermined size and having a first volume capacity that is greater than a first volume of a medicament, and
an adapter adapted to hold a second medicament container having a second predetermined size that is different from the first predetermined size and having a second volume capacity that is no more than the first volume of the medicament,
wherein the adapter is separate from the body and configured to be inserted directly into the body to axially and rotationally fix the adapter to the body when the body is free of the first medicament container.

13. The medicament delivery device of claim 12 , wherein the first volume capacity is approximately 2 mL.

14. The medicament delivery device of claim 12 , wherein the adapter comprises a distal rib adapted to abut a distal end of the second medicament container.

15. The medicament delivery device of claim 12 , wherein the adapter comprises at least one opening providing visual access to the second medicament container.

16. The medicament delivery device of claim 12 , wherein the adapter comprises at least one resilient arm adapted to engage the second medicament container.

17. The medicament delivery device of claim 16 , wherein the at least one resilient arm comprises:
a first ramp adapted to engage a distal face of a flange to deflect the at least one resilient arm in a first radial direction,
a first abutment surface adapted to engage the flange to prevent rotation of the second medicament container relative to the adapter,
a second abutment surface adapted to engage the flange to prevent axial displacement of the second medicament container relative to the adapter,
a second ramp adapted to engage an engagement element on the body to deflect the at least one resilient arm in a second radial direction,
a third abutment surface adapted to abut a proximal stop in the body to prevent axial displacement of the adapter relative to the body, the proximal stop being formed in an aperture on the body, and
a fourth abutment surface adapted to engage a restricting surface in the body to prevent rotation of the adapter relative to the body.

18. The medicament delivery device of claim 12 , wherein the first medicament container and the second medicament container are each one of a pre-filled syringe and a medicament cartridge, and wherein the medicament delivery device is an auto-injector.

19. A medicament container carrier comprising:
a body configured to securely engage a first medicament container to hold the first medicament container directly within the body, the body being configured for removal of the first medicament container from the body, the first medicament container having a first predetermined size and having a first volume capacity that is greater than a first volume of a medicament; and
an adapter adapted to hold a second medicament container having a second predetermined size that is different from the first predetermined size and having a second volume capacity that is no more than the first volume of the medicament,
wherein the adapter is separate from the body and configured to be inserted directly into the body to couple the adapter to the body when the body is free of the first medicament container,
wherein the adapter comprises at least one resilient arm adapted to engage the second medicament container,
wherein the at least one resilient arm comprises a U-shaped portion, and
wherein the at least one resilient arm is adapted to engage the body.
