Abstract

An add-on for a self-injector is described. The add-on includes an adaptor having at a rigid and a bent fluid path. The adaptor is sized and fitted to sterilely couple the bent fluid path to a tip of a fluid reservoir. The add-on also includes a fastener sized and fitted to couple a body of the fluid reservoir to the self-injector. The internal diameter of the fastener is adjustable. The adaptor and the fastener couple to the self-injector to at least one of a plurality of reservoirs having different sizes and tip types. The self-injector can include a support plate with a plurality of attachment points. The fastener can be sized and fitted to couple to the body of the fluid reservoir and to at least one of the attachment points. A retention cantilever can releasably couple the at least one fastener to the support plate.

First claim

What is claimed is:

1. A self-injector comprising:
a plate;
an adaptor comprising a rigid and bent fluid path, the adaptor configured to couple the rigid and bent fluid path to a tip of a fluid reservoir;
a fastener configured to couple a body of the fluid reservoir to the plate, an inner diameter of the fastener being adjustable; and
a retention lever configured to couple the fastener to the plate.

2. The self-injector of claim 1 , wherein a distance between the adaptor and the fastener is adjustable.

3. The self-injector of claim 1 , wherein the retention lever is configured to releasably couple the fastener to the plate.

4. The self-injector of claim 1 , wherein the fastener comprises a recess configured to receive the retention lever.

5. The self-injector of claim 1 , wherein the fastener comprises a plurality of recesses configured to receive the retention lever for adjustment of the fastener.

6. The self-injector of claim 1 , where the fastener comprises a pair of legs configured to receive the body of the fluid reservoir therebetween.

7. The self-injector of claim 1 , further comprising a hinge configured to pivotably couple the fastener to the plate.

8. A self-injector comprising:
a support plate having a plurality of attachment points;
an adaptor comprising a rigid and bent fluid path, the adaptor configured to couple the rigid and bent fluid path to at least a tip of a fluid reservoir;
a fastener configured to couple to a body of the fluid reservoir and to at least one of the attachment points; and
a retention cantilever configured to releasably couple the fastener to the support plate.

9. The self-injector of system claim 8 , wherein the adaptor is configured to couple to at least one of the attachment points.

10. The self-injector of system claim 8 , wherein the attachment points are distributed on the support plate at varying distances from the adaptor.

11. The self-injector system claim 10 , wherein the varying distances correspond to varying lengths of the fluid reservoir.

12. The self-injector of system claim 8 , wherein an internal diameter of the fastener is adjustable.

13. The self-injector of system claim 8 , further comprising a fitting configured to fit along an inner surface of the fastener.

14. The self-injector of system claim 13 , wherein the fitting reduces an inner diameter of the fastener.

15. An add-on for a self-injector, the add-on comprising:
an adaptor comprising a rigid and bent fluid path, the adaptor being configured to couple the rigid and bent fluid path to a tip of a fluid reservoir; and
a fastener configured to couple a body of the fluid reservoir to a body of the self-injector, an inner diameter of the fastener being adjustable,
wherein a distance between the adaptor and the fastener is adjustable.

16. The add-on of claim 15 , further comprising a fitting configured to fit along an inner surface of the fastener.

17. The add-on of claim 16 , wherein the fitting reduces an inner diameter of the fastener.

18. The add-on of claim 15 , wherein at least a portion of the fastener is made of a plastic material.

19. The add-on of claim 15 , wherein at least a portion of the fluid reservoir is made of a glass or a plastic material.

20. The add-on of claim 15 , wherein the rigid and bent fluid path comprises a hollow needle.

21. The add-on of claim 15 , wherein the rigid and bent fluid path is bent at a 90-degree angle.

22. The add-on of claim 15 , wherein the fluid reservoir is a prefilled cartridge or a vial.

23. The add-on of claim 15 , wherein the add-on is sterilizable en bloc.

24. The add-on of claim 15 , wherein the adaptor further comprises an adaptor coupling configured to couple the add-on to the self-injector.

25. The add-on of claim 24 , wherein the adaptor coupling is a Luer lock coupling or a vial adapter.

26. The add-on of claim 24 , wherein the adaptor coupling is a slide-on fluid reservoir coupling.

27. An add-on for a self-injector, the add-on comprising:
an adaptor comprising a rigid and bent fluid path, the adaptor being configured to couple the rigid and bent fluid path to a tip of a fluid reservoir;
a fastener configured to couple a body of the fluid reservoir to a body of the self-injector; and
a fitting configured to fit along an inner surface of the fastener,
wherein an inner diameter of the fastener is adjustable.

28. The add-on of claim 27 , wherein the fitting reduces the inner diameter of the fastener.
