Abstract

An add-on for a self-injector including an adaptor and a bent fluid path is provided. The adaptor includes at least one coupling sized and shaped to couple the adaptor to a fluid reservoir. The bent fluid path is configured at a first end to penetrate tissue and coupled at a second end to the adaptor. The add-on coupled to the fluid reservoir forms an integral self-injector cartridge unit configured to be sterilized and filled with an injectable. The adaptor is configured to couple to a self-injector at least one of a plurality of reservoirs having different sizes and tip types.

First claim

What is claimed is:

1. An add-on for a self-injector comprising:
an adaptor comprising a first coupling at a first end of the adaptor sized and shaped to couple said adaptor to a fluid reservoir, a second coupling at a second end of the adaptor, a first body portion extending from said first coupling, said first body portion being elongate along a first axis, a second body portion extending from said second coupling, said second body portion being elongate along a second axis angularly offset from said first axis, and an elbow portion connecting said first and second body portions;
a rigid and bent fluid path having a first end configured to penetrate tissue and a second end coupled to said adaptor; and
a needle protective cap covering said first end of said fluid path and a protective sheath covering said second end of said fluid path,
wherein said add-on is coupled to said fluid reservoir such that said second end of said fluid path is in fluid communication with said fluid reservoir, and
wherein said add-on coupled to said fluid reservoir forms an integral self-injector cartridge unit configured to be sterilized and filled with an injectable.

2. The add-on according to claim 1 , wherein said fluid path is bent at a 90 degree angle.

3. The add-on according to claim 1 , further comprising at least one fastener sized and fitted to couple a body of said fluid reservoir to a self-injector.

4. The add-on according to claim 3 , an internal diameter of the at least one fastener being adjustable;
wherein said adaptor and said fastener are configured to couple to said self-injector at least one of a plurality of reservoirs having different sizes and tip types.

5. The add-on according to claim 4 , wherein the distance between said adaptor and said fastener is adjustable.

6. The add-on according to claim 4 , wherein said plurality of reservoirs include fluid reservoirs.

7. The add-on according to claim 3 , wherein the add-on further comprises a fitting sized and shaped to fit along the inner circumference of said at least one fastener.

8. The add-on according to claim 7 , wherein said fitting reduces the inner diameter of said at least one fastener.

9. The add-on according to claim 3 , wherein at least a portion of said at least one fastener is made of a plastic material.

10. The add-on according to claim 1 , wherein said second coupling is sized and shaped to couple said bent fluid path to said adaptor and secure sterile fluid communication in-between.

11. The add-on according to claim 1 , wherein said bent fluid path comprises a hollow needle.

12. The add-on according to claim 1 , wherein said reservoir is a prefilled cartridge.

13. The add-on according to claim 1 , wherein said reservoir is a syringe.

14. The add-on according to claim 1 , wherein said reservoir is a vial.

15. The add-on according to claim 1 , wherein at least a portion of said reservoir is made of glass.

16. The add-on according to claim 1 , wherein at least a portion of said reservoir is made of a plastic material.

17. The add-on according to claim 1 , wherein said add-on is sterilizable en bloc.

18. The add-on according to claim 1 , wherein said at least one coupling is a vial adaptor.

19. The add-on according to claim 1 , wherein said second coupling is sized and shaped to couple said add-on to a self-injector.

20. The add-on according to claim 1 , wherein said first coupling is a Luer lock coupling.

21. The add-on according to claim 1 , wherein said at least one coupling is a slide-on fluid reservoir coupling.

22. A self-injector coupling system comprising
a self-injector comprising a support plate with a plurality of attachment points;
the add-on according to claim 1 ; and
at least one fastener sized and fitted to couple to a body of said fluid reservoir and to at least one of said attachment points; and
a retention cantilever configured to releasably couple said at least one fastener to said support plate.

23. The system according to claim 22 , wherein said adaptor is sized and fitted to couple to at least one of said attachment points.

24. The system according to claim 22 , wherein said attachment points are distributed on said support plate at varying distances from said adaptor.

25. The system according to claim 22 , wherein said varying distances correspond to varying lengths of said fluid reservoir.

26. A self-injector kit, comprising
at least one self-injector comprising a support plate with a plurality of attachment points;
a plurality of the add-ons according to claim 1 ; and
a plurality of fasteners sized and fitted to couple to at least one diameter of a body of said fluid reservoir and to at least one of said attachment points;
a plurality of retention cantilevers configured to releasably couple said plurality of fasteners to said support plate.

27. The kit according to claim 26 , wherein at least one of said adaptors is sterile.

28. A method of assembling an add-on for a self-injector comprising:
selecting an empty fluid reservoir;
forming the integral self-injector cartridge unit by coupling at least a tip of said fluid reservoir to the add-on according to claim 1 ; and
establishing fluid communication between said fluid reservoir and said bent fluid path.

29. The method according to claim 28 , further comprising
sterilizing said cartridge unit;
filling said fluid reservoir with a sterile injectable;
inserting a plunger into an non-bent fluid path end of said fluid reservoir; and
sterilely sealing said end of said fluid reservoir.

30. The method according to claim 28 , further comprising selecting at least one fastener and coupling said fastener to a body of said fluid reservoir; and
coupling said fastener to at least one corresponding attachment point on said injector.

31. A method of coupling an add-on for a self-injector to a fluid reservoir comprising:
selecting a fluid reservoir;
coupling at least a tip of said fluid reservoir to the add-on according to claim 1 ; and
establishing sterile communication between said fluid reservoir and said bent fluid path.

32. The method according to claim 31 , further comprising selecting at least one fastener and coupling said fastener to a body of said fluid reservoir; and
