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 assembly comprising:
an injector comprising:
a base having an adhesive configured to adhere the injector to a skin surface, and
a fluid reservoir; and

an add-on comprising:
an adaptor comprising at least one Luer lock coupling sized and shaped to couple said adaptor to the fluid reservoir, and
a rigid and bent fluid path having a first end configured to penetrate tissue and a second end coupled to said adaptor,

wherein when said add-on is coupled to said fluid reservoir, sterile fluid communication is secured between said fluid reservoir and said first end of said bent fluid path.

2. The assembly of claim 1 , wherein said bent fluid path comprises a coupling at said second end sized and shaped to couple said bent fluid path to said adaptor and secure sterile fluid communication in-between.

3. The assembly of claim 1 , further comprising at least one fastener sized and fitted to couple said fluid reservoir to the injector.

4. The assembly of claim 1 , wherein said bent fluid path comprises a hollow needle.

5. The assembly of claim 4 , wherein an end of the hollow needle extends beyond the adaptor.

6. The assembly of claim 1 , wherein said bent fluid path is bent at a 90 degree angle.

7. The assembly of claim 1 , wherein said fluid reservoir is a prefilled cartridge.

8. The assembly of claim 1 , wherein said fluid reservoir is a syringe.

9. The assembly of claim 1 , wherein said fluid reservoir is a vial.

10. The assembly of claim 1 , wherein at least a portion of said fluid reservoir is made of glass.

11. The assembly of claim 1 , wherein at least a portion of said fluid reservoir is made of a plastic material.

12. The assembly of claim 1 , wherein said add-on is sterilizable en bloc.

13. The assembly of claim 1 , wherein said adaptor is a vial adaptor.

14. The assembly of claim 1 , further comprising a coupling sized and shaped to couple said add-on to the injector.

15. The assembly of claim 1 , further comprising a cover configured to cover the first end of the bent fluid path.

16. The assembly of claim 1 , further comprising a protective sheath configured to cover the second end of the bent fluid path.

17. The assembly of claim 1 , wherein the injector comprising a plate configured to support the fluid reservoir, wherein the plate is movable relative to the base.
