Abstract

An intradermal needle assembly that is attachable to a prefillable container intended for intradermally injecting substances into an animal includes a needle cannula supported by a hub portion. The hub portion is adapted to receive the prefillable container just prior to administering the intradermal injection. A limiter portion surrounds the needle cannula and extends away from the hub portion toward a forward tip of the needle cannula, and includes a skin engaging surface with the needle cannula having a fixed angle of orientation, preferably generally perpendicular, relative to the plane of the skin engaging surface. The skin engaging surface is received against the skin of an animal to administer an intradermal injection. The forward tip extends beyond the skin engaging surface a distance enabling penetration of the needle cannula into the dermis layer of the skin of the animal enabling injection of the substance into the dermis layer.

Claims

1. An intradermal needle assembly for use with a prefillable container having a reservoir capable of storing a substance for injection into the skin of an animal comprising:

a hub portion provided on the prefillable container;

a needle cannula supported by said hub portion and having a forward tip extending away from said hub portion; and

a limiter portion surrounding said needle cannula and extending away from said hub portion toward said forward tip of said needle cannula, said limiter including a generally flat skin engaging surface extending in a plane generally perpendicular to an axis of said needle cannula and adapted to be received against the skin of the animal to administer an intradermal injection of the substance, said hub portion and said limiter portion being formed as separate pieces, said limiter portion and said needle cannula being non-movable with respect to each other such that said needle cannula forward tip extends beyond said skin engaging surface a distance ranging from approximately 0.5 mm to 3.0 mm and wherein said limiter portion limits penetration of the needle into the dermis layer of skin of the animal so that the substance is injected into the dermis layer of the animal, said limiter portion defining an inner cavity receiving at least a portion of said hub and including an abutment engaging a corresponding structure on said hub portion thereby limiting the length of said needle cannula extending beyond said skin engaging surface.

2. The assembly as set forth in claim 1 wherein said hub portion includes a throat for receiving the prefillable container.

3. The assembly as set forth in claim 2 wherein said needle cannula is fixedly attached to said hub portion.

4. The assembly as set forth in claim 3 wherein said needle cannula is fixedly attached to said hub portion with an adhesive.

5. The assembly as set forth in claim 4 wherein said adhesive comprises an epoxy curable with ultra violet light.

6. The assembly as set forth in claim 5 wherein said limiter portion includes a plurality of snaps engaging said hub portion thereby fixedly attaching said hub portion to said limiter portion.

7. The assembly as set forth in claim 1 wherein said substance includes an influenza vaccine.

8. The assembly as set forth in claim 1 wherein said needle assembly is attachable to a prefillable container with a Luer fit.

9. An intradermal needle assembly for use with a prefillable container having a reservoir capable of storing a substance for injection into the skin of an animal comprising:

a hub portion having a throat for receiving the prefillable container;

a needle cannula being supported by said hub portion and having a forward tip extending away from said hub portion;

a limiter portion surrounding said hub portion and said needle cannula and extending away from said hub portion toward said forward tip of said needle, said limiter portion including a generally flat skin engaging surface extending in a plane generally perpendicular to an axis of said needle cannula and being adapted to be received against the skin of an animal to receive an intradermal injection of the substance, said hub portion and said limiter portion being formed as separate pieces, said limiter portion and said needle cannula being non-movable with respect to each other such that said forward tip extends beyond the skin engaging surface a distance ranging from approximately 0.5 mm to approximately 3.0 mm and wherein the limiter portion limits penetration of said needle cannula into the dermis layer of the skin of the animal thereby injecting the substance into the dermis layer of the animal, said limiter portion defining an inner cavity receiving at least a portion of said hub and including an abutment engaging a corresponding structure on said hub portion thereby limiting the length of said needle cannula extending beyond said skin engaging surface.

10. The assembly as set forth in claim 9 wherein said needle cannula is fixedly attached to said hub portion.

11. The assembly as set forth in claim 10 wherein said needle cannula is fixedly attached to said hub portion with an adhesive.

12. The assembly as set forth in claim 11 wherein said adhesive comprises an epoxy curable with ultra violet light.

13. The assembly as set forth in claim 9 wherein said limiter portion includes a plurality of snaps engaging said hub portion thereby fixedly attaching said hub portion to said limiter portion.

14. The assembly as set forth in claim 9 wherein said substance includes an influenza vaccine.

15. The assembly as set forth in claim 9, wherein said needle assembly is attachable to a prefillable container with a Luer fit.
