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.
