PREFILLABLE INTRADERMAL DELIVERY DEVICE

摘要

An intradermal delivery device for use in intradermally injecting substances into the skin of an animal includes a needle cannula supported by a hub portion (22) that is attachable to a prefillable container (12). A limiter portion (24) surrounds the needle cannula and extends away from the hub portion toward a forward tip of the needle cannula. The limiter portion includes a skin engaging surface (26) extending in a plane generally perpendicular to an axis of the needle cannula. The skin engaging surface is received against skin of an animal to administer an intradermal injection. The forward tip extends beyond the skin engaging surface a distance that enables penetration of the needle cannula into the dermis layer of the skin of the animal enabling injection of the substance into the dermis layer of the animal. The device includes enclosure means (24,82,112) that is moveable for concealing the needle cannula after the injection has been administered.
