INTRADERMAL DELIVERY DEVICE INCLUDING A NEEDLE ASSEMBLY

摘要

A drug delivery device including a needle assembly facilitates making intradermal injections using a variety of drug container types such as a syringe. A hub supports the needle while a limiter surrounds the needle. The limiter includes a skin engaging surface that is adapted to be received against the skin of an animal to be intradermally injected. A forward end of the needle extends beyond the skin engaging surface a selected distance to limit a depth that the needle penetrates into the animal's skin.

主权项

1. An intradermal delivery device for use in making intradermal injections, comprising:
a drug container formed of glass having a reservoir adapted to contain a selected substance and an outlet port that allows the substance to exit the reservoir during an injection; a needle having a fixed length wherein said fixed length selected to be suitable for handling during manufacture of said intradermal delivery device; wherein said needle is placed within the outlet port, the needle having a forward end that is adapted to penetrate an the skin of an animal; and an limiter integrally formed on said drug container that is substantially located at a distal end of the needle and said limiter surrounds the needle and is fixed with respect to said outlet port and said limiter has a skin engaging surface that is adapted to be placed against the skin of the animal to receive an intradermal injection, the needle forward end extending away from the skin engaging surface a preselected distance from 0.5 mm to 3.0 mm which is set during manufacture of the intradermal delivery device such that the limiter limits an amount that the needle forward end penetrates the skin which is equivalent to the preselected distance and wherein the preselected distance is substantially less than the needle fixed length.
