Needle protection device for use with a vial
First Claim
1. For use with a vial having a body, a neck extending from said body and a needle extending from said neck, an apparatus for preventing said needle from being exposed to the environment, comprising:
- a housing for enveloping said needle, said housing having a collar that is configured to fit to said vial, said collar having a portion that clamps about said body of said vial and an extension that fits about at least a portion of the neck of said vial.

Abstract
A needle protection device for a vial, or capsule, has a housing hingedly or flexibly connected to a needle collar by a hinge. The collar has a main portion configured to fit about at least a portion of the body of the vial and an extension configured to fit about at least a portion of the neck of the vial. A needle hub, movable along the neck of the vial and to which a needle extends, is interposed between the body and neck of the vial. The hub has a skirt portion that could be moved along the neck of the vial for capping or overlapping the extension of the collar to thereby non-removably secure the collar to the vial. An improved syringe assembly is effected when a vial of the instant invention is placed within a vial holder applicator, such as for example a CARPUJET applicator. Once firmly positioned within the applicator, a mechanism integral to the applicator is actuated to move the skirt portion of the hub and the collar extension that fits about the neck of the vial relatively towards each other so that the collar extension is capped by the hub skirt portion, thereby securely coupling the collar to the vial. A rod movable along the length of the applicator is mated with a plunger movable along the body of the vial to effect the syringe assembly. The housing hingedly connected to the collar is pivotable relative to the vial to envelop the needle extending from the hub, thereby ensuring that the needle, once contaminated, is prevented from being further exposed.

6. A method of attaching a needle protection housing to a vial having a body, a neck extending from said body and a needle extending from said neck, comprising the steps of:
-
a) integrating a collar to said housing, said collar having a portion that clamps about the body of said vial and an extension that fits about at least a portion of said neck of said vial;
b) securing said housing to said vial by means of said collar;
c) interposing a hub between said neck and said needle of said vial, said hub having a skirt portion that is movable along said neck of said vial; and
d) moving said hub to position said skirt portion to overlap said extension of said collar to thereby fixedly couple said collar to said vial. - View Dependent Claims (7, 8, 9)

10. A syringe assembly comprising:
-
a vial having a body, a neck extending from said body and a needle extending from said neck;
a housing for enveloping said needle, said housing having a collar that is configured to fit to said vial, said collar having a portion that clamps about at least a portion of said body of said vial and an extension that fits about at least a portion of said neck of said vial; and
a holder whereinto said vial is placed, said holder having one end for biasing against said neck of said vial and a mechanism for applying a biasing force against an other end of the body of said vial away from said neck, said mechanism being actuable to apply a force to push the body of said vial towards said one end of said holder to thereby fixedly couple said extension of said collar to said vial. - View Dependent Claims (11, 12, 13, 14, 15)
