Vial adapter and system
A vial adapter includes a base having first and second opposing sides, a spike depending from the first side of the base, the spike having a spike passageway, and a connector disposed on the second side of the base, the connector having a connector passageway that is in fluid communication with the spike passageway. The vial adapter may be combined with a vial.
1. A system comprising:
a vial having a neck with a passage in the neck and a rim disposed adjacent the neck, a stopper disposed over the passage in the neck of the vial to control access through the passage into the vial, and a crimp ring disposed about the stopper and the rim to maintain the stopper fixed relative to the vial;
a vial adapter including:
a collar securely attached to the vial at the neck of the vial and having a continuous inner circumferential surface engaging the neck of the vial, the collar for receiving one of a pair of opposing axial forces to limit the movement of the stopper relative to the vial,
a plate for receiving another of the pair of axial opposing forces, the plate being axially spaced apart from the collar, and
a surface of the crimp ring abutting a surface of the collar and an opposite surface of the crimp ring abutting a surface of the plate; and
a spike configured to be advanced through a passage in the plate and penetrate the stopper after the collar is securely attached to the vial.
2. The system according to claim 1 , wherein the collar comprises first and second C-shaped sections that are joined at opposing ends by one or more fasteners.
3. The system according to claim 2 , wherein the one or more fasteners are mating hooks.
4. The system according to claim 1 , wherein the collar comprises first and second sections joined by a hinge at one pair of ends and by one or more fasteners at another pair of ends.
5. The system according to claim 4 , wherein the hinge is a living hinge and the one or more fasteners are a tongue and groove fastener.
6. The system according to claim 1 , wherein the inner circumferential surface of the collar is shaped to match a contour of a shoulder defining the neck of the vial and a contour of an outer surface of the crimp ring such that the collar fills the neck.
7. A method of operating a system comprising:
applying a force to a collar securely attached to a vial having a neck with a passage in the neck and a rim disposed adjacent the neck, a stopper disposed over the passage in the neck of the vial to control access through the passage into the vial, and a crimp ring disposed about the stopper and the rim to maintain the stopper fixed relative to the vial, the collar securely attached to vial at the neck of the vial; and
applying an opposing axial force to a plate, the plate being axially spaced from the collar, a surface of the crimp ring abutting a surface of the collar and an opposite surface of the crimp ring abutting a surface of the plate.
8. The method of operating a system according to claim 7 , further comprising advancing a spike into the stopper associated with the vial.
9. The method of operating a system of claim 7 , a portion of the crimp ring being positioned between the stopper and the plate.
10. The method of operating a system according to claim 7 , comprising advancing a needle through the stopper and into the vial while applying the force to the collar and applying the opposing force to the plate.
