ABSTRACT:
Apparatus for dispensing blood or blood components from a stoppered vial containing such components. The apparatus comprises a combination of a flexible elongated hollow cone, a unitary cap and a dispensing end. The flexible elongated hollow cone tapers from an inlet end to a dispensing end, each end having external threads. The unitary cap is in threaded engagement with the external threads of the inlet end of the cone, with an internal gasket forming an effective seal between the end of the hollow cone and the interior of the unitary cap. The unitary cap has an axial tubular piercing bayonet extending outwardly therefrom with dimensions suitable for penetration of a stopper on a stoppered vial without coring. The dispensing end terminates in a tip with a fluid channel for the dispensing of droplets of liquid from the tip. The dispensing end has a threaded cap in threaded engagement with the external threads on the dispensing end of the cone, such external threads being effective in permitting controlled pressure equalization between the interior of the hollow cone and the atmosphere on removal of the cap.
