ABSTRACT:
A sterile syringe including a cylindrical housing and a plunger positioned therein movable axially, the housing including a headwall defining a headwall aperture therein which is selectively registrable with a mated aperture defined by a cap member which extends over the head of the syringe, the cap member is mounted upon a stem in the center thereof which secures it to the center of the housing of the syringe, the stem allows relative rotation between the cap member and the syringe housing to selectively align and misalign the aperture in the cap with respect to the aperture in the housing, the end of the cap and the headwall of the housing being slightly spaced from one another to define an insulating space therebetween in which is positioned a sealing member such as a rubber grommet which seals the chamber within the syringe housing whenever the aperture in the headwall of the housing is not aligned with the aperture in the cap due to the cap being rotated slightly with respect to the housing, the aperture in the cap communicating to a nipple which is adapted to receive the needle secured thereto such that movement of the cap by rotation between an opened and a closed position selectively allows or prevents fluid flow communication between the sterile internal chamber and the needle, also possibly including a tab means movable between two protrusions which position the cap member in an opened or closed orientation.
