Abstract
Abstract A picerceable access port for parenteral solution containers, including a flexible plastic tube communicating at one end with the interior of the container and closed at its other end to seal the container. A gripping sleeve is positioned about the flexible plastic tube so that the free end of the plastic tube is positioned within the bore of the sleeve. By this arrangement, the free end of the flexible tube defines a puncturable diaphragm within the gripping sleeve accessible to a piercing spike passing through the sleeve to gain access to the container.
