Abstract: The present invention comprehends the provision of a fluid tight holding chamber which accumulates solution from the vial that aspirates during mixing or drawing fluid from the vial or is pressured out of the syringe upon extraction of the cannula from the vial. The holding chamber is defined in conjunction with the vial septum by a shield cap that surrounds and seals to the neck of the vial. The shield cap defines a guide for the cannula of the syringe and directs the cannula through a sealing member, the holding chamber, the septum and into the vial. One aspect of the invention provides a sleeve portion on the shield cap that receives and retains the syringe barrel. An arm is provided on the sleeve portion and has a notch that holds the syringe barrel in a predetermined position during shipment and storage of the assembly.

Furthermore, the invention is also directed to an injection site of the type described herein which is especially adapted for use as an injection port of a Y-connector utilized for an intravenous administration set. The device incorporates a self-sealing puncturable member of resilient material, such as rubber, which member is of a substantially spheroid configuration, the tubular segment so as to be in close proximity to the and which is swage-molded into a receiving housing in the tubular segment so as to be in close proximity to the inlet tubing for the flow path of the parenteral fluid.

Abstract: A valving-type closure having a resilient diaphragm provided with a portion having a through slit for the passage of fluids, the slit portion being adapted to bulge and open the slit in response to fluid pressure applied to one side thereof. The slit portion has abuttable, cooperable structures on one side, which come into forcible abutment and act to physically open the slit as the portion bulges. Preferably the abuttable structures are in the form of rings molded on the underside of the diaphragm. The slit through the diaphragm also extends through the ring, thereby forming two semi-circular ring segments. The ring segments in turn form abutment shoulders that pivot the walls of the slit away from one another when the diaphragm is bulged, thereby resulting in a more pronounced spreading force being applied to the walls, and increasing the size of the opening formed by the slit.
