-14- ABSTRACT OF THE DISCLOSURE An injection site for the infusion of a medicament into a flow path for a parenteral fluid and, more particularly, an injection site which is essentially self- priming and air-occluding and which is of extremely simple construction and easily assembled. 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. This, in effect, will largely eliminate the formation of any potential spaces in which air may be entrapped at the injection site while, concurrently, the generally spherical configuration of the puncturable member, particularly the curvilinear surface which is contiguous with the flow path for the parenteral fluid, will cause any minute quantities of introduced air, if at all present, to be conducted out of the inlet for the parenteral fluid so as to essentially render the device self-priming.
