Abstract
In preferred aspects, the present invention comprises a self-priming needle-free "Y"-adapter for use with intravenous delivery systems. The "Y"-adapter comprises a "Y"-shaped housing having an inlet passageway, an outlet passageway, and an injection access passageway. Each of the three passageways has an interior end and an exterior end. An inlet port is located at the exterior end of the inlet passageway. An outlet port is located at the exterior end of the outlet passageway. An injection access port is located at the exterior end of the injection access passageway. A needle-free access device is also located in the injection access passageway adjacent to the injection access port. The interior ends of the passageways are in fluid communication and intersect with each other. In addition, the injection access passageway comprises a non-circular cross-section near its interior end. The non-circular cross-section of the interior end of the injection access passageway assists in priming the "Y"-adapter.
