Abstract
A connector for medical fluid vessels includes a fluid-seal fitting such as a male plug defining a lumen and mating with a cooperating connector, a mechanical fastener such as a screw thread for mating with the cooperating connector, and an outer housing positioned around the plug to form an annular space. Optionally, a cap can be provided with a fluid-seal fitting such as a male plug for mating with the lumen of the connector. The connector includes one or more vent openings for drainage and air-drying of any residual fluid in the annular space when capped, as well as for breaking a vacuum to prevent fluid backflow and thus ensure more accurate dosing. In some embodiments, the vent openings are provided in the outer housing. And in some embodiments, the vent openings are provided in the cap.
