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.

Abstract: A tool for use on safety showers may include a funnel, a drain system, a base, and a height adjustment mechanism. The funnel has an interior with a width wider than a showerhead of the safety shower, so that a showerhead may fit within or seal against the interior of the funnel. The drain system connected to conduct a flow from the funnel. The base supports the drain system and the funnel and may be placed on a floor beneath the showerhead, and the height adjustment mechanism may be coupled to control a height of the funnel and control sealing pressure that the funnel applies to a showerhead.
