Abstract: Certain embodiments of the present invention include a male luer connector having a valve arrangement for keeping a passage that extends through the male luer connector closed when the male luer connector is not attached to a corresponding female luer connector. This passage of the male luer connector may be opened by connecting the male luer connector to a female luer connector. The valve arrangement of the male luer connector may include a movable sealing element arranged around a central fluid conduit. In some embodiments, the male luer connector may include a filter that is permeable to gas, but substantially impermeable to liquid, thus allowing gas to be purged from the male luer connector while substantially preventing liquid from leaking from the connector at least when the male luer connector is not connected to a female luer connector.

Abstract: A liquid mixing infusor includes a main body defining an internal chamber and has an upstream port, a downstream port and a confluent port. Each port is fluidly couplable with the internal chamber. A valve may be mounted within the internal chamber of the main body and is adapted for rotational movement between a blocking position interrupting fluid flow between the confluent port and one of the upstream port and the downstream port and between the upstream port and the downstream port, and a flow position permitting fluid flow between the upstream port and the downstream port. A manually manipulative member is mounted relative to the main body and operatively connected to the valve. The manipulative member is movable to cause corresponding movement of the valve between the blocking position and the flow position.
