Abstract

A water trap for a respiratory airline comprises a top and base the respective openings of which mate when they are releasably connected e.g. by a bayonet-joint. The opening of the top is partially spanned centrally by a disc, leaving an annular pathway for water around the periphery of the disc. A resilient annular sealing member connected at its outer periphery to the top makes sealing contact with the disc when the base is removed, but when the base is connected to the top the upper periphery of the base raises the sealing member to allow water to fall from the top and be collected in the base.
