A suction canister assembly comprises an enclosed receptacle having a first opening for providing suction to the receptacle and a second opening for drawing fluids, including liquids and gases, into the receptacle during suction. A unitary shut-off valve/filter element is associated with the interior side of the first opening. This element is oriented within the receptacle so as to be contacted by liquid in the receptacle which rises therein. The element is porous and is adapted to filter particulate matter from gas passing therethrough. In addition, the valve/filter element is capable of developing sufficiently high surface tension under liquid contact to serve as a barrier against liquid passage therethrough at pressure differentials across the element when vacuum is applied on one side of the element. As a result, the element is adapted to terminate suction through the suction opening when liquid rises in the receptacle to completely cover the element.

A suction canister assembly for collecting body fluids comprising: a cup-shaped receptacle having an open mouth portion and an opposed bottom wall; a cover sealably connected to said receptacle over said mouth portion, said cover having a suction opening therethrough adapted to communicate with a source of vacuum applied to the exterior side of said suction opening, and having a liquid passage opening means therethrough adapted to communicate with a source of liquid exterior to said canister so that liquid is passable therethrough to enter said receptacle under suction conditions provided through said suction opening by said vacuum source; and a unitary shut-off valve/filter element connected to the interior side of said suction opening lying within a single suction path extending only from the interior of said receptacle to said suction opening so that all gases are exchanged between said receptacle and said suction opening through said element, said element adapted to lie substantially parallel to the free upper surface of liquid which enters said receptacle when said bottom wall rests on a substantially horizontal surface, said element oriented within said receptacle to be contacted by liquid in said receptacle which rises to a predetermined level, said element being porous with a maximum pore rating of about 0.5 micron for filtering particulate matter including microorganisms from gas passing therethrough, said element capable of developing sufficiently high surface tension under liquid contact to serve as a barrier against liquid passage therethrough at pressure differentials across said element up to 14.7 psi, said element adapted to terminate suction through said suction opening at suction pressures up to 14.7 psi when liquid rises in said receptacle to completely cover said element.
