The disclosure is directed to a suction collection and drainage apparatus which comprises a fluid collection container and a separate tissue specimen trap container. The collection container is connected, by a tube, to a source of suction. Another tube serves to connect the collection container and the trap container together to provide fluid communication therebetween. Still another tube serves to connect the trap container to an endoscope to permit collection of tissue specimens aspirated from the patient and transmitted to the trap container. A filter is supported within the trap container and is formed having a plurality of traps and a plurality of enlarged openings spaced around the filter. The filter is movable relative to the inlet of the tube between a first position wherein a selected one of the traps is positioned to receive and collect the tissue specimen and a second position wherein a selected one of the openings is positioned to permit passage therethrough of body fluids when suction is applied to the apparatus.
