Abstract: A body cavity examination device is provided for introducing fluid through a body cavity and then withdrawing the fluid for examination, while selectively determining which particulate matter from the body cavity is ultimately collected for examination. The device includes a hollow member. One end of the hollow member is a fluid conduit which is insertable into the body cavity. The container which holds the fluid that is introduced through the body cavity is in fluid communication with the member. A collection receptacle is releasably secured to the opposite end of the member and is positionable in fluid communication with the member. A filter member is positioned in the opening such that all fluid withdrawn from the body cavity passes through the filter which collects particulate matter greater than a predetermined size. The fluid is introduced into the body cavity from the container and is withdrawn from the body cavity, whereupon the fluid passes through the filter member.
