Abstract
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 A filter member is positioned in the opening such that all fluid withdrawn from the body cavity passes through the filter which collects particulate matter greater than a predetermined size. The fluid is introduced into the body cavity from the container and is withdrawn from the body cavity, whereupon the fluid passes through the filter member.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
283 words
A body cavity examination device for alternately introducing fluid into a body cavity and then withdrawing the fluid and pieces of particulate matter suspended therein for examination, comprising: a hollow member having a single opening extending therethrough, one end of said member comprising an open end portion adapted for positioning within the body cavity; pump means in fluid communication with said hollow member for introducing said fluid into said body cavity through said hollow member and for withdrawing said fluid, with said pieces of particulate matter from the body cavity suspended therein, from said body cavity into said hollow member, said pump means having a first end secured to the opposite end of said hollow member; a receptacle in fluid communication with said pump means; means for sealingly engaging said receptacle to said pump means and providing selective removability of said receptacle from the remainder of said body cavity examination device; and filter means positioned between said open end portion and said receptacle such that all fluid received in said receptacle passes through said filter means, said filter means providing fluid communication between said hollow member and said receptacle, whereby said fluid is introduced into said body cavity by said pump means and is withdrawn from said body cavity at least in part by said pump means, and said fluid when withdrawn from said body cavity passes through said hollow member and then through said filter means into said receptacle, and said filter means selectively determines the size of the particulate matter that is received in the receptacle by collecting the larger pieces of particulate matter suspended in said fluid while permitting smaller pieces of particulate matter suspended therein to enter said receptacle.
Claim 2
Dependent Claim
283 words
