Patent ID: 7758816

Claim:
A sample chamber for use in a cytocentrifuge device for receiving and distributing a sample containing sediment material to be deposited onto a microscope slide during cytocentrifugation, comprising: a sample receiving well for receiving and holding the sample prior to centrifugation; a sedimentation chamber comprising an outer open sedimentation end, an inner end, and a floor, the open sedimentation end adapted to be positioned adjacent a microscope slide allowing the sample to collect in the sedimentation chamber toward the open sedimentation end allowing sediment material from a sample in the sedimentation chamber to contact the microscope slide during centrifugation and forming a vacant space at the inner end of the sedimentation chamber during centrifugation; a passage from the sample receiving well into the sedimentation chamber whereby sample will flow under centrifugal force from the sample receiving well into the sedimentation chamber during centrifugation; a liquid removal chamber in communication with the vacant space in the sedimentation chamber during centrifugation to remove sample liquid from the sedimentation chamber when centrifugation stops and sample liquid flows into the vacant space; a communication passage between the liquid removal chamber and the sedimentation chamber, opening into the sedimentation chamber adjacent the inner end and floor of the sedimentation chamber; and a sealing material surrounding the open end of the sedimentation chamber for sealing against the microscope slide when the sample chamber is positioned in a cytocentrifuge device against a microscope slide.
