Abstract
Official abstract text for this publication.
A filter element and method for retaining particles of a medium, for example rare cells of blood. The filter element includes at least one opening that has an elongate cross section and/or a cross section that decreases in a flow direction. The filter element may be bordered by a transparent wall. The filter element may be provided with a plurality of elongate openings of a stepwise decreasing cross section that are arranged on a common transparent slide. The filter element permits high flow rates to be realized throughout the filtering process and the retained particles are immediately ready for visual inspection without a need for a further transfer.
First claim
Opening claim text (preview).
The invention claimed is: 1. A filter element for retaining components of a medium flowing in a flow direction through at least one opening, wherein said opening is a bottleneck in a flow path of the medium wherein the flow path is wider in front and behind the bottleneck; has an elongate cross section, measured perpendicular to the flow direction, that decreases along an extended length of the opening in the flow direction; and is bordered by a transparent wall.…
