FILTERING PARTICLES FROM BLOOD OR OTHER MEDIA

摘要

A filter element (200) and a method are disclosed for retaining particles of a medium, for example (rare) cells of blood. The filter element (200) comprises at least one opening (220) that (i) has an elongate cross section and/or (ii) has a cross section that decreases in flow direction (x) and/or (iii) is bordered by a transparent wall. Preferably, the filter element (100, 200, 300) is provided with a plurality of elongate openings (220) of stepwise decreasing cross section that are arranged on a common transparent slide. Thus high flow rates can be realized throughout the filtering process, and the retained particles are immediately ready for visual inspection without a need for a further transfer.

主权项

1. A filter element (100, 200, 300) for retaining components (B, C1, C2) of a medium flowing in a flow direction (x) through at least one opening (120, 220, 320),
wherein said opening
is a bottleneck in the flow path of the medium;has an elongate cross section, measured perpendicular to the flow direction, that decreases in flow direction (x); andis bordered by a transparent wall (101).
