从血液或其他介质中过滤颗粒
摘要：
公开了一种过滤器元件(200)和方法，以用于保留介质的颗粒，例如保留血液的(稀少)细胞。所述过滤器元件(200)包括至少一个开口(220)，所述开口(220)(i)具有细长横截面，和/或(ii)具有沿流动方向(x)减小的横截面，和/或(iii)以透明壁为边界。优选地，所述过滤器元件(100、200、300)被提供有横截面逐步减小的多个细长开口(220)，所述多个细长开口被布置在公共透明载片上。因此能够在整个过滤过程中实现高流率，并且所保留的颗粒立即准备好用于视觉检查，而无需进一步转移。
摘要（英）：

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.
