Zusammenfassung:A device (10) for filtering red blood cells includes a main body (12) having at least one inlet (14) and at least one outlet (16), a filtering region (18) extending through the main body from the inlet to the outlet, and a filter (20) including pillars (22) disposed in the filtering region and grouped into islands (24). The pillars of each island have inter-pillar spacings (A) effective to trap red blood cells. The islands have inter-island spacings (B) that are larger than the inter- pillar spacings. The islands are distributed in the filtering region to define tortuous flow paths (26) between the islands from the inlet to the outlet. Un dispositif (10) pour filtrer des globules rouges comprenant un corps principal (12) ayant au moins une entrée (14) et au moins une sortie (16), une zone de filtration (18) s'étendant à travers le corps principal de l'entrée à la sortie, et un filtre (20) comprenant des piliers (22) disposés dans la zone de filtration et groupés en îlots (24). Les piliers de chaque îlot présentent des espacements inter-piliers (A) efficaces pour piéger les globules rouges. Les îlots ont des espacements inter-îlots (B) qui sont plus grands que les espacements inter-piliers. Les îlots sont répartis dans la zone de filtration pour établir des trajets d'écoulement tortueux (26) entre les îlots de l'entrée à la sortie.
