Abstract

En fremgangsmåte og anordning for å rense konvensjonelt behandlet blodplasma, for å fjerne i hovedsak alle resterende leukocytter og samtidig opp- rettholde nyttig strømningsmengde for medisinsk nyttige mengder av plasma, benytter et engangsbruk, varme-sterili- serbart filter (l) som benytter ett eller flere dybde-type forfiltre (29) og minst en mellomliggende hydrofil mikro- porøs membran (25a) fulgt av minst en endelig hydrofil mikroporøs membran (25b) som har mindre porestørrelse enn den mellomliggende membran, inne i et felles hus.
