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.A method and apparatus for purifying conventionally treated blood plasma, to remove substantially all remaining leukocytes and at the same time maintain useful flow rate for medically useful amounts of plasma, utilize a disposable, heat-sterilizable filter (1) using one or more several depth-type prefilters (29) and at least one intermediate hydrophilic microporous membrane (25a) followed by at least one final hydrophilic microporous membrane (25b) having less pore size than the intermediate membrane, within a common housing.
