Abstract

Un filtro para remover leucocitos de la sangre comprende un medio de filtro (20) encerrado en un alojamiento (30). El medio de filtro (20) incluye una region de filtro principal (MF) que comprende una estructura de membrana porosa que se extiende entre las primera y segunda superficies de piel. La estructura de membrana porosa es formada al intersectar celulas teniendo un rango de diametros. Las celulas adyacentes a la primera superficie de piel tiene diametros generalmente mas pequenos que los diametros de las celulas adyacentes a la segunda superficie de piel. La primera superficie de piel incluye un area abierta definida por poros, los cuales son formados por la interseccion de celulas con la primera superficie de la piel. La mayoria del area abierta es definida por poros que tienen un diametro de entre aproximadamente 12 ¦m y 28 ¦m.
