Abstract

Se proporciona un cartucho de filtrado de doble etapa (10). El cartucho (10) puede embeberse como un cartucho de hemodialfiltracion de dilucion media o como un cartucho de filtrado de esterilizacion redundante. El cartucho (10) incluye un alojamiento (12) que tiene un primer extremo y un segundo extremo opuesto. El alojamiento (12) posee una entrada (20) y una salida (60) de fluido primarias en el primer extremo del cartucho (10). El alojamiento (12) tambien define la primera y segunda etapas de filtrado (14, 16) con la primera etapa de filtrado (14) que incluye los primeros elementos de filtrado (40) colocados entre el primer y segundo extremos del alojamiento (12). La segunda etapa de filtrado (14) incluye los segundos elementos de filtrado (42) colocados entre el primer y segundo extremos del alojamiento (12) con la salida de fluido (64) que se comunica con los segundos elementos de filtrado en el primer extremo.
