Abstract

La presente invención se relaciona con un dispositivo, sistema y método para intercambiar componentes entre el primer y segundo fluidos por el contacto directo en un canal microfluidico. Los fluidos fluyen como capas delgadas en el canal. Uno de los fluidos se pasa a través de un filtro una vez que sale del canal y se recircula a través de un procesador secundario que cambia las propiedades del fluido. El fluido recirculado se reusa para el intercambio adicional. El filtro excluye las células sanguíneas del fluido recirculado y previene o limita la obstrucción del filtro. El procesador secundario remueve residuos metabólicos y agua por diafiltración.
