Abstract
Dializador (100) con un alojamiento para filtros (110) y por lo menos un haz de fibras dispuesto en el alojamiento para filtros (110), en donde el haz de fibras comprende una pluralidad de fibras huecas (120) hechas de un material de membrana semipermeable, caracterizado porque las fibras huecas (120) comprenden exactamente un estrechamiento (122) a lo largo de su longitud total, en donde el diámetro interno de la fibra hueca se reduce con respecto a las secciones de las fibras huecas (120) que son adyacentes al estrechamiento (122), en donde los estrechamientos (122) se disponen entre los extremos de las fibras huecas (120).
