Abstract

a. Fibres creuses. b. Des sites actifs sont présents 1 sur la portion superficielle extérieure ou sur la portion superficielle intérieure ou 2 à la fois sur la portion superficielle extérieure et sur la portion superficielle intérieure des fibres creuses et ayant une perméabilité à l'eau de 2 à 10 l/m2.h.mmHg et un débit de filtration de membrane pour une solution de gamma globuline de 0,5 à 10l/m2.h.mmHg. c. Rein artificiel.at. Hollow fibers. b. Active sites are present 1 on the outer surface portion or on the inner surface portion or 2 on both the outer surface portion and on the inner surface portion of the hollow fibers and having a water permeability of 2 to 10 l / m2.h.mmHg and a membrane filtration rate for a gamma globulin solution of 0.5 to 10l / m2.h.mmHg. vs. Artificial kidney.
