Abstract
Le problème posé par l'invention est l'obtention d'un épurateur de sang de type à fibres creuses ayant un polymère hydrophobe et un polymère hydrophile, présentant une quantité réduite de matière éluée d'une membrane, une excellente sécurité, une instabilité réduite de fonctionnement due au contact avec le sang et une excellente compatibilité avec le sang. Pour résoudre les problèmes posés ci-dessus, l'invention présente une membrane à fibres creuses présentant une grande uniformité de structure de membrane ainsi que des trous dans une surface intérieure, un bon équilibre de propriétés hydrophile et hydrophobe, une faible quantité de matière éluée de la membrane et une excellente compatibilité avec le sang, dans le cas où la composition polymère optimale est sélectionnée pour un fluide de filage contenant un polymère hydrophobe et un polymère hydrophile dissous dans celui-ci, la relation établissant que la vitesse linéaire de décharge de l'agent de formation de creux > la vitesse linéaire de décharge d'un fluide de filage est satisfaite lorsque le fluide de filage est déchargé par un ajutage avec l'agent de formation de creux et introduit dans un bain de coagulation par une partie d'espace, et une membrane à fibres creuses est coagulée tout en étant étirée dans le bain de coagulation.
