Abstract

Membrane de dialyse en cellulose régénérée à partir de solution cellulose-oxyde de cuivre ammoniacal pour l'hémodialyse. La membrane est formée à partir de plusieurs couches liées solidement les unes aux autres et éventuellement la couche disposée du côté sang est constituée totalement ou partiellement d'une cellulose modifiée.
