Abstract

FIL CREUX SERVANT DE MEMBRANE POUR DIALYSE A SURFACES D'ECHANGE AMELIOREES. LA PRESENTE INVENTION DECRIT UNE MEMBRANE POUR DIALYSE EN CELLULOSE REGENEREE A PARTIR DE SOLUTIONS CUPRAMMONIUM, EN FORME D'UN FIL CREUX AYANT UN ESPACE VIDE CONTINU 2 ET UNE SURFACE LATERALE FERMEE 1, QUI EST CARACTERISEE PAR LE FAIT QUE, DANS UNE SECTION TRANSVERSALE PERPENDICULAIRE A L'AXE DU FIL, LA DIFFERENCE DES DISTANCES DE LA SURFACE LATERALE ET DE LA DELIMITATION DE LA LUMIERE VARIE A CHAQUE FOIS, A PARTIR DU CENTRE DU FIL SUR LE POURTOUR DE LA SURFACE LATERALE. LE PROCEDE DE FABRICATION EST AUSSI DECRIT. UTILISATION DES FILS CREUX OBTENUS COMME MEMBRANES POUR HEMODIALYSE.
