Abstract

PROCEDIMIENTO DE PREPARACION DE FIBRAS HUECAS SEMIPERMEABLES DE CELULOSA, UTILIZADAS EN CELULAS UTILES PARA LA DESINTOXICACION DE SANGRE POR HEMODIALISIS O HEMOFILTRACION. SE PREPARAN FIBRAS HUECAS HILANDO EN FUNDIDO UNA COMPOSICION DE HILADURA EN FUNDIDO DE ESTER DE CELULOSA QUE CONSISTE EN 35 A 80 POR CIENTO EN PESO DE UN ESTER DE CELULOSA, Y UN POLIOL QUE TIENE UN PESO MOLECULAR PROMEDIO DEL ORDEN DE 106 A 900. UNA MADEJA DE DICHAS FIBRAS HUECAS SE DISPONEN PARA QUE TERMINEN EN UNA LAMINA TUBULAR, ESTANDO UNA SERIE DE DICHAS LAMINAS TUBULARES SITUADAS EN FORMA SELLADA ENTRE UNA CAMARA DE DIALIZADO Y UNA CAMARA DE SANGRE, ASEGURANDOSE A LAS MISMAS PARA SEPARAR CON ELLO DICHAS CAMARAS EN UNA RELACION ESTANCA A LOS FLUIDOS, PROPORCIONANDO LOS CONDUCTOS EN DICHAS FIBRAS COMUNICACIONES ENTRE LOS INTERIORES DE DICHAS CAMARAS DE SANGRE.
