Abstract

SE DESCRIBE UNA MEMBRANA DE FIBRA HUECA DE CELULOSA REGENERADA, QUE TIENE UNA PARTE HUECA QUE PENETRA CONYINUAMENTE EN LA DIRECCION DE LOS EJES DE LAS FIBRAS, UNA POROSIDAD EN HUMEDO DE 60-95 %, Y UN COEFICIENTE DE TAMIZADO DE ALBUMINA NO MAYOR QUE 0,15 EN HEMOFILTRACION. LA MEMBRANA DE FIBRA HUECA TIENE PREFERIBLEMENTE UN RADIO DE PORO MEDIO EN ESTADO HUMEDO DE 40-250 A (GRADOS) , Y EL COEFICIENTE DE TRANSFERENCIA DE MASA PARA (BETA)2-MICROGLOBULINA DE 2X10-5 CM/SEG POR LO MENOS. LA MEMBRANA DE FIBRA HUECA PREFERIBLEMENTE CONTIENE POLIETILENGLICOL Y TIENE EL COEFICIENTE DE TAMIZADO DE ALBUMINA NO MAYOR QUE 0,1. LA MEMBRANA DE FIBRA HUECA ES ESECIALMENTE UTIL PARA TERAPIA POR HEMOFILTRACION, TAL COMO HEMODIALISIS.
