Abstract

MEMBRANA DE FIBRA OCA SEMI-PERMEáVEL, UMECTáVEL COM áGUA, HIDROFìLICA, PARA PURIFICAçãO DE SANGUE, E, MéTODO PARA PRODUZIR UMA MEMBRANA DE FIBRA OCA SEMI-PERMáVEL, UMECTáVEL COM áGUA, HIDROFìLICA Membrana de fibra oca semi-permeável hidrofilica para tratar sangue, possuindo uma estrutura integralmente assimétrica baseada em um polímero sintético. A membrana de fibra oca compreende uma camada de separação sobra a superfície interna da mesma e uma camada de suporte de poro aberto que é adjacente à mesma, em adição a uma taxa de ultrafiltração de 5-25 ml/(h.m¬2¬.mmHg). A membrana de fibra oca está destituída de substâncias adicionais estabilizadoras de poro e possui um coeficiente de peneiração para albumina de um máximo de 0,005, e um coeficiente de peneiração para citocromo c, no qual a razão é SK~ cc~ <242> 5.10¬ -5¬ UFR~ Aib~¬ 3¬ - 0,004 UFR~ Alb¬ 2¬ + 1,081 UFR~Aib - 0,25. A invenção também se refere a um método para a produção de citado tipo de membranas de acordo com um processo de coagulação não induzido por solubilidade, no qual uma solução de fiação é extrusada de um primeiro polímero sintético, opcionalmente, um segundo polímero hidrofilico por meio do vão anular de um bocal de fibra oca com o propósito de formar uma fibra oca e ao mesmo tempo, um meio de coagulação como um enchimento interior através de uma abertura central do bocal de fibra oca, o citado meio disparando a coagulação dentro da fibra oca. Uma camada de separação está incorporada sobre o lado interno da fibra oca e a estrutura da membrana. O método é caracterizado pelo fato de que o enchimento interior contém um polieletrólito possuindo cargas negativas.
