Abstract

SE PRESENTAN UNAS MEMBRANAS QUE SON PERMEABLES A LOS ELECTROLITOS DE LA SANGRE Y ESTAN FABRICADOS DE COMPUESTOS DE POLIURETANO QUE TIENEN ENTRE EL 20 Y EL 50% DE SEGMENTOS DUROS. LAS MEMBRANAS ABSORVEN ENTRE EL 50 Y EL 120% DE SU PESO EN SECO DE AGUA Y TIENEN CONSTANTES DE DIFUSION DE ELECTROLITO POR ENCIMA DE 1 X 10 -6 CM2 /SEC. LAS MEMBRANAS ESTAN INCLUIDAS EN SENSORES DE ELECTROLITO DE SANGRE EN ESTADO SOLIDO Y SENSORES OPTICOS DE FIBRA ELECTROQUIMICOS PARA SUMINISTRAR SUPERFICIES COMPATIBLES Y ASEGURAR QUE LOS COMPONENTES DE LA SANGRE DELETEREOS AL ANALISIS DEL ELECTROLITO EN LA SANGRE, PERMANECEN SEPARADAS DE LOS ELEMENTOS SENSORES.
