Abstract

DISPOSITIVO SEPARADOR PARA APLICACIONES BIOMEDICAS. CONSTA DE UNA CAVIDAD EN LA QUE SE DISPONE UNA PLURALIDAD DE CONJUNTOS DE MEMBRANAS SEPARADORAS, DE TAL MANERA QUE DIVIDAN LA CAVIDAD EN DOS GRUPOS DE VOLUMENES. CADA GRUPO DE VOLUMENES TIENE UN CONDUCTO DE ENTRADA Y OTRO DE SALIDA Y SE PUEDE ESTABLECER EN EL UN FLUJO DE UNA SUSTANCIA LIQUIDA. AMBOS FLUIDOS SE ENCUENTRAN SEPARADOS POR LOS CONJUNTOS DE MEMBRANAS INDICADOS. EL CIERRE DE LOS CONJUNTOS DE MEMBRANAS SE ESTABLECE GRACIAS A UNA COMPOSICION DE POLIURETANO NO TOXICA, OBTENIDA POR REACCION DE UN PRIMER COMPONENTE, QUE COMPRENDE UN PREPOLIMERO TERMINADO EN EL RADICAL DE FORMULA (I), CON UN SEGUNDO COMPONENTE, QUE COMPRENDE AL MENOS UN POLIOL. DICHA REACCION TIENE LUGAR EN PRESENCIA DE UNA CANTIDAD CATALITICAMENTE EFECTIVA DE ACIDO RECINOLEICO. DE EMPLEO EN EQUIPOS DE HEMEDIALISIS, HEMOULTRAFILTRACION Y OXIGENACION SANGUINEA. O
