Abstract

SE DESCRIBE UN PROCEDIMIENTO Y UN DISPOSITIVO PARA ELIMINACION DE COMPONENTES DE PLASMA DE LA SANGRE. LA SANGRE SE ADELGAZA CON UN MEDIO ADELGAZANTE, ANTES DE LA SEPARACION DEL PLASMA. LA SANGRE ASI ADELGAZADA SE SEPARA DE SUS COMPONENTES DE PLASMA EN UN FILTRO DE SEPARACION (F1). LOS COMPONENTES DE PLASMA SE PROCESAN SEGUIDAMENTE Y VUELVEN A LIMPIARSE POR SEPARACION DE LA SOLUCION ADELGAZANTE, CON LOS COMPONENTES DE SANGRE CORPUSCULARES.
