Abstract

SE DESCRIBE UN DISPOSITIVO (10) DE HEMO(DIA)FILTRACION CON DIALIZADOR (12) Y DOS FILTROS (38) Y (60) ESTERILES. LA PRIMERA CAMARA (42) O (64) DE AMBOS FILTROS (38) O (60) DE ESTERILIZACION SON CONECTABLES AL MENOS EN TIEMPO PARCIAL EN EL FLUJO DE PASO, DE TAL MODO QUE LAS MEMBRANAS (40) O (62) DE AMBOS FILTROS (38) O (60) DE ESTERILIZACION SON ENJUAGADOS DE FORMA LIBRE Y SE EVITA LA RECOLECCION DE GERMENES Y PIROGENOS DE FORMA FIABLE. CON ELLO SE EVITA UNA ELEVACION DE LA PRESION (TMP) DE TRANSMEMBRANA, DE MODO QUE ES IMPROBABLE LA GENERACION DE UNA RUPTURA Y CON ELLO SE GARANTIZA LA ESTERILIDAD DEL LIQUIDO DE DIALISIS Y SE MEJORA LA SEGURIDAD DEL DISPOSITIVO (10) DE HERMODIAFILTRACION.
