Abstract

ESTA INVENCION SE REFIERE A UN APARATO PARA TRATAR FLUIDOS EN UN CIRCUITO COMPRENDIENDO UNA FUENTE DE FLUIDO (1) A SER TRATADO Y UN RECEPTOR PARA EL FLUIDO TRATADO (2), UN CIRCUITO DE FLUIDO COMPRENDIENDO AL MENOS UNA PRIMERA LINEA DE FLUIDO CONDESCENDIENTE (3) YENDO DESDE DICHA FUENTE A LA ENTRADA DE UN DISPOSITIVO DE MEMBRANA (4), UNA BOMBA (5) INTERCONECTADA EN DICHA PRIMERA LINEA DE FLUIDO ESTANDO EN FUNCIONAMIENTO PARA SUMINISTRAR UN FLUIDO SUBSTANCIALMENTE CONTINUO A DICHO DISPOSITIVO DE MEMBRANA, UNA SEGUNDA LINEA DE FLUIDO CONDESCENDIENTE (6) YENDO DESDE LA SALIDA DE DICHA MEMBRANA AL RECEPTOR Y POR LO MENOS UN DISPOSITIVO CON FUNCIONAMIENTO PARA CREAR UN FLUJO POSITIVO EN EL CIRCUITO DE FLUIDO. PARA INCREMENTAR LA ACTUACION DEL APARATO, EL DISPOSITIVO PARA CREAR UN FLUJO PULSATIL ES UNA BOMBA DE UN SOLO RODILLO (7) QUE FUNCIONA PARA CAUSAR UNA PRESION POSITIVA TEMPORAL GRADUAL ENTRE LA SALIDA Y LA ENTRADA DE LA MEMBRANA.
