Abstract

EL CONTENEDOR QUE GENERALMENTE TIENE UNA FORMA CILINDRICA TIENE UN FILTRO (1) COLOCADO DENTRO DE EL Y UNA SERIE DE DIVISIONES (5, 6, 7) QUE SE EXTIENDEN, CADA UNA DE ELLAS, HACIA ARRIBA DESDE EL FONDO (2) DEL CONTENEDOR PROPORCIONANDO UNA SERIE DE SECCIONES INFERIORES ADYACENTES PARA INCLUIR UNA SECCION DE ENTRADA (5, 7) DENTRO DEL CONTENEDOR. LA SECCION DE ENTRADA TIENE UN PUESTO DE ENTRADA (8) EN UN LADO DEL FILTRO QUE INTERCONECTA LA SECCION DE ENTRADA CON LA ENTRADA (4A) DEL CONTENEDOR Y CADA UNA DE LAS SECCIONES TIENE UN PUESTO DE SALIDA EN EL OTRO LADO DEL FILTRO. CUANDO SE INTRODUCE LA SANGRE EN EL FILTRO, LA SANGRE FLUYE INICIALMENTE A BAJAS VELOCIDADES DE FLUJO (A) SOLO A TRAVES DE LA SECCION DE ENTRADA Y A VELOCIDADES DE FLUJO SUFICIENTEMENTE ALTAS (B Y C) EL NIVEL DE SANGRE SOBREPASA LA ALTURA DE LA DIVISION DE LA SECCION DE ENTRADA Y SIGUE FLUYENDO SUCESIVAMENTE POR LAS DIVISIONES Y A TRAVES DE LAS SECCIONES ADYACENTES.
