Abstract

SE DESCRIBE UN APARATO DE CONTROL DE LA CIRCULACION DE FLUIDOS PARA SER UTILIZADO EN LA SEPARACION Y FILTRACION QUE TIENE UN ELEMENTO DE QUITA Y PON ESTERILIZABLE/DESECHABLE (27) QUE SE PUEDE ENGANCHAR A UNA PARTE FIJA (26). CUANDO ESTA ENGANCHADO LA CIRCULACION DE FLUIDO ALREDEDOR DE UN CIRCUITO HIDRAULICO ES CONTROLADA PARA OPTIMIZAR LA SEPARACION. SE PUEDE COMBINAR EL ELEMENTO EXTRAIBLE (27) CON UNA UNIDAD FILTRANTE (16) PARA FORMAR UNA CAJITA DESECHABLE UNITARIA (90). SE PUEDEN INCORPORAR SENSORES (38, 40; 165, 167) ES EL APARATO PARA MEDIR LOS PARAMETROS DEL FLUIDO TALES COMO LA PRESION, VISCOSIDAD Y PH. SE UTILIZAN SENSORES DE PRESION (165, 167; 226, 228) COBRADOS EN LA ENTRADA Y SALIDA DEL FILTRO PARA CONTROLAR LA PRESION A TRAVES DE LAS MEMBRANAS (TMP) PARA OPTIMIZAR LA FILTRACION O SEPARACION Y EN UNA APLICACION ESTO SE UTILIZA PARA CONTROLAR LA SEPARACION DE PLASMA DONADOR.
