Abstract

DISPOSITIVO DE CONTROL DE CIRCULACION DE FLUIDOS, ADECUADO PARA DOSIFICAR LA CIRCULACION DE SANGRE HUMANA.COMPRENDE TRES CONDUCTOS. EL PRIMERO (12) Y EL SEGUNDO (14) ESTAN ADAPTADOS, CADA UNO DE ELLOS, PARA COMUNICAR CON UNA FUENTE SEPARADA DE FLUIDO A PRESION (1, P2) Y SIRVEN PARA CONDUCIR FLUIDO A PRESION DESDE LA FUENTE ASOCIADA. EL TERCER CONDUCTO (16) LLEVA FLUIDO A PRESION DESDE EL PRIMERO (12) E INCLUYE UNA PORCION DE ENTRADA (18) QUE CONDUCE FLUIDO A PRESION DESDE ESTE PRIMER CONDUCTO (12) AL TERCERO (16), Y UNA PORCION DE SALIDA (20), QUECONDUCE FLUIDO A PRESION DESDE EL TERCER CONDUCTO (16). ESTE ULTIMO INCLUYE TAMBIEN UNA PARED (22) GENERALMENTE FLEXIBLE QUE FORMA UNA INTERFASE CON UNA PORCION DEL SEGUNDO CONDUCTO. ESTA PARED FLEXIBLE FUNCIONA EN RESPUESTA A LAS PRESIONES DEL FLUIDO EN EL SEGUNDO CONDUCTO PARA DOSIFICAR LA CONDUCCION DE FLUIDO A PRESION A TRAVES DE LAS PORCIONES DE ENTRADA Y SALIDA DEL TERCER CONDUCTO.
