Abstract
METODO Y MAQUINA MEDICA PARA CALIBRAR UNA BOMBA PERISTALTICA (36, 39) PARA SU UTILIZACION EN CONEXION CON UNA MAQUINA MEDICA, COMO POR EJEMPLO UNA MAQUINA PARA LA DIALISIS. LA MAQUINA COMPRENDE UN MEDIDOR DEL FLUJO DE FLUIDO INTERNO (18, 19). EL FLUIDO SE INTRODUCE DENTRO DEL SEGMENTO DE LA BOMBA (36) Y ES BOMBEADO MEDIANTE LA BOMBA PERISTALTICA CON UN INDICE DE ROTACION SUBSTANCIALMENTE CONSTANTE. SE OBTIENEN TRES PRESIONES DIFERENTES DE ENTRADA Y SE MIDEN MEDIANTE UN MANOMETRO (16) Y EL FLUJO DE FLUIDO CORRESPONDIENTE SE MIDE MEDIANTE UN MEDIDOR DEL MOVIMIENTO DE FLUIDOS INTERNO (18, 19) PARA LA OBTENCION DE UNA PAREJA DE VALORES DE CALIBRACION. LA CURVA DE GRADUACION SE CALCULA A PARTIR DE DICHA PAREJA DE VALORES MEDIANTE UN ORDENADOR (23) SITUADO EN EL INTERIOR DE LA MAQUINA MEDICA. EL INDICE DEL MOVIMIENTO DE FLUIDOS SE DETERMINA POR EL CITADO ORDENADOR (23) A PARTIR DE DICHA CURVA DE CALIBRADO, BASANDOSE EN LA PRESION DE ENTRADA ACTUAL Y EN EL INDICE DE REVOLUCIONES ACTUALES DE LOS MEDIOS PROPULSORES.
