Abstract

UN ACUMULADOR (30) PARA UN SISTEMA DE INFUSION IMPLANTABLE EMPLEA UN PAR DE DIAFRAGMAS (47, 52) MOVILES AL UNISONO POR UN FLUIDO DE TRANSFERENCIA DISPUESTO ENTRE ELLOS. UNA CAMARA (41) DE INFUSION RECIBE INFUSION EN CANTIDADES MEDIDAS A TRAVES DE LA ENTRADA (42) Y DISPENSA LOS CONTENIDOS COMO UNA FUNCION DE UNA OPERACION DE VALVULA OSCILANTE. DURANTE EL LLENADO, EL PRIMER DIAFRAGMA (47) SE DESVIA HACIA ARRIBA Y POR TRANSFERENCIA DE PRESION OCASIONA UNA DESVIACION CORRESPONDIENTE AL SEGUNDO DIAFRAGMA (52). EL SEGUNDO DIAFRAGMA (52) ES DESVIADO POR RESORTES, GAS BAJO PRESION O SIMILARES. POR ESTO, CUANDO LA VALVULA (26) DE ENTRADA SE CIERRA Y LA VALVULA (28) DE SALIDA SE ABRE, LA PRESION DIFERENCIAL A TRAVES DEL SEGUNDO DIAFRAGMA (52) OCASIONA DESVIACION HACIA ABAJO Y FLUIDO FLUYE A TRAVES DE LA SALIDA (44). TOPES NO MECANICOS SON NECESARIOS EN LA CAMARA (41) PARA EL PRIMER DIAFRAGMA (47) YA QUE SU MOVIMIENTO ES CONTROLADO POR LA PRESION DIFERENCIAL A TRAVES DEL SEGUNDO DIAFRAGMA (52).
