Abstract

SE DESCRIBE UNA BOMBA DE ACUMULADOR DE VALVULA IMPLANTABLE PARA EL SUMINISTRO DE MEDICACION. LA BOMBA IMPLANTABLE COMPRENDE UN DEPOSITO DE MEDICAMENTOS (18) MANTENIDO A VAPOR A PRESION CONSTANTE. EL CONJUNTO MEDIDOR DE LA MEDICACION COMPRENDE UN ACUMULADOR DE VOLUMEN FIJO (30) SITUADO ENTRE UN PAR DE VALVULAS (26, 28). LAS VALVULAS (26, 28) SE ABREN Y SE CIERRAN, ALTERNATIVAMENTE, PARA DEJAR PASAR LA MEDICACION DESDE EL DEPOSITO (18) AL ACUMULADOR (30) Y PARA DISPENSAR UNA CANTIDAD PEQUEÑA DE VOLUMEN EXACTO A UN CATETER DE SALIDA (36). PARA MINIMIZAR EL VOLUMEN MUERTO Y ASEGURAR LA DESCARGA COMPLETA, EL ACUMULADOR (30) EMPLEA UN DIAFRAGMA DE TITANIO (90) ASENTADO EN UNA POSICION MEDIANTE UN TOPE AHUECADO (92) Y, EN LA POSICION DE DESCARGA, MEDIANTE UNA PLACA SEPARADORA (98) QUE TIENE UN PATRON DE RANURA CONCENTRICO (106). LAS RANURAS (106) ESTAN EN COMUNICACION FLUIDICA CON LA ENTRADA Y LA SALIDA (58, 59). ADEMAS, UNA RANURA ANCHA (105) QUE SE EXTIENDE ENTRE LA ENTRADA Y LA SALIDA (58, 59)PROPORCIONA UNA COMUNICACION FLUIDICA ENTRE LAS RANURAS (106). LA UNIDAD SE PROGRAMA EXTERNAMENTE.
