Abstract

BOMBA IMPLANTABLE DE PRESION CONSTANTE Y FLUJO VARIABLE, QUE EMPLEA UNA AGUJA DE RESTRICCION IN-LINE (12) CON UNA DISTANCIA DE INSERCION VARIABLE CON UNA CAPILARIDAD (10). EL GRADO DE INSERCION DETERMINA LA RESTRICCION EFECTIVA EN LA CAPILARIDAD. LA AGUJA DEBE REPONERSE DESPUES DE LA IMPLANTACION PARA VARIAR LA TAS DE DISTRIBUCION DE LA DROGA, CAMBIANDO LA RESTRICCION EFECTIVA EN LA CAPILARIDAD. SE PUEDEN USAR VARIOS ACOPLADORES DE MANERA QUE UNA LUMBRERA AUXILIAR (92) DISTRIBUYA EL ELEMENTO DIRECTAMENTE EN EL INTERIOR DEL CATETER DE SALIDA (24), ASI EL MEDICAMENTO DE LA CAMARA PRINCIPAL (22) NO PASA A TRAVES DE LA CAMARA AUXILIAR. UNA COMBINACION DE CATETERES DE DOBLE LUZ (106) Y DE CONECTORES EN T (100) SE UTILIZAN PAR PROPORCIONAR CAMPOS DE INFUSION PARALELA.
