Abstract

LOS PULVERIZADORES DE ULTRASONIDOS CONOCIDOS ACTUALMENTE, EN PARTICULAR PARA APLICACIONES MEDICINALES, MUESTRAN HABITUALMENTE UN PLATO PULVERIZADOR SIMILAR A ESPEJO HUECO QUE SE IMPULSA CON EL LIQUIDO A SER PULVERIZADO. ESTO HA MOSTRADO QUE, COMO CONSECUENCIA DE LA ALTURA DEL LIQUIDO RELATIVAMENTE GRANDE EN EL PLANO PULVERIZADOR, APARECEN PERDIDAS DE ENERGIA CONSIDERABLES A TRAVES DE LA REFLEXION DE LAS ONDAS DE ULTRASONIDO EN LA CAPA DE LIMITACION LIQUIDO/AIRE. ESTA SITUACION ES DESVENTAJOSA PARA UNA PULVERIZACION RAPIDA, EN PARTICULAR EN LA FORMACION DE UN AEROSOL CON ACCESO A LOS PULMONES. PARA LA ELIMINACION DE ESTA DESVENTAJA LA INVENCION HA PREVISTO UN PULVERIZADOR (2) DE ULTRASONIDOS, QUE MUESTRA UNA PIEZOCERAMICA (4) ELECTRICA Y UN CUERPO (6) DE ACOPLAMIENTO QUE SE ENCUENTRA CON LA UNION EFECTIVA CON LA PIEZOCERAMICA (4). LA SUPERFICIE DEL CUERPO (6) DE ACOPLAMIENTO QUE LLEGA A ESTAR EN CONTACTO CON EL LIQUIDO A SER PULVERIZADO ESTA CONFIGURADA COMO ELEVACION (12) EN FORMA DE SOMBRERO. DE ESTA FORMA SE ASEGURA, QUE LA ALTURA DEL LIQUIDO A SER PULVERIZADO SOBRE EL CUERPO DE ACOPLAMIENTO DE FORMA RECTA NO ES TAN ALTA COMO LA QUE SE PRODUCE EN LA UTILIZACION DE LA SUPERFICIE DEL CUERPO DE ACOPLAMIENTO CON EL LIQUIDO A SER PULVERIZADO CORRESPONDIENTE. LA INVENCION ES UTILIZABLE PRINCIPALMENTE EN TODAS LAS DISPOSICIONES DE PULVERIZADOR DE ULTRASONIDOS, EN PARTICULAR PARA APLICACION MEDICINAL, COMO POR EJEMPLO PARA INHALACION.
