Abstract

ESTETOSCOPIO QUE CONSTA DE UN CUERPO (10), UN VASTAGO TUBULAR (20) Y UN RETEN DE POSICIONAMIENTO (30). EL CUERPO TIENE VARIOS MICROFONOS (11,12), CADA UNO DE LOS CUALES TIENE UNA ABERTURA (14,15) EN SU APICE Y UN ENTRANTE CENTRAL (13). EL VASTAGO TUBULAR VA FIJADO DE FORMA GIRATORIA (18,19,21) DENTRO DEL ENTRANTE CENTRAL Y TIENE UNA ABERTURA (23) EN SU PARED QUE SE ALINEA DE FORMA SELECTIVA CON UNA DE LAS ABERTURAS DE LOS MICROFONOS. EL RETEN TRANSMISOR DE SONIDO VA MONTADO TRANSVERSALMENTE DENTRO DEL VASTAGO Y ALINEADO CON LA ABERTURA EN LA PARED DE ESTE. EL RETEN DE POSICIONAMIENTO (30) TIENE UN ELEMENTO CILINDRICO HUECO (31) Y UN RESORTE (32). EL ELEMENTO CILINDRICO HUECO TIENE UNA PARTE INFERIOR ABIERTA (33) Y UN ASIENTO EXTREMO (35) CON UNA ABERTURA (34). EL EXTREMO DE ASIENTO ESTA BISELADO Y SE PROLONGA MAS ALLA DE LA ABERTURA EN LA PARED DEL VASTAGO PARA ACOPLARSE AL CUERPO. CUANDO EL ASIENTO ESTA ALINEADO CON UNA ABERTURA SELECCIONADA DE LOS MICROFONOS, SE ASIENTA PARA MANTENERLA ABERTURA DEL MICROFONO EN ALINEACION CON LA ABERTURA EN EL EXTREMO DE ASIENTO Y CREAR UN CONDUCTO PARA EL SONIDO EN EL VASTAGO TUBULAR.
