Abstract

UN PULVERIZADOR NASAL TIPO JERINGA QUE INCLUYE UN MIEMBRO CILINDRICO ALARGADO QUE TIENE UN EXTREMO PROXIMO ABIERTO, UNA CAMARA PARA RETENER UN FLUIDO Y UNA PORCION DE PUNTA QUE SE EXTIENDE DESDE EL EXTREMO DISTAL DEL MIEMBRO CILINDRICO CON UN PASO A SU TRAVES QUE SE COMUNICA CON LA CAMARA. HAY COLOCADO UN OBTURADOR DE MANERA DESLIZABLE ENGANCHADO DE MANERA HERMETICA DENTRO DEL ELEMENTO CILINDRICO. UNA VARILLA PULSADORA ALARGADA SE PROYECTA CERCA DEL OBTURADOR Y SE EXTIENDE HACIA AFUERA DEL EXTREMO PROXIMO ABIERTO DEL MIEMBRO CILINDRICO. UNA TOBERA DE PULVERIZACION SE EXTIENDE HACIA AFUERA DESDE LA SECCION DE LA PUNTA E INCLUYE UN CONDUCTO A SU TRAVES EN COMUNICACION HIDRAULICA CON EL PASO. UN EXTREMO DISTAL DE LA TOBERA INCLUYE UNA ABERTURA DE PULVERIZACION EN COMUNICACION HIDRAULICA CON EL CONDUCTO. LA TOBERA INCLUYE TAMBIEN UNA VALVULA INTERNA PARA PERMITIR QUE EL LIQUIDO A PRESION QUE HAY EN LA CAMARA FLUYA DISTALMENTE A TRAVES DEL CONDUCTO Y A TRAVES DE LA ABERTURA AL TIEMPO QUE EVITA QUE EL LIQUIDO QUE NO SE ENCUENTRA A PRESION DENTRO DE LA CAMARA FLUYA A TRAVES DE LA ABERTURA.
