Abstract

UNA JERINGUILLA SIN AGUJA COMPRENDE UN CUERPO HORADADO, CON EL EXTREMO POSTERIOR DEL ORIFICIO CONECTADO, O PREPARADO PARA SER CONECTADO, A UNA FUENTE DE PRESION GASEOSA QUE PUEDE LIBERARSE INSTANTANEAMENTE EN EL ORIFICIO; EL EXTREMO INFERIOR TERMINA DETRAS DE UN DIAFRAGMA BIESTABLE QUE SE MUEVE ENTRE UNA POSICION RETRAIDA EN LA QUE PRESENTA HACIA EL EXTERIOR DEL CUERPO UNA CONCAVIDAD PARA CONTENER LAS PARTICULAS DEL AGENTE TERAPEUTICO, Y UNA POSICION EXPANDIDA, CONVEXA HACIA FUERA; LA DISPOSICION ES TAL AL USARSE, CUANDO SE LIBERA EL GAS A PRESION EN EL ORIFICIO, EL DIAFRAGMA SALTA DE LA POSICION RETRAIDA A LA EXPANDIDA Y LANZA LAS PARTICULAS HACIA EL EXTERIOR.
