The outer housing includes an opening adapted to receive the anatomy of the nasal region. The outer housing also contains a reservoir for holding a supply of medicinal liquid. The inner housing contains and protects an oscillator which energizes an electromechanical transducer, the transducer extending through a wall of the protective housing in sealed relation thereto and carrying a vibratory atomizing member which is positioned to receive liquid from the reservoir. The oscillator includes a position sensitive on-off switch which permits operation only when the inhalator is in a predetermined orientation. A droplet shield is positioned forward of the atomizing member, between the atomizing member and the opening in the outer housing so that liquid droplets of the aerosol and respiration moisture precipitate thereon and run off along a path over which the droplets will not strike the atomizing member. | |
