ABSTRACT:
Micronized spray device for washing nasal and neighboring cavities including a bell-shaped body which forms an atomization chamber on the bottom whereof there is a region for containing a washing liquid in which a spray nozzle draws; the spray nozzle is associated with a compressed-air injector and is axially aligned with the inner outlet formed by the bell-shaped body. An outer skirt furthermore surrounds the bell-shaped body and forms an outer outlet which is located at the inner outlet and forms a chamber for collecting the catarrhal material that has been detached from the nasal cavities; the chamber is connected to the outside to vent the pressure generated during expiration. The outer skirt can be arranged in a first position, in which the outer outlet is spaced from the inner outlet so as to form an interspace that is connected to the collection chamber, and in a second position, in which the outer outlet overlaps the inner outlet.
