<p>Micronized spray device (1) for washing nasal and neighboring cavities including a bell-shaped body (2) which forms an atomization chamber (4) on the bottom whereof there is a region (5) for containing a washing liquid in which a spray nozzle (6) draws; the spray nozzle is associated with a compressed-air injector (9) and is axially aligned with the inner outlet (10) formed by the bell-shaped body. An outer skirt (11) furthermore surrounds the bell-shaped body and forms an outer outlet (15) which is located at the inner outlet and forms a chamber (26) 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 (40) that is connected to the collection chamber, and in a second position, in which the outer outlet overlaps the inner outlet. <IMAGE></p> |
