Device for administering a medicinal aerosol

摘要

The suspension of the aerosol is carried out in the complementary zone which is profiled and arranged on a vertical plane to limit the aerosol losses by deposit due to action of gravity on the aerosol particles. The storage zone (ZS) of a minimal height of 6 cm allows a dispersion of aerosol suspension in total volume without recycling the aerosol deposited on walls. The complementary zone has openings for allowing the circulation of gas or the aerosol. The transfer zone has a cylinder open at each end and a circular cross section of a L- and T-shaped part which is open at each end. The complementary zone has a cylindrical collar which has upper part (1a) narrowed to conical configuration and lower part (1b) to support the aerosol transfer.
