ABSTRACT:
An inhalation device of cylindrical form is disclosed for the administration of medicaments in finely divided form, having a nebulization chamber for a capsule with the medicament and in which an air passageway is formed in such manner as to set the flowing air in vortical motion. The vortical motion is obtained by means of holes suitably directed or by other means such as inclined surfaces, helicoidal parts or the like. The nebulization chamber is such as to cause the capsule, under the action of the flowing air, to make movements of rotation, precession and vibration about and along its longitudinal axis within the nebulization chamber. A series of air inlet holes may be provided in the periphery of the lower portion of the nebulization chamber, the axes of which are offset from the central axis of the nebulization chamber. One or more push button-actuated needles pierce the capsule and release the powdered medicament.
