A dispensing device is described with a mixing chamber in which a dose of powder or other medicament is introduced through an outlet for a human body cavity, such as a mouthpiece or a hollow projection suitable for inserting in a nostril. A source of gas under pressure, for example from an aerosol can, is introduced into the chamber at an angle, and there is present in the chamber a larger movable element, such as a steel ball, which vibrates and breaks up the particles or aggregates. In one modification a half capsule containing the dosage may be introduced into the chamber and the capsule after emptying itself constitutes the moving element. |
