INHALER UTILIZING A VENTURI

摘要

An inhaler for the inhalation of a liquid or powder medicament includes a housing and an inhalation aid or nozzle defining a venturi passage for dispersing the medicament in air sucked through the venturi passage by the user. All of the elements of the inhaler can be incorporated in a single tube with a constriction, which may contain the medicament in a perforable capsule. Alternatively, a container mounted on the housing feeds the medicament into the venturi passage upstream of the constriction or diffuser portion of the passage, the medicament being in single dosage form.
