Abstract
An inhalation device including an aerosol generator for dispensing droplets of liquid medicament comprising a housing defining a liquid receptacle having an opening, a nozzle arrangement comprising a plurality of orifices, vibrating means for vibrating the nozzle arrangement, and means for introducing the liquid medicament on the outer surface of the nozzle arrangement. Control means are also provided for controlling the vibrating means such that when the liquid medicament is introduced on the outer surface of the nozzle arrangement, the nozzle arrangement may be vibrated to cause the liquid to enter the liquid receptacle through the orifices and thereafter be expelled from the orifices through the outer surface of the nozzle arrangement in the form of atomised droplets.
