Abstract

A therapeutic aerosol device in which an aerosol generated by a nebulising device is supplied through a nosepiece to a patient's nostril so that the main aerosol flow supplied is able to emerge from the other nostril. The main aerosol flow is superimposed by pressure fluctuations. In order to guarantee that, due to the pressure fluctuation, aerosol is transported to the paranasal sinuses, a low resistance device is provided in the other nostril.
