Abstract

An inhalation therapy device includes a supply element for a gaseous medium, for example ventilation air of a ventilation device, and a flow influencing element, by means of which a sheath flow is formed around an expansion area for an aerosol generated by an aerosol generator for therapeutic administration. Deposition of aerosol droplets or particles on the inner way of the housing of the inhalation therapy device is effectively prevented in this manner.
