ABSTRACT:
An apparatus for production of ultra-fine homogenous aerosols, or a nebuliser, is described comprising a Coanda-plate (1) and a liquid channel (3) opening in the vicinity thereof, preferably through an orifice plate (2). The apparatus is useful for producing a micro-aerosol in medical treatment and in other fields. The aerosol is produced from a liquid film formed on the Coanda-plate, which film flows over the plate under radial thinning and breaks into small homogenous droplets at the edge of said plate. Preferably the apparatus is provided with a liquid container (5) surrounding the Coanda-plate.
