Abstract
A microstructured nozzle consists of a number of channels produced by microstructuring a plate-shaped member. In the nozzle the channels are located between projections which are arranged side by side in rows and project from a base plate. This microstructured base plate is covered with a cover plate. The channels are narrowly defined in terms of shape, cross sectional area and length. The nozzle contains a filter as the primary structure and a secondary structure downstream of the filter. The nozzle is used, for example, with an atomiser which produces an aerosol from a fluid containing a medicament.
