Powder inhaler having a nozzle with a plurality of channels

摘要

The invention relates to a powder inhaler ( 1 ) with mouthpiece ( 2 ) for dispersing pharmaceutical medicament formulations, which comprises an auxiliary energy source in the form of a pressure medium system ( 3 ), having a device for supplying ( 6 ) a powder formulation ( 7 ), while on activation of the pressure medium system a gaseous pressure medium ( 8 ) released by the pressure medium system ( 3 ) forms an aerosol ( 9 ) with the powder formulation ( 7 ) such that the powder particles are present in the gaseous pressure medium ( 8 ) in dispersed form. This is achieved by means of a powder inhaler ( 1 ) comprising a multi-channel nozzle, the channels of which are inclined to one another at an angle such that the aerosol jets flowing through them meet one another downstream behind the nozzle ( 10 ).
