Patent ID: 7984713

Claim:
A powder inhaler comprising: a device operating to supply a powder formulation, a pressure medium system operating to release a pressure medium, the pressure medium operating to form a primary aerosol with the powder formulation, a nozzle comprising a plurality of channels wherein only the pressure medium flows through at least one channel of the nozzle and the primary aerosol flows in remaining channels of the nozzle such that jets of the primary aerosol and the pressure medium are produced, the channels being arranged such that the jets of the primary aerosol and the pressure medium are directed towards one another, whereby the jets of the primary aerosol and the pressure medium at least partially impact with one another to form a secondary aerosol, and a mouthpiece in communication with the nozzle such that the secondary aerosol flows from the nozzle towards the mouthpiece, wherein the jets of the primary aerosol and the pressure medium separately have a primary flow speed, and wherein the secondary aerosol has a secondary flow speed that is lower than the flow speed of the jets of the primary aerosol, and the secondary aerosol flows towards the mouthpiece at the secondary flow speed.
