Abstract: The powder dispersion device has a chamber (10) housing a block (12) of compacted powder, with a piston (14) exercising pressure on the block. A pressurized gas stream is directed onto the block on the side opposite the piston. The gas gathers powder and is directed through a passage (18) past a tapered needle (40) that controls the flow and deflects the stream to outlet passages (22).

Abstract: The inhaler (1), using a dry powder as the medication, has a reservoir (2) or replaceable cartridge to hold the powder (3), and a moving piston (7) with a spring which pushes the powder towards an outlet opening (4) from the reservoir. A gas system (8,9,12,19,20) injects a set volume of gas into the reservoir, to propel the required powder dosage towards the outlet.
