A device and an arrangement are disclosed, which create a powder Air-razor, which
into an inhalation air volume de-aggregates and disperses a finely divided medication
powder. The powder is generally loaded onto a dosing member intended for use with
an inhaler. By sucking air through a mouthpiece connected to a nozzle, particles
of the load of powder are gradually de-aggregated, dispersed and continuously released
into the sucked air during a defined interval. The gradual de-aggregation and dispersal
of the medication powder is generated by a relative motion introduced between the
nozzle and the dosing member. The powder is generally loaded onto a larger area
than the area of the air nozzle inlet. The nozzle may be positioned outside the
dose area until an air stream has begun to flow into the nozzle by suction of air
in an inhaling operation.
