Abstract
A method based on an Air-razor tool is disclosed thereby providing de-aggregation and dispersal into air of a dose of finely divided medication powder. In sucking air through a nozzle, particles of a powder dose made available to the nozzle, are gradually de-aggregated and dispersed into a stream of air entering the nozzle. The gradual de-aggregation or dispersal is produced by a relative motion introduced between the nozzle and the dose. In a preferred embodiment, the powder is deposited onto a substrate, occupying a larger area than the area of the nozzle inlet. The nozzle is preferably positioned outside the powder area, not accessing the powder in its relative motion until a created air stream entering the nozzle, exceeds a threshold flow velocity.
