DEVICE FOR MORE EFFECTIVE PULVERIZATION OF A POWDERED INHALATION MEDICAMENT

摘要

A device for carrying out a more efficient spraying of particles and / or agglomerates of a powdered medicament taken by inhalation, comprising a chamber (2) for containing said medicament. Said chamber substantially closed at one end, is provided with at least one opening permitting entry of air and an opening for the output of the powdered medicament. The chamber (2) is either of symmetrical form in rotation, or it has a cross section perpendicular to its central axis, said section being substantially circular and having no obstruction to flow. The inlet and outlet openings are spaced apart from each other in the direction of the central axis of said chamber (2), the inlet opening (1) being designed to send the flow air to the vortex chamber, which is essentially parallel to the tangent.
