Abstract

A woven or non-woven screen mesh disc impregnated at spaced locations along its circumference with a dose of powdered medicament. The disc is selectively indexed so as to present the impregnated doses of medicament seriatim between a pair of holes in an upper and lower pressure plate in an inhalator.
Air is forced through the holes in the pressure plates and the encapsulated screen mesh to entrain a dose of the powdered medicament, which is then inhaled through a mouth piece, by the patient-user. Because the powdered medicament is impregnated into the screen mesh, the air impinging upon the mesh and the powdered medicament will cause the medicament to break up as it is pressed up against and passed through the mesh infrastructure to aerosol of atomize the same so that the medicament is presented in appropriate particle sizes for maximum benefit when inhaled.
