APPARATUS AND METHODS FOR DISPERSING DRY POWDER MEDICAMENTS

摘要

A method for aerosolizing a powdered medicament comprises coupling a powder inlet end of a feed tube (14) with a penetration in a receptacle (12) containing the powder. Powder is drawn upward through the tube and dispersed in a high pressure gas stream flowing past a portion of the feed tube. Apparatus comprises the feed tube mounted within a base enclosure proximate a holder for one or more receptacles, which may be formed in a continuous web placed in a cartridge (22). A separate piercing mechanism (26) may be provided.
