Abstract

Un método para aerosolizar un medicamento en polvo que comprende acoplar un extremo de entrada de polvo de un tubo de alimentación con una penetración en un receptáculo que contiene polvo. El polvo es arrastrado en dirección ascendente a través del tubo y dispersado en una corriente de gas de alta presión que fluye por una porción del tubo de alimentación. El aparato comprende el tubo de alimentación montado dentro de una envoltura base próxima a un sujetador para uno o más receptáculos, que puede tener la forma de un cartucho que contiene una pluralidad de receptáculos formados en una membrana continua el cartucho puede ser movido alternativamente en relación al tubo de alimentación y un mecanismo de perforación indeprendiente para secuencialmente perforar el receptáculo y a continuación acoplar el tubo de alimentación a través de la penetración producida para extraer el polvo. Como alternativa, la o las penetraciones a través del receptáculo pueden estar formadas al acoplarse eltubo de alimentación, o algunas penetraciones puedan estar formadas antes de acoplarse con otras penetraciones formadas en el momento del acoplamiento.A method of aerosolizing a powder medicine comprising coupling a powder inlet end of a feeding tube with a penetration into a receptacle containing powder. The powder is drawn upward through the tube and dispersed in a high pressure gas stream that flows through a portion of the feed tube. The apparatus comprises the feeding tube mounted within a base casing next to a holder for one or more receptacles, which may be in the form of a cartridge containing a plurality of receptacles formed in a continuous membrane the cartridge may be alternately moved relative to the feed tube and a separate piercing mechanism to sequentially pierce the receptacle and then couple the feed tube through the penetration produced to extract the powder. Alternatively, the penetration (s) through the receptacle may be formed by coupling the feed tube, or some penetrations may be formed before coupling with other penetrations formed at the time of coupling.
