Embodiment Construction

[0019] An aerosol powder delivery device is provided wherein an aerosolizable powder is contained in a hollow device for aerosolization into aerosol particles for inhalation. To aerosolize the aerosolizable powder, the hollow device can be mechanically shaken by the consumer to break up or break up the aerosolizable powder into aerosol particles. The disintegration or fragmentation of the aerosolizable powder can take place by impact of the powder particles with other powder particles or with the walls of the hollow device.

[0020] figure 1 An exemplary embodiment of an aerosol powder delivery device 100 is provided in . figure 1 Among them, the aerosol powder delivery device 100 is a hollow device, a hollow elongated device or a tube, including an upstream filter 110, an aerosolizable powder 120, an auxiliary powder 130, a downstream filter 140 and an optional auxiliary filter 150, so The optional auxiliary filter 150 described above can be provided at the optional nozzle ...

Abstract

An aerosol powder delivery device, a method of producing or delivering aerosol particles, a method of making a delivery device, and an inhaler kit are provided. The device can be used to produce an aerosolizable powder by breaking or deagglomerating the aerosolizable powder into aerosol particles for inhalation. The aerosol particles can be produced by mechanically agitating or shaking a hollow device with the aerosolizable powder and a second powder to mechanically break or loosen aerosol particles from the aerosolizable powder. Thus, a small, lightweight, simple, sealed and stable device without complex moving parts, external power sources or heat is provided to aerosolize powder into aerosol particles for transmucosal delivery into a mouth upon inhalation.

Description

[0001] This application claims priority under 35 U.S.C. §119(e) from U.S. Provisional Patent Application No. 60 / 754,192, filed December 28, 2005, the entire contents of which are incorporated herein by reference. Background technique [0002] Dry powder pharmaceutical inhalers (DPIs) are used to deliver medicines in aerosol form by inhalation. DPIs typically contain dry drug powders. When the patient performs an inhalation maneuver, the DPI aerosolizes drug powder mixed in and carried away by the air stream for delivery to the patient's airway. [0003] For example, DPI can aerosolize dry powders by using a brush to grind the powder (see US Patent No. 5 441 060) or by impinging larger particles within a baffle (see US Patent No. 5 699 789). However, since DPI devices typically require particles at the micron scale (approximately 1 to 5 microns for lung deposition) and specific doses, these DPI devices utilize complex mechanisms to control aerosol particle size and dose levels...
