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.
Claims20
An aerosol powder delivery device, comprising:
- a hollow device;
- aerosolizable powder adapted to produce aerosol particles within the hollow device, wherein at least a portion of the aerosol particles comprise the same material as the aerosolizable powder;
- and
- a secondary powder within the hollow device, wherein at least a portion of the aerosolizable powder, the secondary powder, or both are about 1.0 mm to about 4.0 mm in at least one dimension.
A method of producing or delivering aerosol particles, comprising:
- agitating an aerosolizable powder and a secondary powder in a hollow device to aerosolize the aerosolizable powder into aerosol particles;
- and
- passing air through an upstream end of the hollow device so as to remove the aerosol particles from a downstream end of the hollow device.
A method of making an aerosol delivery device, comprising:
- filling a hollow device with an aerosolizable powder and a secondary powder, wherein at least a portion of the secondary powder and the aerosolizable powder are larger than about 1.0 mm in at least one dimension;
- and
- sealing an upstream portion and a downstream portion of the hollow device using filters, wherein the aerosolizable powder and the secondary powder are confined within the hollow device between the filters.
An aerosol delivery device kit of component parts capable of being assembled, comprising:
- a hollow device;
- powder including an aerosolizable powder adapted to produce aerosol particles within the hollow device, wherein at least a portion of the aerosol particles comprise smaller particles of the same material as the aerosolizable powder, and a secondary powder within the hollow device, wherein at least a portion of the aerosolizable powder, the secondary powder, or both are at least about 1.0 mm in at least one dimension, wherein the powder is adapted to be positioned within the hollow device;
- and
- upstream and downstream filters, whereby the upstream and downstream filters may be positioned on the upstream and downstream end portions, respectively, of the hollow device to contain the powder within the hollow device.
