Assignee:

Philip Morris USA Inc. - Richmond VA

International Classification:

A61M015/00
A61M016/00
H05B003/00

US Classification:

12820317, 12820327, 12820315, 12820014

Abstract:

An aerosol generating device includes a housing, a heater and an optional mouthpiece. The heater volatilizes liquid within a flow passage and forms an aerosol in the mouthpiece. An aerosol confinement sleeve is disposed to control the size distribution of the aerosol.

Abstract:

Liquid aerosol formulations for generating aerosolized insulin include insulin and at least one high volatility carrier which protects the insulin from thermal degradation during vaporization of the carrier. The carrier can be a mixture of ethanol and water and the liquid aerosol formulation can be propellant free. An aerosol generating device generates the aerosolized insulin by passing the liquid aerosol formulation through a flow passage heated to convert the liquid into a vapor which entrains insulin particles which mix with air to form an aerosol. The insulin particles can be dry insulin particles produced by a hand held inhaler. By controlling the concentration of the insulin in the formulation, the size of the flow passage and/or the amount of heat which heats the flow passage, the aerosol can be provided with a selected mass median aerodynamic diameter of 1 to 3 μm or less than 1 μm so as to be delivered to a targeted portion of the lung using the inhaler.

International Classification:

A61M016/00

US Classification:

128/203260

Abstract:

An aerosol generator includes a fluid passage arranged between a first and a second layer wherein the first and second layers at least partially define the fluid passage. A liquid supply is arranged to provide a fluid in liquid phase to the fluid passage. The aerosol generator also includes a heater arranged to volatilize the fluid in the fluid passage. An outlet of the aerosol generator is arranged to receive the volatilized fluid and direct the volatilized fluid out of the fluid passage. The aerosol generator can be used to generate aerosols containing medicated materials.
