A vaporizing assembly for an aerosol-generating system may comprise a delivery device and a heater assembly. The heater assembly may comprise a heat resistive substrate and a heating element. The delivery device is configured to deliver an aerosol-forming substrate to at least a surface of the heat resistive substrate, wherein the heating element is isolated or separated from the aerosol-forming substrate by the heat resistive substrate. The present disclosure is also directed to a method for generating an aerosol.

A nasal delivery device for and a method of delivering substance to a nasal airway of a subject, the nasal delivery device comprising: a mouthpiece (519) through which the subject in use exhales to cause closure of the oropharyngeal velum of the subject; a nosepiece (517) for fitting to a nostril of a subject, the nosepiece including a nozzle (549) through which substance is in use delivered to the nasal airway; and a manually-actuatable substance supply unit (520) for delivering substance through the nozzle of the nosepiece.

Systems and methods to generate an inhalable vapor in an electronic vaporization device. Described herein are cartridges including a vaporizable material that may be securely connected to a rechargeable base unit.

Devices and methods are described for preparing, managing, and/or administering metered doses of substances for vaporized administration. In some embodiments, dose cartridges comprising at least one botanical substance include a heating element integrated into the cartridge in close contact with the botanical substance. In some embodiments, cartridge-mounted doses are stored in a magazine, optionally in carousel form, before use. Transport of a cartridge from a magazine to an electrically operated vaporizing chamber which activates the heating element is provided by a mechanical pickup means.

A breath-enhanced jet nebulizer is configured with a low liquid retention reservoir and a narrow liquid delivery passage to efficiently and efficiently aerosolize small drug volumes with minimal waste. Aerosol particles are directed through aerosol passage for delivery, although larger liquid particles are directed away from the aerosol outlet and recycled to the liquid reservoir.

An example aerosol delivery device includes a mouthpiece having an airflow outlet, and an airflow passage extending between an airflow inlet and the airflow outlet. The example aerosol delivery device further includes a housing configured to receive a cartridge that includes an aerosolizable substance and a vapor element configured to heat the aerosolizable substance, and an internal power source configured to provide electrical power. The example aerosol delivery device further includes a controller coupled to the internal power source to receive a portion of the electrical power and configured to, when the cartridge is installed at the housing, cause the vapor element of the cartridge to heat the aerosolizable substance to release an aerosol into the airflow passage during an inhalation through the airflow outlet, and a connector configured to receive power from an external source to recharge the internal power source.

Provided herein are systems for treating a subject with a pulmonary infection, for example, a nontuberculous mycobacterial pulmonary infection, a Burkholderia pulmonary infection, a pulmonary infection associated with bronchiectasis, or a Pseudomonas pulmonary infection. The system includes a pharmaceutical formulation comprising a liposomal aminoglycoside dispersion, and the lipid component of the liposomes consist essentially of electrically neutral lipids. The system also includes a nebulizer which generates an aerosol of the pharmaceutical formulation at a rate greater than about 0.53 gram per minute. The aerosol is delivered to the subject via inhalation for the treatment of the pulmonary infection.

Presented is a portable hand held e-cigarette shaped oxygen generator and air purifier. The device includes a suction body through which atmospheric air is forcibly introduced within a main body of the device during respiration, a solid oxygen filter adapted for holding solid oxygen, and a solid oxygen filter support having a dual cylindrical structure for housing and supporting the solid oxygen filter. The device further includes a solid oxygen filter support lid mountable over the solid oxygen filter support and is adapted for discharging device generated inhalable oxygen from the main body to a micro filter, a casing embodying the micro filter and operationally connected to a mouthpiece having an extension for mounting a straw. The atmospheric air introduced in the device reacts with the solid oxygen to generate inhalable oxygen after passing the atmospheric air through the dual cylindrical structure of the solid oxygen filter support.

The present disclosure relates to electronic smoking articles exhibiting improved moisture control of a reservoir contained therein. The reservoir can be formed of fibrous materials, such as cellulose acetate fiber, thermoplastic fiber, non-thermoplastic fiber, or a combination thereof. The disclosure further provides methods for forming electronic smoking articles and methods of packaging electronic smoking articles (including cartridges thereof) so as to improve moisture control of the reservoir.

Devices and methods for reducing the amount of contagions, such as germs, from the exhaled air stream of a nebulizer are provided. Specifically, a nebulizer is provided with a disinfecting chamber in communication with the exhaled air outfeed of a nebulizer that reduces the amount of contagions exiting the outfeed to the environment. An example of such a disinfecting chamber is one that employs a UVC light source.
