The distal end of the mouthpiece is configured to engage the proximal end of the tank, and when the cartridge is coupled with the aerosol delivery device at least one feature of the cartridge, or at least one feature of the control device, or at least one feature of both the cartridge and the control device, provides a visual indication of a color associated with the distinctive characteristic.

A nasal delivery device for delivering substance to a nasal cavity of a subject, the delivery device comprising: a substance supply unit for supplying a dose of substance to be delivered to the nasal cavity of the subject, the substance supply unit including an inlet and an outlet; a nosepiece unit including a nosepiece for fitting to a nasal cavity of the subject and being in fluid communication with the outlet of the substance supply unit; and a mouthpiece unit including a mouthpiece in fluid communication with the inlet of the substance supply unit and through which the subject in use exhales such as to entrain substance from the container chamber and deliver the same through the nosepiece, and at least one temperature modifier for reducing a temperature of the exhaled air flow such as to reduce the absolute humidity thereof.

A power supply unit includes: a power supply configured to discharge power to a load for generating an aerosol from an aerosol generation source; a charger configured to convert inputted power into charging power; a temperature measuring unit configured to measure a temperature of the power supply; and a charging controller configured to perform a first control for stopping the charger from supplying the charging power to the power supply and a second control for causing the charger to supply the charging power to the power supply, the charging controller setting a duty ratio to a value greater than 0 and smaller than 100 in a case where the temperature of the power supply is within a predetermined range, and the duty ratio being obtained by dividing a time during which the charging controller performs the first control by a unit time.

A pulmonary delivery system includes an elongated body having an openable and closeable portion thereof for receiving an insertable and replaceable container such as a cartridge of pure medical product disposed in a saline solution. The medical product may be epinephrine, insulin or nicotine disposed in a saline solution. The system also incorporates a penetrating element that is disposed in the cylinder to pierce the cartridge and release the nicotine solution into the cylinder and into or on a micron mesh grid. A flow of air created by inhaling through a mouthpiece draws air into an individual's lungs from an entrainment port and onto a grid for atomizing a mist of micron droplets through the grid. It is recognized that the air from the entrainment port further dilutes the concentration of the medical product. The grid is connected to a source of electrical power to vibrate the mesh grid.

A battery-operated foam inhalation device which comprises a cartridge (610) having a liquid for producing a foam and a foam outlet (654). Agitation means agitates the liquid to produce the foam, and the agitation means comprises an electric motor (762) and a battery (760) for energising the electric motor (762). A carrier (672) receives the cartridge (610) and has a carrier foam inlet (680) for fluid communication with the foam outlet (654) of the cartridge (610). A carrier foam outlet (682) dispenses the foam to a user.

A nebulizer and a nozzle thereof are provided. The nozzle has a containing seat and a cover. The containing seat has an air conduit. The air conduit has an input terminal and an output terminal. The cover has a guiding channel and an impediment. An input opening is formed in the nozzle for introducing air. A first opening of the guiding channel is disposed near the output terminal and the input opening is disposed far of the output terminal. The impediment is disposed in front of the output terminal and has a plane. Air emitted from the output terminal lashes the plane and then flows to a second opening of the guiding channel, and the air of the input opening is guided to the first opening for decreasing a whole resistance of the nozzle, and thereby increasing nebulization efficiency.

An apparatus includes a housing including a power source; a reservoir including an inlet, an outlet, and configured to contain vaporizable material and couple to the housing; and a PTCR heating element configured to electrically couple to the power source and heat the vaporizable material to form an aerosol. The PTCR heating element includes an electrical resistivity that varies based on temperature. The electrical resistivity includes an electrical resistivity transition zone including an increase in electrical resistivity over a temperature range such that, when the PTCR heating element is heated to a first temperature within the transition zone, current flow from the power source is reduced to a level that limits further temperature increases of the PTCR heating element. Related apparatus, systems, techniques, and articles are also described.

The invention provides an apparatus for use in aerosolized delivery of a powder, and comprises a first chamber containing gas at a first pressure higher than atmospheric pressure, and a second chamber containing gas at a second pressure higher than atmospheric pressure. The apparatus also comprises a powder, contained within the first or second chamber. The first chamber has a first external wall and a separating wall, the separating wall being shared with the second chamber. The first external wall or the separating wall is configured to rupture if the pressure difference across it becomes equal to or greater than a threshold pressure difference. In particular, the apparatus is configured so that the difference between the second pressure and atmospheric pressure is greater than the threshold pressure difference. In an initial state, the apparatus is configured such that the difference between the second pressure and the first pressure is less than the pressure difference required to rupture the separating wall, and the difference between the first pressure and atmospheric pressure is less than the pressure difference required to rupture the first external wall.
