An aerosol generator for generating an aerosol from a fluid, comprising: a vibratable membrane having a first side for being in contact with the fluid and an opposite second side, the membrane having a plurality of through holes penetrating the membrane in an extension direction from the first side to the second side, whereby the fluid passes the through holes from the first side to the second side when the membrane is vibrated for generating the aerosol at the second side, each through hole having along its extension direction a smallest diameter, a larger diameter that is larger than the smallest diameter and defined by that diameter that is closest to triple, preferably twice said smallest diameter, each through hole having a nozzle portion defined by that continuous portion of the through hole in the extension direction comprising the smallest diameter of the through hole and bordered by the larger diameter of the through hole, wherein the ratio of the total length of each through hole in the extension direction to the length of a respective one of said nozzle portions in the extension direction is at least 4, preferably at least 4.5 and most preferred equal to or larger than 5.

A pacifier comprising a suction part and a housing part, wherein said suction part comprises a nipple and a shield connected to each other, wherein said suction part comprises a passageway through which a fluid can pass from outside a mouth of a user of the pacifier to inside the mouth of the user of the pacifier, and wherein said housing part comprises a housing, wherein said housing is prefilled with a drug which can pass through the passageway into the mouth of the user when the housing part is connected to said suction part and wherein said drug is a drug to be inhaled through the passageway of the suction part.

Systems, methods and apparatuses for aerosolizing all or substantially all plant matter, medications, flavors, smells, liquid and/or other material to be aerosolizing are disclosed. Embodiments of the invention comprise an aerosolization chamber sealed except for two or more conduits, a first conduit coupled to a source of fully or almost fully oxygenated gas, a heating element capable of heating the aerosolization chamber to a temperature above a combustion temperature, a second conduit configured to transport aerosolized gases and elements out of the chamber and, in one implementation, at least one valve positioned in the second conduit preventing the flow of atmospheric air into the vaporization chamber. In some instances, the first gas substantially clears the vaporization chamber of atmospheric air prior to reaching combustion temperature. A second gas containing oxygen may be intermixed with the vaporization gases and vaporized elements proximal to the combustion chamber.

An aerosol generating system includes a heater assembly and a manually operated pump. The pump includes a hollow member with an inlet portion and an outlet portion. The inlet portion of the hollow member is configured connectable with a liquid storage portion. The outlet portion of the hollow member is in fluid communication with a dispensing assembly. The pump is configured to dispense a liquid material onto the heater assembly. The pump is configured to pump the liquid material from the liquid storage portion via the dispensing assembly and onto the heater assembly.

Apparatus and methods for generating an inhalable medium are disclosed. An apparatus includes a container for holding a liquid, a heater for volatilizing liquid held in the container to generate a flow of at least one of a vapor and an aerosol in use, and a receptacle for receiving material. The receptacle is located adjacent to the heater such that in use, material received in the receptacle is heated by the heater. One or more constituents of material received in the receptacle in use are mixed with the flow of at least one of a vapor and an aerosol in use to produce the inhalable medium.

A steam inhaler includes a steam chamber housing having mounted therein a heater assembly. The steam chamber housing defines a steam chamber adapted to receive water. A fitting mounted to the steam chamber housing has a steam conduit section extended toward an exterior vent opening, a nozzle conduit section extended from the steam conduit, and a fresh air conduit section extended from the steam conduit section at a location downstream of the nozzle conduit section. The fitting is configured such that steam flows freely from the steam chamber, through the steam conduit section toward the exterior vent opening, a suction provided at the nozzle redirects at least a portion of the steam into the nozzle conduit section toward a mask, and the fresh air conduit directs fresh air into the steam conduit section to reduce a temperature of the steam exiting the exterior vent opening.

An aerosol-generating system may include a liquid storage portion configured to hold liquid aerosol-forming substrate, a vaporizer including a heating element with an internal passage at least partially defined by a surface of the heating element, and a micro pump configured to deliver liquid aerosol-forming substrate from the liquid storage portion to the internal passage of the heating element, such that the vaporizer is configured to heat the delivered liquid aerosol-forming substrate at the internal passage to a temperature sufficient to volatilize at least a part of the delivered liquid aerosol-forming substrate. The micro pump may be configured to deliver a particular amount of liquid aerosol-forming substrate to the internal passage based on the micro pump performing an individual pump cycle.

A substance delivery device and methods to promote treatment regimen compliance. A beneficial substance and an addictive substance are administered from a device delivering the substances by a user inhaling vaporized or atomized beneficial substances and addictive substances.

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.

A compact modular multifunctional inhalation device including a housing having an inlet port and an outlet port; a removable cartridge module adapted to seat within the housing, the cartridge including: a tray within the cartridge for holding a solid inhalant, a heating element mounted within the cartridge above and through the tray for heating the inhalant; and a removable modular electronic circuit adapted to seat within the housing to provide electrical current to the heating element. The heating element is a coil mounted within a chamber in thermal proximity to the solid inhalant. A quartz rod is mounted within the coil. A plunger is mounted within the cartridge to translate therein and compact the solid inhalant. In an alternative embodiment, dual channels and outlet ports are mounted in communication with an inlet port. In another embodiment, the cartridge is a split chamber cartridge with a split plunger mounted therein.
