A vaporizer device for the administration of a substance to a user as a vapor comprises a housing and a mechanism for delivering a vapor. The mechanism is located within the housing. The housing comprises one or more air intake openings, at least one air exit opening, at least one control button and a display screen. The mechanism for delivering a vapor comprises a translational screw in contact with a micro motor, a cavity adapted to engage a liquid-containing cartridge, a heating chamber adapted to receive a liquid from the liquid-containing cartridge, a heating element adapted to provide heat to the heating chamber, a first air channel in communication with the one or more air intake openings and the heating chamber, and a second air channel in communication with the heating chamber and the at least one air exit opening. A method of administering a vapor to an individual includes use of the vaporizer device where the vaporizer device is adapted to receive control instructions. A liquid-filled cartridge is provided which is adapted to be inserted into the cavity such that the cartridge can be placed in contact with the translational screw. The liquid-filled cartridge is inserted into the vaporizer; and a vapor provided by the vaporizer device is inhaled. The vaporizer device accurately determines the dosage that a patient is inhaling while also regulating their use of the device. This Volume Displacement Dosage Vaporizer is a reusable device with replaceable liquid cartridges. These cartridges can contain multiple dosages of a specific liquid, which is more convenient for the patient and reduces cost. Since the dosage is pre-measured while in liquid form, the air flow/suction force of the vapor does not affect the dosage. The device can also have locking mechanisms and wireless communication capabilities. The device will not allow patients take over the maximum doctor recommended dosage, and regulates the time interval of those dosages based on doctor recommendation. wireless communication can be used to communicate with other devices to ensure that the patient is not overlapping their dosages while using other devices. Wireless communication can also be used to sync the device to a smartphone, tablet, or computer app to track patient data, usage, and the patient can also set a timer/alarm.

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 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.

An atomizing assembly includes a tubing section having an inlet end and an outlet end. The inlet end of the tubing section is connectable to a liquid storage portion, and the outlet end of the tubing section is in fluid communication with an atomizing nozzle. The tubing section is configured to deliver a flow of liquid aerosol-forming substrate through the atomizing nozzle. The atomizing nozzle includes an air channel configured to establish an air flow through the nozzle. The air flow is mixed with the flow of liquid aerosol-forming substrate.

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.

An electronic cigarette includes a battery assembly and an atomizer assembly within a housing with the battery assembly electrically connected to the atomizer assembly. The housing has one or more air inlets. A liquid storage component is in contact with a porous component of the atomizer assembly, with the porous component having a run-through hole. A heating wire is in an air flow path through the run-through hole.

An inhaler device for pulmonary delivery of at least one substance from a drug dose cartridge to an inhaling user, including: a first conduit for conducting a carrier airflow to a proximal opening of a mouthpiece for use by the user, a holder configured to position the dose cartridge within the carrier airflow; and a second conduit for conducting a shunting airflow to the mouthpiece without passing through the dose cartridge position. In some embodiments, a controller connected to a valve controls a rate of carrier airflow, for example by controlling the shunting airflow, based on a sensor indication of airflow rate and a target airflow profile.

A dose unit including at least one isolated bioactive agent applied on a carrier material in thermal contact with an electrically heating element configured to vaporize a pre-determined amount of the agent for pulmonary delivery thereof is provided herein, as well as devices for effecting vaporization and pulmonary delivery of the isolated agent, and methods for preparing the dose unit, controllably releasing the agent therefrom, methods for pulmonary delivery thereof and methods of treatment of medical conditions treatable by pulmonary delivery of the isolated bioactive agent.

Cartridges for generating an aerosol are provided. In some implementations, a cartridge comprises a body, a heating element, and a mouthpiece. The body includes a storage compartment configured to hold a vaporizable material and has a first end, a second end, and a surface between the first end and the second end. The mouthpiece is secured over the first end, has a notch extending away from the second end towards the first end, covers a first portion of the surface, does not cover a second portion of the surface configured for insertion into a cartridge receptacle of a vaporizer device, and does not cover a third portion of the surface comprising an area between the notch and the second end, the third portion of the surface being visible when the second portion of the surface is inserted into the cartridge receptacle.

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.
