Vaporizer cartridges and vaporizer apparatuses, and methods for making, using and delivering vapor to a user, that are leak-resistant for use with cannabinoids. In particular, described herein are leak-resistant vaporizer cartridges and apparatuses adapted for use with oil-based vaporizable materials including cannabis oils.

A system includes a converter configured to electrically couple to a power source and to a heating element of a vaporizer atomizer. The converter can be further configured to receive a first voltage from the power source and provide a second voltage to the heating element. The converter can be a direct-current to direct-current converter. A power monitor configured to electrically couple to the heating element, measure a current through the heating element, measure a voltage over the heating element, calculate a power and/or resistance, and output a control signal to the converter. The converter can be configured to be controlled by the control signal to vary the second voltage to maintain a target power or a target temperature over the heating element. Related apparatus, systems, techniques and articles are also described.

Disclosed herein is a nebulizer comprising of a medicine cup reservoir containing an aqueous pirfenidone solution a medicine cup reservoir cap, an aerosol generator, an aerosol mixing chamber to which freshly generated aerosol resides until inhaled, a one-way inhalation valve, a mouthpiece and a one-way exhalation valve. The invention allows atmospheric pressure to be maintained inside the medicine cup reservoir during nebulization and optimizes the volume of the aerosol mixing chamber to minimize freshly generated aerosol inter-droplet collision, impaction of aerosol to the aerosol mixing chamber wall, droplet growth and/or condensation during exhalation, prior to inhalation, or during inhalation. The larger aerosol mixing chamber volume also allows the aerosol to accumulate during the exhalation phase. Despite venting producing a larger generated aerosol droplet population mean compared to the non-vented aerosol generator, The combined effect of the invention increases device output rate of respirable aerosol droplets, increases pirfenidone Cmax and AUC to improve treatment or prevention of various diseases, including disease associated with the lung, heart and kidney, including fibrosis, inflammatory conditions and transplant rejection.

An aerosol generator device has an elongate body with an interior passageway extending longitudinally to its mouth end. The device receives an interchangeable, pressurized canister charged with a nicotine containing liquid that is discharged in a metered dose on manual actuation of a button member that causes a valve in the canister to open and discharge through a discharge tube. A sleeve releasably couples the canister to the body. The button member is slidably mounted on the body for reciprocal movement along a trigger axis Y-Y′ extending transversely of the longitudinal axis X-X′ of the device, and has a manually depressible surface portion and a camming surface portion that drives a slidable nozzle member to press the discharge tube inwardly of the canister to open its valve and release liquid into the nozzle member. Nozzle forms an aerosol from the liquid, which is delivered to the consumer through outlets in the mouth end of the device.

The present invention relates to an inhalation device used for inhalation of the medicament in dry powder form from capsules.

The present disclosure relates to an aerosol delivery device that includes a reservoir housing that defines a mouthpiece channel. The aerosol delivery device includes a sealing member configured to be received within the reservoir housing to define a reservoir chamber configured to retain an aerosol precursor composition therein. The aerosol delivery device also includes a substrate member that is configured to be received within the reservoir housing and to be directly engaged with a vaporizing assembly for forming an aerosol. The reservoir housing, sealing member, substrate member, and/or vaporizing assembly can be used for forming aerosols with precise and reproducible compositions.

An aerosol-generating device includes a housing having a first end defining a mouthpiece, a second end, and a cavity defined between the first end and the second end. The device also includes a reservoir within the cavity. The reservoir is configured to store a liquid aerosol-forming substrate. The device also includes an atomizer and a valve within the mouthpiece of the housing. The valve has a first side and an second side. The second side of the valve includes a hydrophilic coating, a hydrophobic coating, or both a hydrophilic coating and a hydrophobic coating.

A cartridge for an electrically operated aerosol-generating system is provided, the cartridge including: a liquid storage portion including a housing holding a liquid aerosol-forming substrate, the housing having an opening; and a fluid-permeable heater assembly including a plurality of electrically conductive filaments, the fluid-permeable heater assembly being fixed to the housing and extending across the opening of the housing. An aerosol-generating system, and a method of manufacture of a cartridge for an electrically operated aerosol-generating system, are also provided.

Disclosed is a drug vaporization and inhalation device. The present invention is configured such that when an infected patient with asthma, a coronavirus, or the like inhales a particulate drug, the drug is contained in vaporized steam, and therefore, the drug can sufficiently arrive at the lungs of the infected patient with asthma, a coronavirus, or the like, without loss, thereby preventing a given amount of the drug from remaining in an inhalation container and improving the drug inhalation efficiency of the infected patient with asthma, a coronavirus, or the like along with prevention of excessive inhalation of the drug.

The disclosure relates to an oven assembly configured for use with a personal electronic vaporizer. Some versions of the oven assembly may include features such as a base, an outer wall extending from the base, a first chamber defined by the outer wall and the base, an oven element disposed in the first chamber, a second chamber defined by the oven element, and at least one opening defined by the oven element. Some versions of oven assembly may be configured to pass heated air therethrough. Some versions of oven assembly may include features such as a heating element disposed in the chamber and configured to be electrically coupled with the vaporizer when the oven assembly is disposed in an oven receiving area of the vaporizer. The heating element may be configured to heat air within the chamber.
