Abstract: A portable device that accurately determines the liquid dosage that a patient is consuming while also regulating their use of the device is provided and is suitable for use with substances like medical cannabis and opioids. A liquid dispenser device is reusable with replaceable liquid cartridges. These cartridges can contain multiple dosages of a specific liquid, which is more convenient for the patient and reduces cost. The device uses a micro-motor, translational screw, and encoder to determine the exact amount of liquid displaced from the cartridge. That exact amount of liquid is dispensed from a small nozzle into a mouthpiece. The mouthpiece is replaceable and can be tailored to meet the patient's specific needs. For example, the mouthpiece can be adapted for dispensing under the tongue of the user or directly into a drink. The device can also have locking mechanisms and wireless communication capabilities.

Abstract: 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.
