A vaporizer device (100) may be configured to adjust, based on ambient pressure, a setpoint temperature and/or a ramp rate of the vaporizer device. The setpoint temperature of the vaporizer device may be adjusted based on the ambient pressure in order to account for differences in the boiling point of a vaporizable material at different ambient pressures. Adjusting the setpoint temperature of the vaporizer device based on ambient pressure may further compensate for changes in the sensitivity of a user's taste buds in different ambient pressure and/or humidity environments. The ramp rate of the vaporizer device may be adjusted based on the ambient pressure such that the vaporizer device is able to achieve the higher boiling point of the vaporizable material in a higher ambient pressure environment in a same quantity of time as a lower boiling point of the vaporizable material in a lower ambient pressure environment.

A mist inhaler device (200) for generating a mist for inhalation by a user. The device comprises a mist generator device (201) and a driver device (202). The driver device (202) is configured to drive the mist generator device (201) at an optimum frequency to maximise the efficiency of mist generation by the mist generator device (201).

A respiratory drug delivery device and a method for automating drug delivery are provided. The respiratory drug delivery device may be utilized for delivering a drug to a patient's respiratory tract. The respiratory drug delivery device comprises an inhalation element, an air pipe, a sound sensor, and a drug delivery module, the drug delivery module delivers an aerosolized medicine when the patient inhales based on a sound signal.

The present disclosure relates to aerosol delivery devices. In various implementations, the aerosol delivery devices comprise a control device that includes a battery, a control component, and an outer housing that defines receiving chamber, and a cartridge that includes a mouthpiece portion, a tank that contains a liquid composition, and a heater configured to heat the liquid composition. The cartridge and the control device each include at least one connector configured to provide a magnetic and an electrical connection between the cartridge and the control device such that the cartridge can be removably and operatively received into the cartridge receiving chamber of the control body, wherein the at least one connector of the cartridge is located on the mouthpiece portion.

An electronic vaporizer is provided. The electronic vaporizer includes a cartridge that facilitates provision of a vaporized solution to an individual. The cartridge includes a housing that includes an interior, wherein the housing is one of a polymer housing or a ceramic housing. The cartridge also includes a heating element located in the interior of the housing, wherein the heating element is configured to vaporize a solution for oral provision to the individual. The vaporizer may also include a power harvesting device operative to acquire energy from the environment for use with powering the heating element.

A heating assembly for a vapour generating device includes a heating device arranged to heat, in use, a body, the body including a vaporisable substance located in use in a heating compartment of the heating assembly, the heating assembly being arranged to supply, in use, power to the heating device to heat the body; a temperature sensor arranged to monitor, in use, a temperature related to heat generated from the body, temperature information related to heat generated from the body being determinable from the monitored temperature; and a memory accessor arranged to access, in use, a memory that holds a relationship between the temperature information, the amount of power supplied to the heating device or the profile of power supplied to the heating device, and at least one condition including an age of the body, or a type of the body, or the presence of the body.

An attachment for monitoring an inhaler usage to be used for monitoring a usage frequency of patients using inhalers is provided. The attachment allows monitoring the inhaler usage of the patients and provides a low energy consumption. With an effective power management system developed with the attachment, the attachment is used for a longer period of time without a need for a battery replacement.

A test fixture for testing aerosol provision devices may include a housing, a plurality of testing modules disposed at the housing where each of the testing modules includes a cavity configured to receive a portion of an aerosol provision device, and processing circuitry operably coupled to the testing modules. Each of the testing modules may be configured to interface with an assembly of a respective one of the aerosol provision devices to transition the assembly between an initial state and a transitioned state during a functional test controlled by the processing circuitry. The processing circuitry may be configured to conduct the functional test of at least two of the testing modules simultaneously.

Provided is a system comprising at least one inhaler. Each of the at least one inhaler comprises a use determination system configured to determine at least one value of a usage parameter relating to use of the respective inhaler by a subject. The system further comprises a user interface and a processing module. The user interface is configured to enable user-inputting of an indication of a status of a respiratory disease being experienced by the subject. The processing module is configured to control the user interface to issue a prompt to input the indication based on the at least one value.

An apparatus is provided to change the absolute humidity of a flow of air for delivery to an entrance of the airways of a patient, the change being compared to the absolute humidity of ambient air. The apparatus has a reservoir configured to hold a volume of liquid. A heating element creates vapour from the liquid. A chamber is provided to mix the flow of air with the vapour. The apparatus has a body having a first wall structure with a chamber inlet port. A closure element having an air inlet port for pneumatically connecting to a source of the flow of air is secured to the body to provide a sealed gas flow path between the air inlet port and the chamber inlet port, and a liquid trap in the gas flow path.
