The present invention provides for the integration of drug dispersion methods into a drug or medicine delivery system. The drug dispersion methods used include shear (e.g., air across a drug, with or without a gas assist), capillary flow or a venturi effect, mechanical means such as spinning, vibration, or impaction, and turbulence (e.g., using mesh screens, or restrictions in the air path). These methods of drug dispersion allow for all of the drug in the system to be released, allowing control of the dosage size. These methods also provide for drug metering, fluidization, entrainment, deaggragation and deagglomeration. The present invention also provides for the integration of a drug sealing system into the device. The drug sealing system provides a way of blocking the migration of drug from one area of the package to another. The drug seal system can also provide a method of tightly containing the drug until the package is opened, of directing airflow through the package and of managing and containing the drug during the package/device manufacturing process.

An arrangement for an inhaler comprises at least one electric evaporator for evaporating liquid supplied from the evaporator, and for adding the evaporated liquid to an air flow flowing through the inhaler to form an aerosol, and a flow rate measuring arrangement for measuring the volume and/or mass flow of the air flow flowing through the inhaler. The flow rate measuring arrangement comprises a heating device, a downstream temperature sensor arranged downstream of the heating device for measuring an air outlet temperature and an electronic control device, wherein the electronic control device is adapted to determine the volume and/or mass flow of the air flow flowing through the inhaler on the basis of a temperature difference between the air outlet temperature and an air inlet temperature of the air flow upstream of the heating device.

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.

A vaping atomizer for use with a vaping device is provided. The atomizer includes an enclosure portion and a heating-element housing extending through the interior of the enclosure portion. A first cavity for receiving vaping liquid is at least partially formed between the enclosure portion and the heating-element housing. The heating-element housing includes at least one aperture formed therein facilitating transfer of the vaping liquid from the first cavity to a second cavity formed on the interior thereof. The at least one aperture formed in the heating-element housing can be generally shaped as a triangle. The size and shape of the least one aperture can be optimized to prevent the vaping liquid from flooding the interior cavity, and to accommodate uses of various vaping liquids having different viscosities, as well as to prevent liquid-absorbing material provided in the second cavity from drying out to prevent dry hits during use of the vaping atomizer.

Device for dispensing a pulverulent product comprising a reservoir unit (100) connected on the one hand, to an air expulsion system (200) and on the other hand to a dispensing head (300) provided with a dispensing orifice (310), said reservoir unit (100) comprising a reservoir (110) having substantially the form of a hollow cylinder, with a distal opening (111), a proximal opening (112), and a metering passage (113) connecting said distal and proximal openings (111, 112), a one-way valve (115) being positioned between said metering passage (113) and said distal opening (111), said proximal opening (112) of said reservoir (110) forming a filling cone which tapers towards said metering passage (113) to facilitate filling of said metering passage (113) with a dose of powder.

A smoking substitute apparatus comprising an air passage, a reservoir formed from an air-permeable substrate and arranged to allow air to be drawn through the reservoir, the reservoir being loaded with a source of nicotine, and one or more one-way valves arranged along the air passage and configured to allow air to flow along the air passage in an upstream to downstream direction.

A vaporiser insert for an electronic cigarette product comprises at least one electrical vaporiser for vaporising fluid supplied to the vaporiser and for supplying the vaporised fluid to an airflow, a main part having a lateral face which surrounds an airflow duct through which the airflow can flow, at least one fluid opening for supplying vaporisable fluid from the outside into the vaporiser insert and to the vaporiser being arranged on the lateral face of the main part. The vaporiser insert comprises a support for retaining the vaporiser, and the support comprises a passage opening that corresponds to the fluid opening in order to supply fluid to the vaporiser.

In one embodiment, the electronic vaping device includes a cartridge and a battery section. The cartridge and the battery section are connectable so as to define an air inlet between a portion of the cartridge and a portion of the battery section.

An inhaler comprising a valve having a valve volume of no more than 40 micro liters and a valve having a first layer comprising a silane and a second layer comprising a polyfluoropolyether silane—and albuterol.

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.
