An improved medicant delivery system is disclosed wherein the carrier for the medicant is a fluid that can be atomized or vaporized by exposure to heat. The system provides for repeatable dose of medicant, can be stored in any orientation, and/or has an ability to maximize energy efficiency.

An elongated aerosol-generating device configured to receive an aerosol-generating article is provided, including a heater extending longitudinally with respect to the device, being configured to heat the article and to penetrate an internal portion thereof; and an extractor configured to extract the article received in the device, being movably coupled to the device between operating and extraction positions, the operating position defined by the heater contacting the article, and the extraction position defined by the heater separated from the article, the extractor including a cavity to receive the article, a first aperture through an end-wall of the cavity and being configured to allow the heater to penetrate the cavity when the extractor is moved between the extraction and operating positions, wherein the extractor further defines an air-flow channel to allow air flow into the cavity, an inlet of the channel being positioned radially-outward of the first aperture.

A fluid dispenser device having a reservoir; a valve; a cocking member movable between rest and primed positions and between primed and dispensing positions, the cocking member includes a set of teeth; a blocking device blocking the cocking member in the primed position; a trigger system controlled by inhaling to release the blocking device; a reservoir support element including a cam opening; and a meshing wheel having a toothed projection co-operating with the set of teeth and a cam projection co-operating with the cam opening. The toothed projection is centered relative to the wheel rotation axis, and the cam projection is offset relative to the axis. The meshing wheel completes a turn when the cocking member moves from its primed towards its dispensing position, such that the cam projection causes the reservoir support element to perform reciprocating axial movement for actuating and returning the valve into its rest position.

A droplet delivery device and related methods for delivering precise and repeatable dosages to a subject for pulmonary use is disclosed. The droplet delivery device includes a housing, a reservoir, and ejector mechanism, and at least one differential pressure sensor. The droplet delivery device is automatically breath actuated by the user when the differential pressure sensor senses a predetermined pressure change within housing. The droplet delivery device is then actuated to generate a stream of droplets having an average ejected droplet diameter within the respirable size range, e.g, less than about 5 μm, so as to target the pulmonary system of the user.

An example aerosol delivery device includes a mouthpiece having an airflow outlet, and an airflow passage extending between an airflow inlet and the airflow outlet. The example aerosol delivery device further includes a housing configured to receive a cartridge that includes an aerosolizable substance and a vapor element configured to heat the aerosolizable substance, and an internal power source configured to provide electrical power. The example aerosol delivery device further includes a controller coupled to the internal power source to receive a portion of the electrical power and configured to, when the cartridge is installed at the housing, cause the vapor element of the cartridge to heat the aerosolizable substance to release an aerosol into the airflow passage during an inhalation through the airflow outlet, and a connector configured to receive power from an external source to recharge the internal power source.

An fluid sensor to activate and control various components of an inhalation device. The fluid sensor includes an acoustic element, such as a microphone, positioned within said inhalation device to detect fluid within the device and output signals representative of the frequency, direction and/or amplitude of the fluid. These signals control and activate an electrostatic plate and/or a high frequency vibrator.

An inhaler/puffer is provided. The inhaler/puffer may comprise a body, a cap, and a base, the cap and the base being configured to functionally engage the body. The body may define a chamber wherein minerals, such as salt, may be housed. The body, cap, and base may be configured to permit a user to inhale on the cap and draw air through the base into the chamber, over the minerals, through the cap and into the respiratory system of the user. Additionally, the inhaler/puffer may be placed in-line with an oxygen breathing system, such that as the breathing system provides oxygen to the user, the user also receives salt air treatment.

Disclosed herein is a device configured to impart flavoring to an airstream admitted the device prior to the airstream reaching an aerosol generator of the device, the device thereby operable to deliver a flavored aerosol from an outlet.

Novel nebulizers and methods are provided for a nebulizer including a dialable negative pressure threshold valve that actuates in response to different negative pressures corresponding to different negative pressure threshold settings of actuation of the valve to influence inhalation effort, aerosol entrainment, and aerosol delivery.

An inhaler housing (14) for an inhaler (10) for inhaling inhalable substances, the inhaler having: a body (14) and a dose counter (24) with a return spring (28), wherein a distinct guide surface (162) is provided for guiding the end of the return spring into a recess (152), the distinct guide surface being wider than an entrance mouth (160) of the recess, a dose counter chamber (22) being provided which is separated from a tubular interior space (182) of the inhaler by a barrier (180), the barrier including a stepped upper wall area (184) including at least three steps (186, 188, 190, 192) at different levels, the inhaler having a valve stem block (62) having an inner bore and a valve stem block having a seal (224) in the inner bore with a second diameter which is smaller than a first diameter of the inner bore, the inhaler having a canister (150) being adapted to move during operation between 1 and 4 mm, a drive being arranged to apply a firing force of between 15 N and 60 N of force to the canister at a position of the canister relative to a valve stem (54) at which the canister fires.
