A system for delivering a composition containing a nutritional supplement matrix to a user through the oral mucosa, in which the matrix is held under pressure in a canister that has a nozzle with at least one rotating internal member positioned between the canister outlet and the nozzle outlet, in which the rotating member agitates the composition to increase atomization to aid in absorption.

A system for delivery of aerosol therapy to spontaneously breathing patients comprises a housing which defines a chamber. The housing has a base, a top and a main body extending between the base and the top. An ambient air inlet is located adjacent to the base and is normally closed by an inlet valve. The housing also has a patient port for receiving a mouthpiece or a face mask. The mouthpiece has an exhaust outlet closed by an exhaust valve. Similarly, the face mask has an exhaust outlet closed by an exhaust valve. Exhaled air is exhausted through the valves and to prevent recirculation through the chamber which would adversely affect dose efficiencies. The housing also has an aerosol port for receiving a vibrating mesh aerosol generating device. The aerosol port is located in a side of the main body of the housing for delivery of aerosol into the chamber between the inlet valve and the patient port. A boss extends upwardly from the base and is spaced-apart inwardly of the main body of the housing to define a reception space or well.

A droplet delivery device includes a housing with a mouthpiece port or outlet from a nasal device for releasing fluid droplets, a fluid reservoir, and an ejector bracket having a membrane positioned between a mesh with a plurality of openings and a vibrating member that is coupled to an electronic transducer, such as an ultrasonic transducer. The transducer vibrates the vibrating member which causes the membrane to push fluid supplied by the reservoir through the mesh to generate droplets in an ejected stream released through the outlet.

A dry powder aerosol delivery device and related methods for delivering precise and repeatable dosages to a subject for pulmonary use is disclosed. The dry powder aerosol delivery device includes a housing, a cartridge, and a dry powder dispersion mechanism, and at least one differential pressure sensor. The dry powder delivery device is automatically breath actuated by the user when the differential pressure sensor senses a predetermined pressure change within housing. The dry powder aerosol delivery device is then actuated to generate a plume of particles having an average ejected particle diameter within the respirable size range, e.g., less than about 5-6 μm, so as to target the pulmonary system of the user.

A dry powder inhaler and an adherence and/or compliance monitor for use with the inhaler are provided. The inhaler has a cover which is pivotable relative to its housing in order to expose a mouthpiece. The monitor has one or more sensors. The inhaler and the monitor have formations for mounting the monitor onto the inhaler. The inhaler and monitor are designed so that when the monitor is mounted onto the housing of the inhaler and the cover is opened, the cover at least partially covers and protects the monitor.

A dry powder inhaler is provided. The inhaler is adapted for detachably mounting a compliance monitor having a pressure sensor. The inhaler has a housing comprising first and second shell parts, and a mouthpiece which defines an inhalation passage. An external surface of the housing has an orifice. A conduit from the orifice to the inhalation passage is formed by a channel in one of the shell parts and a corresponding channel cover in the other shell part. When the compliance monitor is mounted on the housing, the pressure sensor is adjacent to the orifice and is in fluid communication with the inhalation passage via the conduit.

An aerosol generating system including a housing defining an airflow outlet; a liquid aerosol-forming substrate; an aerosol generator, configured to generate an aerosol from the liquid aerosol-forming substrate; a perforated plate disposed between the aerosol generator and the airflow outlet, the perforated plate defining a plurality of apertures extending through the perforated plate; and an electrode disposed between the aerosol generator and the perforated plate, wherein the perforated plate is electrically conductive, and wherein the electrode and the perforated plate are configured to generate an electrical potential.

An aerosol generator for an aerosol dispenser is presented where, the aerosol generator has a housing having an inlet part comprising a liquid inlet configured to guide a liquid jet (L) into the housing and an air inlet configured to guide an air flow into the housing. The housing further having an outlet part having an aerosol outlet configured to guide an aerosol (C) of liquid mixed with air out of the housing. The air inlet is configured such that at least part of the air flow entering the housing through the air inlet is obstructed at a distance from the liquid jet (L) entering the housing through the liquid inlet, thereby creating a source of turbulence in the housing to interact with droplets of the liquid jet (L) to prevent coalescence of the droplets.

An inhaler article (150) includes a body extending along a longitudinal axis from a mouthpiece end (154) to a distal end (156), a capsule cavity (155) defined within the body and a capsule disposed within the capsule cavity. The capsule cavity is bounded downstream by a filter element and bounded upstream and distally by a deformable element (158) the deformable element deforms to expose an open distal end and allow the inhaler article to receive swirling or rotational inhalation airflow during consumption.

A dry powder inhaler for a capsule containing dry powder, the inhaler comprising a housing having a capsule receptacle, two actuator buttons arranged on opposing sides of the housing and two perforation needles, each needle being fixedly connected to an actuator button and movable relative to the housing towards each other from a normal position to a perforation position along an actuation direction to perforate a capsule arranged in the capsule receptacle, wherein a first end of each actuator button is connected to the housing at a lower portion of the housing and in that a second free end of each actuator button is movable into the perforation position such that the perforation needle is moved along a circular line.
