A CPAP flow driver is adapted to split supplied breathable fluid into a first portion delivered to a venturi throat to generate a pressure drop to draw in ambient air to create a CPAP flow And a second portion that is delivered to a nebulizer to drive the nebulizer.

The invention relates to the field of inhalation devices for liquids. In particular, the invention relates to an inhalation device having improved flow characteristics. A inhalation device for medically active liquids (F) for generation of an aerosol comprises a housing (1), inside this housing (1) a reservoir (2) for storing a liquid (F), a pumping device with a hollow cylinder (9) providing a pumping chamber (3) for the generation of a pressure inside said pumping chamber (3), wherein the pumping chamber is fluidically connected with the reservoir (2) via an inlet check valve (4) which blocks in direction of the reservoir (2), a riser pipe (5) which can be received with at least one reservoir-facing, interior end (5A) in said hollow cylinder (9), and a nozzle (6) which is connected liquid-tight to an exterior end (5B) of the riser pipe (5), wherein the volume of the pumping chamber (3) is changeable by means of relative motion of the cylinder (9) to the riser pipe (5), and is characterised in that the riser pipe (5) is immobile and firmly attached to the housing (1) and to the nozzle (6), whereas the hollow cylinder (9) is moveable relative to the housing (1) and to the nozzle (6). The invention also discloses a method for the generation of an aerosol of a medically active liquid (F) by means of an inhalation device.

The spray application device with angled tip may comprise an applicator and an activator, where the applicator has a nozzle for delivery of a sprayable material. The spray application device may store a medication and may dispense the medication as an aerosol mist. The medication applicator may be adapted to dispense the medication through a nostril of a user directed at the posterior nasal cavity. The spray application device may be operable to release the medication in multiple doses of predetermined volume. The spray application device may be adapted for the user to self-administer the medication while positioned in any preferred physical position. A nozzle with a compliant nozzle shroud, an angled tip, and anatomically optimized nozzle geometry may direct the medication to a precise location within the posterior nasal cavity of a user.

An inhalation-synchronized fluid product dispenser device having a body (10) provided with a mouthpiece (400), a product reservoir (100) containing fluid product, and a dispenser mechanism (200). The device has a blocking mechanism (500; 600) for the dispenser mechanism and an inhalation-controlled trigger system having an inhalation-sensitive member (60) deformable and/or movable by inhalation, the inhalation-sensitive member co-operating with the blocking mechanism so that when deformed and/or moved, it enables the dispenser mechanism to be actuated. The device has a protective element (1) the trigger system, the protective element disposed between the mouthpiece and the inhalation-sensitive member and made of a porous material that allows air to pass through it but blocks the passage of water, dust and foreign bodies.

The present invention relates to dose counting mechanisms for medicament inhaler devices, for example metered-dose inhaler (MDI) devices. In particular, the invention relates to a counter comprising a counting component (20,620), a locking element (46,646) for resisting movement of the counting component (20,620), and a distinct driving element (70,670) for driving movement of the counting component (20,620). The locking and driving elements are actuated by movement of a common element to move the locking element (46,646) out of engagement with the counting component (20,620) and to move the driving element (70,670). The driving element (70,670) applies a motive force to the counting component (20,620) before the locking element (46,646) fully disengages from the counting component (20,620).

An apparatus and method are provided for administering an inhaled drug to a person while simultaneously administering oxygen from a medical oxygen mask. The inhaled drug is from a pressurized metered dose inhaler (MDI), employing an extender tube about 3-10 cm long that fits into or over the mouthpiece of the inhaler. The MDI with extender tube is inserted into the mask and positioned so that the plume of drug travels through the extender when the MDI is actuated and is directed to just inside the mouth of the person. In an embodiment, an exhalation filter is provided to prevent contamination from infectious agents in the exhaled air from the person.

A capsule for a heat-not-burn (HNB) aerosol-generating device may include a first heater, a second heater, and a frame sandwiched between the first heater and the second heater, and a cannabinoid-containing material. The frame may define open spaces therein and have a rigidity that is adequate to support the first heater and the second heater. The open spaces within the frame may be interconnected and sized for aerosol-permeability and capillary action.

A opioid overdose treatment assembly for treating an opioid overdose includes a housing that can be worn on a user. An inhaler is coupled to the housing and the inhaler contains an aerosolized medication for treating an opioid overdose. The inhaler is actuatable to release a pre-determined amount of the aerosolized medication for inhalation by the user when the user is suffering from an opioid overdose. A communicator is coupled to the housing and the communicator is in wireless communication with a communication network. In this way the communicator can be placed in communication with emergency responders.

An inhaler including a housing having a chamber to receive a valved canister and a stem block, and a mouthpiece in fluid communication with a passage of the stem block; and an actuation mechanism including configured to engage an outer surface of the stem block at a predefined angle relative to the longitudinal axis of the stem block to cause the downward movement of the stem block to activate the valve and release the aerosolizable liquid as the dose of the aerosolized spray out of the mouthpiece of the mechanical inhaler.

A power supply unit of an aerosol generating device includes: an accommodating portion with a bottom and cylindrical shape, which is configured to accommodate a columnar cartridge that stores an aerosol source in a state in which the cartridge is rotatable 360 degrees in a circumferential direction of the cartridge. A rotation suppressing portion configured to generate a frictional force between the cartridge and the rotation preventing portion so as to suppress rotation of the cartridge in the circumferential direction is provided on a bottom portion of the accommodating portion.
