The invention provides an inhalation device system for the in-halative administration of a medically active liquid in nebulized form, the system comprising an inhalation device and an exchangeable reservoir for holding the medically active liquid, wherein the inhalation device comprises - a housing having a receiving unit, the receiving unit having a connection unit adapted to releasably and fluidically connect to a connection port of the exchangeable reservoir, the receiving unit being adapted to receive and fluidically connect to the exchangeable reservoir; - a nozzle for nebulization of the medically active liquid; and - a pumping unit arranged within the housing and adapted to be fluidically connected to the reservoir (via the connection unit of the receiving unit) and to the nozzle and being adapted to convey (pressurize, pump) the medically active liquid in a downstream direction from the reservoir to the nozzle.

A medication inhalation apparatus preferably formed of a single, unitary sheet of stock, includes an outer housing, movable between collapsed and expanded states, encompassing a first volume. An inner housing within the outer housing encompasses an inner or second volume. An inhaler opening to the first volume is within a wall of the outer housing at a first location. A mouth opening to the inner volume is within a wall of the outer housing and the inner housing at a second location. A one-way inhalation valve connecting the first volume and the inner volume is within a wall of the inner housing. A one-way exhalation valve connecting the inner volume and the exterior of the outer housing is within a wall of the outer housing and inner housing at a third location. The valve preferably includes an elongated spring body formed of a semi-pliant material with a strength and rigidity providing limited flexibility. A first separation is perpendicular to the elongate axis of the spring body, and extends from a first edge of the spring body across at least a portion of a width of the spring body. A second separation perpendicular to the elongate axis of the spring body extends from a second edge of the spring body across at least a portion of the width of the spring body.

Provided is a Dry Powder Inhaler (DPI) arrangement comprising a DPI arranged in fluid communication with a spacer device (110) comprising a bag (112) and a body (118) including inlet (114) and opposed outlet (116), the inlet (114) and opposed outlet (116) being provided on, and integral with, the body (118). The body (118) and bag (112) combine to form chamber (120) for operatively receiving vaporised dry powder medication. The inlet (114) and outlet (116) each are in the form of a port that is in fluid flow communication with the chamber (120). The inlet (114) and outlet (116) define, and are separated by, a broad V-formation formed as part of the body (118). The body (118) further includes an elliptical lower perimeter (118.1) defining flange (118.2), for demountably receiving bag (112).

Methods and devices for delivering a dose, such as a medicament, for inhalation. A dose may be stored by a delivery device and dispersed and delivered in a metered fashion to a subject, such as by the subject inhaling via a mouthpiece of the delivery device. One or more chambers of the device may have a toroidal shape and may be arranged to be selectively opened for fluid communication with a flow path of the delivery device, such as by sliding the chamber relative to a portion of the flow path. The flow path may include a restriction that permits air to bypass the chamber, and/or the chamber may be arranged so that fluid entering the chamber interacts with fluid exiting the chamber so as to enhance dispersion of the dose.

The invention relates to a valveless spacer device for a metered dose inhaler (MDI), the spacer device comprising a body having an inlet and an outlet opposed from the inlet, a demountable, flexible bag attached to the body, the bag and body together defining a chamber, such that the inlet and outlet are in fluid flow communication with an interior of the chamber, wherein the inlet is configured to be connected to an MDI containing a drug to be inhaled and wherein the flexible bag, following actuation of the MDI, serves as a reservoir allowing for the formation of a cloud or mist of the drug therewithin which is then ready for inhalation, the flexible bag being configured to be at least partially deflatable and at least partially inflatable commensurate with a single breath and/or rebreathing.

A stable-foam inhalation-device cartridge for a stable-foam inhalation device which dispenses a stable foam to be consumed by a user. The cartridge is devoid of an electrical energisation component. The cartridge includes a flexible mixing chamber, first and second foam-generation elements, an expansion chamber, a partitioning element having one or more mixing members for agitating a consumable foam and a discharge element. The discharge element has an outlet opening an inlet opening and a discharge conduit which interconnects the inlet opening with the outlet opening. The discharge conduit has a longitudinal extent which locates the inlet opening at a position closer to the partitioning element than to the outlet opening.

Systems, methods and apparatuses for vaporizing all or substantially all plant matter, liquid and/or other material to be vaporized are disclosed. Embodiments of the invention comprise a vaporization chamber sealed except for at least two conduits, heating element, a first conduit coupled to a source of fully or almost fully non-oxygenated gas, a heating element capable of heating the vaporization chamber to a temperature above a combustion temperature, a second conduit configured to transport vaporization gases and vaporized elements out of the vaporization chamber and at least one valve positioned in the second conduit preventing the flow of atmospheric air into the vaporization chamber. In some instances, the first gas substantially clears the vaporization chamber of atmospheric air prior to reaching combustion temperature. A second gas containing oxygen may be intermixed with the vaporization gases and vaporized elements proximal to the combustion chamber.

A device, called expandable spacer, for improving the efficacy of drug delivery in metered dose inhalers is described. The device has a body made of flexible (might be expandable) material. It can shrink in size when it is not in use and can go back to its normal shape and size when it is used. The device further comprises a valve (can be one way valve) that helps the drug to be maintained inside the spacer's cavity and opens during inhalation and closes during exhalation.
