Abstract: A deployable fairing for a transport vehicle comprises a flexible, internally pressurizable enclosure supported by a structural frame. The structural frame comprises a plurality of rigid structural members forming at least two subframes that are pivotally coupled to one another and is foldably movable between a collapsed configuration and an expanded configuration. The enclosure moves with the structural frame, unfolds when the structural frame moves into the expanded configuration and folds in upon itself when the structural frame moves into the collapsed configuration. Moving the structural frame into the expanded configuration develops tension on at least part of the outer surface of the enclosure, and movement of the structural frame into the collapsed configuration releases the tension. When the enclosure is internally pressurized while the structural frame is in the expanded configuration, the outer surface of the enclosure is structurally stiff and conforms to a predefined aerodynamic shape.

Abstract: A dilution spacer for a metered-dose inhaler comprises an enclosure defining a dilution chamber. An ambient air inlet and an outlet are in fluid communication with the dilution chamber. The ambient air inlet is positioned opposite the outlet whereby suction through the outlet from outside the enclosure draws ambient air into the enclosure through the ambient air inlet to generate an airflow path from the ambient air inlet through the dilution chamber and out of the outlet. The dilution spacer may include an actuator inlet configured to securely releasably interengage a metered-dose inhaler actuator mouthpiece, or may include a receptacle having an actuator nozzle and configured to receive a metered-dose inhaler canister, A metered-dose inhaler plume entering the dilution chamber intersects the airflow path thereto and airflow along the airflow path entrains and redirects at least a portion of the metered-dose inhaler plume toward the outlet.

Abstract: A medical aerosol delivery device comprises a housing having a first opening and a second opening and defining a fluid passage between the first and second openings. The housing comprising a pressurized medical aerosol canister actuator having a canister receptacle disposed within the fluid passage and having a valve chamber comprising a fine bore nozzle positioned to direct atomized medicament toward the first opening. The fluid passage includes an annular portion bypassing the canister receptacle and the housing comprises a movable closure member for selectively obstructing the fluid passage.

Abstract: A flexible bag aerosol holding chamber is sealed around the outlet passage of the actuator for a pressurized metered-dose inhaler. An elastic-loaded mouthpiece is sealed around the inlet passage of the actuator so that the user may intermittently break the seal around the inlet passage by withdrawing the mouthpiece, thus allowing inhalation of a portion of the aerosol contents of the chamber. In a preferred embodiment of the invention, the aerosol contains a compound which has traditionally been smoked such as nicotine or a cannabinoid. The user may draw upon the chamber's contents a number of times at a frequency analogous to smoking until the chamber is fully collapsed. One inhaler actuation, and one filled chamber, are comparable to one cigarette. The collapsible bag chamber allows for economy of inhaler actuations relative to user inhalations, without the aerosol being diluted by ambient air.
