An adjustable aerosol delivery device includes an active liquid container, a carrier liquid container, a piezo disc mounted with a flexible gasket relative to the carrier liquid container, an oscillator configured to generate an ultrasonic wave that causes the piezo disc to oscillate and transmit the oscillations through the carrier liquid to the active liquid to cause at least a portion of the active liquid to become an aerosol, a bushing fixed relative to the carrier liquid container via a fixing portion that conforms to and mates with an entire perimeter of a fixing section of the bushing, and a fastener extending through the piezo disc housing and into the bushing. The fastener is configured to be loosened or tightened to manipulate a compression of the gasket to adjust a particle size of the aerosol. A pull force of the bushing is greater than a counter force of the gasket.

A dosage inhaler includes an active liquid container, which contains a liquid having an active ingredient dissolved therein, and an atomizer by which the liquid is transformed into an aerosol and can be introduced into an aerosol dome, in which there is a baffle plate and to which an inlet tube and an outlet tube are attached, and an electronic control. The atomizer can be intermittently operated by a user and the user command readout is visible to the user. The generation of the amount of aerosol inside, and below, the aerosol dome is able to be separated in time from its eventual inhalation by the user.

A smoking system includes a capillary wick for holding liquid, at least one air inlet, at least one air outlet and a chamber between the air inlet and air outlet. The air inlet, the air outlet and the chamber are arranged so as to define an air flow route from the air inlet to the air outlet via the capillary wick so as to convey aerosol formed from the liquid to the air outlet. The smoking system further includes at least one guide for channeling the air flow in the air flow route, so as to control particle size in the aerosol. The smoking system optionally includes at least one heater for heating the liquid in at least a portion of the capillary wick to form the aerosol.

A supplemental oxygen delivery system is described in which Aerosol is delivered into a housing 10, 20, which sits in the circuit from the supplemental oxygen supply and optional humidifier. The supplemental oxygen passes through this chamber 10, 20 in which the aerosol is located, and collects the aerosol transporting it to a patient via a nasal cannula 3 or a face mask 4. An aerosol generator 9 is mounted to the housing 10, 20 and delivers aerosol into an oxygen stream 13 flowing between an inlet 14 and an outlet 15 of the housing 10. The housing 10 also has a removable plug 16 in the base 17 thereof for draining any liquid that accumulates in the housing 10. There is no disruption of oxygen delivery to patients using nasal cannulas who currently have to use a separate face-mask when receiving nebulized medication.

The present invention relates to an inhaler device for delivering a dose of medicament in dry powder form from a container to a patient in need thereof. The inhaler comprises first and second airflow paths (80, 85) which are arranged such that during inhalation, a capsule (40) having a longitudinal axis and first and second end sections (90, 95) delimiting the capsule on opposing ends located in a capsule chamber (30) performs an oscillating movement in the capsule chamber parallel to its longitudinal axis between first and second sidewall portions (60, 65) of the capsule chamber.

An aerosol generating system for generating a respirable dry powder aerosol from a liquid solution or liquid suspension, having: a liquid aerosol generating nozzle having a nozzle input end designed to receive the liquid solution or liquid suspension, and having a nozzle heliox supply designed to receive nozzle heliox, the liquid aerosol generating nozzle further having a nozzle output end for outputting a liquid aerosol suspended in the nozzle heliox; and a cylindrical evaporation chamber having a cylindrical evaporation chamber input end that is connected to the nozzle output end and connected to a dilution heliox supply for receiving both the liquid aerosol suspended in the nozzle heliox and for receiving the dilution heliox, and the cylindrical evaporation chamber having a cylindrical evaporation chamber output end outputting a first intermediate dry powder aerosol at a first intermediate dry powder aerosol volume flow of a specific concentration.

A nebulizer with a press-type medicine cup is provided. The nebulizer includes a body, a medicine cup, an engagement structure, and a multi-directional resilient member. The engagement structure includes an inner protruding base and an outer protruding block disposed outside the inner protruding base. The inner protruding base and the outer protruding block extend from the body and the medicine cup. The inner protruding base includes a cavity inside and includes two through holes. The outer protruding block includes two engagement grooves. The multi-directional resilient member is installed in the cavity and includes a press element, two straight resilient arms extend from the press element, two oblique resilient arms are bent from the two straight resilient arms, and each oblique resilient arm has a block member. The two block members are inserted through the two through holes to be engaged with the two engagement grooves.

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.

A delivery device includes a toroidal shaped housing defining an interior chamber and a central open space. The housing includes an input port communicating with the interior chamber and a delivery port positioned on an inner periphery of the housing. The delivery port is in fluid communication between the interior chamber and the central open space. The delivery port is spaced from the input port, which is adapted to receive an aerosolized medicament. In another aspect, a kit includes an outer ring-like housing component and a plurality of differently configured inner ring-like housing components mateable with the outer ring-like housing to form a holding chamber. A method of delivering an inhalable substance is also provided. A mask, including mounting and sealing portions is also provided, together with a method of manufacturing such a mask. Delivery devices include various alternative adapters to be used with a mask and a substance dispenser.
