An electrically operated aerosol-generating system may include a reservoir configured to hold a liquid aerosol-forming substrate, an atomizer assembly configured to vaporize the liquid aerosol-forming substrate to form an aerosol, and a pump configured to convey the liquid aerosol-forming substrate from the reservoir to the atomizer assembly. The reservoir may include a substantially rigid housing and an inlet valve that is configured to allow air into the reservoir based on a pressure difference between an interior of the housing and an exterior of the housing exceeding a threshold pressure difference. This improves the reliability and efficiency of delivery of liquid to the wick. The system may further include a robust reservoir that is configured to at least partially mitigate liquid leakage between the reservoir interior and the reservoir exterior.

A mask includes a body having an interior surface defining a cavity shaped to receive a user's nose. An exterior surface of the body is exposed to an ambient environment. The body includes an inlet in fluid communication with the cavity and a one-way exhaust valve in fluid communication between the cavity and the ambient environment. A therapeutic substance dispenser is in fluid communication with the cavity. In one embodiment, a nasal aromatic decongestant is disposed in the therapeutic dispenser. A mask includes an upper nasal cavity separate from a lower oral cavity, with an inlet in fluid communication with only the upper nasal cavity. A medicament delivery assembly, and methods for the use thereof, are also provided.

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.

A nebulizer device aerosolizes (or vaporizes) liquid drawn from a liquid reservoir via a fluid flow path into a nebulization chamber. An inlet port is coupled to an external air supply and leads through a check valve and Venturi nozzle (e.g. a duckbill valve) into the chamber to direct an air stream across an opening of the fluid flow path. A discharge port leads from the chamber to a user mask, mouthpiece or canula, where the aerosol or vapor mixture can be inhaled. A filtered outlet port isolates exhaled material from the external environment. Multiple discrete heating elements may be placed around the fluid flow path to preheat the liquid. If the liquid is sufficiently volatile, heating may vaporize the material which can condense back into an aerosol after mixing with the air stream. A set of check valves direct one-way fluid flow and prevent leakage or spillage of material from the device.

The invention relates to a small-volume nebulizer that is pre-filled with at least one unit-dose of medicine and hermetically sealed until use. The nebulizer may be sealed at the top with a removable cap that may be detached at the time of use and replaced with a patient connector. Likewise, the nebulizer may be sealed at the bottom with a bottom cap that is replaced with a gas source at the beginning of a therapeutic aerosol treatment.

An aerosol-generating device includes a housing having a first end defining a mouthpiece, a second end, and a cavity defined between the first end and the second end. The device also includes a reservoir within the cavity. The reservoir is configured to store a liquid aerosol-forming substrate. The device also includes an atomizer and a valve within the mouthpiece of the housing. The valve has a first side and an second side. The second side of the valve includes a hydrophilic coating, a hydrophobic coating, or both a hydrophilic coating and a hydrophobic coating.

Aerosolizing delivery apparatuses can include cartridges configured to be detachably connected to a delivery device. The cartridges can include: a housing defining a reservoir and a cartridge outlet, the cartridge outlet configured to permit fluid communication between the reservoir and an exterior of the cartridge. A surface of the housing can be configured to define a bypass port between the housing and a surface of the delivery device when the cartridge is assembled with the delivery device.

Present invention is related to a ventilator adapter and auxiliary chamber thereof. The ventilator adapter of the present invention comprises a T-shaped flow guiding adapter and an auxiliary chamber detachably connected thereto. The T-shaped flow guiding adapter contains a guiding valve that can retractably close or open its opening. The auxiliary chamber is a cylindrical hollow tubing with open ends at both sides, and a chamber partition extended into the interior of the auxiliary chamber, separating the chamber at least partially into two chambers. The present invention is able to be adapted with the conventional ventilator pipeline by using the T-shaped flow guiding adapter for connecting any suitable ventilatory medicine with the auxiliary cavity. When the ventilatory medicine is administrated, the present invention is able to guide the gas flow within the ventilator pipeline reaching into the space of the auxiliary cavity and carrying the ventilatory medicine toward the patient successfully with high amount of medicine doses for better treatment result.

A battery-operated foam inhalation device which comprises a cartridge (610) having a liquid for producing a foam and a foam outlet (654). Agitation means agitates the liquid to produce the foam, and the agitation means comprises an electric motor (762) and a battery (760) for energising the electric motor (762). A carrier (672) receives the cartridge (610) and has a carrier foam inlet (680) for fluid communication with the foam outlet (654) of the cartridge (610). A carrier foam outlet (682) dispenses the foam to a user.

A medication delivery system having a holding chamber capable of delivering dosages of medicament from a metered dose inhaler. The holding chamber includes an actuator detector, flow detector and display. In another embodiment, a medication delivery system includes a holding chamber having an input and an output end, a metered dose inhaler operably coupled to the input end of the holding chamber, and a metered dose inhaler identifier associated with the holding chamber and operable to identify the metered dose inhaler coupled to the holding chamber.
