A pneumatic nebulizer that produces a high volume of aerosols for inhalent delivery of medications and other constituencies. High pressure gas formed into a gas jet is passed through a thin choked region of fluid that is entrailed and impinged upon an aerosol amplifier which creates a spray whose aerosol components are directed up through vents to an aerosol outlet for delivery. Larger-sized liquid particles are caused to pool up in a region surrounding the aerosol amplifer and then drip down back into the liquid medication reservoir.

A vented vial adapter for reconstitution of a medicament in a vial includes a vent lumen and a medicament lumen. The vent lumen has a cross-sectional area equal to or greater than that of the medicament lumen so that the fluid flow rate through the vent lumen is equal to or greater than that of the medicament lumen. As a result aerosols of the medicament outside the adapter are avoided as is the withdrawal of air bubbles from the vial as the reconstituted medicament is withdrawn from the vial. To maintain the diameter of the sharpened cannula of the vial adapter as small as possible, the vent lumen includes a concave wall facing the medicament lumen and a convex outer wall. In one embodiment, the vent lumen is in the shape of a polygon.

The present invention provides a foamable composition for administration to the skin, body surface, body cavity or mucosal surface, e.g., the mucosa of the nose, mouth, eye, ear, respiratory system, vagina or rectum.

Electrocatalyst powders and methods for producing electrocatalyst powders, such as carbon composite electrocatalyst powders. The powders have a well-controlled microstructure and morphology. The method includes forming the particles from an aerosol of precursors by heating the aerosol to a relatively low temperature, such as not greater than about 400° C.

A method and system is disclosed which is capable of delivering at a high dose rate, respirable solid aerosols derived from aqueous- or nonaqueous-based solutions containing the desired therapeutic agent(s). The method and system comprises the integration of an aerosol generator, an aerosol evaporator, an aerosol concentrator, and an aerosol flow regulator. The aerosol generator generates 10-30 μm droplets, with a narrow size distribution. The aerosol jet is arrested by a coaxial counter-flow heated air jet, and evaporated rapidly by annular swirling heated air. Most of the air, together with the unwanted solvent vapor, is removed from the aerosol stream during the process of aerosol concentration. The output aerosol carries the dry particles to be inhaled by the patient. The respiratory-governed control of aerosol fluid generation system delivers fluid containing the test agent of interest (drug or toxin) to the aerosol generator throughout inhalation.

Aerosol formulations suitable for use in pressurised metered dose inhalers comprise a hydrofluoroalkane propellant, an medicament for inhalation and a surfactant which is a a C₈–C₁₆ fatty acid or salt thereof, a bile salt, a phospholipid, or an alkyl saccharide.

A non-burning type flavor inhaler includes an aerosol source that generates an aerosol; an atomizer that atomizes the aerosol source without burning; a power source that supplies power to the atomizer; a light-emitting element; and a control unit that controls the light-emitting element. The control unit controls the light-emitting element in a first light-emitting mode in a puff state inhaling the aerosol, and controls the light-emitting element in a second light-emitting mode different from the first light-emitting mode in a non-puff state not inhaling the aerosol. The second light-emitting mode changes according to a number of puff actions for inhaling the aerosol.

An aerosol solution composition for use in an aerosol inhaler comprises an active material, a propellant containing a hydrofluoroalkane, a cosolvent and optionally a low volatility component to increase the mass median aerodynamic diameter (MMAD) of the aerosol particles on actuation of the inhaler. The composition is stabilized by using a small amount of mineral acid and a suitable can having part or all of its internal metallic surfaces made of stainless steel, anodized aluminium or lined with an inert organic coating.

A continuous high-frequency oscillation breathing device delivers therapy during both inhalation and exhalation in order to assist in clearing secretions from the lungs. A fixed shrouded-venturi patient interface circuit is combined with medicated aerosol to deliver continuous high-frequency oscillation therapy. Fixed open apertures in the patient interface circuit allow ingress and egress of flow, and are calibrated to allow exhalation and prevent stacking of successive breaths.

An aerosol generator includes a flow passage having an inlet end, an outlet end, and a constriction in the flow passage at the outlet end. A heater is operable to heat liquid in the flow passage to produce a vapor, which is expelled from the outlet end of the flow passage.

Systems and methods are provided for aerosolizing a pharmaceutical formulation. According to one method, respiratory gases are prevented from flowing to the lungs when attempting to inhale. Then, respiratory gases are abruptly permitted to flow to the lungs. The flow of respiratory gases may then be used to extract a pharmaceutical formulation from a receptacle and to place the pharmaceutical formulation within the flow of respiratory gases to form an aerosol.

Nanotube films and articles and methods of making the same are disclosed. A conductive article includes an aggregate of nanotube segments in which the nanotube segments contact other nanotube segments to define a plurality of conductive pathways along the article. The nanotube segments may be single walled carbon nanotubes, or multi-walled carbon nanotubes. The various segments may have different lengths and may include segments having a length shorter than the length of the article. The articles so formed may be disposed on substrates, and may form an electrical network of nanotubes within the article itself. Conductive articles may be made on a substrate by forming a nanotube fabric on the substrate, and defining a pattern within the fabric in which the pattern corresponds to the conductive article. The nanotube fabric may be formed by growing the nanotube fabric on the substrate using a catalyst, for example, in which the catalyst is a gas phase catalyst, or in which the catalyst is a metallic gas phase catalyst. The nanotube fabric may be formed by depositing a solution of suspended nanotubes on the substrate. The deposited solution may be spun to create a spin-coating of the solution. The solution may be deposited by dipping the substrate into the solution. The nanotube fabric is formed by spraying an aerosol having nanotubes onto a surface of the substrate.
