A vapor delivery device having a reservoir for containing an amount of fluid. An ejector receives the fluid, and a controller fires the ejector to express a given dosage of the fluid through a number of nozzles in the ejector into an airstream at a firing frequency and for a firing duration. As the amount of the fluid within the reservoir decreases, the controller also at least one of reduces the firing frequency of the ejector, increases the number of nozzles, and increases the firing duration.

An aerosol preparation assembly includes an entrainment chamber defining an entrainment volume. The entrainment chamber includes a gas inlet port, an aerosol inlet port and an outlet port. The entrainment chamber is configured such that a velocity of a flow of a gas within the entrainment volume is less than a velocity of the flow of the gas within the gas inlet port. The entrainment chamber is configured such that at least a portion of inlet aerosol is entrained into the flow of the gas within the entrainment volume to produce an entrained aerosol flow at the outlet port. The particle selection chamber is configured to receive the entrained aerosol flow and produce an outlet aerosol flow. The particle selection chamber and nozzle are collectively configured such that a volumetric median diameter of the outlet aerosol flow is less than a volumetric median diameter of the inlet aerosol.

Methods are provided for the treatment of RSV infections in young children. More specifically, methods are provided wherein polypeptides that bind F protein of hRSV and that neutralize RSV infection are administered to the lungs of young children at specific dose regimens.

The present disclosure relates to aerosol delivery devices. The aerosol delivery devices include mechanisms configured to deliver an aerosol precursor composition from a reservoir to an atomizer including a vaporization heating element to produce a vapor. For example, a bubble jet head may be configured to dispense the aerosol precursor composition to the atomizer. The bubble jet head may be fixedly coupled to the atomizer. The bubble jet head may include a precursor inlet, an ejection heating element, and a precursor nozzle. The atomizer may include a vaporization heating element.

The invention relates to a vaporiser head for an inhaler, in particular for an electronic cigarette product, comprising a heating element-wick structure assembly consisting of an electrically operable heating element, which has at least one liquid-conducting through-channel and a porous and/or capillary wick structure arranged at an inlet side of the heating element, and a support plate for retaining the heating element-wick structure assembly. The vaporiser head has a liquid-conducting cannula having a preferably protruding piercing region.

A heater for a vaporization device includes a fluid reservoir and a porous and permeable heating element made of an electrically conductive material and located within the reservoir. The reservoir and the heating element located within the reservoir define a fluid volume sufficient to capture and retain a fixed volume of fluid ejected from an ejection head in the vaporization device. Application of electrical energy to the heating element vaporizes the fixed volume of fluid in a fixed amount of time.

An apparatus for a fluidic ejection device and a fluidic ejection device containing the apparatus. The apparatus includes a pivot member having at least a first position and a second position, a shaft attached on a first end thereof to the pivot member and on a second end distal from the first end to a capping structure, wherein pivot of the pivot member pivots the capping structure from a first capped position to a second uncapped position adjacent an ejection head of the fluidic ejection device.

An inhalation device, assembly or system can include a kit and a pharmaceutical composition. The device can be adapted for administering therapeutic aerosols to pediatric patients, including neonates, infants or toddlers. The device can further include a vibrating mesh aerosol generator that can be insertable into a flow channel of the inhalation device through a lateral opening, and a valved face mask. The device can be connectable to a gas source through which a gas, such as oxygen, can be received into the flow channel at a low flow rate.

A pharmaceutical drug delivery device and method of preventing drying out and drooling of an ejection head for the drug delivery device. The device includes a drug delivery device body; a fluid outlet nozzle attached to the drug delivery device body; and a fluid jet ejection cartridge containing a liquid pharmaceutical drug disposed in the drug delivery device body. A fluid ejection head is attached to the fluid jet ejection cartridge and the fluid ejection head is in fluid flow communication with the fluid outlet nozzle. An elongate, serpentine air flow path is provided between and outer surface of the fluid jet ejection cartridge and an inner surface of the fluid outlet nozzle. The elongate, serpentine air flow path provides a reduced pressure differential adjacent to a surface of the fluid ejection head upon use of the drug delivery device and provides a humidification zone.

An automatic medicine exchange and atomization device includes a breathing tube, a main control module, an atomization module and a plurality of medicine solution containers. The breathing tube communicates with a patient's respiratory tract. At least one medicine solution container, each containing a corresponding medicinal liquid, communicates with the breathing tube, and is connected to the atomization module. The atomization module is electrically connected to the main control module, which controls the atomization module to atomize a solution in a selected one of the container, so that the atomized medicine solution enters the breathing tube. As the main control module controls, according to the needs of different experiments in different stages, the atomization module to atomize the medicine solution in the specific medicine solution container, thus requiring no manual replacement, and being convenient and fast.
