Devices and systems provide methods of controlling breathable gas generation such as for a respiratory treatment and/or for controlling ionization of the gas. In an example, a controller of a respiratory treatment apparatus controls generation of a supply of ionized air. The apparatus may include a flow generator to generate a flow of pressurized breathable gas. The flow generator may be adapted for connection with a respiratory interface. The apparatus may also include an ionizer to ionize the flow of gas. The controller may be coupled with the ionizer and the flow generator and be configured to control the ionizer to programmatically change levels of ionization of the gas. Such ionized gas treatments may be suitable for helping users to sleep or improving respiratory oxygen absorption, and may be for patients with, for example, sleep disordered breathing or chronic obstructive pulmonary disease.

A system for generating nitric oxide can include an apparatus positioned in a trachea of a mammal, the apparatus including a respiration sensor for collecting information related to one or more triggering events associated with the trachea, an oxygen sensor for collecting information related to a concentration of oxygen in a gas, and one or more pairs of electrodes for initiating a series of electric arcs to generate nitric oxide, and the system for generating nitric oxide can also include a controller for determining one or more control parameters based on the information collected by the respiration sensor and the oxygen sensor, wherein the series of electric arcs is initiated based on the control parameters determined by the controller.

A method of treating a subject suffering from, or susceptible to, a condition that can be ameliorated by inhalation of gaseous nitrite comprises the use of an apparatus comprising an activating unit that includes a photosensitiser excitable by absorption of light to excite oxygen to a singlet state, and a light source arranged to illuminate the photosensitiser. Air is caused to flow through the activating unit while the photosensitiser is illuminated by the light source, and after passing through the activating unit, is directed to the respiratory tract of the subject.

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.

An electrostatic sprayer device includes a housing, an electrostatic module inside the housing, and a reservoir having a cavity adapted to contain a fluid. A nozzle fluidly connected to the reservoir emits electro-statically charged fluid. A syringe assembly communicates with a fluid pathway that leads to the nozzle such that the nozzle can expel fluid from the syringe assembly in combination with the fluid from the reservoir.

A device and associated method for the dispensation of mists for therapeutic use, comprising: a dispensing member (2) for dispensing an air flow (3) within which micronized particles of a liquid or solid therapeutic substance are dispersed; a chamber (11) having at least one inlet (12) for said air flow (3) generated by the dispensing member (2) and at least one outlet (13) for said air flow (3) present inside the chamber (11) itself; and a communication conduit (10) interposed between said dispensing member (2) and said chamber (11) in order to introduce the air flow (3) into the chamber (11) itself; said chamber (11) being switchable between an operative condition of maximum volume in which it internally defines a space (20) for containing at least one user, and a non-operative condition of minimum volume suitable for transport and/or storage.
