A method for performing cold atmospheric plasma treatment of respiratory infections or lung cancer having a source of a carrier gas, a cold atmospheric plasma generator connected to the source of carrier gas, a source of compressed air, a humidifier connected to the source of compressed air, a source of oxygen, a ventilator having inputs connected to an output of the humidifier and the source of oxygen, a mixer having an interior chamber formed from a dielectric, an active electrode inside the interior chamber, and an outer electrode connected to ground, wherein the mixer has a fluid input port connected to a gas output of the cold atmospheric plasma generator and an output of the ventilator, and a delivery member connected to an output of the mixer for delivering combined humidified air and cold atmospheric plasma to a respiratory system of a patient.

An apparatus to maintain an environment over an anterior surface of a patient eye can include an enclosure sized and shaped to be seated about the patient eye to form a cavity within the enclosure. The enclosure can be configured to contain a fluid other than ambient air in contact with the patient eye. The apparatus can include a fluid regulator in communication with the enclosure, where the fluid regulator can be configured to regulate the composition of the fluid contained within the enclosure.

Provided are methods for delivering psychedelic drugs to a patient in need thereof comprising administering via inhalation of a psychedelic drug in the form of an aerosol, methods for treating a central nervous system (CNS) disorder or psychological disorder via inhalation of a psychedelic drug in the form of an aerosol, devices for delivery of psychedelic drug and nitrous oxide mixtures by inhalation, including with remote activation and control, and methods for treating a central nervous system (CNS) disorder or psychological disorder via inhalation of nitrous oxide/oxygen mixtures having an amount of nitrous oxide of 15 to 25% by volume of total gas.

A first source of medical gas has a generally cylindrical male outlet with a cylindrical bore and a threaded outer cylindrical surface. A flexible cylindrical elastomeric medical gas tubing has an input end with a bushing making a flush abutment with the male outlet at the output orifice. An output end attaches to any of a plurality of medical gas utilizing devices, but preferably with a dampening disperser held in position in the space in the vicinity of a patient's nose and mouth. An annular flange of the input end bushing resides within a central cylindrical bored out region extending through the first end and nearly to the second end of a rotatable connector forming an interior surface of a connector with threads coupling with the threads of the male outlet. The second end is an annular abutment against the annular flange holding the input end tubing bushing against the outlet source and providing an airtight coupling. A gripping means is on the exterior surface of the connector.

A sensing arrangement for a medical device includes a housing having a rigid portion and a flexible portion, a collar of the flexible portion attached to an exterior of the rigid portion such that a stem of the rigid portion extends into an interior of the flexible portion. A sensing element is positioned at least partially within a passageway of the rigid portion, with at least one wire extending from the sensing element through the passageway and into the interior of the flexible portion. Front and rear flanges protrude from the flexible portion and are adapted to allow the sensing arrangement to be attached into an aperture in a wall of the medical device. The stem of the rigid portion may be positioned between the collar and front flanges of the flexible portion, such that the stem does not extend through the aperture of the wall of the medical device. There are also provided a seal, a removable component, a medical device and a system.

Systems, methods and apparatuses for vaporizing all or substantially all plant matter, liquid and/or other material to be vaporized are disclosed. Embodiments of the invention comprise a vaporization chamber sealed except for at least two conduits, heating element, a first conduit coupled to a source of fully or almost fully non-oxygenated gas, a heating element capable of heating the vaporization chamber to a temperature above a combustion temperature, a second conduit configured to transport vaporization gases and vaporized elements out of the vaporization chamber and at least one valve positioned in the second conduit preventing the flow of atmospheric air into the vaporization chamber. In some instances, the first gas substantially clears the vaporization chamber of atmospheric air prior to reaching combustion temperature. A second gas containing oxygen may be intermixed with the vaporization gases and vaporized elements proximal to the combustion chamber.

The present invention provides a device for delivering a predetermined amount of at least one substance to a body orifice of a subject; comprising: a. a container for containing said at least one substance; b. a delivery end for placement in proximity to said orifice, said delivery end being in fluid communication with said container; c. a valve mechanically connectable to said container, characterized by at least two configurations: (i) an ACTIVE CONFIGURATION in which said valve enables delivery of predetermined amount of said substance from said container to said body orifice via said delivery end; and, (ii) an INACTIVE CONFIGURATION, in which said valve prevents delivery of said predetermined amount of said substance from said container to said body orifice; d. a trigger mechanism adapted to reconfigure said valve from said INACTIVE CONFIGURATION to said ACTIVE CONFIGURATION, and vice versa; e. a fluid tight chamber.

A pulsed oxygen delivery system is disclosed for a closed breathing environment, which includes a source of gaseous oxygen, a phase dilution type oronasal dispensing mask worn by a user in a closed breathing environment defined by a pressure suit, and a pulse control module for delivering a timed and metered bolus of oxygen from the source of gaseous oxygen to the oronasal dispensing mask upon inhalation by the user.
