Abstract: Embodiments of the present invention provide systems, methods and apparatus for to using crude neon with oxygen and nitrogen as a hyperbaric intervention breathing mixture. Embodiments include providing a work environment under pressure; performing work operations within the pressurized work environment; and providing a breathing mixture created from crude neon and oxygen as a hyperbaric intervention breathing gas. Numerous additional aspects are disclosed.

Abstract: A training device for a dry powder inhaler, includes a dry powder inhaler simulator including a housing having a bore extending therethrough, a mouthpiece connected with the housing and being in open communication with the bore; a control circuit for measuring pressure drop at the opening and displaying a single value corresponding to both inhalation rapidity and inhalation flow rate peak, the control circuit including a pressure transducer below the opening for producing an output signal corresponding to the pressure drop, an A/D converter for converting the output signal to a digitized signal; a display formed by a plurality of lighting segments, for providing an indication corresponding to both inhalation rapidity and inhalation flow rate peak, and a microprocessor connected with the display for controlling the display in response to the output signal from the pressure transducer and elapsed time.

Abstract: A powder dispenser includes a reservoir body including a supply of powder and an inhalation conduit; a driving body for rotating the reservoir body and including upper recesses and two spring fingers in lower driving recesses thereof; a rotatable metering plate for carrying a metered amount of powder from the supply to the inhalation conduit, and having an underside with ribs; a gas permeable retainer welded to the ribs; a spring biasing the metering plate toward the reservoir body; a nozzle having spiked ribs welded in the upper recesses of the driving body and including a chimney with vertical flutes; an adapter non-rotatably mounted with respect to the metering plate and including two locking recesses for receiving the spring fingers for locking engagement and two helical cam tracks with a square cross-section; a closure cap covering the driving body and including priming ribs biasing the spring fingers out of the locking recesses and engaging with the locking recesses to rotate the driving body, and two c

Abstract: A container is disclosed for storing and transporting vessels containing a liquid composition susceptible to physicochemical alteration upon changes in temperature above or below a specified temperature. It comprises an enclosure having a lower portion, a top portion and a side portion between the lower and top portions thereby defining an inner space. A lower portion of the enclosure contains a first heat sink within a base, comprising a thermal energy absorbing substance. A vial holder in the inner space holds one or more of the vessels in the inner space above the first heat sink and substantially spaced from an insulated insert inside of the enclosure. An insulating gas is contained in the inner space. A temperature indicator in the inner space indicates when the inner space has been subjected to temperatures below a predetermined level.

Abstract: A powder inhaler comprising:a powder housing for holding a supply of powdered material to be dispensed and a metering plate for holding a metered amount of said powdered material, the metering plate being alternately positionable below said supply of powdered material or within an inhalation conduit, by means of a bi-directional, angle-limited relative rotation about a common central axis;a counter for providing a visual count of the number of doses of said powdered material that have been dispensed or remain to be dispensed in response to the relative rotation, the counter including: a continuous counter ring and a coaxially mounted intermittent counter ring, both rings being mounted on a base in surrounding relation to a retaining post, being rotatable about the common central axis and having counting indicia thereon for displaying said visual count; anda display means through which at least one of the counting indicia is displayed to indicate a count corresponding to a number of doses of powdered material

Abstract: A powder dispenser includes a powder housing for holding a supply of powdered material to be dispensed, the powder housing including an inhalation conduit provided displaced relation to the powdered material supply; a metering plate including a metered dose hole for holding a metered amount of the powdered material, and positioned below the powdered material supply, the metering plate and the powder housing being relatively rotatable with respect to each other about a common central axis; a counter providing a visual count of the number of doses of the powdered material that have been dispensed or remain to be dispensed in response to the relative rotation, the counter including counter rings providing the visual count, the counter rings being rotatable about the common central axis and having indicia thereon which display the visual count, and an actuating mechanism rotatable about the central axis for incrementally rotating the counter rings in response to the relative rotation; a nozzle for breaking up agg
