Abstract:
1. A mass oxygen distribution system (MODS) for mass delivery and distribution for of breathing oxygen, the system comprising: a MODS mobile unit for storing a large amount of liquid breathing oxygen (LOX), meaning about at least 75 L of LOX, within an enclosure of the MODS mobile unit for controlling the distribution of oxygen from said enclosure at safe pressure for being mass-distributed to one or more end users; A LOX on board oxygen source within said enclosure having at least one pressurized vessel in which a relatively large amount of oxygen, meaning about at least 75 L of LOX, is maintained in a liquid state (LOX) in readiness for being volatilized to provide oxygen in vapor form for many hours of said distribution; the enclosure being supported by wheeled support members for allowing the enclosure to be moved to and through premises where mass distribution to said one or more end users is required; the enclosure being substantial in size but precisely dimensioned for being capable of fitting easily though passageways and doorways of a wide range of premises where mass distribution could be required; a fill port of the enclosure for filling of the LOX converter; a fill valve communicating with the fill port and in communication with the oxygen converter for providing oxygen from a main source thereof to the oxygen converter to provide LOX to the pressurized vessel for distribution by the mobile unit, a fluid line providing liquid oxygen from the pressurized vessel to be changed to vapor form; vaporizer array provision within the enclosure for converting the liquid oxygen to cold gaseous breathing oxygen; heat exchanger provision within the enclosure for warming the cold gaseous breathing oxygen to safe breathing temperature; dual input ports of said enclosure adapted for receiving oxygen alternately from external auxiliary oxygen sources such as VGL (variable gas/liquid) storage, whereby said system is capable of supplying breathing oxygen at controlled high flow rates and at controlled temperature and pressure for an extended period of time by use of either on board oxygen storage or external oxygen sources; the vaporizer provision comprising dual independent sets of vaporizers that allows an operator of the system to switch between said external auxiliary oxygen sources, with use of one of the sets of vaporizers for each auxiliary oxygen source; said system permitting filling/refilling of the on board LOX source when receiving oxygen from external auxiliary oxygen source such as VGL source, while at the same time supplying continuous breathing oxygen output to patients.
