Abstract:
A body mountable system for mixed gas storage and delivery comprising:containment means for containing mixed gas received at cryogenic temperature and in an amount so that the mixed gas is initially at a pressure sufficient to maintain the mixed gas in a single phase, said containment means having a volume of 4.2 liters or less for each 60 minute supply of mixed gas deliverable by the system;outlet means connected with said containment means for selective expulsion of the mixed gas from said containment means therethrough;passive heat exchange means connected with said outlet means to receive the expelled mixed gas at said outlet means and conduct the expelled mixed gas to a connection, said heat exchange means being routed for introducing heat into said containment means at a rate determined by a rate of expulsion of the mixed gas from said containment means through said outlet means to thereby maintain sufficient energy to expel the mixed gas remaining in said containment means from said containment means and so that the mixed gas remaining in said containment means remains in the single phase; anda body mountable unit including a pack structure configured for releasably receiving said containment means, said outlet means and said passive heat exchange means therein, said unit including conditioning means for conditioning the mixed gas by raising temperature of the mixed gas to a usable temperature, said conditioning means integrally maintained in said pack structure and connectable with said connection of said passive heat exchange means when said containment means, said outlet means and said passive heat exchange means are mounted in said pack structure.
