A portable liquid oxygen (LOX) storage/delivery apparatus is provided, including an insulated LOX container having an interior, a top portion, bottom portion, and sidewall, the sidewall including a first and second side portion, both extending between the top and bottom portion, and a port system in communication with the interior for charging the container and for withdrawing LOX and gaseous oxygen. The gaseous oxygen is withdrawn from the container through a first outlet and LOX is withdrawn from the container through a second outlet when the container is positioned in a first orientation with the sidewall vertically oriented, as well as when the container is positioned in a second orientation with the second side portion oriented downwardly and with the first side portion upwardly and overlying the second side portion, and any position in between.

1. A portable liquid oxygen (LOX) storage/delivery apparatus operable in a plurality of orientations, comprising:an insulated container having an interior for containing LOX, a top portion, and a bottom portion; a first outlet in communication with the interior of said container for withdrawing gase
1. A portable liquid oxygen (LOX) storage/delivery apparatus operable in a plurality of orientations, comprising:an insulated container having an interior for containing LOX, a top portion, and a bottom portion; a first outlet in communication with the interior of said container for withdrawing gaseous oxygen, said first outlet being located adjacent to said top portion but disposed away from a center of said top portion; a second outlet in communication with the interior of said container for withdrawing LOX said second outlet being located adjacent to said bottom portion and disposed away from a center of said bottom portion, said second outlet disposed so as to be diagonally opposed to said first outlet; at least one port in communication with said interior of said container for transporting at least one of LOX and gaseous oxygen from said container; wherein gaseous oxygen can be removed from said container through said first outlet and LOX can be removed from said container through said second outlet when the portable liquid oxygen (LOX) storage/delivery apparatus is in the plurality of orientations. 2. The apparatus of claim 1, wherein said plurality of orientations includes a vertical orientation, a horizontal orientation wherein said first outlet is oriented above said second outlet, and any position there between.3. The apparatus of claim 1, wherein said first outlet is disposed maximally away from the center of said top portion.4. The apparatus of claim 1, wherein said second outlet is disposed maximally away from the center of said bottom portion.5. The apparatus of claim 1, wherein said first outlet is integrated with said top portion.6. The apparatus of claim 1, wherein said second outlet is integrated with said bottom portion.7. The apparatus of claim 1, wherein gaseous oxygen and LOX are transported through a single port.8. The apparatus of claim 1, wherein gaseous oxygen is transported through a first port and LOX is transported through a second port.9. The apparatus of claim 8, wherein said first port is substantially concentric with said second port.10. The apparatus of claim 9, wherein said second port is substantially concentric with said first port and said LOX conduit extends through said first port.11. The apparatus of claim 1, wherein said first outlet communicates with a first port, said first port being located adjacent said first outlet; and wherein said second outlet communicates with a second port, said second port being located adjacent said first port; said second outlet being connected to said second port by a LOX conduit extending through said interior of said container.12. The apparatus of claim 1, wherein said first outlet communicates with a first port, said first port being located adjacent said first outlet; and wherein said second outlet communicates with a second port, said second port being located adjacent said second outlet.13. The apparatus of claim 1, further comprising a delivery port, wherein said container is filled with LOX through said delivery port.14. The apparatus of claim 13, further comprising a LOX delivery conduit which extends from said delivery port through said interior of said container and terminating at an open end.15. The apparatus of claim 14, wherein said open end is located adjacent said top portion.16. The apparatus of claim 15, wherein said open end is centrally located in said container adjacent said top portion.17. The apparatus of claim 14, wherein said delivery port is located adjacent said bottom portion.18. The apparatus of claim 17, wherein said delivery port is disposed away from the center of said bottom portion in a similar direction as that of said first outlet.19. The apparatus of claim 1, wherein said first outlet communicates with a first port, said first port being located through said top portion and horizontally opposed from said first outlet, said first outlet being connected to said first port by a gaseous withdrawal conduit extending through said interior of said container; and wherein said second outlet communicates with a second port, said second port being located adjacent said first port; said second outlet being connected to said second port by a LOX conduit extending through said interior of said container.20. The apparatus of claim 19, wherein said second port, said second outlet, and said LOX conduit are also used to charge said container with LOX.21. The apparatus of claim 1, wherein said container is cylindrical.22. The apparatus of claim 1, wherein said apparatus delivers gaseous oxygen to the nostrils of a patient.23. The apparatus of claim 22, wherein said apparatus is configured to be carried by said patient.24. The apparatus of claim 1, wherein said container is insulated by a vacuum between said container and an outer shell wall.25. A method for allowing operation of a portable liquid oxygen (LOX) storage/delivery device in a plurality of orientations, comprising the steps of:filling a container with LOX, said container comprising a top portion and a bottom portion; withdrawing gaseous oxygen from said container through a first outlet, the first outlet in communication with an interior of said container, and said first outlet being located adjacent said top portion and above said LOX when said container is disposed in a non-vertical position; withdrawing LOX through a second outlet in communication with interior of said container, said second outlet being located adjacent said bottom portion and below said gaseous oxygen when said container is disposed in a non-vertical position, said second outlet disposed so as to be diagonally opposed to said first outlet; and delivering gaseous oxygen to a patient, wherein gaseous oxygen can be withdrawn from said container through said first outlet and LOX can be withdrawn from said container through said second outlet when the portable liquid oxygen (LOX) storage/delivery apparatus is in the plurality of orientations. 26. The method of claim 25, further comprising the step of:transporting said oxygen gas and said LOX through a port in communication with said interior of said container. 27. The method of claim 25, further comprising the steps of:transporting said oxygen gas through a first port in communication with said interior of said container; and transporting said LOX through a second port in communication with said interior of said container. 28. The method of claim 27, further comprising the step of:transporting the LOX for said filling into said container through said second port and second outlet.
