Transportable hyperbaric life support chamber

A transportable hyperbaric life support chamber, comprising:

• a transportable hyperbaric chamber which is generally cylindrical in configuration having a first end, an opposite second end and being of sufficient width and length to receive an injured person, said chamber having a manway opening at said first end being of sufficient diameter to receive an injured person;
• chamber interconnection means at said first end of said transportable hyperbaric chamber for temporarily connecting said manway opening of said transportable hyperbaric chamber first to a manway opening of a deck chamber so that an injured person can be transferred from such deck chamber through said manway opening to said transportable hyperbaric chamber and subsequently to a manway opening of a hospital chamber so that such injured person can be transferred out of said transportable hyperbaric chamber to said hospital chamber;
• a chamber support platform including means for mounting said transportable hyperbaric chamber thereon and for supporting said manway opening of said transportable hyperbaric chamber in an aligned position with respect to the manway openings of said deck chamber and said hospital chamber;
• a pressure safe chamber door and means mounting said pressure safe door for movement between a closed position in a sealed connection over said transportable chamber manway opening and an open position fully out of said manway opening so that an injured person can be transferred therethrough;
• a stretcher support assembly mounted in said transportable chamber and extension mounting means for moving said stretcher support assembly from a retracted position in said transportable chamber to an extended position in which said stretcher support assembly extends through said manway opening and into said deck or hospital chamber for transferring a patient when said transportable chamber and deck or hospital chamber are temporarily connected;
• said transportable chamber having at said first end a wall end section transversely directed with respect to the longitudinal axis of said transportable chamber and having said manway opening formed therein;
• said pressure safe door having a configuration and size larger than said manway opening, a door arm connected to said pressure safe door;
• and being positioned inside of said chamber and said transverse wall section, said pressure safe door having a peripheral outside surface portion having a sealing member mounted in said surface for sealingly engaging the inside of said transversely directed chamber wall end section with said door in a closed position;
• first and second pivot mounting means mounted with said transverse wall end section and with said door and being interrelated to move said door from a closed position in which said door is transversely positioned with respect to the longitudinal axis of said chamber;
• and is sealed against said chamber transverse wall end section to an open position in which said door is pivoted to a position out of the path through said manway opening with said door being parallelly oriented with respect to the longitudinal axis of said chamber;
• said first pivot means being attached to said door arm and to said transverse wall end section of said transportable chamber mounting said door arm for pivotal movement between a first position in which said door arm is positioned transversely to the longitudinal axis of said chamber and a second position in which said door arm is positioned approximately parallel with respect to the longitudinal axis of said chamber;
• said second pivot means attached to said pressure safe door and to said door arm mounting said pressure safe door for pivotal movement with respect to said door arm;
• a lockable link and link mount means mounting said lockable link on said transverse wall section for pivotal movement;
• removable link set means for setting said link in a transversely extending position in which a portion of said link extends into the path of said manway opening, said lockable link being movable to a withdrawn position out of the path of said manway opening when said link set means is removed;
• a matching latch element mounted on said pressure door;
• and
• a lock handle assembly mounted onto said lockable link for pivotal movement with respect to said link, said lock handle assembly including latch means extending longitudinally into said manway opening in said transverse chamber wall section and into locking engagement with said mating latch element mounted on said pressure safe door.
