Casualty wrap with integral medical access chamber

An apparatus for providing medical treatment to a casualty including an enclosure for isolating a casualty from a contaminated environment, said enclosure having at least one substantially planar surface;

• means defining an aperture in said substantially planar surface;
• an access chamber including a flexible wall portion attached in sealing engagement to said substantially planar surface of said enclosure and positioned over said aperture;
• said access chamber including at least one vertical wall oriented substantially perpendicular to said substantially planar surface;
• means defining a first opening in said vertical wall;
• a first fastener means attached to said first opening operable for opening and closing said opening;
• a second enclosure for containing a person and means defining a second opening therein;
• second fastener means attached to said second opening, said second fastener means being compatible with said first fastener means such that as said first fastener means is operated to open said first opening, said second fastener means may become sealingly engaged with said first fastener means to place the interior of said access chamber in communication with the interior of said second enclosure;
• and
• said flexible wall portion including passage means for receiving a pressurized fluid such that when said passage means is supplied with a pressurized fluid, said access chamber moves from a collapsed position wherein said flexible wall portion is folded down upon itself to an expanded position wherein said access chamber is formed as a semi-rigid structure.

A casualty wrap for isolating a casualty from a contaminated environment, said casualty wrap comprising:

• a litter bag having at least one substantially planar horizontal elongated flexible panel;
• means defining a first elongated opening on said flexible panel with a first fastener means attached thereto and operable to open and close said first opening, said first opening being sized to receive a casualty therethrough;
• a transparent panel located at one end of said flexible panel for permitting said casualty to view out of said litter bag;
• means defining a substantially rectangular opening located approximately centrally on said flexible panel;
• an access chamber for providing access to said casualty in said litter bag for medical treatment of said casualty;
• said access chamber having four collapsible vertical walls joined at vertical edges, an upper panel having a transparent window joined to said vertical walls at horizontal edges, and an open lower portion sealed to said litter bag around the periphery of said substantially rectangular opening such that the interior of said access chamber is continuous with the interior of said litter bag;
• said horizontal and vertical edges having means defining tubular gas passages therein for receiving a pressurized gas and means for connecting said tubular gas passages to a pressurized gas source;
• and
• means defining a second elongated opening formed in one of said vertical walls with a second fastener means attached thereto operable to open and close said second opening,
• a second enclosure for containing a person and means defining a third elongated opening therein;
• third fastener means attached to said third opening, said third fastener means being compatible with said second fastener means such that as said second fastener means is operated to open said second opening, said third fastener means may become sealingly engaged with said second fastener means to place the interior of said access chamber in communication with the interior of said second enclosure;
• said vertical walls of said access chamber being collapsible to position said upper panel in a location adjacent to said lower portion of said access chamber, and said vertical walls and tubular gas passages forming a semi-rigid parallelepiped structure with said upper panel located distal from said lower portion when said tubular gas passages contain a pressurized gas.
