Patent attributes
A hyperbaric chamber includes a collapsible, pressurizable bladder and an inflatable support member supporting the bladder in a substantially uncollapsed configuration. The inflatable support member may be either internal or external to the bladder, and, in embodiments, is a rib with curvature corresponding generally to the uncollapsed shape of the bladder. A stiffening stave may provide additional support. The bladder further includes an accessway into the interior thereof and a substantially non-breathable closure on the accessway. The closure includes a substantially air-impermeable gasket sandwiched between first and second zippers. A reinforcing zipper may provide additional strength to the closure. Similarly, a reinforcing harness substantially surrounding the bladder may provide additional strength to the bladder. A source of compressed air is in fluid communication with the interior of the bladder, and a cooling source may also be provided.
