Lightweight, Collapsible Hyperbaric Chamber With Airlock

A lightweight, collapsible hyperbaric chamber/airlock system has been proposed as a portable unit for treating decompression sickness. Copies of the system could be stowed compactly and deployed when needed in settings in which decompression sickness is expected to occur occasionally but in which conventional heavy, rigid hyperbaric chambers are not available. Such settings include aviation, submarine operations, diving, and spaceflight.
