Not similar. Space capsule and hyperbaric oxygen capsule than, the shape is a little similar, but there is a world of difference; a run around the earth in the sky, a fixed operation on the ground, the purpose and use are completely different. Space capsule launched by the rocket on top of the head, sent to Earth orbit operation, is the masterpiece of human high-tech, space capsule in addition to the pressurized cabin, with all kinds of high-tech equipment, including life support systems. Hyperbaric oxygen capsule, the use is very single, mainly used for medical and rescue purposes, such as patients with cerebral hypoxia treatment, deep-sea decompression and high-altitude hypoxia and other situations. The composition of the equipment is relatively simple, there is an oxygen device, high pressure chamber, pump pressure piping system, and control desk.
