Abstract
A life support system has a semi-closed rebreather supplying oxygen for multiple users, such as high altitude parachutists. A first tank supplies oxygen to initially purge the system, and a second, larger tank supplies oxygen at prescribed amounts for the duration of a mission. Users are connected by hoses to an inlet hose manifold on a scrubber body of the rebreather. The inlet hose manifold has an inlet port boss to receive exhaled gas from each user and an overpressure valve vents excessive amounts of exhaled gas. A CO absorbent in the scrubber body scrubs CO from the exhaled gas. An outlet hose manifold is connected to the scrubber body and has an inlet fitting to supply oxygen and at least one outlet port boss to feed the oxygen and the CO scrubbed gas to the users. This reliable system is lighter-weight and smaller than contemporary systems.
