Foreign chemical oxygen self-salvage recently developed rapidly. West Germany Drǎger company produced “OXY-SR-60” type self-help device, is one of the latest. There are many new features of the instrument structure, such as the use of vacuum sealed enclosure, pharmaceutical tablets, the use of circulating gas and so on. Is now described as follows: Drǎger factory production of self-rescuer, the use of reciprocating breathing. Its advantages are simple structure, KO 2 drug utilization rate, but it has the resistance of drug resistance and suction temperature higher shortcomings. “OXY-SR-60” instrument basically
