Abstract (en)
[origin: US2005115560A1] In a compressed air breathing apparatus, a single combined high/medium-pressure line ( 8 ) consisting of a medium-pressure hose and a coaxial, flexible high-pressure line inside said hose is integrated into the pressure reducer ( 5 ) connected to a compressed air bottle so that said line can rotate in axial direction. The free end of the combined high/medium-pressure line ( 8 ) can also rotate in axial direction when connected to a manifold block ( 9 ) for distributing the supplied high or medium-pressure air to connections for a lung machine ( 11 ), a pressure gauge ( 15 ), and an alarm whistle ( 17 ) that is controlled at high pressure and operated at medium pressure. The manifold block ( 9 ) is equipped with an additional high-pressure fast-fill connection ( 14 ) and an additional medium-pressure connection ( 13 ). A compressed air breathing apparatus of this design is simple, convenient, and safe to handle.
