Abstract (en)
[origin: WO2005110547A2] The invention relates to secured ventilated breathing device wearable by persons in a hostile medium (1) whose atmospheric pressure Pa is substentially constant. The inventive breathing device comprises an envelop (2) consisting of a skin (3) made of a airtight material, a fluid feeding pipe (4) whose one end (5) is connectable to a fluid source under given pressure Pn which is greater than the pressure Pa and whose other end (6) passes the skin by a seal passage (7) and enters the envelop, vent means (8) embodied in the skin for connecting the inside of the envelop with the ambient medium (1) and means (10) for visually alerting the person when the fluid pressure in the feeding pipe (4) reduces under the given value threshold Ps which is less than Pn. said invention can be used, in particular for ventilated breathing devices for nuclear, bacteriological sectors, in hospital environments, etc.
