BREATHING DEVICE AS AN OXYGEN SELF-RESCUE

摘要

1. A respiratory protection device as an escape apparatus with reciprocating respiration, comprising a chemical cartridge (1) generating oxygen, a respirator bag (6) connected to the chemical cartridge (1), the chemical cartridge being secured with its inlet opening on the top end face of the respirator bag, and a respirator hose (7) with a mouthpiece (8), characterised in that a) the chemical cartridge (1) is situated inside the respirator bag (6) an wholly encased thereby, in such a way that the outer surface (A) of the chemical cartridge is surrounded on all sides by a free space within the respirator bag when the apparatus is in use, and b) the chemical cartridge (1) is received in the manner of a sheath by a thermally insulating sleeve (5) which is installed in the respirator bag at the top end face (6a) as an integral component of the respirator bag (6) and protrudes with one flange portion (5a) out of the respirator bag as well as having another flange portion (5b) arranged within the respirator bag, and connected to the latter.
