摘要

The mask (1) is shaped to fit over the wearer's face and form a closed air chamber over the mouth and nose, equipped with an inlet (2) and an outlet (3). An oxygen generating cartridge (4) with an inlet (5) and outlet (6) is connected to the mask by tubes (13, 14) and has two inner compartments situated on either side of a third compartment containing a sponge filter and a peroxidised material. The mask has at least one had strap (191), and a window (19) in the zone covering the wearer's eyes; its inlet and outlet are equipped with non-return valves (15, 16).
