Abstract
Abstract To a gas mask (1) is connected an inspiration and suction device consisting of an evacuation hose (6), an oxygen hose (7) and a suction hose (8). The evacuation hose (6) is connected to the oxygen mask's connecting piece (4) for open communication with the oxygen mask's interior. The oxygen hose (7) is in open communication with the oxygen mask's interior and runs from an oxygen gas supply. One end of the suction hose (8), which hose evacuates the exhaled air, is in open communication with the evacuation hose's (6) interior and located at a suitable distance from the oxygen mask's (1) connecting piece (4), while the other end is connected to an evacuation system.
