摘要

The invention relates to a device in order to mix or co-infuse of the gases in 2002. / p & & p & the device comprises a tube 1 closes off by a ball 2 freely movable in the tube. The tube comprises two entrees of the gas 3 and 4 between which can move the ball 1. In a generatrice of the tube, the wall that - latter is provided with a series of orifices 5 and the assembly of these orifices is connected to a common output 6. The wall of the conduit comprises a complementary orifice 7 is connected by a gas duct 8 is a flow sensor 9 which controls an alarm 11. / p & & p & application is the detection of the approach of a critical value of the ratio of debits of the breathable gas forming a mixture.
