摘要：
The invention concerns a gas mixer (1) that is adapted for providing a gas mixture to a mechanical ventilator, comprising a mixing vessel (53), a first line (10) for providing a first gas, a second line (20) for providing a second gas and a third line (30) for providing a third gas, said first, second and third lines (10, 20, 30) being in fluid communication with the mixing vessel (53) for proving said first, second and third gases to said mixing vessel (53) and obtaining a gas mixture in said mixing vessel (53), and a delivery line (60) in fluid communication with the mixing vessel (53) for recovering at least a part of the gas mixture contained in the mixing vessel (53). The first lines (10) comprises a first pressure regulator (11), a first pressure sensor (12) and a first mass flow controller (14, 15) comprising a first proportional valve (14) and a first mass flow sensor (15). The second line (20) comprises a second pressure regulator (21), a second pressure sensor (22) and a second mass flow controller (24, 25) comprising a second proportional valve (24) and a second mass flow sensor (25). The third line (30) comprises a third pressure regulator (31), a third pressure sensor (32) and a third mass flow controller (34, 35) comprising a third proportional valve (34) and a third mass flow sensor (35). The first, the second and the third lines (10, 20, 30 30) are in fluid communication with the mixing vessel (53) via an admission line (50). An oxygen sensor (51) is arranged on the admission line (50).
