To avoid the release of gas from more than one of the units (8, 9, 10) at a time, a cross-shaped device is fixed on top of the apparatus (1). The anaesthesia apparatus (1) has at least two individual vapor supply units (8, 9, 10) for the adjustment of the gas concentration. To avoid the release of gas from more than one of the units (8, 9, 10) at a time, a cross-shaped device is fixed on top of the apparatus (1) containing a mechanical working lock (31, 32, 33, 34, 35, 36) for each of the supply units, which closes a valve (25, 26, 27) positioned inside a duct when another lock (31, 32, 33, 34) is opened. |
