Abstract
In order to keep a patient from being administered an incorrect anaesthetic, an erroneous concentration of an anaesthetic or a mixture of anaesthetics, an anaesthetic system can be equipped with a device for identifying anaesthetics in anaesthetic system. The device identifies anaesthetics by determining a parameter related to a physical property, such as density, of liquid anaesthetics. A floating body can be immersed in the anaesthetic fluid. The floating body then sinks to a depth which depends on the fluid's density. The identity of the anaesthetic can then be read off a measurement stick arranged on the floating body.
