A device for removing at least laughing gas and anesthetic vapor from a gas sample based on a molecular sieve shall be improved such that it possesses good adsorption properties for both gas components. A molecular sieve arrangement is provided, which is flown through from a gas inlet to a gas outlet and comprises a first molecular sieve area with a first pore size between about 0.3 nm and 0.5 nm and a second molecular sieve area with a second pore size between about 0.8 nm and 1 nm.

Device for absorbing a gas mixture consisting of laughing gas and

A safety filling device for filling a liquid anesthetic into a reservoir of an anesthetic-metering device with a receiving device, which has an inlet opening for a coupling piece or a closing piece. An essentially rigid guide lever is provided in the connection area between the receiving device and the closing piece. A hinge connection is provided which makes possible an axial displaceability of the guide lever within the inlet opening and a rotary movement of the guide lever outside the inlet opening.

Safety filling device for anesthetic evaporators

A device for mixing anesthetic vapor with a gas according to the bypass principle such that anesthetic gas or liquid anesthetic is prevented from escaping from the evaporator chamber during transportation. The switching on of the anesthetic evaporator takes place under defined pressure conditions in the evaporator chamber. A transport position, which precedes the switch-off position, and in which a ventilating valve of a ventilating line arriving from the evaporator chamber is switched into the switch-off position by the setting member, is provided on the setting member.
