Abstract: An air purification device with air guidance, including a housing, including an air intake region, formed in an inlet plenum, for drawing dirty air into the housing, and an air discharge region, formed in an outlet plenum, for discharging filtered air from the housing, a fan impeller of a radial ventilator that is rotatable about a ventilator rotational axis and an air filter for filtering the air drawn in through the air intake region being situated in the housing, the main nozzle air flow formed downstream from the air filter being deflected in the direction of the fan impeller at a main nozzle situated in the housing, upstream from the fan impeller. The main nozzle air flow is split by an auxiliary nozzle that is situated upstream from the main nozzle, and the auxiliary nozzle supplies an auxiliary nozzle air flow into the inner intake region of the fan impeller.

Abstract: A filling system for an anesthetic dispenser has a coding feature. An opening (29) is provided at a connection piece top side (10) of an outlet connection piece (8) of a bottle adapter (100). The opening (29) is connected to the lateral slots (9) and a length of rods on an inner wall of the filling connection piece is dimensioned such that they mesh both with the slots (9) and with the opening (29).

Abstract: A monitoring process for the reliable metering of different gaseous anesthetics uses a gaseous anesthetic monitor designed as only a single-channel monitor for determining the concentration of only one gaseous anesthetic. The process also uses an associated gaseous anesthetic metering means.
