摘要:
A method and device, for enriching a gas flow with an anesthetic, include a gas mixer (1), with gas inlets (2a, 2b) and one or more gas outlets (3a, 3b), and an anesthetic dispenser (4) connected to the one or more gas outlets. The anesthetic dispenser at least partially enriches the gas flow to provide a breathing gas flow enriched with anesthetic at a patient connector (5). A control valve (7a) is arranged fluidically in series with the anesthetic dispenser (4). The gas outlet is connected to the patient connector (5) via a gas channel (8), arranged fluidically parallel to the anesthetic dispenser (4) and in which at least another control valve (7b) is arranged. A control unit (6) actuates at least one control valve as a function of a desired value for an anesthetic concentration in the breathing gas flow to change anesthetic concentration at the patient connector (5).
