A control system controls fresh gas dispensing for an anesthesia device, with a patient gas-measuring unit, an anesthetic-dispensing unit, a user interface, and a fresh gas regulation unit. With a transition from deactivated assistance mode to activated assistance mode, a processing unit receives a measured signal, a fresh gas signal and an assistance signal and calculates an end tidal anesthetic concentration over time based on a current volume flow, a predefined volume flow and on a current end tidal anesthetic concentration and stores this as a preset curve. A fresh gas correction signal is output upon the determined current end tidal anesthetic concentration leaving a surrounding range of the preset curve. A predefined volume flow curve is changed as a function of the correction signal. The volume flow of fed fresh gas is increased when the surrounding range is undershot and is reduced when the surrounding range is exceeded.

Control system and process for controlling the dispensing of fresh gas for an anesthesia device

A measuring apparatus (), for the contactless determination of a temperature (T) of an object (), e.g., of a human, has an infrared camera () with a focus (). A calibrating device () is connected to the infrared camera () via a data link. The calibrating device () has an outer shell () with an emissivity on the outside similar to that of the object (). A temperature sensor () is arranged in the outer shell (). Moreover, a method for contactless determination of a temperature (T) of an object () with the measuring apparatus () as well as a method for the operation of the measuring apparatus are provided.

A method and device, for enriching a gas flow with an anesthetic, include a gas mixer (), with gas inlets () and one or more gas outlets (), and an anesthetic dispenser () 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 (). A control valve () is arranged fluidically in series with the anesthetic dispenser (). The gas outlet is connected to the patient connector () via a gas channel (), arranged fluidically parallel to the anesthetic dispenser () and in which at least another control valve () is arranged. A control unit () 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 ().
