Abstract: 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).

Abstract: An anesthetic dispensing device (1), to which a carrier gas stream is fed for enriching with anesthetic, has the gas stream split into two partial gas streams, one of which flows through a bypass channel (7) unchanged and the other of which is fed to an evaporation chamber (9), where the partial gas stream is saturated with anesthetic. In a mixing point (6), both partial gas streams are mixed to form an anesthetic gas stream, which leaves the anesthetic dispensing device through the anesthetic gas outlet (4). A control unit (2) is provided that is configured to generate a control signal for an electric motor drive (14) for adjusting the valve opening of the valve element (15) on the basis of a concentration of the anesthetic in the anesthetic gas needed at the anesthetic gas outlet (4) and at least one temperature-specific correction factor.

Abstract: A process is provided for monitoring a patient being anesthetized, as well as a process for determining a combined effect of different anesthetics used. Devices for carrying out the processes are also provided.

Abstract: A device (13) is provided for use with a treatment device for treating a patient. The device (13) includes a detection device (17) for detecting at least one transition of the patient's treatment from a first phase of treatment to a second phase of treatment. A signal device (25) for sending at least one signal when the transition is detected. It proposes, furthermore, a workstation equipped herewith.

Abstract: A data processing device is provided for an anesthesia device for feeding an intravenously administered hypnotic, a volatile hypnotic, and an opioid such that the volume flow can be adjusted. The device determines and standardizes the effective concentrations of the anesthetics. A pharmacokinetic model adds up the standardized concentrations of the hypnotics to a total hypnotic concentration. An isobole is calculated based on a coordinate plane with a total hypnotic concentration axis and an opioid concentration axis, as a function of the currently determined concentrations. The system displays a two-dimensional action diagram with the y-axis as an indicator of the total hypnotic concentration and the x-axis as an indicator of the standardized opioid concentration. The calculated standardized total hypnotic concentration and opioid concentration and the isoboles determined are displayed. The display is adapted to changes occurring in the isoboles determined in the course of time.

Abstract: A testing device (10), an infusion pump or another medical device function testing method, to an anesthesia apparatus or respirator (AB) and to a computer program product are provided for testing the function of an infusion pump (G). The testing device (10) is preferably implemented on the anesthesia apparatus or respirator (AB) and comprises a memory (MEM), a test module (T) and a controller (C). The test module (T) sends a test command (20) to the infusion pump (FG), which sends a response (30) back to the controller (C) after execution of the command. The control (C) can then compare the response (30) received with a reference response (30?) for agreement in order to send a successful function test result.
