    摘要： An anesthetic metering device with a bypass stream 5 passed from a gas inlet opening 2 via a bypass valve 3 to a gas discharge opening 4 and with a vaporizer chamber stream 7 flowing from a vaporizer chamber 6 via an adjusting device. Accurate metering is possible even in the case of anesthetics with low boiling points by manufacturing the vaporizer chamber 6 at least at the saturation vapor pressure of the anesthetic 22. The adjusting device includes a differential pressure transducer 9 connected on both sides of the bypass valve 3 and a metering valve 10, wherein the metering valve 10 is actuated by the output quantity 11 of the differential pressure transducer 9 via a proportional member 12 so that the concentration is adjusted via the variable transmission ratio of the proportional member 12.

    摘要： A metering device for a liquid anesthetic that is fed from a reservoir via a supply line into a heatable intermediate container maintained under pressure, from which gaseous anesthetic is fed via a metering valve into a fresh gas line. Accurate metering, which can be better monitored, is provided for low-boiling anesthetics. A supply unit 7 is mounted in the supply line 5, and liquid anesthetic is transported by the supply unit 7 into the intermediate container 6 until it is filled up to a predetermined filling level. A heating device 12 stabilizes the temperature of the liquid bath and ensures a sufficiently high vapor pressure of the gaseous anesthetic above the liquid phase. The anesthetic vapor is sent via the metering valve into the fresh gas line.

    摘要： An anesthetic metering device is provided with a temperature-stabilized anesthetic vapor source, from which anesthetic vapor 14 is metered into a carrier gas stream via a delivery line 8 with a metering valve 11 that can be controlled by a control unit 6. The arrangement is provided so that uncontrolled evaporation of anesthetic is prevented. To accomplish this task, the anesthetic vapor source is designed as a vaporizer chamber 2 filled with liquid anesthetic 3, and a gas delivery element 9 generating the metering pressure P.sub.I is present in front of the metering valve 11.

    摘要： A process for calibrating a flow sensor in a respiratory system, with final control elements arranged in the respiratory system for influencing the respiration gas stream, is to be improved in terms of the influence of the qualitative gas composition of the respiration gas. To accomplish the task, the final control elements 4, 11 are switched, for calibration, over to a closed respiratory system with directed respiration gas stream. The drive unit 13 feeds the respiration gas present in the respiratory system through the flow sensor 9 according to a predetermined time-volume relationship. A calibration value for the flow sensor 9 is formed by comparison of the time-volume relationship with the measured signal of the flow sensor 9.

    摘要： A medical apparatus 1 is equipped with: a metering device (2, 3) for a fluid medium (4, 5); a computer unit 19 controlling the metering device (2, 3) according to individual input quantities; a display screen 12 for displaying possible input quantities inside menu structures; a rotatable knob 13 for selecting an input quantity; a pressure-actuated acknowledgment switch 15 for assuming the selected input quantity as a setting value for one of the metering devices 2; and, a further switch 16. This medical apparatus facilitates the correction of incorrectly assumed input quantities. This is provided in that the further switch is configured as a pull switch or slide switch 16 activated by a rotatable knob 13. The pull or slide switch 16 transmits a signal (S1) which cancels the assumption of the input quantity. The signal S1 is transmitted to the computer unit 19 or to the metering device 2 or to both.
