    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 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.

    摘要： A locking device 5 for a metering device 3 of an anesthetic vaporizer 1 with an unlocking device 6 for actuating the metering device 3 is provided so as to ensure blocking of the unlocking device 6 in operating states that are unsuitable for the operation of the anesthetic vaporizer 1. The locking device 5 is provided having a final control element 20, 24, 29 that covers a regulating distance that depends on a parameter influencing the operating state of the anesthetic vaporizer 1. This regulating distance of the final control element is transmitted to a blocking device 13 which blocks the unlocking device 6 if the values of the parameter are unsuitable for the operation of the anesthetic vaporizer 1.

    摘要： An electrode arrangement in transducers for the combined measurement of various physiological quantities includes adhesion areas for connecting the arrangement to the skin. To increase adhesion strength and to provide a better electric insulation between measuring electrodes in the transducer, a ring body which carries the electrodes is provided with an adhesive area which includes an electrolytically or electrically conductive doping zone that extends up to an outer edge piece of the ring body. The edge piece is made of electrically insulating material, one of the measuring electrodes is put into electric contact with the skin through the doping zone.

    摘要： An electrochemical measuring cell is disclosed wherein the diffusion membrane which separates the electrolyte from the ambient is made of an intrinsically-conductive and electrochemically active plastic. This way the diffusion membrane itself defines the measuring electrode of the measuring cell. This is a substantial advantage over known electrochemical measuring cells wherein the measuring electrode is defined by an electrically conductive layer applied to the surface of the diffusion membrane facing toward the electrolyte. By making the diffusion membrane from an electrochemically active plastic, a removal of the electrically-conductive layer from the diffusion membrane is prevented.

    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.
