ABSTRACT:
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.
