Medical apparatus having a metering device
First Claim
1. A medical apparatus comprising:
- a first metering device for metering a first fluid medium;
a second metering device for metering a second fluid medium;
a display device having a display screen for displaying a first menu structure including a first plurality of input quantities and a second menu structure including a second plurality of input quantities;
a computer unit for controlling said metering devices in accordance with individual ones of the input quantities from said menu structures;
a single rotary knob for selecting one of said input quantities of said first menu structure;
a pressure-actuated acknowledgment switch operatively connected to said single rotary knob so as to be actuable by said single rotary knob to issue an assuming signal (S2) for assuming the selected input quantity as a setting value for one of said metering devices;
a pull or slide switch operatively connected to said single rotary knob so as to be actuable by said single rotary knob to issue a cancelling signal (S1) for cancelling the assumption of said selected input quantity as said setting value; and
,circuit means for transmitting said cancelling signal (S1) to at least one of said computer unit and said metering devices.

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.
