Abstract
A medical device is configured such that operator inputs are more convenient and more reliable via a touchscreen display. The medical device includes a touchscreen having two redundant finger-position sensors. At least one of the sensors has additional piezoelectric elements, which can modify at least partial areas of the touchscreen such that the sensors are differentiated from their surrounding areas by an elevation, a recess, a vibration or a change in the surface roughness sensed. A control unit differentiates intentional and unintentional operating entries, and in the event of failure of the visual display device of the touchscreen display ensures at least a restricted operability of the touchscreen display.
