Patent ID: 8718898

Claim:
A stand for holding at least one medical device, comprising: a stand foot ( 6 ) for placing the stand ( 10 ) on a floor, the stand foot ( 6 ) including a plurality of casters ( 16 ) for displacement of the stand ( 10 ) relative to the floor; at least one sensor unit ( 22 ) configured to ascertain a displacement motion of the stand ( 10 ); a drive unit ( 18 ) configured to drive at least one of the casters ( 16 ) of the stand foot ( 6 ); and a control unit ( 20 ) configured to control the drive unit ( 18 ) such that the drive unit ( 18 ) assistively drives one or more of the plurality of casters ( 16 ) only when the sensor unit ( 22 ) detects a displacement motion of the stand ( 10 ); and a marking sensor configured to recognize a floor marking; wherein the control unit ( 20 ) is configured to control the drive unit ( 18 ) such that the drive unit ( 18 ) decelerates or stops the stand ( 10 ) when the marking sensor detects the floor marking and the control unit ( 20 ) ascertains that the floor marking would be traveled over if the displacement motion caused by a user continues; and wherein the sensor unit ( 22 ) includes a speed sensor configured to ascertain speed of the displacement motion; wherein the control unit ( 20 ) is configured to control the drive unit ( 18 ) such that the drive unit ( 18 ) drives the at least one caster ( 16 ) when the speed of the displacement motion, determined by the speed sensor, is greater than a preset minimum speed and/or less than a preset maximum speed; and wherein the control unit ( 20 ) is configured to control the drive unit ( 18 ) such that the drive unit ( 18 ) drives the at least one caster ( 16 ) to decelerate the stand ( 10 ) when the speed of the displacement motion, determined by the speed sensor, is greater than the maximum speed.
