Abstract:
A medical device comprising:a patient support device having a displaceable patient support plate having a head end and a foot end, and a left side and a right side proceeding longitudinally between said head end and said foot end; a manually actuatable operating unit for controlling displacement of said support plate in different directions, dependent on respective manual actuation actions performed on said operating unit according to a directional function of said operating unit, which sets a relationship between said actuation actions and said different directions said operating unit being selectively positionable at different positions relative to said support plate, said operating unit being positionable at any one of said head end, said foot end, said left side and said right side of said support plate; a detector and changeover unit connection to said operating unit for detecting a position of said operating unit relative to said support plate and for changing said directional function of said operating unit dependent on the detected position of said operating unit; and said operating unit having manually actuatable first, second, third and fourth actuation elements with which said actuation actions are performed as respective actuations of said first, second, third and fourth actuation elements, and said detector and changeover unit switches said directional function, when said operating unit is detected at said left side, so that actuation of said first actuation element longitudinally displaces said support plate toward said head end and so that actuation of said second actuation element longitudinally displaces said support plate toward said foot end, and said detector and changeover unit switching said directional function, when said operating unit is detected at said right side, so that actuation of said first actuation element longitudinally displaces said support plate toward said foot end and so that actuation of said second actuation element longitudinally displaces said support plate toward said head end, and said detector and changeover unit switching said directional function, when said operating unit is detected at said foot end, so that actuation of said third actuation element longitudinally displaces said support plate toward said head end and so that actuation off said fourth actuation element longitudinally displaces said support plate toward said foot end, and said detector and changeover unit switching said directional function, when said operating unit is detected at said head end, so that actuation of said third actuation element longitudinal displaces said support plate toward said foot end and so that actuation of said fourth actuation element longitudinally displaces said support plate toward said head end.
