A bed ( 10 ) or trolley or similar consists of a platform ( 20 ) comprising a back section ( 21 ), seat section ( 22 ), thigh section ( 23 ) and foot section ( 24 ). The "auto contour" controls are configured such that when the sections ( 21, 23, 24 ) are driven from a flat condition, the back ( 21 ) and thigh ( 23 ) sections are moved simultaneously, until they reach the same angle. The thigh section ( 23 ) then remains at that position and the back section ( 21 ) continues until it reaches its maximum position. To lower the sections using the "auto contour" controls only the back section ( 21 ) is driven down until it reaches the equivalent position to the thigh section ( 23 ) and then both sections ( 21, 23 ) are driven down simultaneously. The patient is held in a relatively constant position, thereby reducing the shear between the patient's skin and the support surface. |
