<p>PROBLEM TO BE SOLVED: To provide a technique capable of easily and reliably preventing the development of a bedsore in a person lying on a bed surface.SOLUTION: A bed surface 30 is divided in two in a right and left direction of a person lying on the bed surface 30 and also divided in four in a head and foot direction so as to set division areas 30a-30h. Driving devices 40a-40h for moving the respective division areas 30a-30h in a direction to intersect with the bed surface 30 are arranged in the respective division areas 30a-30h. An imaging device 70 captures the image of a person lying on the bed surface 30 and outputs imaging information. A control device 80 discriminates a continuous time when each one of predetermined regions of the person lying on the bed surface 30 has contact with the bed surface 30 on the basis of the imaging information. Then, the control device 80 controls the respective driving device 40a-40h to reduce loads to be applied to the predetermined regions where the continuous time of a contact state with the bed surface 30 becomes equal to or more than a set time.</p> |
