Patient Support with Air Bladder Control Sensitive to An Orientation Angle Sensor

摘要

A patient support includes a cover defining an interior region, an air permeable first layer located in the interior region, and a first air supply coupled to the first layer to provide air flow through the first layer. The patient support also includes a plurality of air bladders located beneath the air permeable first layer and a second air supply coupled to the air bladders to selectively inflate and deflate the air bladders. An angle sensor is located in the interior region in an articulatable portion of the patient support. A controller is coupled to the first and second air supplies and the angle sensor to control inflation and deflation of the air bladders in response to an angle signal received from the angle sensor and to control air flow through the air permeable layer in response to the angle signal.
