Abstract
Abstract An oscillatory bed for providing improved patient care in a hospital, nursing home or home health care setting. The oscillatory bed is characterized by having hinged, adjustable side panels along opposite sides of the length of a cradle located in the oscillating bed, which can be raised from a flattened position to form a "U" shaped cradle configuration during the operation of the bed. The adjustable side panels can be quickly lowered to the flattened position for emergency treatment of the patient or in changing of the bed. The oscillatory bed also includes a linear actuator in a head board section and in a foot board section. By raising the head board section, the patient's head and upper body are raised above the patient's feet. Also, the foot board section can be raised, and in turn the patient's feet are raised above the patient's head and upper body. The cradle of the oscillatory bed is further characterized by having a cradle base which has two components; an upper cradle portion with cradle head panel and a lower cradle portion. The cradle head panel is attached to a linear actuator which raises the cradle head panel and in turn allows the patient's upper body and head to be raised up to 30 degrees above a plane of the cradle base. The oscillatory bed further includes electronic microprocessor controls that allow continuous oscillations of the cradle with cycle times between 30 to 240 minutes or the oscillations can be programmed to stop at three locations for interval periods of 5 to 120 minutes before resuming the oscillations. The interval stops can occur when the bed is in a horizontal position, in a raised left side position and a raised right side position.
