Abstract: The posture of a patient on a nursing bed can be changed by separating a bed tray that is in a base of the nursing bed from leg-side lifts and hand-side lifts. Leg-side and head-side nets are fully stretched, and the body of the patient is supported on the leg-side net and the head-side net above the bed plate using the leg-side lifts and head-side lifts while the patient faces upwards. An elongate cushion is then placed lengthwise on the bed plate. The body of the patient is then lowered until the body comes into contact with the elongate cushion. Winding drums are then rotated to pull on the nets on the side toward which it is decide to turn the patient so as to loosen the leg-side and head-side nets, so that the body of the patient rolls on the elongate cushion toward that side, and so that the body of the patient is supported by the bed plate. The elongate cushion is then subsequently removed from the bed plate.
