A mains electricity (AC-powered) assembly of devices used to transfer a supine patient, typically from his/her bed or transport stretcher to an operating table or vice versa. It is usually installed in large operating room (OR) complexes and serves as a sluice providing demarkation between the OR staff and the ward staff/porters and related devices. It may be designed as a motorized belt that is wider than the length of the patient and that rotates around a moveable pick-up plate which feeds in under the patient, drawing him/her onto the belt and depositing him/her onto an adjacent surface. It is typically fully automated, requiring no human intervention other than to operate the controls.
