Abstract
Abstract Hammock portion of a tiltable stretcher supports the lower half of patient at a first elevation in prone position while a tray portion of the stretcher supports head, arms and shoulders at lower elevation until stretcher is swung to a near-vertical position where tray may be adjusted to a suitable angle facilitating reading, eating, playing games and the like. The device may be provided with handrims which drop below level of stretcher in horizontal position to eliminate obstacles during patient transfer.
