ABSTRACT:
The application discloses a rigid or semi-rigid, two-part confining cover for a patient in a conventional hospital bed. The problem dealt with is that of a disturbed patient who would normally require confinement by ties, straps, or other conventional restraints, together with, in many cases, round-the-clock guarding by an attendant. The mattress support frame of a hospital bed usually has one or more horizontal pivot joints, the most important of which enables tilt-up of the back of the bed. Knee lift provisions are generally provided. The disclosed cover includes forward and rearward open-bottom shells, hinged to one another about the hinge axis of the bed used for tilt-up of the back part of the bed. The front shell has side walls rising from the longitudinal edges of the bed frame, forward of the aforementioned pivot axis, a front end closure, and a top closure. The back shell has side walls rising from the longitudinal edges of the bed frame from this pivot axis back, a rear end wall, and a top wall. The rear end of the front shell and the forward end of the rearward shell are fitted together in a manner to form a closure throughout the range of tilting of the rearward shell. The shells are perforated for air circulation, and are commodious enough to permit the patient adequate space for relatively free movement inside the closure. Access doors are provided.
