  • Patent number: 4092748
    Abstract: A patient handling system is disclosed which includes a novel patient handling sheet and a novel patient lift apparatus and a combination thereof. The patient handling sheet has spaced parallel longitudinal tubes to receive stretcher poles and longitudinally spaced transverse apertures in the tubes to permit either the grasping of the stretcher poles by the hands or by hook means attached to the lifting apparatus or use of the apertures as hand holds without the stretcher poles. The apparatus for lifting stretchers is generally rectangular, is wide enough to straddle the patient's bed, and is hinged at each corner so that it may be folded up and stored away when not in use. A frame locking means is used to prevent its folding when in use. A crane is provided at one corner to do the lifting.

The supporting straps extend over the shoulders, cross the wearer's back and engage the edges of the apron to secure the apron and the arm to the wearer's body and keep the weight from being borne by the neck of the wearer. Optionally a restraint strap secures the arm from horizontal movement.
