ABSTRACT:
A lifting device which may be rolled to a position under an object to effect lifting thereof. The device of the invention is particularly useful in the lifting of human patients as it accomplishes lifting without sliding action between the patient and the exterior of the lifting device. The lifting device includes a hollow member of flexible material with a recess running from end to end entirely through the member. The member also defines an enclosed chamber surrounding the recess and having a generally elongated, flattened, toroidal configuration. Preferably, the chamber is filled with a fluid medium for supporting the member and maintaining its shape. A protecting device is engageable both with said recess and with the exterior of said member to cover and protect the same. At least part of the surface of the hollow member which faces the interior of the chamber may include a layer of lubricant thereon to facilitate rolling of the member.
