Abstract
Abstract The invention relates to an apparatus for the preparation of decubitus ulcers on the human heel, said apparatus including a harness adapted to fit about the human foot and ankle, with said apparatus having a reservoir-cushion connected thereto such that when the user of the device is lying on his/her back the reservoir-cushion is positioned between the back of said user's ankle and the surface on which said user reposes causing the human heel to remain suspended above the surface on which said user reposes and therefore removes all pressure from the human heel.
