Abstract
A self-adhesive bandage for prevention and treatment of skin breakdown by relief of friction and shear forces. The bandage includes a pair of thin film membranes, one of which is a portion of a dome and is free to move a limited distance with respect to the other. The dome is located on a skin contact layer that can be adhered to one's skin. A method of making such a bandage includes forming a dome in a flexible film and adhesively attaching a skirt surrounding the dome to a skin contact layer.
