Abstract
Protective bandages in accordance with this invention include an anchoring strip having a protective layer on a lower surface thereof for overlying a desired area on a person's skin. Force-transmission-impeding means is provided on the side of the anchoring strip opposed to the side including the protective layer. The force-transmission-impeding means includes a top sheet adhered adjacent peripheral edges thereof to an upper surface of the anchoring strip to define an internal compartment between the anchoring strip and the top sheet. A compressive cushioning member is provided within the internal compartment for absorbing compressive forces, and low friction, relatively movable confronting surfaces are provided within the internal compartment spaced from the upper surface of the anchoring strip to absorb shear forces imposed upon the bandage. In certain embodiments of this invention, two pairs of low friction, relatively movable confronting surfaces are provided, whereas in another embodiment of this invention only one pair of low friction, relatively movable confronting surfaces is provided.
