Abstract
A patch of low friction materials, such as a film of polytetrafluoroethylene is sized to provide an area of low friction support for a portion of a human body relative to an object such as a shoe or prosthetic socket. The patch can be lined with foam, or preferably, a stretch fabric so that it will fit around irregular contours of the shoe, or socket, or the skin itself. The patches reduce shear trauma in critical load areas. After identifying regions of high loads, the method comprises applying the patches as needed to avoid sores, calluses, blisters and abrasions.
Claims12
A patch for reducing friction between a portion of the skin of a person and an object supporting that portion of the skin, comprising a patch of size to fit over the desired portion of the skin and comprising a layer of film with an exterior surface having a coefficient of friction substantially equal to that of polytetrafluoroethylene, a bonded stretch fabric on one side of the film opposite from the exterior surface, said exterior surface providing an interface surface between the portion of the skin and the object and a securing member for securing the patch into position on one of the object and skin.
A patch for reducing friction between portions of the skin of a person and an object supporting that portion of the skin, comprising a patch having a layer of polytetrafluoroethylene film with an exterior surface, and being in the range of 2.5 mils thick, a layer of stretchable fabric bonded to the film to cause the film to move with the stretch fabric, and a layer of pressure sensitive adhesive on the stretch fabric for securing the patch in position on one of the object and skin.
