Multiple ply managed friction material surface with smooth bonded seams

摘要

A substantially smooth, seamless managed friction material surface and apparatus for placement on a support surface between the support surface and a living being for preventing abrasion or decubitus ulcers in a living being. The managed friction material surface comprises a plurality of plies having a smooth side and a first, high friction zone and second, low friction zone. At least one adhesive ply is interposed partially between adjacent plies; and the plies are selectively bonded to form adjacent frictional zones of high and low friction. Unbonded plies are allowed to move substantially freely with respect to one another thus providing a lower friction zone. The apparatus comprises the managed friction material surface such that the bonded zone is configured for positioning remote the bony prominence and the unbonded zone for positioning proximate the bony prominence, seamlessly occupying different areas on the same side of the material surface.

1. A substantially smooth managed friction material surface for preventing abrasion or decubitus ulcers in a living being, said managed friction material surface comprising:
a plurality of plies, each ply having a smooth side; a first frictional zone; a second frictional zone; at least one adhesive ply interposed partially between adjacent plies; wherein the at least one adhesive ply is applied selectively between a first ply and a second ply of the plurality of plies and wherein when bonded, the first ply and the second ply are secured and movement restricted only where the at least one adhesive ply is interposed; and wherein when the first ply and second ply of the plurality of plies are selectively bonded at the at least one adhesive ply, the plurality of plies form a first frictional zone of higher friction and wherein the plurality of plies remain unbonded proximate the first frictional zone to form a second frictional zone of lower friction and wherein the adjacent plies are allowed to move substantially freely with respect to one another in the second frictional zone of lower friction.
