<p>An apparatus (100, 200, 300+301, 400, 500, 600, 700) is disclosed for placement on a support surface (101, 201, 301, 401, 601, 701) between the support surface (101, 201, 301, 401, 601, 701) and a living being (108), wherein the living being (108) has a bony prominence (103, 104a, 104b, 105a, 105b, 626, 627a, 627b, 628a, 628b, 629a, 629b, 630a, 630b, 631). The apparatus (100, 200, 300+301, 400, 500, 600, 700) includes a first zone (112, 212, 312, 412, 512, 612, 712) having a first coefficient of friction, the first zone (112, 212, 312, 412, 512, 612, 712) being config-ured for positioning proximate the bony prominence (103, 104a, 104b, 105a, 105b, 626, 627a, 627b, 628a, 628b, 629a, 629b, 630a, 630b, 631). A second zone (113, 213, 313, 413, 513, 613, 713) is adjacent the first zone (112, 212, 312, 412, 512, 612, 712), the second zone (113, 213, 313, 413, 513, 613, 713) having a sec-ond coefficient of friction higher than the first coeffi-cient of friction. The second zone (113, 213, 313, 413, 513, 613, 713) is configured for positioning remote from the bony prominence (103, 104a, 104b, 105a, 105b, 626, 627a, 627b, 628a, 628b, 629a, 629b, 630a, 630b, 631). A method of preventing or healing decubi-tus ulcers includes positioning the bony prominence (103, 104a, 104b, 105a, 105b, 626, 627a, 627b, 628a, 628b, 629a, 629b, 630a, 630b, 631) over the first zone (112, 212, 312, 412, 512, 612, 712) and positioning an area remote from the bony prominence (103, 104a, 104b, 105a, 105b, 626, 627a, 627b, 628a, 628b, 629a, 629b, 630a, 630b, 631) over the second zone (113, 213, 313, 413, 513, 613, 713).</p> |
