Orthopedic liner for rolling on skin of amputation stump of patient, has layer made of chemical vapor deposited poly p-xylylene and exhibiting property of non-adherence to skin, and another layer made of polymeric cushion material

摘要

The liner has a first layer (1) for contacting a skin, and a second layer (2) exhibiting a damping function. A third layer (3) is made of elastic knitted fabric, and the first layer is made of Parylene (RTM: chemical vapor deposited poly(p-xylylene)) and exhibits a property of non-adherence to the skin, where average thickness of the first layer is 0.5-5 micrometer. The second layer is made of a polymeric cushion material i.e. polymer gel. The elastic knitted fabric comprises a mixture of polyester, cotton and spandex, where thickness of the elastic knitted fabric is 0.8-2.5 mm.
