  • Patent number: 5458617
    Abstract: For applying traction to an arm or a leg, an elongated body of elastic fabric is provided, which has a plurality of evenly distributed pockets that are elongated transversally of the body. Thin lead strips fit in the pockets as stiffeners. Complementary hook and loop fasteners secure the device around the girth of the arm or leg, so that all of the limb is surrounded by stiffener strips. The inner face of the elastic fabric is provided with a layer of anti-slip material, such as foam rubber, which extends beyond the elastic fabric, both lengthwise and widthwise, of the device. By preference, the device is arcuate in plan and the pockets and stiffener strips correspondingly trapezoidally shaped, when intended to fit around the tapering part of a limb.
