Non-slip bandage
First Claim
1. A resiliently stretchable bandage having a non-adhesive surface which resists slipping when the bandage is wrapped around a limb under tension, the bandage including one or more areas of slip resistant material and one or more areas lacking slip resistant material, the maximum extension of the bandage being up to 200% of its relaxed length, and the bandage having an elastic modulus of at least 400 g, the elastic modulus being expressed as the mass which would have to be hung from the bandage to extend it by 40% of the additional length of the bandage when extended from its relaxed state to substantially its maximum extended length, wherein the slip resistant material is slip resistant relative to human skin, and wherein the resilient stretchability of the bandage, the modulus and the areas of slip resistant material permit the location and magnitude of the compressive force resulting from such wrapping to be freely varied.

Abstract
In the field of bandages it is known to provide a non-slip coating to one surface of a bandage. However, previous such bandages have suffered numerous disadvantages. The disclosure relates to a bandage (1) having a resiliently stretchable, non-slip coating (3) applied to it in wavy lines extending along the length of the bandage (1). The non-slip coating is such as to provide slip resistance between the bandage (1) and the human skin, to which the bandage (1) may be applied in a compressive manner. An advantageous feature of the invention is the use of a barb hook-type fastener (5,13) the shear force which acts in a plane approximately coinciding with that of the outer surface of the bandage (1), thereby reducing the tendency of the bandage to peel apart as a result of forces arising from the compressive application of the bandage to e.g. a human limb.
