The limb sheath is used to provide a waterproof cover for an injured limb, such as a burned limb or a limb which is bandaged or in a cast. The sheath has a water impervious sleeve made of a first plastics material. The sleeve has an open end through which a limb can be inserted. A sealing strip is fastened to and extends about the internal surface of the sleeve at the open end. The sealing strip is made of a second plastics material which is more highly plasticised than the first plastics material. There is also an elastic strap which is connected to and extends from the sleeve adjacent the open end. The strap is fastenable to itself by mating components of a self-contact fastener. In use with the sealing strip in contact with the limb, the strap can be stretched resiliently, wrapped about the open end and fastened to itself, thereby pressing the sealing strip against the limb to form a water-tight seal at the open end. |
