A non-sterile fabric and foam composite material in the form of a thick band intended to be used to produce a custom-made, figure-of-eight shaped arm sling. Suitable lengths are cut, typically from a roll or a dispenser box, and plastic clips used to fashion two loops, one for round the neck and the other for round a wrist (collar and cuff), to provide support for the arm. It consists of a foam core with a fabric covering and is typically used to immobilize forearm, elbow, humerus or shoulder injuries. This is a single-use device.
