Flow sheets, labels, measuring tapes, skin markers, tracing materials, and other products specifically designed for wound assessment, measurement and documentation. Tracings are used to measure the surface of a wound and provide a clear, visual picture of how a wound appears without the use of a camera. Wound measurement tools are used to determine length, width, and depth. They are available in a wide variety of materials, including plastics, paper, or soft film and as single-patient use or reusable.
