A device for recording and transferring the contours of a wound or opening in tissue of a human being to an adhesive wafer of a wound appliance is provided. The device includes a transparent polymer sheet having a first and a second surface, the first surface being non-adhesive and facing the wound or opening and the second surface having a central portion and an edge portion, with the edge portion being provided with an adhesive layer. The device is placed over the wound or opening and the contours are traced on the central portion of the device. The adhesive layer on the second surface is then adhered to the wafer so that the drawn image contacts the wafer and is directly imparted to the wafer.
