DuoDerm Signal - Hydrocolloid Sacral Dressing protects the tailbone area from constant pressure while also healing any exuding wounds in that area of the body. It is specially shaped to fit the contours of the sacrum region, which provides comfort and proper coverage. The adhesive border helps keep the wound dressing secure and has tapered edges that prevent the dressing from rolling off the skin. This product also has an indicator that visibly alerts a caregiver when it is time to change the dressing.
