The Smith & Nephew Renasys Negative Pressure Dressings are white foam dressings specifically designed for use with the Renasys negative pressure wound therapy system. These sterile foam dressings are intended to be placed within the wound bed to facilitate the negative pressure therapy. The white foam material is designed to evenly distribute the negative pressure across the wound surface. When used with the Renasys pump, these dressings help to remove exudate and promote wound healing. They are an essential component of an effective negative pressure wound management system.
