Key Features of Tielle Adhes. Dressings

Description Tielle Lite is an island dressing with a multi-layered structure consisting of a thin sheet of hydrophilic absorbent poly-urethane foam applied to the centre of thin polyurethane foam membrane coated with an acrylic adhesive. The inner surface of the polyurethane foam island is covered with an apertured plastic film made from ethyl methyl acrylate that acts as a low-adherent wound-contact layer. This film also reduces the loss of fluid by evaporation from the wound surface thus helping to maintain a moist wound environment. The wound contact surface of the dressing is covered with two pieces of paper coated with a release agent that act as a carrier and facilitate application. Tielle Lite is waterproof and the polyurethane foam backing forms an effective barrier to bacteria under normal conditions of use. The polyurethane foam backing is highly permeable to moisture vapour, a property that makes an important contribution to the total fluid-handling characteristics of the dressing.
