Douderm Signal Dressings

DuoDERM Signal® dressing is an adhesive, tapered edge, modern hydrocolloid wound dressing with a change indicator. It incorporates a unique ConvaTec hydrocolloid formulation that distinguishes it from other hydrocolloid dressings. The adhesive hydrocolloid matrix and the outer film on DuoDERM Signal® dressing is permeable by moisture vapor and provides an occlusive barrier against bacteria, viruses, dirt and water. DuoDERM Signal® Dressing is indicated for the management of lightly to moderately exuding wounds.


  • Dressings have a visual indicator which indicates when a dressing needs changing, reducing premature dressing changes.
  • A thin, smooth, low-friction backing is designed to reduce shearing that can prematurely dislodge the dressing.


  • A thin polyurethane film provides a bacterialand viral barrier when the dressing remains intact and without leakage.
  • The film provides a waterproof barrier over the dressing.
  • It is easy to apply and can be removed without damaging newly formed tissue.
  • It helps to reduce bunching and the effect of shear through tapered edges and a smooth surface.
  • It helps to prevent damage to the wound bed on removal through a unique gelling action, ensuring maximum comfort.


  • The translucent backing enhances dressing placement and initial monitoring of the wound
  • The tapered edge contours to difficult areas


  • Remove the dressing from the protective sleeve.
  • Peel back the main white release paper and the two small margin tabs and apply the dressing wings to the back of the heel.
