DuoDERM Signal Hydrocolloid Dressing Features

DuoDERM Signal - Design Features:

  • Dressing mass contains hydrocolloids
  • Thin, low-friction backing helps reduce shearing that can lead to premature dislodging of the dressing
  • Provides a waterproof barrier to protect the wound and the dressing
  • Tapered edge easily contours to difficult areas like heels, buttocks, sacrum, elbows, and trochanters
  • Translucent backing promotes initial wound monitoring and dressing placement
  • Polymers enhance the exudate absorbing capacity of the DuoDERM dressing by forming a cohesive gel
  • Outer film and hydrocolloid matrix allow moisture vapor to pass through
  • Used as a primary dressing for low-to-moderately exuding wounds
  • Can also be used as a secondary dressing to securely hold Aquacel or Aquacel Ag Dressing in place
  • Beige in color

DuoDERM Signal - Performance Features:

  • Absorbs wound fluid and creates a moist wound-healing environment
  • Can be applied and removed without damaging newly formed tissue
  • Smooth surface and tapered edges reduce bunching and the effect of shear
  • Wound fluid seems like a bubble heading towards the indicator line
  • Helps in removing non-viable tissue from the wound, without damaging the newly formed tissue
  • Can be used alone or in combination with other wound care products as recommended by the healthcare professional
  • Acts as a barrier against viral, bacterial, and other external contaminants
  • Reduces the risks of exposure to infectious or nosocomial agents
  • Blocks the passage of bacteria and the Phi-X 174 virus, provided that the dressing remains intact and there is no leakage
  • Note: Use of DuoDERM dressing does not guarantee or warrants against AIDS or Hepatitis B Virus Transmission

When to use DuoDERM Signal Dressing?

  • Lightly to moderately exuding wounds
  • Minor scalds and burns
  • Minor abrasions
  • Minor cuts
  • Lacerations

Under medical supervision, DuoDERM hydrocolloid dressing may be used for the following:

  • Leg ulcers (venous stasis ulcers, leg ulcers, and arterial ulcers of mixed etiology)
  • Pressure ulcers/sores (stage I and stage II)
  • Second-degree burns
  • Diabetic ulcers
  • Surgical wounds
  • Traumatic wounds

Instructions for using DuoDERM Signal Dressing

Wound Site Preparation and Cleansing:

  • Before using the dressing, clean the wound with an appropriate wound-cleansing agent or normal saline.
  • Dry the surrounding skin.

Applying DuoDERM Signal Dressing:

  • Choose a Convatec DuoDERM Signal dressing size and shape to ensure that it is 1-1/4 inches (3 cm) larger than the wound area in any one direction.
  • Remove the release paper from the back being careful to minimize finger contact with the adhesive surface.
  • Hold the dressing over the wound and line up the center of the dressing with the center of the wound. Place the dressing directly on the wound.
  • For difficult-to-dress anatomical locations, such as heels or the sacrum, a supplementary securing device, such as tape, may be required.
  • Discard any unused portion of the product after dressing the wound.

Removing DuoDERM Signal Dressing:

  • Convatec DuoDERM Signal dressing should be inspected frequently for leakage, rolling up of the edges, and/or whether any part of the bubble has reached the change indicator. If any of these occur, the dressing should be changed. As wound fluid is absorbed by the dressing, gel formation may be visible through the dressing.
  • The dressing should be changed when: clinically indicated, when strikethrough occurs, or up to a maximum of seven days. The wound should be cleaned at appropriate intervals.
  • Press down gently on the skin and carefully lift one corner of the dressing until it no longer adheres to the skin. Continue until all edges are free. Carefully lift away the dressing.

Precautions to be taken while using DuoDERM Dressing:

  • Sterility is guaranteed unless the pouch is damaged or opened prior to use. Single-use only.
  • This wound dressing should not be used with other wound care products without first consulting a healthcare professional.
  • During the body’s normal healing process, non-viable tissue (autolytic debridement) is removed from the wound, which could make the wound appear larger after the first few dressing changes. If the wound continues to get larger after the first few dressing changes, consult a healthcare professional.
  • Should you observe irritation (reddening, inflammation), maceration (whitening of skin), hypergranulation (excess tissue formation), or sensitivity (allergic reaction) consult a healthcare professional.
  • Frequent dressing changes on wounds with damaged or delicate skin surrounding the wound are not recommended. The wound should be inspected during dressing changes. Contact a healthcare professional if:
    • signs of infection occur (increased pain, bleeding, wound drainage),
    • there is a change in wound color and/or odor,
    • the wound does not begin to show signs of healing and
    • any other unexpected symptoms occur.
  • The dressing may be used on infected wounds only under the care of a healthcare professional.
  • The use of this dressing neither guarantees nor warrants against AIDS or Hepatitis B Virus transmission.

In addition, for leg ulcers (venous stasis ulcers, arterial ulcers, and leg ulcers of mixed etiology), diabetic ulcers, pressure ulcers/sores, second-degree burns, surgical wounds, and traumatic wounds:

  • Treatment of the wound types listed above should be under the supervision of a healthcare professional.
  • Appropriate supportive measures should be taken where indicated (e.g. use of graduated compression bandaging in the management of venous leg ulcers or pressure relief measures in the management of pressure ulcers/sores).
  • Colonization of chronic wounds is common and is not a contraindication to the use of the dressing. DuoDERM dressing may be used on infected wounds under medical supervision together with appropriate therapy and frequent monitoring of the wound.
  • The control of blood glucose, as well as appropriate supportive measures, should be provided for diabetic foot ulcers.


  • DuoDERM Signal should not be used on individuals who are sensitive to or who have had an allergic reaction to the dressing or its components.

Storage Instructions:

  • Store at room temperature (10º C - 25º C/50-77º F).
  • Keep dry.
