DuoDerm Signal Hydrocolloid Dressing, 4 x 4 Inch

ConvaTec DuoDerm Signal Hydrocolloid Dressing, 4 x 4 Inch

The ConvaTec DuoDerm Signal Hydrocolloid Dressing is a sterile, self-adhesive wound dressing designed to support moist wound healing for a range of light to moderately exudating wounds. Ideal for pressure injuries, minor burns, abrasions, and other partial- or full-thickness wounds, its adhesive hydrocolloid matrix conforms gently to the skin while helping to manage exudate and protect the wound bed.

DuoDerm Signal works by interacting with wound fluid to form a soft, protective gel that maintains a moist wound environment, which supports the body's natural healing process. The dressing's outer film and hydrocolloid matrix are permeable to moisture vapor, allowing the wound to breathe while creating an occlusive barrier against bacteria, viruses, dirt, and water. This helps reduce the risk of contamination between changes and can allow patients to bathe or shower with greater confidence. A built-in change indicator provides a helpful visual cue to signal when the dressing may need to be replaced.

This 4 x 4 inch (10 x 10 centimeter) dressing is available in multiple options, including a Single dressing or a Box of 5, so you can choose the quantity that fits your care routine. Many wound care supplies like this are FSA/HSA eligible. Please select your preferred option below to add it to your cart.
