Multi-Layered Dressings/Island Dressings

Multi-Layered Dressings/Island Dressings


A multi-layer dressing and island dressings are composed of a nonwoven dressing material such as an antimicrobial, absorptive foam, hydrogel, or hydrocolloid. This inner material contains a wound contacting non-absorbent, non-adhering porous polymeric film, which can be impregnated with a broad-spectrum antimicrobial agent.

The second layer comprising a semi-permeable continuous polymeric film joined to the first layer to form a sealed interior reservoir compartment. The absorbent material positioned within the interior reservoir compartment collects discharged exudate from a wound.  The exterior layer is bordered by a skin friendly medical grade adhesive.

Multi-layer dressings and island dressings utilizing nonwovens have a therapeutic effect and aid the healing process, especially when used where wounds have high exudates. These types of wound dressing and the specific materials used are designed to maintain the correct moisture conditions around the wound.  The material is hydroscopic; it attracts and holds water without actual wetting of the wound.   Using nonwoven material results in the rapid uptake and retention of exudates from the wound. This is essential in creating an optimum environment for healing and preventing bacterial growth.
