Epigard | Material, effect

Epigard’s unique feature is the twoply material, which was developed by imitating the microanatomy of the human skin.
The thin top surface made of Teflon (polytetrafluorethylene) is permeable to air, but prevents bacteria from penetrating the wound and secretions from seeping through.

The underside forms an open matrix of soft, pliable polyurethane. The side that faces the wound ensures rapid cleansing and good preparation of the wound surfaces. Epigard is sterile and disposable.

The mechanism of action

Epigard sticks rapidly and effectively through thrombogenic adhesion and coagulation of the exudate on the wound bed. This rids the wound of necrotic tissue and exudate when the bandage is changed for the first time. During this wound cleansing phase, fibroblasts and vessels start growing in the wound area and the open-pored polyurethane foam.

After a few days a consistent, well vascularised wound bed is achieved, which can be covered with a secondary dressing.

Figure 1: The wound exudate adheres to the cavities in the polyurethane structure.

Figure 2: Necrotic tissue and wound exudate can be removed when the bandage is changed.

Figure 3: After the wound cleansing phase, fibroblasts and blood vessels begin to grow, which encourages a consistent and well vascularised granulation of the wound bed.
