Description of the DuoDerm Patch
The DuoDerm CGF is a hydro-adhesive patch that features an inner layer that contacts the wound, and comprises of adhesive elements that are united in a polymer sticker and an outer sponge-like poly-urethane layer.
The patch is maintaining a humid environment on the wound which helps in its healing, and also speeds up the aytolytic process of the nekromas removal. Moreover, it makes the movement of the epithelial cells easier, allowing for the easy removal of the patch without injuring the newly formed tissue. The patch can be used either as a primary, or as a secondary patch in combination with other sprawling patches. The adhesive layer contains polymers that improve its ability to contain liquids, forming a gel with adequate adherence.

Precautions and Remarks
This product is for one use only. Reusing this product may lead to infections, product malfunctioning, or inability to adhere to the wound properly. The removal of dead tissue may make the wound appear larger after the first few patch changes. The presence of micro-organism colonies in the chronic wounds is a common phenomenon and doesn’t constitute a sign of a problem with the use of the patch. The patch may be used in wounds that are infected under the supervision of medical staff, while the patient also receives antibiotic medication, and the wound is periodically checked. In the cases of anaerobic infection, the use of this patch isn’t recommended. For more information, visit

Placing the DuoDerm CGF Patch
Place the patch in such a way that it covers the edges of the wound by at least three centimeters. Clean the wound area, rinse well, and dry the skin around the wound.
– Remove the protective silicone sheet from the back side of the patch, minimizing the contact of the fingers with the adhesive layer.
– Carefully roll the patch on the wound. Do not stretch it.
– Gently apply some pressure on the patch to ensure a perfect sticking result.
– If needed, fix the edges of the patch by using hypoallergenic tape.
Notice: As the liquids of the wound are absorbed by the patch, the forming of the gel may become obvious on the outer layer like a bubble.
Removing the Patch
Press the skin gently using one hand, while carefully raising the edge of the patch with the other hand.
The patch is preserved well in room temperature conditions. Avoid high temperatures or freezing.
