ALLEVYN Adhesive consists of a highly absorbent hydrocellular foam pad held between an adhesive perforated wound contact layer and a highly permeable outer top film5,6.
1. Breathable Top Film6
The outer polyurethane top film switches to become more breathable in the presence of exudate.
It also helps to prevent strikethrough and provides an effective barrier to bacteria and minimises the risk of cross contamination8.
2. Highly Absorbent Foam Core5
The hydrocellular foam core is highly absorbent, providing absorption capacity for up to 7 days5.
3. Non-Adherent Wound Contact Layer4,5
The wound contact layer has a low allergy based adhesive3, which adheres well to intact skin, will not stick to the wound and has a proven low risk of skin irritation.
The unique triple layer technology effectively manages exudate helping to ensure that the wound is kept at optimum moisture levels to support moist wound healing1. It does this by:
- Transpiring enough fluid to keep the dressing comfortable and conformable1.
- Retaining enough fluid to keep a healthily moist wound environment1.
- Absorbing enough fluid to remove unwanted exudate and cellular debris1,10.
