Durafiber

CE medical device, class IIb sterile dressing (Gamma rays) in gelling ethyl sulphonated cellulose fibres.
Useful for managing chronic and acute wounds, partial-thickness, full-thickness, or superficial granulating wounds. Examples include leg ulcers, pressure ulcers, diabetic ulcers, surgical wounds, secondary healing wounds, donor sites, fistulas and tunneled wounds, partial-thickness burns, traumatic wounds, and wounds prone to bleeding, such as mechanically or surgically debrided wounds.
The product does not contain natural resins and gums (latex) which represent a potential allergenic factor.
Available in various formats:
5cm x 5cm pack of 10 dressings, 10cm x 10cm pack of 10 dressings, 15cm x 15cm pack of 5 dressings, 2cm x 45cm pack of 5 dressings.

Mechanism of action
Ethyl sulfonation, like other chemical processes to which cellulose fibers may be subjected (e.g., carboxymethylation), makes the resulting Ethyl Sulfonated Cellulose (ESC) absorbent and gelling. When in contact with exudate, the ESC dressing absorbs it vertically, controlling its lateral dispersion; it gels and traps both the exudate and the bacteria it contains within its structure. This reduces the risk of maceration and prevents fluid leakage, even under compression. The gelling of the fibers allows the dressing to conform to the wound surface, maintaining a uniformly moist environment for healing on the wound bed and reducing empty spaces where bacteria could proliferate. The unique chemical treatment process also makes the gelled dressing highly resistant to shrinkage and highly tensile strength: even when applied to cavities or fistulas, the dressing does not tear easily during removal from wounds.

Composition and structure
Dressing made of ethyl sulfonated cellulose fibers. The dressing is made of a nonwoven fabric. The dressing absorbs and interacts with exudate, transforming into a soft, transparent, hydrophilic gel. 80% ethyl sulfonated cellulose fibers and 20% cellulose fibers.

How to use
The dressing can be left in place for up to 7 days or changed when clinically indicated (e.g., in case of exudate leakage or excessive bleeding). Local clinical protocol should also be taken into consideration.

Conservation
Store in a cool, dry place below 25°C, away from direct light.

Format
Packs of 10 or 5 dressings.
