Allevyn* Cavity

Allevyn* Cavity provides Allevyn hydrocellular technology in a unique 3 dimensional structure for effective management of deep wounds.



  • Core of highly absorbent hydrocellular foam chips
  • Outer non-adherent perforated film
  • Range of sizes and shapes
  • Soft pliable construction

Highly Absorbent

  • Allevyn Cavity dressings have been designed to overcome the problems associated with dressing deep wounds. Their high absorbency results from the ability of the encapsulated foam “chips” to absorb exudate not only by capillary action (as is the case with traditional absorbents), but also by absorption of fluid into the structure of the foam. The result is cost effective management of cavity wounds without the need for frequent dressing changes.
Highly Conformable to Wound Contours
  • Allevyn Cavity dressings are available in a range of sizes suitable for virtually all deep wounds. The dressing has been designed to be soft and pliable so improving the conformability and versatility of the product. Furthermore the dressing provides and maintains optimum contact with the wound surface as it absorbs, minimising the risk of abscess formation.
Easy to use and apply
  • Allevyn Cavity dressing are presented individually sterilised in convenient plastic trays. More than one dressing may be used in the same wound if necessary. The correct dressing or combination of dressings can be quickly and easily placed into the cavity, allowing more effective use of nursing time.
Superior Non-Adherency
  • The three-dimensional honeycombed outer surface of the Allevyn Cavity dressing provides a highly effective non-adherent wound contact layer, so minimising discomfort and trauma during dressing changes.
Promotes Faster Healing
  • The wound contact surface of the Allevyn Cavity dressing maintains a moist wound healing environment which prevents eschar formation and promotes faster healing.
Contraindications / Precautions


  • Allevyn Cavity should not be re-used.
  • Avoid using forceps to place the dressing into the wound as this may puncture the dressing.
  • Ensure the numbers of dressings used in the wound is noted on application and checked on removal.
  • Do not use Allevyn Cavity with oxidising agents such as hypochlorite solutions (eg. Eusol) or hydrogen peroxide, as these break down the foam filling of the dressings.

Step 3:
Cover the Allevyn Cavity dressings with an OpSite* Film Dressing. Alternatively an absorbent dressing pad and fixative sheet ( Hypafix* Non Woven Adhesive Dressing Sheet) may be used if the skin around the wound is very delicate, or use an Allevyn Adhesive dressing where exudate is heavy.

Alt Text
Step 4:
The frequency of change depends on the quantity of exudate and the condition of the wound. Typically, Allevyn Cavity can be left in place for 3 days from the start of treatment and this should be quickly extended to a weekly change.

Step 5:
Remove secondary dressing and carefully remove Allevyn Cavity using gloved hands.
