Mode of Use/Application

Before applying the dressing, the wound bed should be cleansed carefully using existing clinical protocols. The skin surrounding the wound should be clean and dry. Choose an appropriate size to match the wound size. If necessary, fold or cut to adjust to wound size. For deep wounds, use the rope dressing format. Pack lightly. Apply dressing on the moist wound. For wounds with light exudation, moisten the dressing with normal saline solution (0.9%). Secure the dressing with a suitable secondary dressing.

Removal & Change Frequency

CovaWound™ Alginate Ag should be changed at intervals set by the physician in charge, according to the stage of wound healing and depending on the level of exudate. Remove the secondary dressing using existing clinical protocols. Remove any non-gelled CovaWound™ Alginate Ag dressing and rinse off any gel residue that is left in the wound with normal saline solution (0.9%) before wound assessment and applying the new dressing.

Additional Recommended Dressings

May be used as a secondary dressing to ColActive® Plus (Collagen Matrix Dressing) or ColActive® Plus Ag (Collagen Matrix Dressing with Silver).
