Comfeel Plus Ulcer Dresing has the same features as the original Comfeel Hydrocolloid Dressing plus calcium alginate is added to increase absorption. It is ideal for low to moderately exuding chronic wounds and superficial acute wounds in the final stages of wound healing. This hydrocolloid dressing is made of moisture absorbing sodium carboxymethylcellulouse (CMC) particles encapsulated in a synthetic, adhesive/elastomer matrix. When the dressing comes into contact with wound exudate, it forms a viscous gel that absorbs exudate, but does not adhere to the wound. Comfeel also has a semi-permeable top film that keeps bacteria out and is waterproof which does not allow water to enter the wound. Comfeel Ulcer can stay on for up to 7 days depending on wound exudate. Comfeel can be used as a primary dressing as well as a secondary dressing. Available in 7 sizes including Sacral and Buttlery contoured shapes for hard to dress areas.
