healing process or causing pain to the patient the combination of a primary dressing that requires minimal changes and a secondary dressing that is easy to change and replace reduces wound maintenance costs which benefits patient staff and hospital an example of punctate scarring is illustrated in fig3 the figure shows the skin of a patient whose burn was covered with the ancestor awbat dressing with a fixed porosity of at least 5 5 chronic slow healing wounds require similar treatment as burns in that all necrotic tissue must be removed before closing the wound with a primary dressing in the chronic wound exudate and other fluids are often removed with negative pressure wound therapy npwt a negative pressure above the wound or a positive pressure from the wound causes exudate and other wound fluids to pass through the primary dressing into a secondary dressing the primary dressings currently used during npwt are urethane foam polyvinyl alcohol foam or cotton gauze all require frequent dressing changes and infection complications have been reported when these dressings are not changed frequently the present invention will have two layers of water soluble biologicals first a clotting outer layer containing hypoallergenic bse free usp pharmaceutical grade gelatin this layer contacts the wound first and stimulates initial adherence of the dressing to the cleanly debrided wound the second layer of pure aloe or aloesin pure aloe and bse free gelatin or a mixture of pure aloe bse free gelatin and ecm interact with the wound to stimulate the rate of healing while adherent to the wound the first layer is deposited directly on the nylon side of the u201c variable porosity u201d silicone nylon surface and is stable i e requires 100.
