Abstract: A system and method for integrating an additive into a substrate to change the characteristics of the substrate includes a roller to impregnate or integrate the additive into the substrate and a heating element to apply heat and improve adhesion of the additive to the substrate.

Abstract: A medical bandage or dressing, including an absorbent layer with at least one layer of polyurethane foam including a superabsorbent polymer additive. The medical bandage or dressing may include one or more hydrophilic non-woven fabric layers bound to the polyurethane foam and one or more layers of the dressing may be heated and sealed to reduce shedding of the superabsorbent polymer additive as liquid is absorbed by the dressing.

Abstract: A dressing including a top film, an adhesive layer positioned adjacent the top film closer to a user's skin when the bandage is in use, a hydrogel layer including a support layer, below the adhesive layer closer to the user's skin when the bandage is in use, and a lower perforated layer positioned under the hydrogel layer for adhering the bandage to a user's skin. All of the layers may be transparent or at least partially translucent to allow a user to view the user's skin through the bandage. The hydrogel layer provides pressure distribution to reduce stress on the user's skin and reduce the likelihood of pressure ulcers.
