(A) The PWD consists of a transparent polyurethane chamber with an adhesive flexible ring and access port to allow injection of active treatment in liquid or gel and withdrawal of wound fluid. The PWD is impermeable and embossed on the skin-facing side with a pattern of small pyramids that promote even distribution of liquid or hydrogel formulated medications. The PWDs used were 10 cm in diameter. (B) The PWD as applied on the pig. Up to 12 deep partial-thickness burn wounds were created on the dorsum of each pig using a custom burn device to create standardized partial-thickness burns (3 cm in diameter).
