A process and device for improved healing of large avulsed or burned tissue which prevents excessive cicatricial, keloid or fibromatoid formation, reduces fluid loss, and increases protection from infection by employing an elastomer matrix; i.e., a thin sheet of elastomer with a plurality of fenestrations, placed on the wound and a bath of oil to cover the matrix. The oil bath is provided by a flexible sealed capsule of thin silicone elastomer, preferably filled with soybean oil that percolates through the walls of the capsule. Enhanced granulation tissue formation is promoted by encapsulation of the wound with the matrix. Granulation tissue engulfs the matrix while the matrix integrity and elastic rigidity acts to reduce scarring. The barrier of the sterile soybean oil bath and the barrier of the elastomer matrix improve antisepsis and acts to reduce loss of body fluids. The matrix encourages the generation of granulation tissue since the matrix appears to the body as a foreign object that the body tries to reject. |
