Abstract
Disclosed embodiments relate to a wound contact layer in the form of a perforated film, possessing one or more of the following functions: speed of kill, sustained kill, broad-spectrum kill against microorganisms, one-piece removal, conformability with a wound surface, compatibility with negative pressure wound treatment, exudate management, autolytic debridement, and self-indicating of changes. The wound contact layer comprises a biocompatible polymeric matrix and, embedded in the matrix, fluid-absorbent particles loaded with therapeutics. The matrix comprises a mixture of an elastomeric composition and a hydrophilic polymer. The film is perforated with an array of holes. A desired loading of therapeutics in the wound contact layer may be tuned by varying the amount of therapeutics loaded within the fluid-absorbent particles, the density of the fluid-absorbent particles within the wound contact layer, the perforation size, and the thickness of the wound contact layer.
