ABSTRACT:
Disclosed are wound dressings comprising an absorbent pad for receiving and retaining wound fluids sandwiched between first and second outer sheet materials, the first sheet material for placement on the wound being a perforated non-adherent film for preventing the dressing from sticking to the wound, the second sheet material being characterized as being bacteria-impermeable, the absorbent pad being a multilayer structure comprising an inner layer of a low density absorbent material for receiving fluids diffusing to the dressing from the wound and an overlying layer of a high density absorbent material for receiving and retaining wound fluids diffusing through the inner layer in order to inhibit skin maceration due to the wetness of the surface area of the absorbent pad adjacent the wound.
