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.
Claims6
A wound dressing comprising an absorbent material for receiving and retaining wound fluids sandwiched between opposed first and second outer sheet materials,
- the first sheet material for placement over a 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 material being a multilayer structure comprising first and second absorbent layers, the first layer being a low density absorbent fabric having optimum absorption capacity for receiving wound fluids diffusing from the wound through the first sheet material, the second layer being a high density absorbent fabric exhibiting optimum spreading or wicking characteristics for receiving and retaining wound fluid diffusing through the low density absorbent fabric, whereby to inhibit maceration caused by pooling of wound fluid on the wound surface.
