A multi-action wound dressing for accelerated wound healing by means of multi-therapeutic action is disclosed. The dressing comprises a porous sheet (101)； two flexible sheets (102) having a first sheet (103) and a second sheet (104) attached to each other； multichannel conduits (105) or a plurality of single channel conduits； multichannel tubes (106), side adhesive tapes (107) and an optional wound contact layer (108). The porous sheet (101) includes a top planar surface (201), thickness (202) and a bottom uneven surface (203). The bottom uneven surface (203) lies on the surface of the wound and may have surface patterns (204). The pattern (204) may be wavy patterns and/or any other regular and/or irregular surface protrusion that allow intermediate gaps between wound surface and the bottom surface (203) of the porous sheet through which fluid can flow over the wound surface.
