An absorbent sac wound dressing comprising a wound-contacting layer covered with tapered pores and the bottom surface of tapered pores contacting a wound area wherein discharged exudate penetrates through, a guiding layer transmitting discharged exudate to an absorbent layer, an absorbent layer absorbing discharged exudate to make fibers expand into the shape of gel, which is effective in preventing from backflow of exudate to a wound area, and a translucent breathing layer having a broad spread of micro pores. The placement of the above layer is one on top of another in order and the peripheral edges are joined together by heat-sealing to form a sac without side escape. More particularly, the certain concentration of water-soluble antimicrobial medicines, enzymes or growth factor agents in a suitable amount are well distributed added in the absorbent layer, which is more effective in controlling a wound infection.
