The invention discloses novel wound protective bandage with a water absorption function. The novel wound protective bandage is characterized in that the middle of a protective bandage body is protruded to form a cavity, the edge of an opening of the cavity outwardly extends to form a flange, a circular groove A, a circular groove B and a circular groove C which encircle the cavity are inwardly sequentially formed in the edge of the flange, sponges are adhered in the circular groove A, the circular groove B and the circular groove C, and protrusion directions of the circular groove A, the circular groove B and the circular groove C keep consistent with a protrusion direction of the cavity; an adhesive layer is arranged at the bottom of the flange and is adhered with planar release paper, the size of the planar release paper is matched with that of the protective bandage body, and the shape of the planar release paper is matched with the shape of the protective bandage body. Compared with the prior art, the novel wound protective bandage has the advantages that the novel wound protective bandage is convenient to use and low in cost, and the waterproof performance, the integral fixing performance and the water absorption of the wound protective bandage can be greatly improved owing to the waterproof adhesive layer and the water absorption sponges which are arranged layer upon layer; when the annular adhesive layer A fails in realizing a water blocking effect, a small quantity of water which flows into the sponges can be absorbed by the sponges which are arranged layer upon layer, so that the water can be prevented from flowing into the inner side of the novel wound protective bandage, and the dryness and the sanitation of sterilized cotton yarns can be guaranteed.
