[0002] Existing wound-protecting plasters are composed of a base layer for pasting and fixing and a surface layer for treatment, wherein the surface layer is generally ordinary gauze or gauze soaked in anti-inflammatory liquid medicine. Although this wound-protecting plaster has a certain anti-inflammatory effect, However, the effect cannot meet the requirements, especially for wounds with large wounds and deep wounds. The above-mentioned protective bandages cannot be used at all. Bio-sponge or bio-sponge must be applied to the wound, and then tied tightly with a bandage. It is very difficult to use. inconvenient

Embodiment Construction
[0018] like figure 1 The illustrated embodiment of the present invention includes a bottom layer 1 for pasting and fixing and a surface layer 2 for treatment, wherein the surface layer 2 is a spongy or cotton-like bio-sponge or bio-organism made from suckling pigskin. Cotton, preferably a bioabsorbable hemostatic sponge with a protein content of 97% to 99.5%, and the bioabsorbable hemostatic sponge is produced by the following process:
[0019] 1) Choose healthy, virus-free, strong immunity, transgenic hairless 1.5-month-old thin-skinned suckling pigskin, the protein content in the suckling pigskin is above 98%, and carry out the following procedures in a sterile state;
[0020] 2) Remove the fat and meat layer in the skin through a skin slicer;
[0021] 3) Soak in clarified lime water with a pH of 14 at room temperature for 20 days until the suckling pigskin swells;
[0022] 4) Wash the pigskin with pure distilled water to make it reach PH6.0, and remove impurities in the p...

The present invention relates to a biological wound-protecting plaster, including base layer and surface layer, said surface layer is a biological absorbable hemostatic sponge made from pork skin which is used as raw material, and its protein content is 97%-99.5%. Its production process includes the following steps: 1). removing fat and meat layer from pork skin; 2). soaking it in lime water withpH 13-pH 16; 3). cleaning the soaked pork skin; 4). steaming and boiling it to obtain colloidal liquor; 5). using pure clean distilled water to regulate concentration of colloidal liquor to 2%-5%; 6). microfiltering and remoiving impurity; and 7). spraying, foming and drying so as to obtain the absorbable hemostatic sponge.
Description
1. Technical field [0001] The invention relates to a protective bandage, in particular to a biological protective bandage with a bioabsorbable hemostatic sponge as the surface layer. 2. Background technology [0002] Existing wound-protecting plasters are composed of a base layer for pasting and fixing and a surface layer for treatment, wherein the surface layer is generally ordinary gauze or gauze soaked in anti-inflammatory liquid medicine. Although this wound-protecting plaster has a certain anti-inflammatory effect, However, the effect cannot meet the requirements, especially for wounds with large wounds and deep wounds. The above-mentioned protective bandages cannot be used at all. Bio-sponge or bio-sponge must be applied to the wound, and then tied tightly with a bandage. It is very difficult to use. inconvenient. 3. Contents of the invention [0003] The invention discloses a biological protective bandage that can quickly stop bleeding and promote wound healing and...
