| titleOfInvention | Tissue-guided regenerated collagen membrane and preparation method thereof |
| abstract | The invention relates to a tissue-guided regenerated collagen membrane and a preparation method thereof. The preparation method comprises the following steps: swelling the type I collagen in an acetic acid solution, adding sodium chondroitin sulfate, and uniformly stirring to obtain collagen-sodium chondroitin sulfate slurry; drying the collagen-sodium chondroitin sulfate slurry to obtain a dry membrane; mixing the dry membrane with a crosslinking solution, and carrying out crosslinking reaction to obtain a crosslinked collagen membrane; and cleaning the crosslinked collagen membrane, drying for the second time, and then pressing. The preparation method comprises the steps of firstly swelling high-concentration type I collagen in an acetic acid solution, adding sodium chondroitin sulfate, stirring, drying, crosslinking and drying for the second time, wherein the obtained tissue-guided regenerated collagen membrane has excellent mechanical properties, and the pore size and the porosity are favorable for cell growth and repair; in addition, the degradation period is long, and sensitization is not easy. Comprehensive effect and wide applicability. |
