The invention provides the application of the collagen sponge in the preparation of the medicine for promoting wound healing and the detection method of the physical and chemical properties thereof. The collagen sponge can promote cell growth and differentiation, can promote the repair of connective tissue, has effective blood coagulation, can promote blood vessel formation, accelerate the growth of granulation tissue, provide rich nutrients for tissue growth, and can heal wounds in advance Time to accelerate the healing of damaged tissue. The physical and chemical property detection method comprises the following steps: (1) physical property detection of collagen sponge, including appearance and surface structure observation of collagen sponge, water absorption capacity, detection of unit volume quality; (2) chemical examination of collagen sponge Property testing, including pH value determination, determination of total protein and hydroxyproline content, determination of residue on ignition, arsenic content, heavy metal content, pH, and easily oxidized. |
