| titleOfInvention | Absorbable gelatin styptic powder and preparation method thereof |
| abstract | The invention provides absorbable gelatin hemostatic powder and a preparation method thereof, and the BET specific surface area of the absorbable gelatin hemostatic powder is 30m 2 /g~70m 2 The preparation process comprises the steps of cross-linking treatment, water absorption swelling, mechanical crushing, freeze drying and secondary crushing of gelatin. The hemostatic powder can be well attached to a wound surface, so that the moisture in blood can be quickly absorbed, and a good hemostatic effect is realized. The preparation method is simple and convenient in process, and further, the cross-linking agent which does not participate in the reaction is adopted, and the operations of mechanical crushing, ultrasonic-centrifugal circulation cleaning or ethanol water solution cleaning are carried out after the gelatin is cross-linked and fully swelled, so that the cross-linking agent is effectively removed, the cross-linking agent is free from residue in the hemostatic powder, the irritant influence on organisms caused by the existence of the cross-linking agent is avoided, the safety of the product is improved, and the preparation method has good popularization and application values. |
