The invention discloses the use of a negatively charged injectable gelatin microsphere-based gel as a hemostatic material. The gelatin microsphere-based gel hemostatic material is made into a gelatin microsphere-based gel through the hydration of gelatin microspheres and water, which gives it injectability and can be injected through a common syringe; At the same time, based on the characteristics of gelatin itself, which absorbs water and can be absorbed and degraded, the injected hemostatic gel absorbs blood and swells and compresses the wound blood vessels, reducing blood flow to achieve hemostasis and hemostasis. The gel does not have to be taken out, thereby reducing the secondary injury to the patient. |
