Chitosan is a natural polysaccharide extracted from marine organisms (such as shrimp shells, crab shells, etc.) or plant sources such as mushrooms. It has good biocompatibility and biodegradability, is not prone to allergic or rejection reactions, and is suitable for medical applications.
The gauze part of chitosan hemostatic gauze is usually made of pure cotton or yarn, ensuring its water absorption and breathability. The gauze is soft and comfortable, can effectively absorb blood and maintain a moist environment on the wound surface, accelerating the wound healing process.
After chitosan is processed, the nano-sized particles can be tightly combined with the gauze fibers to form a chitosan nanofiber film. This nanofiber film has a good hemostatic effect and can quickly cover the wound surface to form a protective layer. At the same time, chitosan has a coagulation effect and can interact with platelets and coagulation factors in the blood to promote platelet aggregation and coagulation processes, thereby accelerating hemostasis.
The method of using chitosan hemostatic gauze is usually to cover the bleeding wound with gauze and fix it with tape or bandage. While covering, the nanoscale chitosan fiber film will come into contact with the wound surface and exert a hemostatic effect. The chitosan nanofiber film can quickly absorb blood when in contact with blood and provide pressure to a certain extent to help control bleeding.
In general, chitosan hemostatic gauze is a safe and effective medical material with the functions of rapid hemostasis, blood coagulation promotion and wound protection. It is often widely used in medical fields such as surgery, trauma, and incision, providing a reliable choice for wound management.
