Chitosan hemostatic gauze is a special medical dressing made using chitosan technology, mainly used for hemostasis in first aid and surgery. The following is a detailed description of chitosan hemostatic gauze:

1. Chitosan material: Chitosan is a natural polysaccharide extracted from the shells of crustaceans (such as shrimps and crabs), which has excellent biocompatibility and biodegradability. In the medical field, chitosan is widely used in various hemostatic products to promote blood coagulation and wound healing.
2. Hemostatic mechanism: The main function of chitosan hemostatic gauze is to promote platelet aggregation and accelerate blood coagulation when it comes into contact with blood in wounds or bleeding sites through the characteristics of chitosan. This mechanism can quickly form blood clots and effectively stop blood flow.
3. Water absorption and stability: Hemostatic gauze usually has good water absorption, can quickly absorb surrounding blood, lock it inside the gauze, and prevent blood from flowing out again or contaminating the wound.
4. Application scenarios: Chitosan hemostatic gauze is suitable for various surgical operations, trauma treatment and first aid occasions. It is particularly suitable for treating incisions, lacerations or other wounds that require rapid hemostasis.
5. Applicable people and safety: Chitosan is a material of natural origin. Compared with synthetic hemostatics or other chemical hemostatics, it is safer and has almost no risk of causing allergies or other adverse reactions. Therefore, it is suitable for people of all ages and skin types.
6. Subsequent management and use recommendations: After using chitosan hemostatic gauze, appropriate postoperative management and observation are usually required to ensure effective hemostasis and a good healing process of the wound.

Overall, chitosan hemostatic gauze, through its unique chitosan component, provides a safe, effective and convenient way to deal with various hemostatic needs, and is one of the important medical dressings in modern medical emergency.
