Abstract
The invention relates to the field of biomedical engineering, and discloses a hemostatic agent for jaw central hemangioma hemorrhage and a preparation method and application thereof. The invention is as follows: chitosan powder and organic weak acid are added into organic alcohol to react, so as to prepare chitosan weak acid salt, and then the chitosan weak acid salt is mixed with carboxymethyl chitosan in proportion to obtain the hemostatic agent of the invention. The hemostatic agent of the invention has good fluidity and plasticity. When applied to the hemostasis of jaw central hemangioma hemorrhage, the hemostatic agent of the invention can quickly reach the point of jaw central hemangioma hemorrhage without any stimulation and damage to the tissue. In addition, the hemostatic agent of the invention can inhibit the growth of bacteria, eliminate cross infection, and is easy to clean and remove. Therefore, the hemostatic agent of the invention can safely and effectively treat the massive hemorrhage of jaw central hemangioma, which is worthy of clinical promotion. At the same time, the hemostatic agent of the invention can also be used for hemostasis of hemorrhage points in tissue cavities with special structures.
