Novel absorbable hemostatic material

Abstract

The invention relates to a novel absorbable hemostatic material which is easy in preparation method, low in cost and good in hemostatic effect. At present most medical hemostatic materials in China are water-soluble hemostatic gauze, and the gauze does not have anti-inflammatory and anti-bacterial effects when being used for hemostasis, and has the defects that the hemostatic speed is low, the in vivo absorption time is long, an inflammatory reaction is easy to cause and the like, and therefore people turns to hemostatic powder, however, as existing hemostatic powder is complex to prepare, high in price, not ideal in hemostatic effect and the like, the hemostatic powder is not applied as a mainstream hemostatic product. The novel absorbable hemostatic material is a guluronic acid polymer generated by an complexation reaction or crosslinking reaction of a guluronic acid monomer, polyvinyl alcohol, lavender essential oil and clove essential oil. The novel absorbable hemostatic material is good in hemostatic effect, and has the advantages that the hemostatic speed is high, the in vivo absorption time is short, broad-spectrum sterilization and anti-inflammation effects are achieved, wound healing is promoted and the like, and in addition, the novel absorbable hemostatic material is not affected by the size and position of a wound surface, and widely applicable to the fast hemostasis for war wound, trauma and other conditions.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a novel absorbable hemostatic material with simple preparation method, low cost and good hemostatic effect. Background technique [0002] Hemorrhage is the first cause of death in war injuries and the second cause of death in trauma. Hemorrhage is also the main cause of death in the operating room of trauma patients. Rapid and effective control of hemorrhage can significantly reduce the death caused by hemorrhage. At present, most of the medical hemostatic materials in China are water-soluble hemostatic gauze, but gauze has no anti-inflammatory and antibacterial effect, and has defects such as slow hemostasis, long absorption time in the body, and easy to cause inflammatory reactions. Therefore, people turn their attention to another The hemostatic material—hemostatic powder, however, has not been applied as a mainstream hemostatic product due to the complicated preparation, hig...

At present, most of the medical hemostatic materials in China are water-soluble hemostatic gauze, but gauze has no anti-inflammatory and antibacterial effect, and has defects such as slow hemostasis, long absorption time in the body, and easy to cause inflammatory reactions. Therefore, people turn their attention to another Hemostatic material—hemostatic powder, however, due to the complex preparation, high price, and unsatisfactory hemostatic effect of the existing hemostatic powder, it has not been applied as a mainstream hemostatic product.
