A wound-healing and hemostatic sponge of squid ink polysaccharide/chitosan, a preparation method and use thereof are provided. The sponge comprises squid ink polysaccharide and chitosan as carriers and calcium chloride as an initiator for blood coagulation, and the wound-healing and hemostatic sponge of squid ink polysaccharide/chitosan is achieved via a lyophilization technology. Particularly, the preparation method comprises slowly adding a squid ink polysaccharide solution to a chitosan solution to form a uniformly mixed solution, adding a calcium chloride solution to the uniformly mixed solution, forming a gel followed by the gel being frozen and then lyophilized, and achieving the product. The wound-healing and hemostatic sponge has a good absorbing-errhysis effect, a good pro-coagulant effect, fast hemostasis and a complete hemostatic effect, without secondary re-hemorrhage. Moreover, the wound-healing and hemostatic sponge can promote wound healing, re-epithelialization and repair of epidermis and dermis, with strong wound-healing ability, good biocompatibility, weak toxic side effects and irritation, belonging to a novel wound-healing and hemostatic material. Moreover, the preparation method is reliable, fast, and low cost. |
