Abstract

The purpose of the present invention is to provide: a hemostatic material which eliminates the risks characteristic of conventional chitosan-derived products such as endotoxin contamination and triggering of shellfish allergy, can be safely used on more people, and has antibiotic properties and hemostatic effects that widely-used hydrogels do not have; and a wound dressing material containing thesame. Provided are a hemostatic agent containing a cationized cellulose and a wound dressing material containing the same. At least one hydroxyl group of the cationized cellulose is modified with -R2-N+(R3)(R4)(R5).X-, and the other hydroxyl groups of the cationized cellulose have -H or -(CH2CH2O)m-H, where R2 is C1-6 alkylene, C2-6 hydroxyalkylene, -(CH2CH2O)l- or a combination thereof, and l is1 or 2, m is 1 or 2, and X- may be an anionic group.

Description

technical field

[0001] The invention relates to a hemostatic material and a wound dressing containing the hemostatic material. Background technique

[0002] As the mechanism of skin wound healing, it is known that (1) after skin injury, platelets gather in the wound to coagulate the blood to stop the bleeding; (2) neutrophils and macrophages gather around the wound to phagocytize and remove necrotic tissue and bacteria ; (3) Fibroblasts gather to shrink the wound; (4) Epidermal cells migrate and gather to epithelialize the wound.

[0003] Wound healing requires such various living cells to gather and function in the wound. In order to heal a wound, a large number of cytokines represented by growth factors induce desired cells to the wound. In order to heal wounds quickly, it is important to maintain an environment in which cells gathered to the wound by cytokines can actively act.

[0004] The idea that the wound should be dried in order to heal the wound has been mainstr...
