The ingredient of alginate medical dressing is alginate, which is a natural polysaccharide carbohydrate extracted from seaweed, which is a kind of natural cellulose. Alginate dressing, a advanced wound dressing, can form a soft gel after contact with wound exudate, providing an ideal moist environment for wound healing, promoting wound healing and relieving wound pain. When the medical alginate dressing is in contact with the wound exudate, sodium alginate is formed through ion exchange, which has the ability to absorb a large amount of liquid, which is 5-7 times that of gauze. Sodium alginate absorbs water until it is saturated. After absorbing exudate, it expands and acts as a gel. The gel is conducive to creating a moist environment for wound healing, and can be completely peeled off without leaving fibers on the wound surface. The alginate dressing releases calcium ions into the wound to induce platelet activation and the production of blood growth factors, which can stop bleeding and accelerate wound healing. The barrier function of dressings to adsorb and block bacteria is to enhance the defense of wounds against pathogenic microorganisms by stimulating the activation of wound macrophages.
