The alginate dressing of algal Shu is extracted from all natural precious brown seaweed.
It is rich in mannose acetaldehyde and calcium ions, through the complete replacement of calcium-sodium ions, the formation of moist gel, at the same time due to the release of calcium ions, as a coagulation factor to participate in hemostasis, speed up the hemostatic speed. Calcium alginate dressing can promote coagulation by releasing calcium ions, causing erythrocyte aggregation and deformation, activating platelets, etc., in addition, its special physical properties also play an important role in the hemostasis process.
Therefore, calcium alginate dressing is an ideal hemostatic material, which has high application value in the field of surgical hemostasis. Alginate dressings can absorb 20 times times their body weight of the liquid, alginate dressing has a good absorption and compliance, a wide range of application, can be used for a variety of wound treatment, such as seepage more containing carrion and necrotic tissue of the whole layer or part of the skin defect wound, including infected wounds and the wound with stealth and/or sinus tract. The gel formed after absorbing the exudate will form a good wet environment in the wound part, and promote the self-soluble debridement of the wound and the growth of granulation tissue. The formation of the gel depends on sufficient fluid, so the alginate dressing cannot be used to ooze fewer wounds and wounds that cover the necrotic tissue of the callus on the surface. Alginate dressings containing silver ions also have a high absorption and anti-infective effect, is very suitable for seepage more infected wounds, such as seepage more infection pressure sores wound.
For shallow wounds, severe seepage of the wound, such as lower limb ulcer, you can use flake dressing, and for cavity hole wound should choose a strip of alginate dressing. For epithelial wounds, alginate dressings are superior to cellulose dressings because they are easier to remove without causing pain. Alginate dressings cannot be used in burn patients above three degrees. Alginate dressings can be used in combination with other dressings, such as water colloid dressings, foam dressings and charcoal (odor control), as well as silver-ion dressings.
There are compound dressings made on the market, but even if they are not, they can be easily prepared on their own in clinical practice.
