Mechanism of medical dressings



1. Safe and non-toxic: Alginate medical film is a natural polysaccharide carbohydrate extracted from seaweed. It is a kind of natural polymer material, which has no toxicity to human body and can be used safely.

2, high moisture absorption: alginate medical film can absorb 11 times the liquid equivalent to its own weight.

3, hemostasis: alginate medical film contact with wound exudate to release Ca2+, can promote the formation of prothrombin activator, accelerate the process of blood coagulation.

4, gelatinization: absorption of wound exudate, Na+/Ca2+ ion exchange with exudate, forming a stable network of gel on the wound surface. Create a microenvironment (slightly acidic, anaerobic or hypoxic, moderately moist) that is good for tissue growth.

5, promote wound healing: micro-acid, anaerobic or hypoxic, moderately moist wound environment promotes the release of growth factors, stimulates cell proliferation, enhances epidermal cell regeneration and cell movement, and promotes wound healing.

6, antibacterial:

1. Good sealing, so that the wound is isolated from the outside bacteria;

2. The harmful bacteria are fixed inside the fiber, effectively inhibiting the proliferation of harmful bacteria and reducing the chance of contact between the bacteria and the wound;

3, moist, slightly acidic environment is conducive to the role of neutrophils, enhance local bactericidal ability, reduce the incidence of infection.

7. Reduce local pain: The hydrogel formed on the surface effectively protects the nerve endings and avoids external stimuli; it is not easy to adhere to the wound, easy to remove, and reduce wound pain.

8, reduce scar formation: due to no stimulation of the wound surface, no damage, so scar formation.
