Alginate Dressings

Alginate Wound Dressings are composed of sodium and calcium fibers which are derived from seaweed. They mold themselves to the shape of the wound so that the wound drainage is properly absorbed. These dressings are known to absorb up to 20 times their own weight. Alginate dressings come in flat versions that can be easily placed on open ulcers and rope versions that can be used to pack the wounds and promote healing by absorbing drainage. At Shop Wound Care, we offer a wide range of calcium alginate dressings and silver alginate dressings from various top-selling manufactures like, Maxorb, Biatain, Tegaderm, etc.

How do Alginate Wound Dressings work?

When first placed on the wound, alginate wound dressings are dry and become larger and more gel-like as they absorb wound exudate. This clears out the wound bed, prevents it from getting dry and protects it from harmful bacteria, lowering the risk of infection. By ensuring that the wound surface remains moist, alginate dressings promote new tissue growth. This encourages natural debridement process that removes the damaged or dead skin and promotes a healthier wound environment that assists in wound healing. The calcium fibers present in alginate dressings help bleeding wounds by stabilizing and slowing the flow of blood.
