There are a large number of different types of adhesive foam wound dressing, mainly because one of the most difficult tasks in wound management is controlling exudation. Different types of absorptive dressings work in different ways. For example, the wound may be flat or a cavity, which needs to be lightly filled with an absorptive primary dressing and then covered with another absorptive auxiliary dressing.
If the absorbent dressing does not contain exudates, moisture can cause skin maceration. Foam adhesive dressing absorb exudate-some fluids lock in the core of the dressing, while others become gelatinous foams. Most foam dressings can use framed or borderless adhesives.
Adhesive foam dressing are sheet and other shaped foamed polymer solutions with small, open pores that can hold liquid. They can be impregnated or layered with other materials. Absorptive capacity depends on thickness and composition. The area in contact with the wound surface is non-adhesive Easy-to-remove, clear film coating with adhesive bezel and / or acting as a bacterial barrier.
