A wound plaster, often referred to as a band-aid, is a medical adhesive strip designed to cover and protect minor cuts, abrasions, or scrapes on the skin. It typically consists of a soft, absorbent pad in the center that soaks up any exudate and adhesive edges that secure the plaster in place. Wound plasters come in various shapes and sizes, suitable for different body parts. Some may feature waterproof materials to keep the wound dry during activities like bathing or swimming. Special formulations may include antiseptic properties to prevent infection, making them ideal for first aid kits.
