An adhesive bandage, commonly known as a band-aid, is a small medical dressing used to cover minor cuts, scrapes, or abrasions. It typically consists of a sterile pad that absorbs blood and protects the wound, attached to a flexible adhesive strip that sticks to the skin. This helps keep the area clean and prevents infection. Adhesive bandages come in various sizes and shapes to accommodate different types of injuries. They are often made from materials like fabric or plastic, and some may have additional features, such as waterproofing or antibacterial properties. These bandages are a staple in first aid kits and are widely used in homes and workplaces.
