A **bandage** is a medical accessory used to cover wounds, provide support, or secure medical devices like dressings or splints. It can be made from various materials, including cotton, elastic, or synthetic fabrics, and comes in different forms, such as adhesive strips, gauze rolls, or cohesive wraps. Bandages serve to protect injuries from dirt and bacteria, promote healing, and minimize the risk of further injury. They are commonly used in first aid and medical treatments for cuts, sprains, burns, or fractures. Some bandages also include medicinal properties, like antiseptic ointments, to aid in healing.
