A bandage is a piece of cloth or other material used to bind or wrap a diseased or injured part of the body. Usually shaped as a strip or pad,
bandages are either placed directly against the wound or used to bind a cover to the wound. Can consist of a wide range of materials, sometimes containing medication,
placed directly against the wound. The purposes served by dressings include protecting wounds.
In recent years, there have been tremendous advances in the design and composition of bandages
and dressings. The field is becoming increasingly complex, and there are numerous reports of
health care workers applying inappropriate products.
