View of an intravenous drip bag

Intravenous drip bag. View of an intravenous (IV) drip bag containing saline and glucose (sugar). When in use, a tube carries the solution into the bloodstream, usually through veins in the forearm. Saline and glucose are used to maintain body fluids in patients who are unable to eat or drink. An intravenous infusion, or drip, may also be used to provide other nutrients, to administer certain drugs, or to replace lost blood and plasma. The rate at which the saline enters the circulation is controlled by an adjustable valve
