Intravenous drip bag. Gloved hand holding an intravenous (IV) drip bag containing 0.15% potassium chloride (saline) and 5% glucose. 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 give blood and plasma or to administer certain drugs. The rate at which the saline enters the circulation is controlled by an adjustable valve. Rubber gloves help to maintain a sterile environment.
