A feeding tube is a medical device used to provide nutrition to patients who are unable to eat or drink normally. The term 'feeding tube' can refer to three different types of tubes: a STRAW, an alimentary canal, and a closed circuit TV. A STRAW is a thin tube that is inserted into the nose or mouth and used to deliver liquid nutrition directly to the stomach. An alimentary canal is a tube that is surgically inserted into the stomach and used to deliver liquid nutrition directly to the small intestine. A closed circuit TV is a tube that is surgically inserted into the stomach and used to deliver liquid nutrition directly to the large intestine.
