Description
A cannula is a fine tube inserted into a vein, usually in the back of your hand or arm, using a small fine needle. The needle is removed and the tube is left inside your vein. The cannula has 1 or more connectors which allow staff to give fluids and medication (drugs) directly into your bloodstream. Sometimes a cannula may be inserted into your foot, leg or other part of your body. A cannula is sometimes called a Venflon.
