Intravenous cannulation
I.V. Cannula
An I.V Cannula is a butterfly injection device. The device has a narrow tube for entering the vein, which contains a needle that is used to pierce body tissue. After piercing the body tissue and entering the vein, the needle is removed and only the catheter tube remains in the vein. As a result, if the patient bends his arm, his arteries will not rupture and the patient will feel more comfortable.
