An introducer for an endotracheal tube (50) has a bendable rod (10) with a video camera (15) and light source (16) mounted at its patient end (12) and connected by a cable (17) to an electrical connector (2) fixed at the machine end of the rod. The connector (2) has a narrow profile to allow the endotracheal tube (50) to be slid over it. In use, the camera (15) is connected to a video display (4) via a cable (5) and a mating connector (6), the rod (10) is bent to the desired shape and inserted into the trachea. The mating connector (6) is then disconnected to enable the endotracheal tube (50) to be slid to the correct position in the trachea along the rod (10) and over the connector (2) mounted at the machine end of the rod. The rod (10) is then removed to leave the tube (50) in position.
