<p>An endotracheal tube (10) has a tapering end portion formed with a port (18) and defining a small diameter orifice (16). To insert the tube (10), a pilot member such as a fibroptic endoscope is first passed through the body portion (12) and orifice (18) before being negotiated down the patient's tracheo-bronchial tree. The tube (10) is then easily slid down the inserted pilot member which is subsequently withdrawn. Alternative means of locating the end of the endotracheal tube relative to the pilot member and of allowing the passage of gases are disclosed.</p> |
