Abstract
The invention concerns an endotracheal tube with a collar. In order to avoid as far as possible the danger of a pulmonary infection caused by microbes introduced along the tube, at least one device with an antimicrobial action is fitted at one or more points (12) on the outer surface of the tube. This device consists preferably of a piece of silver foil, vapor-deposited silver or a silver compound (silver salt), or may also be a length of tubing fitted in the tube.
