An endotracheal tube (30) has an inflatable bag (40) towards its patient end for sealing with the inside of the trachea (11). Additionally, the tube (30) has a second, longer bag (50) separately inflatable to a lower pressure than the first bag (40) and such as to extend along the tube (30) from the first bag (40) to and through the vocal chords and larynx (13) and occupy the space between the first bag and the vocal chords (13). The inflated second bag (50) can thus reduce passage of secretions and minimises the space available for them. A suction line (26) extends along the tube (30), opening at a location (27) between, or at the interface between the two bags (40) and (50) so that any body secretions that do pass the second bag can be removed. <IMAGE> |
