The present invention relates to a tubus (1) for intubating into the trachea of a patient. Said tubus (1) comprises a central lumen (4) for ventilation or respiration and at least one inflatable cuff (2) which is provided at the outer side of the tubus (1). Said cuff (1) is used for sealing the outer side of the tubus against the wall of the trachea. The outer surface of said cuff (2) is provided with a coating (6) which is more or less free-flowing and/or can swell. The problem of the insufficient sealing is thereby resolved. The cuff (2) is not very sensitive. There is no need for particularly high swelling pressures.
L'invention concerne un tube (1) destiné à être introduit dans la trachée d'un patient. Ce tube comprend une lumière centrale (4), pour permettre la respiration, et au moins un manchon (2) gonflable, placé sur le côté extérieur du tube (1). Ce manchon (2) sert à étanchéifier le côté extérieur du tube vis-à-vis de la paroi de la trachée, et présente, sur sa surface extérieure, un revêtement (6) qui peut gonfler et/ou est coulant de manière limitée. Il est ainsi possible de résoudre le problème posé par une étanchéité insuffisante. Le manchon (2) n'est pas particulièrement sensible et le recours à des pressions de gonflage particulièrement élevées n'est pas nécessaire.
