Tubus mit abgedichteter Manschette

摘要

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.
