Medico-surgical tubes

摘要

A cuffed tracheal tube 1 has a suction lumen 14 extending along the tube and opening through a suction aperture 19 immediately adjacent the upper, proximal end of the cuff 12. The inflatable cuff 12 is attached to the external surface of the tube by collars 23 and 24. The proximal collar 24 is everted within the inflatable portion 25 of the cuff 12 so that it does not extend beyond the inflatable portion and so that the maximum amount of secretions can be removed through the suction aperture 19.
