Medico-surgical tube with sealing cuff and a suction lumen at the top of the cuff

摘要

A cuffed tracheal tube has a suction lumen extending along the tube and opening through a suction aperture immediately adjacent the upper, proximal end of the cuff. The inflatable cuff is attached to the external surface of the tube by collars. The proximal collar is everted within the inflatable portion of the cuff 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.
