ABSTRACT:
The cuff on the patient end of a tracheal tube is attached at one end to the inside of the tube and at the opposite end to the outside of the tube. The cuff encloses an axial sleeve that is slidably mounted within the patient end of the tube and is urged forwardly by a resilient collar. The sleeve can be retracted by applying vacuum to the cuff and, when released, extends forwards to prevent the cuff occluding the patient end of the tube.
