摘要：
A tracheostomy assembly has an obturator 2 with two resilient catches 30 at its machine end extending along the outside of a coupling 12 on the machine end of the tracheostomy tube 1 and engaging lips 14 on the coupling. This prevents the obturator 2 being displaced rearwardly. The obturator 2 can be disengaged from the tube 1 by twisting it relative to the tube.
