Ventilator to tracheotomy tube coupling

For connecting a ventilator tube having a connector at a leading end thereof to a tracheotomy tube having an outer cannula and an inner cannula, the inner cannula being inserted into a trailing end of the outer cannula and having a tubular extension on a trailing thereof, a coupling comprising:

• a tubular member;
• means on a trailing end of said tubular member for connecting said trailing end of said tubular member in a pneumatic flow path to the ventilator tube leading end connector;
• means on a leading end of said tubular member for mating said leading end of said tubular member in said pneumatic flow path with the tubular extension of the inner cannula by motion of said mating means in a generally axial direction relative to the tubular extension;
• and
• means on said means for mating for engaging with the outer cannula during mating to prevent said leading end of said tubular member from axially displacing from the tubular extension after mating.
