A tracheostomy system includes an outer multi-layered tube, which can be expanded or allowed to contract as necessary in order to receive various sizes of cannula tubes. A dilator is used to initially insert the outer tracheostomy tube into the tracheostoma. After the initial installation dilator is removed, various sizes of dilators having a cannula mounted about them can be inserted into the outer tracheostomy tube. The multilayered tube will then expand in response to insertion of the various sizes of dilator cannula assembly being placed. When the dilator is removed the cannula tube will remain in place to maintain the desired diameter tracheostomy tube. This provides a means in which the diameter of the tube can be changed without having to actually remove and reinsert a different tube.

A coupling for connecting an air supply to a respiratory support device has a latching mechanism which prevents the coupling from inadvertently axially displacing from the respiratory support device after they have been mated in a pneumatically discrete path. Non-axial forces are used to disengage the coupling from the respiratory support device. The coupling may include a trailing end adapter which permits rotation of the coupling relative to the air supply rather than to the respiratory support device.

A coupling for connecting a ventilator tube to a tracheotomy tube has a latching mechanism which prevents the coupling from axially displacing a tapered tubular extension of the tracheotomy tube after they have been mated in a pneumatically discrete path. For use with known adult tracheotomy tubes which have inner and outer cannulas, the latching mechanism engages the coupling with the leading end of the outer cannula collar with the inner cannula collar sandwiched therebetween. For use with known one piece children's tracheotomy tubes, the latching mechanism is a clamshell contoured to concentrically grip the tapered tubular extension of the tracheotomy tube. Interlocking the coupling and the tracheotomy tube prevents them from inadvertently axially displacing from each other. Non-axial force disengages the coupling from the tracheotomy tube so that the coupling can be axially displaced without exertion of excessive axial force on the system and the patient.
