Threaded swivel connector for airway tube

A tracheal tube, comprising:

• an airway tube comprising a proximal end and a distal end;
• a connector coupled to the proximal end of the airway tube, wherein the connector comprises:
• a male connector comprising an interior passage;
• a spigot extending distally from the male connector, wherein the spigot is at least partially inserted into the proximal end of the airway tube;
• and
• a locking nut coupled to the spigot and comprising a plurality of interior threads gripping an exterior surface of the proximal end such that the proximal end is positioned between the locking nut and the spigot,
• wherein the male connector, the spigot, and the locking nut are rotatable independently of each other, and
• wherein a fluid path extends through the male connector and the spigot for delivery of airway gases through the swivel connector and into the airway tube.

A threaded connector for an airway tube for delivery of airway gases to a patient, comprising:

• a male connector, the male connector comprising an interior passage;
• a tapered section extending distally from the male connector;
• an internal bore formed within the tapered section;
• an internal spigot disposed within the internal bore and forming a fluid path with the internal passage, wherein a distal end of the internal spigot extends distally beyond the tapered section;
• and
• a plurality of threads disposed on a surface of the internal bore facing the internal spigot.
