Dependent claims

A connector for use in a respiratory gas sampling and/or delivery tubing systems, the connector comprising:

a primary female connector having a form of a tapered cone, wherein at its deepest point, the tapered cone inverts back into a secondary male section and returns into a void of said primary female connector, wherein said secondary male section comprises an outer wall and an inner wall, said inner wall being non-tapered thereby forming an inner fluid flow channel, of a diameter d1, extending along said secondary male section and along said female connector;
wherein a distal end of said secondary male section is located within the void of said primary female connector, the void being defined by an interior bore of said primary female connector;
wherein said inner fluid flow channel diameter d1 is constant throughout said primary male connector and said primary female connector.
