Abstract:
1. A Luer connector for use in a respiratory gas sampling and/or delivery tubing systems, the connector comprising: a primary Luer male connector, having a form of a tapered cone, comprising a secondary female section extending from a top distal part of said primary Luer male connector back towards a proximal part thereof, wherein said primary Luer male connector comprises a first inner fluid flow channel extending along its length from a proximal end thereof to and in fluid flow connection with said secondary female section, wherein said first inner fluid flow channel has a diameter of approximately d1, wherein the diameter increases at a connection point between said first inner fluid flow channel and said secondary female section to form a neck N, wherein the internal diameter of said neck N is between d1 and d2, wherein said secondary female section has an internal diameter of d2 at a top distal part of said primary Luer male connector, wherein d1 is smaller than d2, wherein when said primary Luer male connector mates with a primary Luer female connector having a secondary male section, said secondary male section is at least partially inserted into said secondary female section, thereby extending said inner fluid flow channel having diameter d1 throughout said primary Luer male connector and said primary Luer female connector, such that said diameter d1 is constant throughout said primary Luer male connector and said primary Luer female connector.
