<p>There is provided herein a Luer connector for use in a respiratory gas sampling and/or delivery tubing systems, the connector includes a primary Luer male connector, having a form of a tapered cone, comprising a secondary female section extending from a top distal part of the primary Luer male connector back towards a proximal part thereof, wherein the 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) the secondary female section, wherein the first inner fluid flow channel has a diameter of approximately dl, wherein the diameter increases at a connection point between the first inner fluid flow channel and the secondary female section to form a neck N, wherein the internal diameter of the neck N is between dl and d2, wherein the secondary female section has an internal diameter of d2 at a top distal part of the primary Luer male connector, wherein dl is smaller than d2, wherein the primary Luer male connector is configured to mate with a primary Luer 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 the primary Luer female connector, wherein the secondary male section comprises a second inner fluid flow channel extending along the length thereof and having an internal diameter of approximately dl, wherein when the primary Luer male connector and the primary Luer female connector mate with each other, the secondary male section is at least partially inserted into the secondary female section.</p> |
