Luer Connectors

Abstract

Luer connector including a primary Luer male connector having a secondary female section extending from a top distal part of the primary Luer male connector back towards a proximal part thereof, the primary Luer male connector including a first inner fluid flow channel extending from a proximal end thereof to the secondary female section, the primary Luer male connector being configured to mate with a primary Luer female connector having a secondary male section including a second inner fluid flow channel.

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 an 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 inner fluid flow channel has a diameter of approximately d1,   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 of diameter d1 throughout said primary Luer male connector and said primary Luer female connector, such that a laminar flow and an undisturbed waveform is maintained throughout said primary Luer male connector and said primary Luer female connector.   
     
     
         2 . A Luer connector for use in a respiratory gas sampling and/or delivery tubing systems, the connector comprising:
 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 said primary Luer 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 primary Luer female connector; wherein when said primary Luer female connector mates with a primary Luer male connector having a secondary female section, said secondary male section is at least partially inserted into said secondary female section, thereby extending said inner fluid flow channel of diameter d1 throughout said primary Luer female connector and said primary Luer male connector, such that a laminar flow and an undisturbed waveform is maintained throughout said primary Luer female connector and said primary Luer male connector.   
     
     
         3 . The connector of  claim 2 , wherein said secondary male section has a length L, which is higher than E max, wherein E max is the maximal distance formed between the top distal part of primary Luer male connector and the deepest point of primary Luer female connector, when primary Luer male connector and primary Luer female connector are mated. 
     
     
         4 . The connector of  claim 2 , wherein said secondary male section comprises one or more side slits to permit allowance for tolerance. 
     
     
         5 . The connector of  claim 2 , wherein said secondary male section comprises at sealing tip on a top portion thereof. 
     
     
         6 . The connector of  claim 2 , wherein said secondary male section comprises a first conducting material, wherein said first conducting material is configured to close a circuit with a second conducting material positioned on said secondary female section when said primary Luer female connector and said primary Luer male connector are correctly placed with respect to one another. 
     
     
         7 . The connector of  claim 6 , wherein said first conducting material comprises electrode strips. 
     
     
         8 . The connector of  claim 2 , for use in a gas analyzing device.
