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.

First claim

The invention claimed is:

1. A primary female connector comprising:
one or more threads on an outer surface;
an internal surface having an inner circumference; and
a secondary male section that returns into a void of said primary female connector, said void defined by the internal surface of said primary female connector, such that a proximal end of the secondary male section begins at a deepest point of the void of the primary female connector, and a distal end of the secondary male section is located within the void of said primary female connector;
wherein said secondary male section comprises an inner fluid flow channel extending along the length thereof and having an essentially constant internal diameter throughout said primary female connector; and
wherein said secondary male section of said primary female connector is configured to be at least partially inserted into a primary male connector when the primary female connector and the primary male connector at least partially mate with one another using the one or more threads.

2. The connector of claim 1 , wherein said secondary male section has a length L that is higher than E max, wherein E max is the maximal distance formed between a top distal part of said primary male connector and the deepest point of said primary female connector when said primary female connector and said primary female connector are mated.

3. The connector of claim 1 , wherein the connector is used in a gas analyzing device.

4. The connector of claim 1 , further comprising a first optical element positioned on the secondary male section.

5. The connector of claim 4 , wherein said first optical element comprises at least one light source.

6. The connector of claim 1 , further comprising one or more components positioned on the secondary male section configured to actuate a patient monitor when said primary female connector is connected to said primary male connector.

7. The connector of claim 1 , further comprising one or more components positioned on the secondary male section configured to provide data indicative of a type of patient interface.

8. The connector of claim 1 , wherein inner walls of said secondary male section are essentially parallel to inner walls of said first inner fluid flow channel.

9. The connector of claim 1 , wherein said secondary male section comprises an outer wall, said outer wall being non-tapered.

10. The connector of claim 9 , wherein said outer wall is threaded.

11. A primary female connector comprising:
one or more threads on an outer surface;
an internal surface having an inner circumference; and
a secondary male section that returns into a void of said primary female connector, said void defined by the internal surface of said primary female connector, such that a proximal end of the secondary male section begins at a deepest point of the void of the primary female connector and a distal end of the secondary male section is located within the void of said primary female connector;
wherein said secondary male section comprises an inner fluid flow channel extending along the length thereof;
wherein the secondary male section is configured to be at least partially inserted into a primary male connector when the primary female connector and the primary male connector at least partially mate with one another using the one or more threads; and
wherein said secondary male section comprises one or more side slits to permit allowance for tolerance.
