A medical fluid flowline connector comprised of axially aligned relatively rotatable male and female Luer parts and an axially compressible elastomeric seal therebetween includes an elastomeric stopper in the female Luer, the stopper having a swabbable end urged outwardly of the female Luer. The stopper is guided on an axially extending elongated flow conducting insert which has an end which contacts a deformable slit in the swabbable end of the stopper to ensure deformation and opening of the slot as a male Luer at the end of a fluid flowline is pushed against the stopper. The stopper skirt is deformed and displaced into annular space between the female Luer and the insert, the stopper having bellows like walls which engage the female Luer and insert.

The invention claimed is: 1. A medical connector having a longitudinal axis and interconnected axially aligned relatively rotatable male and female Luer parts forming a housing whereby relative rotation of said parts opens and closes a fluid flow path through said connector, said parts being configured for connection to external male and female Luer flowlines; a flow conducting insert non-rotatably affixed in said female Luer part, said insert having an internal fluid passageway extending from a first axially aligned end to a second end, said second end being offset from said axis; a compressible seal in said male Luer part, said seal abutting said second end of said insert and having a flow passageway extending between a first axially offset end at said second end of said insert to an axially aligned second end, such that said ends of said flow passageways in abutting ends of said insert and seal may be aligned to open said flow path; and an elastomeric stopper on said insert, said stopper having a swabbable end providing a deformable normally closed opening which may be opened by pushing said swabbable end over said insert by an external male Luer received in said female Luer part, said stopper having an annular axially collapsible skirt engaged with said female Luer part and said insert. 2. The medical connector of claim 1, wherein said first end of said insert is rounded to facilitate opening of said normally closed opening. 3. The medical connector of claim 2, wherein in said insert includes a seat engageable with said second end of said skirt. 4. The medical connector of claim 3, further comprising relatively engageable stop surfaces on said skirt and said female Luer part to axially retain said skirt in said female Luer part with an exterior surface of said end of said stopper flush with a surrounding portion of said female Luer part. 5. The medical connector of claim 4, wherein said skirt has an axially expansible and contractible portion between said annular seat and said stop surface. 6. The medical connector of claim 5, wherein said skirt slidably contacts said female Luer part and said insert. 7. The medical connector of claim 6, wherein said skirt includes a sealing portion which engages said female Luer part and said insert. 8. The medical connector of claim 1, wherein said female and male Luer parts have abutting faces and exposed surfaces adjacent said faces, said exposed surfaces having indicia which may be aligned at full open and closed positions of the connector. 9. The medical connector of claim 8, wherein said abutting faces extend in radial planes. 10. The medical connector of claim 8, further comprising slidably engageable surfaces on said female and male Luer parts defining full open and closed positions of said connector. 11. The medical connector of claim 1, wherein said female Luer part and said seal have abutting radially extending surfaces. 12. The medical connector of claim 11, wherein said insert and said seal have abutting radially extending surfaces. 13. The medical connector of claim 1, wherein said female and male Luer parts are connected by a snap fit. 14. The medical connector of claim 13, wherein said snap fit connection of said male and female Luer parts causes compression of a peripheral portion of said seal. 15. The medical connector of claim 1, wherein said insert and said female Luer part have mating portions of non-circular cross-section for non-rotatably positioning said insert in said female Luer part. 16. The medical connector of claim 1, wherein said seal and said male Luer part have at least one mating groove and rib to non-rotatably position said seal in said male Luer part. 17. The medical connector of claim 1, wherein said female and male Luer parts and said insert are made of polycarbonate and said stopper and said seal are made of silicone. 18. A medical connector having a longitudinal axis and interconnected axially aligned relatively rotatable male and female Luer parts forming a housing whereby relative rotation of said parts opens and closes a fluid flow path through said connector, said parts being configured for connection to external male and female Luer flowlines; a flow conducting insert non-rotatably affixed in said female Luer part, said insert having an internal fluid passageway extending from a first axially aligned end to a second end, said second end being offset from said axis, said insert having an axially compressible section; a compressible seal in said male Luer part, said seal abutting said second end of said insert and having a flow passageway extending between a first axially offset end at said second end of said insert to an axially aligned second end, such that said ends of said flow passageways in abutting ends of said insert and seal may be aligned to open said flow path; and an elastomeric stopper on said insert, said stopper having a swabbable end providing a deformable normally closed opening which may be opened by pushing said swabbable end over said insert by an external male Luer received in said female Luer part. 19. The medical connector of claim 18, wherein said axially compressible section of said insert is corrugated. 20. The medical connector of claim 19 wherein in said insert includes a seat engageable with said second end of said skirt. 21. The medical connector of claim 20, wherein said corrugated section is proximate said seat.
