Abstract
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.
Claims26
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.
An elastomeric stopper having an axially extending skirt which includes a longitudinally expansible and contractible portion and an integrally formed end, said end having a normally closed slit to provide a deformable opening to the interior of said skirt.
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.
