Needleless luer activated medical connector

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.

A medical connector having a longitudinal axis and comprising:

• interconnected axially aligned relatively rotatable parts forming a housing with a fluid flow passageway in said housing, said parts being configured for connection to external male and female Luer flowline connectors;
• a compressible seal in said housing having a flow passageway extending from an axially aligned end to an axially offset end whereby relative rotation of said parts opens and closes a fluid flow path through said connector;
• and
• a retrograde flow preventer positioned in said fluid flow path, said preventer having a resilient portion with a normally closed fluid conducting perforation in said resilient portion which opens at fluid delivery pressures exerted on an interior surface of said resilient portion and which remains closed at patient vascular pressures exerted on an exterior surface of said resilient portion.
