A valve member for a connector, the valve member comprising:
- a head portion including a top section defining a first seal portion;
- a body portion extending longitudinally from the head portion and defining second seal portion at a proximal end thereof, wherein the second seal portion is disposed distally to the first seal portion;
- and
- a circumferential lip seal extending radially outward from an outer surface of the head portion, the circumferential lip seal disposed between the first and second seal portions.
A needleless connector, comprising:
- a housing having a proximal end defining an inlet port of the housing, a distal end including a base defining an outlet port of the housing, and an inner surface defining an internal cavity extending between the inlet and outlet ports;
- and
- a resilient valve disposed within at least a portion of the internal cavity and movably retained within the housing, the resilient valve comprising:
- a head portion including a top section and a body portion extending distally from the head portion;
- and
- a circumferential lip seal extending radially outward from an outer surface of the head portion and disposed between the top section and the body portion,
- wherein in an open state of the resilient valve where a gap exists between the inner surface of the housing and the outer surface of the head portion, the circumferential lip seal engages at least a portion of the inner surface of the housing to obstruct fluid from flowing from the internal cavity towards and onto the top section of the head portion.
