Needleless connector with compressible valve

A needleless connector comprising:

• a housing having an inner surface defining an internal cavity and a central longitudinal axis, the housing comprising a body section and a base section, the body section comprising a first port, and the base section comprising a valve mount at a top of the base section, an air passage channel, and a second port at a bottom of the base section;
• and
• a compressible valve comprising a head, a flange, and a cylindrical wall extending between the head and the flange, the cylindrical wall forming an interior air space and comprising a first interior dimple and a second interior dimple, the first interior dimple comprising a first longitudinal arcuate shape and a second longitudinal arcuate shape that is different than the first longitudinal arcuate shape, and the second interior dimple comprising a third longitudinal arcuate shape and a fourth longitudinal arcuate shape that is different than the third longitudinal arcuate shape, wherein the cylindrical wall comprises a thickness that decreases along the first and second interior dimples;
• wherein the flange of the compressible valve is coupled to the valve mount of the base section and the cylindrical wall is positioned within the internal cavity of the housing such that a fluid pathway from the first port to the second port is formed between the inner surface of the housing and an outer surface of the compressible valve, and an air flow path from the interior air space to an ambient environment is formed through the air passage channel of the base.
