Fluid connector system

A fluid connector system comprising:

• a first valve assembly comprising:
• a housing having a first port, a second port, an inner surface forming a channel that extends between the first and second ports, and a sleeve that extends along and spaced apart from an outer surface of the housing, the sleeve having an inner surface comprising a ridge at a distal end portion of the sleeve and extending in a direction toward the housing;
• and a valve element having a base and a head, wherein the valve element is positioned within the channel such that the head obstructs the channel through the second port of the housing when the first valve assembly is in a closed configuration, and the head is moved away from the second port of the housing, in a direction toward the first port of the housing, to permit a fluid flow through the channel when the first valve assembly is in an open configuration;
• a second valve assembly comprising:
• a body having a first port, a male luer structure forming a second port, and an inner surface forming a channel that extends between the first and second ports, and one or more arm that extends from the body in a direction away from the first port of the body and along the male luer structure, the one or more arm having an outer surface comprising a protrusion at a distal end portion of the one or more arm and extending in a direction away from the outer surface of the body and an inner surface spaced apart from an outer surface of the male luer structure;
• a post positioned in the channel and movable between the first and second ports of the body;
• and a biasing element positioned between the post and the first port of the body, such that the post is urged toward the second port of the body to obstruct the channel through the second port of the body when the second valve assembly is in a closed configuration, and the post is moved away from the second port of the body, in a direction toward the first port of the body, to compress the biasing element and permit a fluid flow through the channel when the second valve assembly is in an open configuration;
• wherein, when the first and second valve assemblies are coupled together, the one or more arm is positioned between the inner surface of the sleeve and the outer surface of the housing, and the protrusion is positioned between the ridge and the second port of the housing, such that engagement of the protrusion against the ridge resists separation of the first and second valve assemblies.
