Connector with seal element and adapted connector parts

A medical fluid line connector comprising:

• a base having a cylindrical neck encircling a cylindrical space;
• a septum coupled to the cylindrical neck to seal the cylindrical space at a first end;
• a bayonet pin extending radially outward from the cylindrical neck;
• and
• a projection extending radially outward from the cylindrical neck, the projection being axially and circumferentially spaced from the bayonet pin,
• wherein the bayonet pin and the projection are arranged such that the bayonet pin slides axially into a proximal end of a first segment of a slot formed in a complementary connector as the projection is axially received by a recess of the complementary connector, and the bayonet pin slides circumferentially within a second segment of the slot as the projection slides circumferentially within the recess,
• wherein the bayonet pin and the projection are arranged such that the projection is circumferentially offset from a recess of a non-complementary connector when the bayonet pin is disposed in a first axially extending segment of a slot of the non-complementary connector such that the projection cannot be received in the recess of the non-complementary connector as the bayonet pin slides axially within the first axially extending segment of the slot, and
• wherein the septum is configured to axially receive a conduit extending from the complementary connector and thereby permit fluid communication between the cylindrical space of the fluid line connector and the conduit of the complementary connector when the bayonet pin slides axially into the proximal end of the first segment of the slot and the projection is axially received by the recess of the complementary connector.

• wherein the slot and the recess are arranged such that a projection of a non-complementary connector is circumferentially offset from the recess when a bayonet pin of the non-complementary connector is disposed in the slot such that the projection cannot be received in the recess as the bayonet pin slides axially within the first segment of the slot, and
• wherein the conduit portion of the second medical fluid line connector is configured to move axially through the septum of the first medical fluid line connector upon sliding the bayonet pin into the proximal end of the first segment of the slot and sliding the projection axially into the recess, and the conduit portion is configured to generate a fluid path between the first and second medical fluid line connectors upon movement of the conduit portion through the septum.

A medical fluid line connector comprising:

• a base;
• a conduit portion having a peripheral sidewall extending axially from the base;
