Methods, devices, and systems for coupling fluid lines

A fluid coupling system, comprising:

• a first coupling device with a first body and a second coupling device with a second body;
• the first body having a single port with one opening at a first end, a double port with two openings at a second end, the single port and the double port being interconnected for fluid communication by a branching channel in said body;
• the second body with a single port with one opening at a first end, a double port with two openings at a second end, the single port and the double port being interconnected for fluid communication by a branching channel in said body;
• the first body double port being configured to connect to the second body double port to form a sealed channel connecting the first body single port to the second body single port.

A fluid line coupling device kit, comprising:

• a first coupling device having at least two male and/or female connectors;
• a second coupling device having at least two male and/or female connectors that are configured to sealingly engage with at least two male and/or female connectors of the first coupling device;
• each of the first and second coupling devices being configured such that the every one of the at least two male and/or female connectors is fluidly coupled to a single respective port of said each of the first and second coupling devices;
• each of the first and second coupling devices being configured further such that, when said second coupling device at least two male and/or female connectors are configured to sealingly engage with the at least two male and/or female connectors of the first coupling device, flow from the single respective port of the first coupling device flows through both of the at least two male and/or female connectors of each of the first and second coupling devices to the single respective port of the second coupling device.
