Fluid collection systems and methods for collecting fluids

A bodily fluid collection system comprising:

• a hollow tube comprising:
• a tube input configured to connect removably to a fluid supply tube and for receiving a fluid therethrough;
• and
• a tube output configured to output the fluid;
• four valves having flow-on and flow-off states connected to the tube output;
• a first collection container comprising a fluid bag defining a water-tight interior and comprising:
• an input valve for receiving fluid from the tube output;
• and
• an exit valve for allowing fluid to exit the fluid bag when the fluid bag is full;
• a second collection container comprising a fluid bag defining a water-tight interior and comprising:
• an input valve for receiving fluid from the exit valve of the first collection container;
• and
• an exit valve for allowing fluid to exit the fluid bag when the fluid bag is full;
• wherein the system is configured to allow fluid to enter the input valve of the first collection container and, when the first collection container is full, to flow out of the exit valve of the first collection container and into the input valve of the second collection container.
