Stopcock apparatus for angiography injector fluid paths

A fluid delivery system comprising:

• at least one powered injector;
• at least one syringe;
• at least one air detector;
• a valve assembly;
• at least one controller in electrical communication with the at least one air detector, wherein the at least one controller is configured for controlling fluid flow through the valve assembly;
• and
• a patient line,
• a bulk fluid source,
• wherein the valve assembly comprises:
• a valve housing;
• a first port in fluid communication with the at least one powered injector, a second port, a third port, and a fourth port;
• a fifth port in fluid communication with the bulk fluid source;
• a fluid path length having a proximal end in fluid communication with the second port and a distal end in fluid communication with the third port;
• and
• a valve element defining a first valve fluid path and a second valve fluid path,
• wherein the patient line is in fluid communication with the fourth port,
• wherein the first valve fluid path provides fluid communication between the first port and the second port in a delivery position of the valve housing relative to the valve element,
• wherein the second valve fluid path provides fluid communication between the third port and the fourth port in the delivery position,
• wherein the third port is isolated from the fourth port in a stop position of the valve housing relative to the valve element, and
• wherein the first valve fluid path provides fluid communication between the first port and the fifth port when in a fill position of the valve housing relative to the valve element.
