Abstract
A valve assembly for a fluid injector system includes a valve housing, a first port configured for fluid communication with a fluid injector, a second port, a third port, and a fourth port configured for fluid communication with a patient line. The valve assembly includes an air detection region associated with the first port, 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 fluid path and a second fluid path. The first fluid path provides fluid communication between the first and second ports in a delivery position of the valve housing. The second fluid path provides fluid communication between the third and fourth ports in the delivery position. The third port is isolated from the fourth port in a stop position of the valve housing.
