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.

The injector system further includes a coupling mechanism for operating the at least one valve between the filling position and the delivery position. Various features of the MUDS assembly and methods of interaction between the injector system and the MUDS assembly are also described.

Multiple fluid delivery system with multi-use disposable set and features thereof

A fluid mixing device for mixing a first injection fluid and a second injection fluid includes a first fluid inlet, a second fluid inlet, a mixing chamber in fluid communication with the first and second fluid inlets, and an outlet port in fluid communication with the mixing chamber. The first fluid inlet is configured to conduct the first injection fluid in a first direction and has a first redirecting surface. The second fluid inlet is configured to conduct the second injection fluid in a second direction along a different axis from the first direction and has a second redirecting surface. The mixing chamber is configured to mix the first injection fluid and the second fluid together. The mixture of the first injection fluid and the second injection fluid exits the fluid mixing device via the outlet port.
