Abstract: A fluid path set including a multi-patient use section adapted for connection with a pump device and a source of injection fluid, and a per-patient use section adapted for removable fluid communication with the multi-patient use section. The per-patient use section includes a pressure isolation mechanism having a first port adapted for connection to the pump device via the multi-patient use section, a second port adapted for connection to a patient, and a pressure isolation port adapted for connection to a source of medical fluid via the multi-patient use section. The per-patient use section includes a valve member biased to a normally open position permitting fluid communication between the first port, the second port, and the pressure isolation port, and movable to a closed position to close the pressure isolation port when fluid pressure reaches a predetermined pressure level sufficient to overcome a biasing force applied to the valve member.
