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.

1. A fluid path set for use in a fluid delivery system, comprising: a multi-patient use section adapted for connection to a pump device and to a source of injection fluid; anda per-patient use section adapted for removable fluid communication with the multi-patient use section, the per-patient use section comprising a pressure isolation mechanism, wherein the pressure isolation mechanism comprises: 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, a pressure isolation port adapted for connection to a source of medical fluid via the multi-patient use section, a lumen connecting the first port and the second port, and 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 in the lumen reaches a predetermined pressure level sufficient to overcome a biasing force applied to the valve member. 2. The fluid path set of claim 1, wherein the multi-patient use section further comprises a multi-position valve adapted to selectively isolate the pump device, the source of the injection fluid, and the per-patient use section. 3. The fluid path set of claim 1, further comprising a pressure transducer associated with the pressure isolation port. 4. The fluid path set of claim 1, wherein the multi-patient use section further comprises an intervening drip chamber between the source of medical fluid and the pressure isolation port. 5. The fluid path set of claim 1, wherein the multi-patient use section is connectable to the per-patient use section by a pair of connectors. 6. The fluid path set of claim 1, wherein the lumen is in fluid communication with an automated or a manual valve having a waste port. 7. The fluid path set of claim 1, further comprising a spike for connecting the multi-patient use section with the source of the injection fluid. 8. The fluid path set of claim 1, wherein the valve member comprises a spring that applies the biasing force to maintain the valve member in the normally open position. 9. The fluid path set of claim 1, wherein the valve member comprises a sealing portion for sealing the pressure isolation port when the valve member is in the closed position. 10. The fluid path set of claim 9, further comprising a sealing seat that contacts the sealing portion of the valve member when the valve member is in the closed position. 11. The fluid path set of claim 1, wherein the valve member is linearly movable between the normally open position and the closed position. 12. The fluid path set of claim 1, wherein, in the normally open position, the pressure isolation mechanism is configured for permitting fluid flow through the lumen and permitting monitoring of a blood pressure of the patient. 13. A pressure isolation mechanism, comprising: a housing defining a lumen with a first port, a second port, and a pressure isolation port; anda valve member disposed within the housing, the 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 in the lumen reaches a predetermined pressure level sufficient to overcome a biasing force applied to the valve member. 14. The pressure isolation mechanism of claim 13, further comprising a pressure transducer associated with the pressure isolation port. 15. The pressure isolation mechanism of claim 13, wherein the lumen is in fluid communication with an automated or a manual valve having a waste port. 16. The pressure isolation mechanism of claim 13, wherein the valve member comprises a spring that applies the biasing force to maintain the valve member in the normally open position. 17. The pressure isolation mechanism of claim 13, wherein the valve member comprises a sealing portion for sealing the pressure isolation port when the valve member is in the closed position. 18. The pressure isolation mechanism of claim 17, wherein the housing comprises a sealing seat that contacts the sealing portion of the valve member when the valve member is in the closed position. 19. The pressure isolation mechanism of claim 13, wherein the valve member is linearly movable between the normally open position and the closed position. 20. The pressure isolation mechanism of claim 13, wherein, in the normally open position, the pressure isolation mechanism is configured for permitting fluid flow through the lumen and permitting monitoring of a patient's blood pressure.
