Fluid delivery system having pump systems, check valves and a removable patient interface

A fluid delivery system comprising:

• an injector system;
• a first syringe connected to the injector system and operable to be filled with sufficient injection fluid for at least one injection procedure;
• a second syringe connected to the injector system and operable to be filled with sufficient injection fluid for at least one injection procedure;
• a patient interface in removable fluid connection with the first and second syringes;
• a fluid path adapted to be placed in fluid connection between the first and second syringes and the patient interface, the fluid path comprising a housing member defining a first inlet, a second inlet and an outlet, the first and second syringes being in fluid connection with the respective first and second inlets of the housing member and the patient interface being in removable fluid connection with the outlet of the housing member;
• a first check valve in fluid connection between an outlet of the first syringe and the first inlet of the housing member;
• a second check valve in fluid connection between an outlet of the second syringe and the second inlet of the housing member;
• a first fluid container in fluid connection with the first syringe;
• and
• a second fluid container in fluid connection with the second syringe.

A fluid delivery system comprising:

• a first pump system operable to deliver sufficient injection fluid for at least one injection procedure;
• a second pump system operable to deliver sufficient injection fluid for at least one injection procedure;
• a patient interface in removable fluid connection with the first and second pump systems;
• and
• a fluid path in fluid connection between the first and second pump systems and the patient interface, the fluid path comprising a housing member, a first check valve and a second check valve, the housing member defining a first inlet, a second inlet and an outlet, the first and second pump systems being in fluid connection with the respective first and second inlets of the housing member and the patient interface being in removable fluid connection with the outlet of the housing member, the first check valve being in fluid connection between an outlet of the first pump system and the first inlet of the housing member, and the second check valve being in fluid connection between an outlet of the second pump system and the second inlet of the housing member.
