Abstract: A fluid injector system includes at least one injector for pressurizing and delivering at least one fluid from at least one fluid reservoir, a first flexible tube having a first lumen, a second flexible tube having a second lumen, and a valve assembly configured to selectively and reversibly compress the first flexible tube and the second flexible tube to open and close the first lumen and the second lumen. The valve assembly includes a first anvil moveable between a retracted position in which the first lumen is at least partially pen and an extended position in which the first anvil closes the first lumen, a second anvil moveable between a retracted position in which the second lumen is at least partially open and an extended position in which the second anvil closes the second lumen, and at least one eccentric cam rotatable to move the first anvil and the second anvil between the retracted and extended positions.

Abstract: A system for controlling a fluid injection system is disclosed. The system includes at least one processor programmed or configured to determine at least one characteristic of a power injection protocol, where the at least one characteristic of the power injection protocol is associated with a medical fluid involved in the power injection protocol, determine an estimated value of viscosity of the medical fluid based on the at least one characteristic of the power injection protocol, calculate a hydraulic resistance score based on the estimated value of viscosity of the medical fluid, and determine one or more motor controller gains of a motor of a powered fluid injector in the power injection protocol based on the hydraulic resistance score.

Abstract: An assembly for retaining a pressure jacket (134) and a syringe (132) on a fluid injector, the assembly including a base plate (1902) comprising a body (1904); at least a first retaining arm (1910a) and a second retaining arm (1910b) operatively mounted on the body of the base plate, the first retaining arm having a first retaining surface at a distal end thereof and the second retaining arm having a second retaining surface at a distal end thereof, wherein the first retaining surface and the second retaining surface are configured for abutting a distal surface of at least one of the pressure jacket and the syringe; a linkage assembly operatively connected to at least one of the first retaining arm and the second retaining arm, wherein the linkage assembly is configured to move at least one of the first retaining arm and the second retaining arm between at least a first open position and a closed position.
