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.

Abstract: A fluid injector system (1000) is configured to perform an injection protocol. The fluid injector system includes a housing (11) and a controller (900) operatively associated with a user input device (40) and a fluid actuator (16). The controller includes at least one processor programmed or configured to determine an orientation of the housing, receive at least one signal from the user input device, determine a direction of fluid actuation based on the orientation of the housing and the at least one signal, and actuate the fluid actuator in the direction of fluid actuation. The direction of fluid actuation corresponds to at least one of actuating the fluid actuator to inject fluid from a fluid reservoir and actuating the fluid actuator to draw fluid into the fluid reservoir.

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: The fluid delivery system generally includes a source of injection fluid, a pump device a fluid path set disposed between the source of injection fluid and the pump device, and a fluid control device. The fluid path set includes a multi-position valve. The fluid control device is operatively associated with the fluid path set and includes a valve actuator adapted to operate the multi-position valve. The valve actuator is adapted to close the multi-position valve to isolate the pump device from a patient and stop flow of the injection fluid to the patient at substantially any pressure or flow rate generated by the pump device for delivering a sharp bolus of the injection fluid to the patient. The valve actuator is generally adapted to selectively place the pump device in fluid communication with the source of injection fluid for supplying the injection fluid to the pump device and the patient.
