Abstract: A fluid injector system includes at least one injector for pressurizing and delivering at least one fluid from at least one fluid reservoir, at least one fluid path section providing fluid communication between a bulk fluid reservoir and a syringe connected to the at least one injector, and at least one sensor arranged along the at least one fluid path section. The at least one sensor includes an emitter configured to emit light through the at least one fluid path section, and a detector configured to receive the light emitted through the at least one fluid path section and generate an electrical signal based on at least one property of the received light. The fluid injector system may further include at least one processor programmed or configured to determine, based on the electrical signal generated by the detector, at least one of an identity of the at least one fluid present in the fluid path section, a concentration of the at least one fluid in the fluid path section, and at least one property of the fluid path section.

Abstract: A rolling diaphragm syringe has a proximal end having an end wall, a distal end, and a sidewall extending between the proximal end and the distal end. The rolling diaphragm syringe further has a piston engagement portion protruding proximally from a central portion of the end wall, the piston engagement portion having a central axis, and a plurality of grooves recessed inward relative to an outer surface of the piston engagement portion. The grooves are spaced apart from each other in a direction about the central axis. The piston engagement portion is configured for engagement with at least one engagement element of a piston of a fluid injector at least during movement of the piston in a proximal direction

Abstract: A system capable of monitoring a replaceable component is provided. The system includes a controller for controlling operation of the system; programming instructions according to which the system is configured to: accept input of a viable life for the component, calculate an accumulated amount of distress experienced by the component based on each set of previously collected use data associated with each previous use of the component, and determine, based in part on the accumulated amount of distress, a used portion of the viable life that the component has experienced as a result of the previous use(s) thereof and an unused portion of the viable life; and a feedback device configured to provide to an operator of the system an indication of at least one of the unused and used portions of the viable life of the component. Methods of monitoring a replaceable component of a system are also provided.

Abstract: A cap for intake and delivery of a fluid from a syringe is described. The cap includes an outer cap assembly comprising a fluid inlet path and a fluid outlet path and an inner cap assembly configured for innertion into a fluid nozzle of the syringe and to provide selective fluid communication between an interior of a syringe and the fluid inlet path or the fluid outlet path. The outer cap assembly is slidable relative to the inner cap assembly between a first filling position, where the interior of the syringe is in fluid communication with the fluid inlet path, and a second delivery position, where the interior of the syringe is in fluid communication with the fluid outlet path. The outer cap may further slide, relative to the inner cap assembly, to a third closed position where the interior of the syringe is fluidly isolated from the fluid inlet path and the fluid outlet path. Syringes including the cap are also described.

Abstract: A calibration system for calibrating a pressure output of a fluid injector having a housing configured for connecting to the fluid injector; a drive member engagement portion configured for contacting a drive member of the fluid injector; a compressible member, which may have a known modulus of compression, connected at its proximal end to the drive member engagement portion, wherein the compressible member is compressed with movement of the drive member of the fluid injector between a first, uncompressed position and a second, at least partially compressed position of the fluid injector in a distal direction; and a sensor connected to the compressible member is described. The sensor is configured for measuring at least one of a force imparted by the drive member and a displacement of the drive member when the compressible member is in the second, at least partially compressed position. The system may generate a calibration curve for the drive member of the fluid injector and allow the generation of a fault condition. Methods for calibrating a fluid injector are also described.

Abstract: A fluid injection system and a fluid verification system for determining the operating status of the fluid injection system, for example by confirming that a fluid reservoir, containing a fluid for injection, is fully filled with fluid and has free space (i.e., air) near the distal end thereof when the syringe is provided in an upright position nor contains air bubbles. Imaging processing techniques, methods, and systems are also provided to determine various injection parameters and to verify the type and certain properties of fluid that is present within the fluid reservoir.

Abstract: A method of delivering a multi-phase fluid injection to a patient via a fluid injector comprising two or more syringes includes injecting a first fluid of the fluid injection from at least a first syringe at a first predetermined flow rate, wherein the first fluid has a first viscosity; injecting an initial portion of a second fluid from at least a second syringe at an intermediate flow rate different than a second predetermined flow rate for a specified time, the second fluid having a second viscosity different from the first viscosity; and injecting a remaining portion of the second fluid of the fluid injection at a flow rate at the second predetermined flow rate. A fluid injector system configured for delivering a multi-phase fluid injection is disclosed.
