摘要： A fluid injector system includes at least one syringe configured for injecting medical fluid and a fluid path assembly in fluid communication with the at least one syringe, the fluid path assembly including at least one air detection region. The system includes an air detector configured to detect one or more air bubbles in a fluid path associated with the air detection region, at least one shutoff valve at a distal end of the fluid path assembly, and at least one processor programmed or configured to actuate the shutoff valve in response to the air detector detecting the one or more air bubbles in the fluid path associated with the air detection region to prevent fluid flow out of the fluid path assembly. The fluid path assembly has a length greater than a distance that an air bubble can travel or expand during an actuation time of the shutoff valve.

摘要： A system and method for correcting a volume of fluid delivered by a fluid injector during an injection procedure is described. The method included determining and compensating for a volume factor associated with compliance of the fluid injector system and correcting for the volume by one of over-driving the distance that the drive member travels in a fluid reservoir, under-driving the distance that the drive member travels in the fluid reservoir, or lengthening or shortening a fluid delivery time.

摘要： A fluid injector system includes a control device operatively associated with a first drive component configured to pressurize and inject a first fluid and a second drive component configured to pressurize and inject a second fluid. The control device includes at least one processor programmed or configured to: during a first phase of a multi-phase injection protocol, actuate at least the first drive component to inject the first phase; during the first phase of the injection protocol and prior to transitioning to a second phase of the injection protocol, actuate the second drive component to pressurize the second fluid relative to a pressure of the first fluid; and during the second phase of the injection protocol, actuate the second drive component to inject at least the second fluid so that a desired steady-state ratio of the first fluid and the second fluid in the second phase is reached.

摘要： An engagement mechanism associated with a reciprocally movable piston of a fluid injector is configured for releasably engaging an engagement portion at a proximal end of a rolling diaphragm syringe having a flexible sidewall configured for rolling upon itself when acted upon by the piston. The engagement mechanism has a plurality of engagement elements reversibly and pivotally movable about a pivot pin relative to the engagement portion of the syringe between a first position, where the plurality of engagement elements are disengaged from the engagement portion of the syringe, and a second position, where the plurality of engagement elements are pivotally movable about the pivot pin in a radially inward direction to engage with the engagement portion of the syringe. The engagement mechanism further has a drive mechanism for moving the plurality of engagement elements between the first position and the second position.
