Abstract: The present disclosure provides improved methods for calibrating the zero position of at least one drive member of an injector system is disclosed. Automated methods of position calibration of the drive member of a fluid injector are disclosed. These methods address sources of error in positional accuracy and fluid delivery inaccuracies, such as disposable syringe tolerance and injector wear over time. According to other embodiments of the present disclosure, methods and fluid injector systems for determining and correcting for the amount of slack in a fluid injection apparatus are described. An understanding of the calibration and the amount of slack in a fluid injection system allows a processor to correct for the slack, thereby ensuring more accurate fluid delivery to the patient and more accurate imaging processes.

Abstract: 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.

Abstract: 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.

Abstract: A fluid control valve for use in a fluid delivery system for delivering fluid to a patient includes a valve body defining an internal chamber, a first inlet port for receiving a first inlet tube, a second inlet port for receiving a second inlet tube, an outlet port, and a sliding valve member slidably disposed in the internal chamber. The first inlet tube defines a first inlet lumen axially aligned with the internal chamber. The second inlet tube defines a second inlet lumen axially aligned with the internal chamber. The sliding valve member includes a first sealing end and second sealing end. The sliding valve member is positionable in a first operating state, a second operating state, and a third operating state based on a flow differential between the first inlet lumen and the second inlet lumen.

Abstract: A method of maintaining an overall flow rate during a sequential delivery of at least two fluids to a patient's blood vessel includes delivering at least a first fluid into the patient's blood vessel at a first flow rate, delivering at least a second fluid into the patient's blood vessel at a second flow rate, and adjusting at least one of a first flow profile of the first flow rate and a second flow profile of the second flow rate to dampen a transient increase in the overall flow rate during a transition between delivering one of the first fluid and the second fluid to delivering the other of the first fluid and the second fluid.

Abstract: Provided is a fluid wicking tip. The fluid wicking tipi includes a plurality of drip flanges arranged to wick fluid between narrow spaces defined between any two drip flanges. The narrow spaces are dimensioned to facilitate wicking by capillary action. Also provided is a syringe that includes the fluid wicking tip. Also provided is a modular syringe system that includes a syringe and a sleeve configured to be slidably disposed over the syringe.

Abstract: A fill adapter for delivery of a medical liquid to a container has a body with a distal end, a proximal end, and a central bore extending between the distal end and the proximal end along a longitudinal axis. The central bore has an angled portion at the proximal end of the body such that a diameter of the central portion increases at the angled portion in a direction from the distal end to the proximal end. The fill adapter further has a flow controller disposed within the central bore at a distal end of the angled portion such that a gap is formed between an outer surface of the flow controller and an inner surface of the central bore. The flow controller is shaped to direct liquid flowing through the central bore to flow through the gap and along the angled portion of the central bore under a Coandă effect.

Abstract: A fluid injection system that includes an injector head having a syringe for delivering a fluid to a patient; a mounting structure pivotally connected to the injector head and configured to support the injector head above a surface; and a control system operationally coupled to the injector head for controlling an injection procedure is disclosed. The fluid injection system is provided with various sensors to control various aspects of the fluid injection system, such as the establishment of a reference plane, the determination of a tilt angle of the injector head, and the determination of a temperature of an actuation system of the injector head.
