Abstract: A syringe for delivery of a medical liquid to a container has a body with proximal end, a frustoconical distal end, and a cylindrical sidewall extending between the proximal end and the distal end along a longitudinal axis. The syringe includes a nozzle at a distal portion of the frustoconical distal end of the syringe, the nozzle having a throughbore providing fluid communication between an interior volume of the syringe and a medical connector configured to be connected to the nozzle. The nozzle includes a plurality of longitudinal ribs formed on an inner surface of the nozzle. The syringe is designed so that the plurality of longitudinal ribs directs a flow of a medical fluid along an inner surface of the frustoconical distal end and along an interior surface of the cylindrical sidewall of the syringe under a Coandǎ effect. Syringe and connector assemblies and methods for reducing a number of bubbles formed in a medical fluid during a syringe filling procedure are also described.

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 method for controlling fluid ratio accuracy during a dual flow injection with a powered injection system is described. The method includes predicting a first capacitance volume of a first syringe comprising a first medical fluid and a second capacitance volume of a second syringe comprising a second medical fluid with a first capacitance correction factor and a second capacitance correction factor, respectively, selecting a ratio of the first medical fluid and the second medical fluid to be administered to a patient in the dual flow injection, determining a relative acceleration ratio of a first piston of the first syringe and a second piston of a second syringe based on the predicted first capacitance volume and the predicted second capacitance volume, wherein the relative acceleration ratio is selected to maintain the selected ratio of the first medical fluid and the second medical fluid during the dual flow injection, and injecting a mixture of a first medical fluid and a second medical fluid having the selected ratio with the powered injection system.
