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: A plunger for use with a syringe includes a plunger body defining a central longitudinal axis and having a proximal end, a distal end, and a circumferential sidewall connecting the proximal end and the distal end. The plunger further includes at least one retaining member associated with and extending proximally from the plunger body. The at least one retaining member has a first end connected to the plunger body, a second end proximal to the first end and radially and resiliently deflectable relative to the first end, and at least one catch on the second end. A fluid injector system includes a piston having a plunger engagement mechanism configured for interacting with the at least one retaining element of the plunger to releasably engage the plunger for reciprocally driving the plunger within a barrel of the syringe.

Abstract: A fluid injection system and a fluid verification system for confirming that a syringe, containing a fluid for injection, is fully filled with fluid and neither 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 and systems are also provided to determine various injection parameters and to verify the type and certain properties of fluid that is present within a syringe.

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.
