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: A fluid delivery system and method for determining whether the correct fluid is being drawn into and/or dispensed from a syringe. The system includes a syringe, a fluid injector for drawing fluid into and dispensing fluid from the syringe, one or more sensors adapted to measure a force required to draw the fluid into and/or dispense the fluid from the syringe, a processor in communication with the one or more sensors, and a non-transitory, computer-readable storage medium in operable communication with the processor. The computer-readable storage medium contains one or more programming instructions that, when executed, cause the processor to receive from the one or more sensors one or more measurements of the force required to draw the fluid into and/or dispense the fluid from the syringe and determine from the one or more measurements whether a correct fluid is being drawn into and/or dispensed from the syringe.

Abstract: A system for heating a medical fluid has at least one first fluid container for storing the fluid, a fluid injector having at least one second fluid container for receiving the fluid from the at least one first fluid container through a fluid path set, at least one heating element positioned in-line with the fluid path set between the at least one first fluid container and the at least one second fluid container of the fluid injector for heating the fluid to a pre-determined temperature as the fluid flows through at least one fluid path element, and a controller for controlling an output of the at least one heating element based on at least one of a property of the at least one heating element and a property of the fluid flowing through the at least one fluid path element.

Abstract: A rolling diaphragm syringe includes a proximal end having an end wall, a distal end having an open-ended discharge neck, a sidewall extending along a longitudinal axis, and a piston engagement portion protruding proximally from a central portion of the end wall and configured for engagement with a piston of a fluid injector. The piston engagement portion has a stem with a first end attached to the end wall, a second end extending proximally from the first end, and at least one protrusion that protrudes radially outward. The sidewall is flexible and rolls upon itself when acted upon by the piston such that an outer surface of the sidewall is folded in a radially inward direction as the piston is advanced from the proximal end to the distal end, and unfolded in a radially outward direction as the piston is retracted from the distal end to the proximal end.

Abstract: A fluid path connector for a medical fluid delivery system, the fluid path connector including a first connector element comprising a body, a first lumen, a first flexible leg, and a second flexible leg, and a second connector element comprising a body defining an undercut, a second lumen, a channel defined in the body, and at least one sealing element positioned within the channel, in which the first flexible leg comprises a first flange and the second flexible leg comprises a second flange, and in which, upon engagement of the first connector element with the second connector element, the first flange and the second flange engage with the undercut of the body of the second connector element to prevent disengagement of the first connector element and the second connector element.

Abstract: A fluid container having a proximal end having an end wall, a distal end having an open-ended neck, and a sidewall extending between the proximal end and the distal end along a longitudinal axis is described. A localized crystallinity of a polymeric material of the fluid container of at least a first region of the fluid container is greater than a crystallinity of a polymeric material of the fluid container of at least a second region. Examples of fluid containers include medical fluid containers, such as medical bottles and syringes, including rolling diaphragm-type syringes, and commercial beverage containers Articles of manufacturer formed form a polymeric material and having regions with increased localized polymeric crystallinity are also described.

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 Coand{hacek over (a)} 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 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 radially movable 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 engaged 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 medical injector including at least one syringe port for engaging at least one syringe and having a locking mechanism. The locking mechanism enables the syringe to self-align with the syringe port for locking engagement upon insertion of the syringe into the syringe port and to axially eject the syringe from the port upon rotational disengagement of the syringe from the port.
