Abstract: A plunger for use with a syringe has a plunger body with a proximal end, a distal end, and a circumferential sidewall extending between the proximal end and the distal end along a plunger longitudinal axis. The plunger further has at least one resiliently deflectable retaining member having a first segment attached to the plunger body and a second segment protruding toward the distal end of the plunger body and deflectable relative to the first segment. The plunger further has at least one actuation member associated with the at least one resiliently deflectable retaining member. The at least one actuation member interacts with a piston to deflect the at least one resiliently deflectable retaining member upon rotation of the plunger relative to the piston. The plunger is engageable with the piston regardless of a rotational orientation of the piston relative to the plunger.

Abstract: A reader system for reading information on at least one identification tag associated with a syringe connected to a fluid injector has a detector and a background screen spaced apart from the detector such that at least one of the at least one identification tags is positioned in an optical path between the detector and the background screen when the syringe is connected to the fluid injector. The reader system further has an illumination system configured for illuminating at least a portion of the background screen. The detector is configured for detecting and decoding the at least one identification tag. Methods for reading information on at least one identification tag associated with a syringe are also described.

Abstract: A fluid injector system includes at least one injector for pressurizing and delivering at least one fluid from at least one fluid reservoir, at least one fluid path section in fluid communication with the at least one injector and having a predetermined index of refraction, and a first proximal sensor and a first distal sensor arranged along the at least one fluid path section. Each of the first proximal sensor and the first distal sensor includes an emitter configured to emit light through the at least one fluid path section, and a detector configured to receive the light emitted through the at least one fluid path section and generate an electrical signal based on the received light. The fluid injector system further includes at least one processor programmed or configured to determine, based on a difference in the electrical signals generated by the first proximal sensor and the first distal sensor, at least one property of a content of the at least one fluid path section.

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: An injector system for delivering a medical fluid, the injector system including an injector configured to receive at least one syringe, the injector comprising at least one piston for releasably engaging and reciprocally driving a plunger or an end wall of the at least one syringe; and a syringe retaining interface comprising one or more retaining elements configured to engage at least a portion of a distal end portion of the at least one syringe to limit movement of the at least one syringe in a distal direction relative to the injector as the medical fluid is delivered from the reservoir via distal movement of the at least one piston.

Abstract: A fluid injector including an injector housing with at least one syringe port for receiving a syringe, and a locking mechanism associated with the at least one syringe port for securing the syringe within the at least one syringe port. The locking mechanism is configured for engaging at least one syringe retaining member of the syringe to releasably lock the syringe within the at least one syringe port. The at least one syringe retaining member rotationally guides the syringe into self-orienting alignment with the locking mechanism and is rotated by the locking mechanism into fully locked position after axial installation of the syringe into the at least one syringe port. The locking mechanism also axially ejects the syringe from the locking mechanism upon rotation of the syringe during removal.

Abstract: A fluid injector system includes at least one injector for pressurizing and delivering at least one fluid from at least one fluid reservoir, at least one fluid path section providing fluid communication between a bulk fluid reservoir and a syringe connected to the at least one injector, and at least one sensor arranged along the at least one fluid path section. The at least one sensor includes an emitter configured to emit light through the at least one fluid path section, and a detector configured to receive the light emitted through the at least one fluid path section and generate an electrical signal based on at least one property of the received light. The fluid injector system may further include at least one processor programmed or configured to determine, based on the electrical signal generated by the detector, at least one of an identity of the at least one fluid present in the fluid path section, a concentration of the at least one fluid in the fluid path section, and at least one property of the fluid path section.
