Abstract: A multi-fluid injector system having a powered injector having a housing enclosing at least one reciprocally operable piston is described. The injector system includes a multi-use disposable set (MUDS) connectable to the powered fluid injector. The MUDS has at least one syringe having a proximal end and a distal end and a plunger reciprocally movable by the at least one piston element within a syringe interior between the proximal end and the distal end; a manifold in fluid communication with the distal end of the at least one syringe; at least one valve in fluid communication with the syringe interior, the at least one valve operable between a filling position for filling the syringe interior with fluid and a delivery position for delivering the fluid from the syringe interior; and at least one connection port in fluid communication with the manifold and the syringe interior when the at least one valve is in the delivery position. The injector system further includes a coupling mechanism for operating the at least one valve between the filling position and the delivery position. Various features of the MUDS assembly and methods of interaction between the injector system and the MUDS assembly are also described.

Abstract: A multi-use disposable set (MUDS) has at least one syringe having a proximal end and a distal end spaced apart from the proximal end along a longitudinal axis. The MUDS further has a plunger reciprocally movable within a syringe interior between the proximal end and the distal end. A manifold is in fluid communication with the distal end of the at least one syringe. At least one valve is in fluid communication with the syringe interior. The at least one valve is operable between a filling position for filling the syringe interior with fluid and a delivery position for delivering the fluid from the syringe interior. At least one connection port is in fluid communication with the manifold and the syringe interior when the at least one valve is in the delivery position. A multi-fluid delivery system having the medical convector and MUDS is also provided. Various features of the MUDS system are also described.

Abstract: A medical connector for providing a sterile connection between a multi-use portion and a single-use portion of a fluid delivery system is provided. The medical connector includes a fluid inlet port configured for removable engagement with a connection port of a multi-use disposable set (MUDS) to establish a fluid connection therewith and a waste outlet port configured for removable engagement with a waste inlet port of the MUDS to establish a fluid connection therewith. A patient fluid line is connected, at a first end, to the fluid inlet port and connected, at a second end, to the waste outlet port. Fluid flow through the patient fluid line is unidirectional from the first end to the second end. The patient fluid line is configured for being disconnected from the waste outlet port for delivering fluid to a patient. A multi-fluid delivery system having the medical connector and MUDS is also provided.

Abstract: A system capable of monitoring a replaceable component is provided. The system includes a controller for controlling operation of the system; programming instructions according to which the system is configured to: accept input of a viable life for the component, calculate an accumulated amount of distress experienced by the component based on each set of previously collected use data associated with each previous use of the component, and determine, based in part on the accumulated amount of distress, a used portion of the viable life that the component has experienced as a result of the previous use(s) thereof and an unused portion of the viable life; and a feedback device configured to provide to an operator of the system an indication of at least one of the unused and used portions of the viable life of the component. Methods of monitoring a replaceable component of a system are also provided.

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.

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.
