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 single-use connector configured to be removably connected to a reusable connector includes a hollow, tubular housing having an open proximal side opposite a distal side along a longitudinal length of the housing and at least one guard member connected to the tubular housing. The at least one guard member is configured to transition between an open position, in which the single-use connector can be connected to the reusable connector, and a closed position in which the guard member prevents the single-use connector from being connected to the reusable connector. Disconnecting the single-use connector from the reusable connector causes the at least one guard member to transition from the open position to the closed position. A single-use disposable set (SUDS) including a single-use connector and at least use guard member for preventing reconnection of the connector to a reusable connector or fluid port is also disclosed.

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 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 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 fluid injector system includes a multi-use disposable set (MUDS) connectable to a powered fluid injector. The MUDS includes a syringe having a proximal end and a distal end and a reciprocally movable plunger; a manifold in fluid communication with the distal end of the syringe; a rotatable valve in fluid communication with the syringe interior, the at least rotatable valve operable between a filling position for filling the syringe with fluid and a delivery position for delivering the fluid from the syringe; 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.
