Abstract: A fluid control valve for use in a fluid delivery system for delivering fluid to a patient includes a valve body defining an internal chamber, a first inlet port for receiving a first inlet tube, a second inlet port for receiving a second inlet tube, an outlet port, and a sliding valve member slidably disposed in the internal chamber. The first inlet tube defines a first inlet lumen axially aligned with the internal chamber. The second inlet tube defines a second inlet lumen axially aligned with the internal chamber. The sliding valve member includes a first sealing end and second sealing end. The sliding valve member is positionable in a first operating state, a second operating state, and a third operating state based on a flow differential between the first inlet lumen and the second inlet lumen.

Abstract: A fluid injector system for delivering a multi-phase fluid injection to a patient and methods of fluid delivery is disclosed. Methods of creating and using a multi-aspect fluid path impedance model of the injector system are used. Modeling and adjustment of factors that affect impedance and prevent or reduce backflow, reduce the likelihood of fluid flow rate spikes and provide more accurate flow rates and mixing ratios of fluids may be repeated or happen essentially continuously during an injection. The adjustments may be determined before the injection or determined and/or adjusted during the injection. The determination may include sensor feedback commonly used in injectors such as pressure and position feedback as well as other sensors. In all cases, the user can be notified of adjustments through on-screen notices and/or through the recordation of the injection data by a control device of the injector at the conclusion of the injection.

Abstract: A fluid mixing device for mixing a first injection fluid and a second injection fluid includes a first fluid inlet, a second fluid inlet, a mixing chamber in fluid communication with the first and second fluid inlets, and an outlet port in fluid communication with the mixing chamber. The first fluid inlet is configured to conduct the first injection fluid in a first direction and has a first redirecting surface. The second fluid inlet is configured to conduct the second injection fluid in a second direction along a different axis from the first direction and has a second redirecting surface. The mixing chamber is configured to mix the first injection fluid and the second fluid together. The mixture of the first injection fluid and the second injection fluid exits the fluid mixing device via the outlet port.

Abstract: A method of maintaining an overall flow rate during a sequential delivery of at least two fluids to a patient's blood vessel includes delivering at least a first fluid into the patient's blood vessel at a first flow rate, delivering at least a second fluid into the patient's blood vessel at a second flow rate, and adjusting at least one of a first flow profile of the first flow rate and a second flow profile of the second flow rate to dampen a transient increase in the overall flow rate during a transition between delivering one of the first fluid and the second fluid to delivering the other of the first fluid and the second fluid.

Abstract: A fluid injection system including a graphical user interface, a fluid control module operatively connected to the graphical user interface, a monitoring control module provided in at least one of the graphical user interface and the fluid control module, a fluid injector operatively connected to the graphical user interface and the fluid control module, at least one fluid path set in fluid communication with the fluid control module, and a hemodynamic monitoring system operatively connected to the fluid path set and the monitoring control module. The hemodynamic monitoring system may be configured to receive electrical signals regarding pressure waves formed in medical fluid directed through the fluid path set based on a location of the fluid path set in a patient's vasculature, to convert the electrical signals to pressure wave form information, and to send the pressure wave form information to the monitoring control module.

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.
