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 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 syringe manifold for a fluid injector assembly includes a middle body member defining an upper cavity and a lower cavity, the middle body member defining at least one fluid path in an upper surface of the middle body member and at least one fluid path in a lower surface of the middle body member, the middle body member defining at least two ports extending through the middle body member, the middle body member comprising an outlet for connection of the syringe manifold to at least one fluid delivery device; a lower body member received within the lower cavity of the middle body member, the lower body member comprising at least one connector for connection of the lower body member to a syringe assembly; and an upper body member received within the upper cavity of the middle body member.

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 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 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.
