Abstract: A fill adapter for delivery of a medical liquid to a container has a body with a distal end, a proximal end, and a central bore extending between the distal end and the proximal end along a longitudinal axis. The central bore has an angled portion at the proximal end of the body such that a diameter of the central portion increases at the angled portion in a direction from the distal end to the proximal end. The fill adapter further has a flow controller disposed within the central bore at a distal end of the angled portion such that a gap is formed between an outer surface of the flow controller and an inner surface of the central bore. The flow controller is shaped to direct liquid flowing through the central bore to flow through the gap and along the angled portion of the central bore under a Coandă effect.

Abstract: A rolling diaphragm syringe includes a proximal end having an end wall, a distal end having an open-ended discharge neck, a sidewall extending along a longitudinal axis, and a piston engagement portion protruding proximally from a central portion of the end wall and configured for engagement with a piston of a fluid injector. The piston engagement portion has a stem with a first end attached to the end wall, a second end extending proximally from the first end, and at least one protrusion that protrudes radially outward. The sidewall is flexible and rolls upon itself when acted upon by the piston such that an outer surface of the sidewall is folded in a radially inward direction as the piston is advanced from the proximal end to the distal end, and unfolded in a radially outward direction as the piston is retracted from the distal end to the proximal end.

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 for conducting a fluid injection procedure comprises: a loading device for filling containers with fluid; an information read/write device operatively associated with the loading device and configured to: read information related to the containers stored on information storage devices associated with the containers and write information related to an injection procedure and/or a patient to the information storage devices; and a fluid injector system configured to receive the containers after filling by the loading device and inject the contents of the containers of fluid into the patient. The loading device is configured to fill the containers with fluid based on the information related to the containers read from the information storage devices. The information read/write device is configured to write information to the information storage device. The fluid injector system is configured to read the information and use this information to program the fluid injector system.

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 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: An apparatus for suspending air bubbles in a fluid path of a fluid injector system includes an internal chamber having a curved interior wall defined within the housing, an inlet fluid pathway in fluid communication with the internal chamber, and an outlet fluid pathway in fluid communication with the internal chamber. The inlet fluid pathway extending into the chamber at a tangent to the curved interior wall, and the outlet fluid pathway spaced from the inlet fluid pathway such that fluid flowing into the internal chamber via the inlet fluid pathway is directed away from the outlet fluid pathway. The internal chamber is configured to create an internal fluid vortex in an injection fluid entering the internal chamber from the inlet fluid pathway, and wherein the internal fluid vortex at least temporarily suspends one or more air bubbles in the fluid in the internal vortex and delays the passage of the one or more air bubbles to the outlet fluid pathway.
