  • Patent number: 11141535
    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.

  • Publication number: 20210138148
    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.

  • Publication number: 20200390968
    Abstract: A multi-fluid injector system and methods of operation thereof are presented. One embodiment of such a fluid injector system includes an automatic refill procedure for a fluid injector system comprising a fluid injector and an operably engaged syringe. The procedure includes the step of determining, using an electronic control device operably controlling the fluid injector system, whether a fluid injection procedure involving the syringe is impending. If the electronic control device determines that the fluid injection procedure is not impending, such that the automatic refill will not interfere with the fluid injection procedure, an automatic refill of the syringe is initiated.

  • Publication number: 20200230317
    Abstract: A fluid delivery system and method for determining whether the correct fluid is being drawn into and/or dispensed from a syringe. The system includes a syringe, a fluid injector for drawing fluid into and dispensing fluid from the syringe, one or more sensors adapted to measure a force required to draw the fluid into and/or dispense the fluid from the syringe, a processor in communication with the one or more sensors, and a non-transitory, computer-readable storage medium in operable communication with the processor. The computer-readable storage medium contains one or more programming instructions that, when executed, cause the processor to receive from the one or more sensors one or more measurements of the force required to draw the fluid into and/or dispense the fluid from the syringe and determine from the one or more measurements whether a correct fluid is being drawn into and/or dispensed from the syringe.

  • Publication number: 20050230575
    Abstract: The mobile fluid delivery system includes a mobile pedestal and a fluid delivery superstructure detachably connected to the pedestal. The fluid delivery superstructure includes a pump device and a fluid control device. A fluid path set operatively associates the pump device with the fluid control device. The superstructure is further adapted to detachably connect to a patient examination platform. A rail mount is used to provide the interface between the superstructure and the patient examination platform. The rail mount attaches to a rail of the patient examination platform and includes a main body defining an elongated recess for engaging the rail of the patient examination platform. The superstructure detachably connects to the main body. Locking devices are used to secure the rail mount to the patient examination platform and the superstructure to the rail mount. A spacer may be inserted into the elongated recess to accommodate different sized rails.
