  • Patent number: 10532166
    Abstract: A system and method for determining the fill volume of a fluid chamber includes a fluid injector, at least one fluid chamber in fluid communication with the fluid injector, one or more sensors positioned relative to the at least one fluid chamber and configured to detect a position of a liquid-gas interface of the fluid contained in the at least one fluid chamber, and at least one processor in communication with the sensors and the fluid injector, and configured to: determine the position of the liquid-gas interface of the fluid, calculate the volume of fluid in the at least one fluid chamber based on the position of the liquid-gas interface, and at least one of: i) display the volume of the fluid; ii) enable the fluid injector to perform an action; and iii) disable the fluid injector from performing the action.

  • Publication number: 20190307953
    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.

  • Publication number: 20190083699
    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: 20190046719
    Abstract: A fluid injector having at least one injector head with a front end configured to releasably receive the at least one syringe is described. The fluid injector further includes at least one pressure jacket releasably associated with the front end of the at least one injector head for securing the at least one syringe during an injection procedure. A connection mechanism releasably connects the at least one pressure jacket to the front end of the at least one injector head. The connection mechanism includes at least one electromagnet.

  • 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.
