  • Fluid delivery systems, injector systems and methods of fluid delivery
    Publication number: 20030060704
    Abstract: A fluid delivery system for delivery of an injection fluid to a patient generally includes a pump system to pressurize the injection fluid, a patient interface in removable fluid connection with the pump system, and a connector in fluid connection between the pump system and the patient interface. The pump system is connected to an inlet of the connector, and the patient interface is removably connected to an outlet of the connector. The connector includes a sealing member at least partly disposed within a housing of the connector that is biased to close the outlet when the patient interface is removed.

  • Agglutination detection apparatus
    Patent number: 5256376
    Abstract: A method and apparatus are provided for use with a centrifuge to analyze reactants. The apparatus includes at least one cuvette having at least one chamber. The chamber has a radially outward wall which provides a base upon which reactants can be pelleted when the device is rotated about a centrifugal axis. Each cuvette includes one or more openings for introducing fluids to the cuvette and includes a channel positioned adjacent to the radially outward wall for removing fluids from the chamber. Pressure is applied to the chamber to force fluids therefrom, through the channel. A hold down device is also provided through which fluid and/or pressure may be passed with respect to the cuvette. The invention also provides a method for determining the existence and degree of agglutination of reactants in a first fluid suspension and contained in a single reaction vessel using a photodetector.
