Douglas M. Zatezalo has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20040143185
    Abstract: A fluid injection system includes an injector comprising a drive mechanism and an illumination device, a fluid container operably associated with the drive mechanism, and a control device operably associated with the drive mechanism. The control device comprises a computer screen having at least one element affiliated with the illumination device. The illumination device and the at least one element emit light of the same color. Further, a method of operating an injector system providing visual stimuli corresponding to a programmed injection protocol includes perceiving visual stimuli provided by an injector or a control device of the injector system, recognizing a pattern provided by the visual stimuli, correlating the recognized pattern to the programmed injection protocol, determining whether the programmed injection protocol is a desired injection protocol, and initiating the programmed injection protocol, if it is determined that the programmed injection protocol is the desired injection protocol.

  • Publication number: 20030216643
    Abstract: A fluid injection arrangement, particularly involving a systematic fluid injection programming capability, in the context of patient imaging systems, in which phases of contrast medium injection and flushing medium injection can be freely and selectably ordered so as to make available to the operator and patient a vast array of possible protocols than has hitherto been essentially unattainable. Also contemplated is the use of a “hold” phase, involving an indefinite pause between phases of a protocol, in connection with such imaging systems. Further contemplated is the use of a “pause” phase in which a pause of fixed duration is pre-programmed into the protocols of MRI injector systems. Additionally contemplated is an internal stopwatch function operable to measure the duration of contrast medium propagation towards determining a scan delay, or for other purposes where such a function may be of benefit.

  • Patent number: 6643537
    Abstract: A fluid injection arrangement, particularly involving a systematic fluid injection programming capability, in the context of patient imaging systems, in which phases of contrast medium infection and flushing medium injection can be freely and selectably ordered so as to make available to the operator and patient a vast array of possible protocols than has hitherto been essentially unattainable. Also contemplated is the use of a “hold” phase, involving an indefinite pause between phases of a protocol, in connection with such imaging systems. Further contemplated is the use of a “pause” phase in which a pause of fixed duration is pre-programmed into the protocols of MRI Injector systems.
