  • Automated analyzer
    Patent number: 8257650
    Abstract: An automated analyzer for analyzing patient samples. The analyzer includes a plurality of cuvettes, which allow the samples to be mixed with various reagents. The analyzer includes one or more detectors, including a detector adapted to detect luminescence of the reaction mixture in the cuvettes. The analyzer allows for various diagnostic assays to be performed on a single system, and provides for high-sensitivity analysis at faster speeds.
    Type: Grant
    Filed: January 6, 2010
    Date of Patent: September 4, 2012
    Assignee: Siemens Healthcare Diagnostics Inc.
    Inventors: Allan Tit-Shing Chow, William Jackson Devlin, Sr., Timothy Patrick Evers, David Russell Thompson

  • Method for increasing capacity in an automatic clinical analyzer by using modular reagent delivery means
    Patent number: 7338803
    Abstract: An automatic clinical analyzer in which the number of cuvette ports available for reaction vessels on a reaction carousel are 50% in a configuration using a single reagent storage areas; in a second configuration an additional reagent storage areas is employed and additional ones of the cuvette ports on reaction carousel are utilized, thereby significantly increasing throughput.

  • Method and apparatus for pre-treating samples in an automatic chemical analyzer
    Patent number: 5985672
    Abstract: A pre-processor for use in performing heterogeneous immunoassays on samples for analytes in the sample employing concentrically positioned incubating and processing carousels. A single transfer station permits reaction vessels containing sample and reagents to be moved between the carousels. The samples are separated, washed and mixed on the processing carousel and incubated on the incubating carousel thus speeding up processing throughput.
