  • Patent number: 6867049
    Abstract: The present invention relates to a method and apparatus for analyzing a blood or other biological fluid sample in a quiescent state, whereby particulate constituents of biological samples that contain sparse populations of interesting cellular species can be enumerated and inspected using an optical scanning instrument. Specifically, this invention relates to a method and apparatus for obtaining increased cellular or particulate concentrations within the use of said optical scanning method.
    Type: Grant
    Filed: September 27, 2000
    Date of Patent: March 15, 2005
    Assignee: Becton, Dickinson and Company
    Inventors: Brian G. Scrivens, Dwight Livingston, Robert S. Frank, Klaus W. Berndt
  • Patent number: 6819408
    Abstract: The present invention relates to a method and apparatus for analyzing a blood or other biological fluid sample in a quiescent state without the need for additional diluting reagents or fluid streams passing through the apparatus during the analytic process, whereby particulate constituents of biological samples can be enumerated and inspected using an optical scanning instrument. Specifically, this invention relates to a method and apparatus for obtaining decreased cellular or particulate concentrations within the use of this system.

  • Patent number: 6597450
    Abstract: An apparatus and method employing a plurality of light emitting devices which each can get light through a respective optical fiber toward a respective sample of a plurality of samples in a time-staggered manner. Light is generated in each of the samples at different times consistent with the times at which light is irradiated onto the sample. A single detector is used to detect the lights emitted from the plurality of samples at these different times. A plurality of bifurcated optical cable are coupled to the light emitting devices and single light detector, and the integrated end of each bifurcated cable acts as the light emitting port and light detecting port. Multiple targets can be detected from each of the plurality of samples in the same manner by providing an apparatus and method employing a different plurality of light emitting devices and single detector for each target to be detected.
