  • Patent number: 6133995
    Abstract: A particle measuring apparatus includes a characteristic parameter extracting device for extracting a plurality of characteristic parameters from each particle in a sample, and a distribution diagram preparing device for preparing a first distribution diagram on the basis of the extracted characteristic parameters. It further includes a first separating device for separating a cluster including target particles from others on the prepared first distribution diagram. In addition, a discriminating device is included for setting a specified discrimination standard for the separated cluster including the target particles and for judging whether the particles in the cluster are target particles or non-target particles on the basis of the discrimination standard. Finally, a counting device is included for counting the number of the target particles on the basis of a discrimination result of the discriminating device.

  • Patent number: 5831723
    Abstract: A particle analyzer includes a sheath flow cell for converting a particle containing sample into a sample flow, a first light source for illuminating the sample flow by a continuous light, a light detecting element for detecting a light emitted from a particle illuminated by the first light source and for converting the light into a particle signal indicative of a characteristic of the particle, a second light source for illuminating the sample flow by a momentary light, an imaging device for capturing an image of a particle illuminated by the second light source, an analyzing section for performing particle analysis by employing the particle signal and the image of the particle as analysis data for analyzing the particle, and an inhibiting section for inhibiting the analyzing section from employing, as the analysis data, the particle signal obtained when the second light source illuminates the sample flow.

  • Patent number: 5824269
    Abstract: A flowcytometer includes a sheath flow cell for forming a sample stream containing particles; a detector for detecting the particle at a first area to generate a signal representative of the particle; an imaging device for capturing an image of the particle at a second area of the sample stream; a display; a calculator for calculating a plurality of characteristic parameters of each particle; a distribution preparation device for preparing a distribution of the characteristic parameters to display the distribution on the display; a designation device for previously designating a region in the distribution; a region memory for storing the designated region; a decision device for deciding whether the characteristic parameters of the particle detected at the first area by the detection means are located in the designated region stored in the region memory; an image controller for allowing the imaging device to imaging the particle when the characteristic parameters are located in the designated region; an image

  • Patent number: 5679575
    Abstract: The particle measuring apparatus includes a specimen pipetting section for pipetting a specimen liquid, a reagent dispensing section for dispensing a reagent, a mixing section for receiving the specimen liquid supplied by the specimen pipetting section and the reagent dispensed by the reagent dispensing section and a flow cell for receiving the specimen liquid and the reagent transferred from the mixing section and measuring particles therein; the pipet being so constructed as to be positioned in a first state of picking up the specimen liquid as well as in a second state of supplying the specimen liquid into the mixing section, the mixing section being open when the pipet is in the first state, the mixing section being kept closed by the pipet in the second state so that the reagent dispensed by the reagent dispensing section can press and transfer the specimen liquid in the mixing section out toward the particle measuring section.
