  • Publication number: 20230119931
    Abstract: A cell washer is disclosed. The cell washer includes a vessel configured to hold cells. The vessel includes an elongated body including an opening, an inner surface, and a pocket defined by a first inner surface portion of the inner surface disposed between and radially outward relative to a second inner surface portion and a third inner surface portion of the inner surface, and a cavity. The vessel also includes an actuating device capable of causing the vessel to spin about an axis.

  • Patent number: 7390662
    Abstract: The present invention relates to a hematology instrument system that discriminates platelets from red blood cells, debris and other particles within a blood sample. The instrument system uses an optical trigger and collects data at optical sensor locations relative to a flow cell-illuminating laser beam's optical axis. An axial sensor measures axial light loss due to a particle in the flow cell's illumination aperture. In addition, the instrument system can include an RF unit generates electrical parameters, such as DC and RF parameters, within the flow cell. Blood specimens can be prepared with and without a sphering agent.

  • Patent number: 6343690
    Abstract: A specimen carrier comprises a unitary structure for receiving and retaining a specimen container in an upright orientation. Such unitary structure is defined by a pedestal having upper and lower platforms connected by a stem. Extending upwardly from the upper platform is a plurality of rigid members which support a plurality of opposing flexible fingers adapted to engage and press upon the side wall of a specimen container received by the carrier. Preferably, the specimen carrier of the invention has a chamber formed therein for housing a pre-programmed, programmable or otherwise radio-frequency (RF) identification tag in the form of an RF transponder. Upon being energized by a suitable RF field provided by an RF reader antenna or sensor positioned adjacent the carrier's intended path of movement, the tag transmits a unique identification code, such code being received by the antenna or sensor and decoded by the reader.
