  • Patent number: 8518662
    Abstract: A disposable cassette for blood analysis includes a housing having an upper panel and a sampling section having a filling inlet; at least one pair of chambers in a form of depression of the upper panel of the housing and sealed by a diaphragm; portions of the diaphragm over the chambers being flexible; and one or more channels adapted to interconnect the pair of chambers; one of the chambers containing a predetermined amount of a reagent for blood analysis; and a sample outlet disposed next to and connected to the chamber containing the reagent, the sample outlet including an outlet cavity recessed from the upper panel, a divider disposed therein, and a cover covering the outlet cavity; the sample outlet sealing the reagent to the chamber containing the reagent. Further disclosed is the method of using the disposable cassette for measurements of hematology parameters on a blood analyzer.

  • Publication number: 20100159498
    Abstract: A blood analyzer having a blood cell sedimentation control mechanism is disclosed, which includes a cassette receiving interface including a cassette compartment and a blood sensor operable to detect a presence of blood in a disposable cassette removably disposed within the cassette compartment; a system control electrically connected to the blood sensor, and a blood measurement assembly connected to the system control and adapted to connect with the disposable cassette. The system control includes a time recording mechanism and a predetermined sedimentation time control criterion. Further disclosed is a method of controlling blood cell sedimentation during sample preparation process on the blood analyzer.
