  • Publication number: 20200309803
    Abstract: An automatic analysis apparatus of an embodiment includes a holder, a first dispenser, a second dispenser, a detector, a memory, and processing circuitry. The holder movably holds a plurality of reaction vessels. The first dispenser dispenses an analyte into each of the reaction vessels. The second dispenser dispenses a reagent into the reaction vessel. The detector detects light transmitted through the reaction vessel. The memory stores a test order. The processing circuitry controls the holder, the first dispenser, and the second dispenser based on the test order. The processing circuitry determines one of the reaction vessels to be used for measuring the analyte based on the test order, and performs control to collect characteristic data from another of the reaction vessels not used for measuring the analyte while the analyte is measured.

  • Patent number: 9989549
    Abstract: An automatic analyzer that dispenses a sample and a reagent in a reaction cuvette and measures the mixed solution, including a dispensing probe configured to suction the sample from the sample container and to discharge the sample into the reaction cuvette; a detecting unit configured to detect the sample in the sample container by the end part of the dispensing probe contacting the sample; and a washing unit configured to wash a wide range of the external surface containing a broad end part, rather than the end part of the dispensing probe, which keeps the suctioned sample in the sample container in a second downward suction position, rather than a first suction position detected by the detection unit, wherein the washing unit is configured to have a washing tube, wherein the dispensing probe enters into an upper part of the washing tube, and a pump that supplies the washing tube with cleaning liquid and makes the cleaning liquid flow up through the inside of the washing tube.

  • Patent number: 8951470
    Abstract: An autoanalyzer includes a measurement unit which measures a reaction liquid produced by an interaction between a reagent and an examined sample contained in a reaction container, a sample probe which sucks the examined sample from a sample container and discharges the examined sample to the reaction container, a probe elevating arm which elevates the sample probe with respect to the sample container, and a control unit which controls the probe elevating arm so that a speed at which the sample probe enters a liquid surface of the examined sample to perform an n-th suction operation (n?2) of the examined sample is slower than a speed at which the sample probe enters the liquid surface of the examined sample to perform a first suction operation of the examined sample.

  • Patent number: 8852530
    Abstract: An automated analyzer according to an embodiment includes a probe. The probe has a step part configured to be provided between a lower shaft and an upper shaft, and to be formed such that the outer diameter changes. A descending controller lowers the probe from a predefined position that positions the step part above the liquid surface to an operating position that positions the step part below the liquid surface. A ascending controller raises the probe at a high speed from the operating position until immediately before the step part reaches the position of the liquid surface, subsequently raises the probe at a low speed until the step part passes through the liquid surface, and raises the probe at a higher speed than the low speed from immediately after the step part passes through the position of the liquid surface up to the predefined position.
