Abstract: An automatic analysis apparatus analyzing a test specimen held in a reaction vessel on the basis of a property of a mixed liquid of the test specimen and a reagent, includes a plurality of reaction vessels which corresponds to a plurality of measurement channels, respectively, a moving unit which moves the plurality of the reaction vessels then stops them at every analysis recycle, a control unit which controls the dispensing unit so as to aspirate the test specimen during movements of the reaction vessels, infuse the test specimen to one of the plurality of the reaction vessels after the reaction vessels stop, and repeatedly aspirate the test specimen and infuse the test specimen to one or more reaction vessels except the first reaction vessel among the plurality of the reaction vessels during stoppages of the reaction vessels.

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.

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.

Abstract: A clinical laboratory apparatus includes a plurality of reaction cuvettes, a first dispenser, a second dispenser, a controller, and an analyzer. A subject sample and a reagent are mixed in each of the plurality of reaction cuvettes. The first dispenser is configured to dispense the subject sample into each of the plurality of reaction cuvettes. The second dispenser is configured to dispense the reagent into each of the plurality of reaction cuvettes so that the subject sample and the reagent are mixed. The controller is configured to categorize the plurality of reaction cuvettes into at least first and second groups, to designate at least first and second analysis items among two or more analysis items with respect to the subject sample, to control the second dispenser to avoid dispensing the reagent relevant to the first analysis item into the second group of the reaction cuvettes. The analyzer is configured to analyze a mixed result.

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.

Abstract: A specimen is sequentially sampled by a probe, and at least one of the number of times of cleaning and a cleaning time when cleaning the probe is changed based on at least one of the number of times of sampling of the specimen by the probe and a sampling amount of the specimen.
