An automatic analyzing device according to an embodiment of the present disclosure includes a reagent cartridge and processing circuitry. The reagent cartridge includes a storing unit storing therein a reagent, a flow path for dispensing the reagent from the storing unit, and a dispensing mechanism configured to dispense the reagent into a reaction cuvette through the flow path. The processing circuitry is configured to control the dispensing mechanism so as to dispose of the reagent in the flow path.

Automatic analyzing device

An automatic analyzer disclosed herein includes a first calibration curve generator configured to generate a first calibration curve indicating a relationship between a concentration and an absorbance based on a result of an optical measurement of a reaction solution obtained by adding a reagent to a reference sample including a known concentration of an object to be detected; and a corrected calibration curve generator configured to generate, after the first calibration curve is generated, a corrected calibration curve based on a result of an optical measurement of a mixed reaction solution obtained by mixing the reagent and the reference sample or water, or an optical measurement of the reagent, and data relating to the first calibration curve.

Calibration of an automatic analyzer for reagent water evaporation

According to one embodiment, an automatic analyzing apparatus includes a reagent depository, a reagent storage unit and a probe. The reagent depository stores a first reagent vessel. The reagent storage unit is provided separately from the reagent depository and in which a second reagent vessel is placeable. The probe suctions a reagent contained in the first reagent vessel at a first position which is located above the reagent depository, suctions a reagent contained in the second reagent vessel at a second position which is located above the reagent storage unit, and discharges the reagent suctioned from the first reagent vessel or the second reagent vessel into a reaction vessel at a third position.

Automatic analyzing apparatus

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.

Automatic analyzer

In one embodiment, an automatic analysis apparatus includes a nozzle, first and second modifying units, a supply unit and a control unit. The control unit respectively controls the first and second modifying units and the supply unit to perform a first step of producing a first flow path state, a second step of producing a second orifice state and a second flow path state, a third step of producing the first flow path state, and a fourth step of producing a first orifice state. The first flow path state causing a fluid to be discharged from the flow path. The second flow path state causing the fluid to be sucked into the flow path. The first orifice state causing the orifice to be located in the air. The second orifice state causing the orifice to be located in a detergent.

Automatic analysis apparatus

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.
