  • Patent number: 10288637
    Abstract: A pressure signal process unit acquires data under a predetermined condition and a statistic distance between the acquired data and determination-purpose reference data stored in a storage unit is calculated. It is determined whether or not dispensing is abnormal and whether the determination-purpose reference data is suitable for an abnormality detection function to be properly fulfilled. If the determination-purpose reference data is not suitable for an abnormality detection function to be properly fulfilled, temporary determination-purpose reference data is prepared so as to be compared with the previously acquired data under a predetermined condition. If a difference therebetween is greater than a predetermined threshold value, a possibility that an automatic analyzer may have an abnormal component or that a failure may occur in the automatic analyzer is determined, and the result is transmitted to cause a display device to display an alarm.

  • Patent number: 9897624
    Abstract: An automatic analyzer that accurately detects dispensation abnormality in dispensation conditions with small suction quantities has a statistical distance calculation unit that calculates characteristic variables regarding a sucking operation in the first dispensation and calculates a statistical distance D from reference data to the characteristic variables extracted from a memory. A comparison unit compares the statistical distance D with a preset threshold value stored in memory and if the statistical distance D is less than the preset threshold value, the first discharging operation is performed. A controller judges whether a single-handed judgment based on a dispensation quantity condition of the second or subsequent dispensation is possible or not. If the single-handed judgment is impossible, reference data is selected based on a judgment quantity regarding the first dispensation.
