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.

Abstract: An automatic analyzer has a washing tank providing water for washing a reagent or sample probe is. The washing water from a washing nozzle spreads from a throttle portion and is divided into right and left flows after colliding with a vent plate provided in an overflow portion of the washing tank. The washing water flows between the vent plate and the inner wall of the overflow portion, and the flows join behind the vent plate. After joining, the washing water flows downward along the vent plate and the inner wall of the overflow portion and then is drained. Because a space is created between the washing water which has collided with the vent plate and the washing water joined behind the vent plate, the washing water is prevented from completely covering the overflow portion, and the airflow can be secured during the drainage.

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.

Abstract: An automatic analyser which is capable of detecting a dispensing abnormality with a high degree of accuracy without causing the decrease in the determination performance or the increase in the calculation amount caused by the configuration balance of the reference database is implemented. A dispensing nozzle of a sample dispensing mechanism sucks the dispensing target, and internal pressure of the dispensing nozzle when ejecting the dispensing target to a reaction container is detected through a pressure sensor. A plurality of feature quantities are extracted from a waveform of the detected pressure, and a determination result is output through a linear combination formula using an optimal coefficient for a determination function that receives a plurality of feature quantities and outputs one value. The determination result indicates whether or not dispensing of the sample dispensing mechanism is performed normally in accordance with the magnitude of the output result of the determination function.
