AUTOMATIC ANALYZER

摘要

The dispensing mechanisms dips a dispensing nozzle in a dispensing target contained in a container 11, 21, and 31, aspirates the dispensing target, and discharges the dispensing target to a reaction container 41. One item of determination-purpose reference data is selected from multiple items of the determination-purpose reference data which is stored in a storage unit 93 and used in determining whether or not the dispensing mechanisms 50, 60, and 70 are abnormal, based on the detection result from a pressure sensor 54 when the dispensing mechanisms 50, 60, and 70 dispense a reference dispensing target configured to contain a known ingredient; and whether or not the dispensing mechanisms 50, 60, and 70 are abnormal is determined, based on the detection result from the pressure sensor 54 and the selected determination-purpose reference data when the dispensing mechanisms 50, 60, and 70 dispense a dispensing target used in analysis.

主权项

1. An automatic analyzer comprising:
a dispensing mechanism that dips a dispensing nozzle in a dispensing target contained in a container, aspirates the dispensing target, and discharges the dispensing target to a reaction container; a pressure sensor that detects pressure inside the dispensing nozzle of the dispensing mechanism; a storage unit that stores multiple items of determination-purpose reference data used in determining whether or not the dispensing mechanism is abnormal; a determination-purpose reference data selection unit that selects one item of the determination-purpose reference data from the multiple items of the determination-purpose reference data stored in the storage unit, based on the detection result from the pressure sensor when the dispensing mechanism dispenses a reference dispensing target configured to contain a known ingredient; and an abnormality determination unit that determines whether or not the dispensing mechanism is abnormal, based on the detection result from the pressure sensor and the determination-purpose reference data when the dispensing mechanism dispenses a dispensing target used in analysis.
