AUTOMATIC ANALYSIS DEVICE

摘要

An automatic analysis device in which a probe is washed in a short period of time and the amount of washing water which may be mixed in at the time of suctioning of a succeeding liquid can be decreased. Washing water is supplied to a throttle portion of a washing tank from a washing nozzle. A reagent probe is inserted into the washing tank. Washing of the outside of the reagent probe, washing of the throttle portion, and a washing operation for the inside of the reagent probe are performed while a lowering operation of the reagent probe is performed. The automatic analysis device is configured to perform a drying operation by using vacuum nozzles even when the reagent probe is lifted, and thus, washing and drying operations of the reagent probe can be sped up and can be performed in a short period of time.

主权项

1. An automatic analysis device comprising:
a probe that suctions a reagent or a sample and discharges the reagent or the sample into a reaction container; a dispensing mechanism that moves the probe vertically and horizontally; a suctioning and discharging mechanism that causes the probe to suction the reagent or the sample and discharges the reagent or the sample into the reaction container; a photometer that analyzes the sample in the reaction container; a throttle portion that forms an opening portion into which the probe is inserted; a washing mechanism that discharges washing water which flows on a top surface of the throttle portion; an overflow portion in which washing water discharged from the washing mechanism flows down by passing through the opening portion without dripping therein; a drying mechanism that is arranged below the throttle portion and performs vacuum suctioning of washing water; and a controller that controls operations of the dispensing mechanism, the suctioning and discharging mechanism, the washing mechanism, and the drying mechanism.
