Specimen identification and dispensation device and specimen identification and dispensation method

摘要

A specimen identification and dispensation device includes an optical measurement device which is an identification part for measuring and identifying optical information on a specimen by emitting exciting light to the specimen being a measurement target dispersed in a liquid flowing through inside of a capillary, a dispensation part for dispensing the identified specimen into wells being sections to be dispensed through a nozzle, and a concentration adjustment part which adjusts the number of the specimens contained in an aliquot solution to a desired number according to the concentration of a sample liquid and the amount of the aliquot solution. The dispensation part is movable three-dimensionally with respect to the identification part and the nozzle.

主权项

1. A specimen identification and dispensation apparatus that dispenses a target specimen as an aliquot target from specimens, which are measurement targets, dispersed in as sample liquid flowing in a flow passage, comprising:
an optical measurement device that measures light information of the specimen by irradiating exciting light onto the specimen and identifies the specimen as a target specimen based on the light information of the measured specimen; a dispensation target container that receives, from a nozzle, a dispensed aliquot solution in which one or a plurality of target specimens identified by the optical measurement device is dispersed; a supply container from which the specimens dispersed in the sample liquid are provided to the optical measurement device; and a controller that controls a resupply path that supplies a liquid containing the target specimens from the dispensation target container to the supply container as the sample liquid to adjust the number of the target specimens as an aliquot object and the number of non-target specimens contained in the aliquot solution to a desired number, based on a sample liquid concentration that is a concentration of the number of specimens contained in the sample liquid in which the specimens are dispersed and an amount of the aliquot solution, wherein the supply container, the optical measurement device, and the nozzle are serially connected such that fluid flowing from the supply container first passes through the optical measurement device before exiting the nozzle.
