Specimen processing system

摘要

Disclosed is a specimen processing system that includes means 91 circularly disposed to carry a reaction vessel 2 used for separating and extracting desired substances from a specimen to be processed, a plurality of processing steps, executed as processing progresses along a transport line for the reaction vessel 2 on the transport means 91, for conducting various processes upon the specimen to be processed that is accommodated in the reaction vessel 2, suctioning and discharging means 94 that dispenses the specimen from a specimen container 1 supplied to the system, into the reaction vessel 2, and a filtering vessel section 2b provided as a part of the reaction vessel 2. This system configuration allows realization of a rapid preprocessing system capable of reducing the number of disposable parts of a low carry-over type, suppressing a decrease in cost performance, operating with high collection efficiency, and employing compact devices.

主权项

1. A specimen processing system for separating, purifying, or filtering specimens, the system comprising:
a turntable rotatably driven to transport one or more reaction vessels used for separating and extracting desired substances from a specimen to be processed, a suctioning and discharging mechanism rotatably driven that dispenses the specimen from a specimen container supplied to the processing system into the one or more reaction vessels; and a cup table rotatably driven to transport a plurality of cups, which are receptacles for receiving a solution reacted within the one or more reaction vessels, wherein the cup table and the turntable do not rotate around the same axis, the suctioning and discharging mechanism includes a base, and, at a plurality of different points around the base, the suctioning and discharging mechanism is configured to suction and discharge the specimen to be processed into the one or more reaction vessels, wherein the suctioning and discharging mechanism includes a plurality of nozzles that operate independently of each other on the same axis and which are disposed at the different points around the base, the system further comprising: a dispensing unit where the specimen to be processed that is accommodated in the specimen container is suctioned and discharged into one of the reaction vessels by the suctioning and discharging mechanism, wherein the dispensing unit includes a specimen container supply line that includes a belt conveyor to supply the specimen accommodated in the specimen container to the turntable to be suctioned by the suctioning and discharging mechanism; a hemolyzing unit which hemolyzes the specimen dispensed into the one of the reaction vessels; and a protein precipitating unit which precipitates proteins in the hemolyzed specimen in the one of the reaction vessels, wherein the dispensing unit, the hemolyzing unit, and the protein precipitating unit are arranged along the turntable, wherein the hemolyzing unit includes:
a specimen container collection line that includes a belt conveyor to carry the specimen container from the turntable to a specimen container collection unit; anda hemolyzing solution injector to inject a hemolyzing solution into the one of the reaction vessels, and wherein the protein precipitating unit includes:
a protein-precipitating solution injector to inject a protein-precipitating solution into the one of the reaction vessels.
