A transport mechanism is disposed in a measuring device used for dispensing biological samples from sample containers configured to contain the biological samples to cuvettes so as to perform a predetermined measurement, and transports a sample rack configured to hold the sample containers. The transport mechanism includes: a table on which the sample rack is provided in plurality and sequentially placed; a container sensor unit configured to identify the sample containers held on the sample rack; and a transport device configured to transport the sample rack holding the sample container identified by the container sensor unit to a dispensing position at which the biological samples are dispensed. The container sensor unit is disposed in the transport device, so that the transport device transports a preceding sample rack while the container sensor unit identifies sample containers held on a subsequent sample rack.

Provided is a connection module with a high degree of freedom for an automatic analyzer which does not depend on a device as a discharge destination. For this purpose, a module to be connected to an automatic analyzer with a rack rotor mechanism includes: a rack discharge mechanism for moving a rack from the rack rotor mechanism to a rotation holder; a rack rotating mechanism for rotating the rack moved to the rotation holder; a conveyor mechanism for transporting the rack from the rack rotating mechanism to a discharge port; and a feeder mechanism for pushing the rack out of the rotation holder to the conveyor mechanism, in which the rack rotating mechanism rotates the rotation holder from a direction parallel to the rack discharge mechanism to a direction parallel to the feeder mechanism and the conveyor mechanism in the selected rotation direction.

An embodiment is a sample analysis system for analyzing a sample that includes at least one test device for analyzing the sample. The system also includes a rack handler operable to move a sample from a first location to a second location along a travel path. The rack handler has a rotation assembly including a) an engagement element for engagement with the sample rack, and b) a motor coupled to the engagement element and is operable to cause rotation of the engagement element. The rotation assembly rotates the sample rack from a first orientation into a second orientation along the travel path when the engagement element engages the sample rack.

This automated analysis device is provided with a plurality of analysis units for analyzing a specimen, a buffer portion which holds a plurality of specimen racks on which are placed specimen containers holding the specimen, a sampler portion which conveys the specimen racks held in the buffer portion to the analysis units, and a control portion which, when performing a process to deliver the specimen racks to the plurality of analysis units, outputs synchronization signals to all the plurality of analysis units, wherein the analysis unit performs a delivery process starting from the synchronization signal, and the analysis unit performs a delivery process starting from the synchronization signal.

The specimen treatment and measurement system 2000 according to the present invention is provided with: a movement stage 2300 having a plurality of treatment lanes for treating specimens in parallel; a consumables supply module 2100 for storing consumables for use in treatment of the specimens, and supplying the consumables to the movement stage 2300; a cartridge supply module 2500 for storing cartridges for use in treatment of the specimens, and supplying the cartridges to the movement stage 2300; and a stage transfer mechanism 2400 for transferring the movement stage 2400 to each module. The cartridge supply module 2500 has a plurality of cartridge cartons for accommodating the cartridges stacked on top of each other, and a push-out mechanism for pushing cartridges out of a cartridge carton to a supply position of the cartridge supply module 2500.

In an automatic analysis device, it is possible during specimen analysis to add/deposit one rack at a time without stopping the analysis, and it is easy to ascertain the analysis sequence. The analyzer has an analysis module, a rack transport module for transporting a specimen rack in which a specimen container storing a specimen is loaded, and a control device. The rack transport module includes a rack supply part for supplying a specimen rack, a rack accommodating part for accommodating a specimen rack, a rack transport line for transporting a specimen rack supplied from the rack supply part, a dispensing line for transporting a specimen rack to the analysis module, and a rack rotor for transferring a specimen rack between the rack transport line and the dispensing line. Operation of the rack supply part for supplying a specimen rack can be stopped independently of the operation of the analysis module.

Disclosed is a reagent container rack used in a specimen analyzer configured to analyze a specimen by use of a reagent. The reagent container rack includes a holder configured to hold a reagent container that contains the reagent; and a lid configured to cover a mouth portion of the reagent container to form an airtight space between the lid and the mouth portion.

An automatic immunoassay system is provided to an automatic immunoassay apparatus and includes a well cartridge provided with a plurality of wells in which a tip mounted on the automatic immunoassay apparatus is sequentially dipped, a cartridge loading mechanism coupled to a lower portion of the well cartridge to couple the well cartridge to the holding plate, a light source unit disposed at one side of the cartridge unit to emit light to the wells, a sensing unit disposed at the other side of the cartridge unit to detect a fluorescence signal generated by light delivered to the wells, and an assay unit analyzing the fluorescence signals detected by the sensing unit.

A sample analyzer, comprising a sample storage region, a sample-drawing channel, and a transport mechanism; the sample storage region being provided with a plurality of storage channels; the sample-drawing channel is provided with a sample-drawing position; the transport mechanism comprises an engagement slot, an actuation mechanism and a first moving mechanism; the engagement slot and the actuation mechanism are fixed on the first moving mechanism, the actuation mechanism comprises an actuator and a second moving mechanism, the actuator is drivable by at least one of the first moving mechanism and the second moving mechanism to realize the movement of the sample holder between the storage channels and the engagement slot; during sample drawing, the first moving mechanism drives the engagement slot to move to the sample-drawing channel, the actuation mechanism enables samples to pass through the sample-drawing position and to make a stop for sample drawing.

A transport system includes a sample rack configured to hold a sample and comprising a notch; a rack storage unit in which the sample rack is stored; a transport path arranged to transport the sample rack moved from the rack storage unit; and a regulating member configured to regulate movement of the sample rack from the rack storage unit toward the transport path, wherein the regulating member is provided at a position corresponding to the notch provided in the sample rack, and enters an interior of the sample rack from the notch and abuts an interior wall of the sample rack as the sample rack moves from the rack storage unit toward the transport path.
