An input portion can select and set an operation of the measurement portion to be performed after the excessive immersion determination portion determines that the immersion is excessive immersion from a plurality of modes. A measurement control portion controls the measurement portion depending on a mode set by the input portion.

A device for storing reagent containers on several planes for an automatic analysis appliance comprises a pipetting device comprising a pipetting needle for pipetting of reagents, a first device comprising a plurality of first receiving positions for reagent containers, wherein the first receiving positions are arranged on a first plane, and a second device comprising a plurality of second receiving positions for reagent containers, wherein the second receiving positions are arranged on a second plane.

There is provided an automated analyzer which has plural liquid tanks connected with a dispensing probe and which can efficiently switch the operative liquid tank according to measurement item. The automated analyzer comprises: a liquid dispenser having a dispensing probe and a pump capable of aspirating and dispensing a liquid from and into an open end of the probe that is at one end thereof, the liquid dispenser being operative to cause the liquid aspirated in the probe from the open end and a probe internal liquid of the probe to be dispensed into aliquot receptacles; an internal liquid supply device having plural liquid tanks in which probe internal liquids corresponding to measurement items are stored, supply tubes for placing the liquid tanks in communication with the other end of the dispensing probe, and a selector valve mounted in front of the supply tubes and operative to selectively place the liquid tanks into communication with the probe, the supply device being operative to supply a probe internal liquid into the dispensing probe from one of the tanks; an input section for entering settings regarding operation of the liquid dispenser; and an operation controller for controlling operation of the liquid dispenser based on inputs from the input section. The analyzer makes measurements of different measurement items by switching the operative liquid tank in communication with the probe via the selector valve being an automatic valve under control of the operation controller.

A rinse mechanism rinses reaction cuvettes with first and second detergents. An R1 reagent pipetting mechanism 8 rinses the reaction cuvettes that have been rinsed by the rinse mechanism with a special detergent. A counting unit counts and stores in a storage unit a use frequency of each reaction cuvette for a specific reagent item. A determining unit determines whether the counted use frequency exceeds a predetermined threshold N1. A control unit controls the R1 reagent pipetting mechanism such that, in a case where the counted use frequency exceeds the predetermined threshold N1, the reaction cuvettes, which have exceeded the predetermined threshold N1, are soaked with the special detergent only for a period equal to or less than a value derived by multiplying a pipetting cycle time, which indicates a period when a sample is pipetted, by the total number of reaction cuvettes and a predetermined integer.

A high-throughput automatic analyzer integrates a biochemical analysis section and a blood coagulation analysis section. The analyzer is capable of achieving a reduction in size, system cost, and lifecycle cost. The automatic analyzer includes: a reaction disk; a first reagent dispensing mechanism that dispenses a reagent to reaction cells on the reaction disk; a photometer that irradiates a reaction solution in the reaction cell with light; a reaction cell cleaning mechanism; a reaction vessel supply unit that supplies a disposable reaction vessel for mixing and reacting a sample and a reagent with each other; a second reagent dispensing mechanism that dispenses a reagent to the disposable reaction vessel; a blood coagulation time measuring section that irradiates a reaction solution in the disposable reaction vessel with light to detect transmitted or scattered light; and a sample dispensing mechanism that dispenses a sample to the reaction cell and the disposable reaction vessel.

An analyzer system for in vitro diagnostics includes a sample handler module having a robot arm that delivers samples from drawers into carriers on a linear synchronous motor automation track. Samples are delivered via the automation track to individual track sections associated with individual analyzer modules. Analyzer modules aspirate sample portions directly from the sample carriers and perform analysis thereon.

The present invention is provided with: an automatic analysis device 200 for performing an analysis process to analyze a specimen that is to be analyzed; a specimen pre-processing module 100 for performing pre-processing to cause the specimen to enter a state in which the analysis process can be performed; a main conveyance line 161 for conveying a specimen container carrier 10 which accommodates the specimen that is to be analyzed and in which at least one specimen container can be mounted; and annular conveyance lines 111, 121, 131, 141, 151, 411 that are disposed adjacent to the main conveyance line 161 and that are moreover disposed so as to be capable of transferring the specimen container carrier 10 to and from the main conveyance line 161, the annular conveyance lines 111, 121, 131, 141, 151, 411 being capable of circulating and conveying the specimen container carrier 10 separately without the use of another conveyance line (e.g., a return line 162). This makes it possible to maintain flexibility in conveyance of specimens while suppressing increases in device surface area.
