The lid 29 is provided with an air vent 33, a first shield plate 30 and a second shield plate 31 for preventing spattering of the reagent through the air vent 33 due to a wave motion of the reagent.

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.

An automatic biochemical analyzer, comprises a reaction wheel comprising an inner ring and an outer ring, wherein the reaction wheel is equally divided into multiple cuvette positions along a circumferential direction; the inner ring and the outer ring, respectively, each have a photoelectric detection position, a sample injecting position, a reagent injecting position, a sample stirring position, a reagent stirring position, and a cuvette cleaning position; the photoelectric detection position of the inner ring and the photoelectric detection position of the outer ring have a cuvette position interval of N along a counterclockwise or clockwise direction; and the sample injecting positions, the reagent injecting positions, the sample stirring positions, and the reagent stirring positions of the inner ring and the outer ring, respectively, have a cuvette position interval of M along the same direction, M and N being natural numbers, and the difference between M and N being 0 or 1.

To clean a reagent probe 7a, 8a or a sample probe 11a, 12a with a heated cleaning solution, after a first cleaning solution is caused to overflow from a first cleaning container 23 or a second cleaning container 24, the first cleaning solution is temporarily drawn back into the cleaning-solution heating passage 125 to be heated by the heating mechanism 123. After the heating, the first cleaning solution thus heated is re-supplied to the first cleaning container 23 or the second cleaning container 24. As a result, the cleaning solution heated to clean a dispensing probe can be supplied to a cleaning bath with efficiency.

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.

Apparatuses and methods of optically analyzing fluid within a pipette are described herein. In an embodiment, an optical reader subassembly includes a pipette configured to aspirate and hold a fluid sample within its tip, a housing configured to receive at least the tip of the pipette through a reentrant seal so that the tip of the pipette is located in a light tight manner within an internal area, a light source positioned to be in proximity to the tip of the pipette when the tip of the pipette is received by the housing, the light source configured to project light through the tip of the pipette and onto the fluid sample held within the tip, and an optical sensor configured to take a reading of the fluid sample held within the tip of the pipette without any of the fluid sample being injected from the pipette.

An automatic analyzer includes a plurality of storage container holding units, a dispensing container holding unit, a plurality of dispensing devices, a dispensing abnormality detector, and a drive control unit. The plurality of dispensing devices each include a dispensing probe. The dispensing abnormality detector is provided in each dispensing device. The drive control unit is configured to control driving of each dispensing device based on a detection result of the dispensing abnormality detector. If a dispensing device in which an abnormality is detected is a first dispensing device, the drive control unit is configured to cause a dispensing process of a cycle in which the abnormality is detected to be performed again. If the dispensing device in which the abnormality is detected is not the first dispensing device, the drive control unit is configured to end the dispensing process of the cycle and start the next cycle.

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.

Provided is an automatic analyzer that can perform a reagent preparation/disposal operation comfortably and smoothly as when printing a reagent list such as a reagent preparation/disposal list on paper even without printing the reagent list. The automatic analyzer that performs analysis using a sample and a reagent, the automatic analyzer including: a storage unit that stores reagent information related to a reagent remaining amount or a reagent expiration date of each of reagent containers; and a display unit that displays a reagent list in which reminder information that gives a reminder to an operator is assigned to each of setting positions of the reagent containers based on the reagent information stored in the storage unit. The reagent managing unit updates display of the reagent list such that a reagent container selected by the operator is visually identifiable while the reagent list is displayed.
