Embodiment

[0043] figure 1 The basic structure of the automatic analyzer of this embodiment is shown. The device has: a sample container rack 2 that can accommodate a sample container 1 containing a test sample; a reagent rack 4 that contains a plurality of reagent containers 3 that contain reagents that react with various components of the sample; A reaction vessel rack 6 for a reaction vessel 5 that mixes a sample with a reagent; a dispensing tip rack 8 that accommodates a dispensing tip 7; a plurality of thermostats 9 that are set to more than two different temperatures; A disc 11 of a carrier 10 equipped with a plurality of reaction containers; and a detector 12 for detecting reactions.

[0044] In addition, the reaction container 5 of this example may be any container as long as it has little influence on the detection performance, and is preferably a 0.2 ml single tube (manufactured by Greiner, Germany).

Abstract

The present invention has an object to provide an automatic analyzer using a disc, which treats samples with different pretreatment times or samples with different measurement times requested at random with high throughput. The present invention relates to performing adjustment rotation, rotation returning to origin, and measurement rotation in specimen analysis using a disc having a plurality of sample positions on a circumference. The adjustment rotation is an operation for placing a desired sample position in a particular position for introducing a sample into the disc or discarding the sample. The rotation returning to origin is an operation for placing an origin of the disc in a particular position. The measurement rotation is an operation for rotating the disc at a predetermined speed for measuring a plurality of samples held by the disc.

Description

technical field [0001] The present invention relates to an analysis device having a disc capable of holding a plurality of samples. Background technique [0002] As an automatic analyzer for blood, urine, etc., an analyzer having a disc capable of holding a plurality of samples is known. In this analysis device, a detector, a sample introduction mechanism, a reagent addition mechanism, a cleaning mechanism, and the like are generally provided around the disk. Furthermore, by continuously introducing the sample from a specific position into the disc, and operating the detector while rotating the disc, the sample signal is detected in a timely manner. [0003] As a method of driving the disk, generally, the disk is rotated in one direction by one revolution or more within a predetermined time required for time-sensitive detection of the sample signal. Thereby, even if the sample introduction position is fixed at a specific position, it is possible to detect the sample signal...
