Embodiment Construction

[0021] The following is based on figure 1 , figure 2 Embodiments of the present invention will be described in detail.

[0022] (Example)

[0023] Examples of the present invention are shown below.

[0024] figure 1 It is a diagram showing the overall configuration of an automatic analyzer for biochemistry used in the present invention.

[0025] The automatic analysis device has: a sample tray 2 (sample arrangement storage unit) on which the mother sample 1 collected in a test tube or the like is installed; a dilution tray 3 for performing dilution processing of the mother sample 1; and a reagent bottle 4 for storing and storing 1. A reagent cold storage 5 for keeping cold; and a reaction disk 6 for rotating the reaction liquid at certain intervals and reacting at the same time.

[0026] The mother sample 1 is sucked by the mother sample sampling mechanism 7 and dispensed to the dilution elements 8 arranged on the dilution plate 3 . The diluent is discharged from the di...

Abstract

An automatic analyzer is free from limitations on layout of various mechanisms, and thus causing no bottlenecks, for example, in a space-saving design of the automatic analyzer. This invention includes a coaxial planar duplex arrangement of two dilution disks each with annularly disposed dilution cells, and the dilution disks A and B operate independently of each other. Various mechanisms (parent-sample sampling mechanism, diluent delivery mechanism, diluent / sample mixing mechanism, and diluted-sample sampling mechanism) used in a dilution process can each access the two dilution disks. The dilution process for a parent sample, executed on the dilution disks A and B, can be continuously conducted by providing a fixed delay in operational timing between the two dilution disks.

Description

technical field [0001] The present invention relates to an automatic analysis device for clinical use and an operation method of the automatic analysis device, and relates to a dilution treatment of a mother specimen. Background technique [0002] Conventionally, in clinical automatic analyzers, it has been required to reduce the amount of reaction liquid for the purpose of reducing the running cost required for inspection. The volume of the reaction solution is proportional to the volume of the sample used. To reduce the volume of the reaction solution, the sample must be made in a small amount. However, in the existing specimen sampling technology, there is a limit on the minimum sampling volume, so it is difficult to greatly reduce the volume of the reaction solution. [0003] Therefore, as a micro-sampling technique for samples, dilution processing of samples is generally performed. As a sample dilution treatment method, there is a method described in Patent Document 1...
