Problems solved by technology

When using a pump to transport multiple reagents through liquid, the reagents remain on the flow path wall, especially when the liquid is easy to remain on obstacles such as valves, once the remaining liquid does not flow, it may be in the confluent part with other reagents Pollution occurs on
In addition, when using valves to swit

Embodiment Construction

[0055] Refer below Figure 1-17 An example of the genetic testing device according to the present invention will be described.

[0056] figure 1 It is a diagram of the overall structure of the genetic testing device according to the present invention. The genetic analysis device 1 includes a holding disk 12 rotatably supported by a motor 11, a plurality of inspection components 2 arranged on the holding disk 12, a punch 13 for controlling the flow of liquid, a heating device 14 and a detecting device 15. The operator prepares the inspection modules 2 one by one for each inspection item, mounts the modules on the holding plate 12, and activates the genetic device 1.

[0057] figure 2 It is a block diagram of inspection unit 2. The inspection assembly 2 is configured in such a manner that the reagent cartridge 20 with the transparent reagent cartridge cover 22 joined to the reagent cartridge main body 21 is mounted on the inspection box 30 to which the transparent test cartridge...

Abstract

An analyzer and a structure for analysis with high performance are provided which can reduce contamination between the reagents when the valve components or a plurality of reagents are included. The present invention is a chemical analyzer to which a sample is introduced and into which a structure for holding a reagent reacting with the above described sample is housed, including a mechanism for detecting the above described sample after the above described reaction; in which the above described structure includes a reagent cartridge having reagent storing parts for storing a plurality of reagents, a connection part to which the above described reagent cartridge is connected, and a channel cartridge having reagent channels through which a plurality of the above described reagents flow, a sample channel through which the above described testing object flows, and a reaction region where the above described reagent is reacted with the above described testing object.

Description

Technical field [0001] The present invention relates to a chemical analysis device. Background technique [0002] Regarding the method of extracting DNA from a liquid sample containing DNA, WO 00 / 78455 discloses a microstructure and a method for inspection by amplification. In this device, the DNA mixture is passed through a glass filter as an inorganic matrix, and then washing and eluent are passed through to recover only the DNA. The glass filter is installed on a rotatable structure, and reagents such as washing liquid and eluent are kept in the reservoir of each reagent in the same structure. Each reagent flows under the action of centrifugal force generated by the rotation of the structure. The valve on the micro flow path connecting each reagent reservoir and the glass filter allows the reagent to pass through the glass filter. [0003] As a chemical analysis device that extracts and analyzes specific chemical substances such as nucleic acid from a sample containing multipl...
