Embodiment Construction

[0047] Fig. 1 is a diagram showing an example of a chemical analysis device of the present invention. The chemical analysis device 1 has a motor 11 , a holding plate 12 rotatable by the motor 11 , several test boxes 2 arranged on the holding plate 12 , a puncher 13 for punching the test boxes 2 , a heating device 14 and a detection device 15 . The operator prepares an inspection cassette 2 for each inspection item, mounts it on the holding plate 12, and starts the chemical analysis device 1 .

[0048] In the chemical analysis device of this example, the heating device 14 and the detection device 15 are respectively provided at different locations, but they can also be integrated to perform heating and detection at the same location. In addition, the heating device and the detection device are located on the upper surface of the holding plate 12 , but one or both of them may be arranged on the lower surface of the holding plate 12 .

Abstract

The present invention provides a chemical analyzing cartridge having a simple structure, and provide a chemical analyzer using it. The chemical analyzer has a motor, the holding disk which is rotated by the motor, a plurality of the inspection cartridges arranged on the holding disk, a drilling machine for drilling the inspection cartridges, a heater, and a detector. Each of the inspection cartridges includes a container formed by a recessed part and a substrate having a flow channel, and the cover which covers the container and the flow channel is mounted on the substrate. A solution is moved to the container on the outer peripheral side with respect to a rotary axial line from the container on the inner peripheral side with respect to the rotary axial line through the flow channel by utilizing centrifugal force formed by the rotation of the holding disk.

Description

technical field [0001] The present invention relates to a chemical analysis device that utilizes centrifugal force to move, mix, etc. a solution. In particular, it relates to chemical analysis devices using removable cartridges. Background technique [0002] JP 2003-502656 A describes a device for extracting DNA from a DNA-containing sample. In this device, a sample containing DNA is passed through a glass filter to capture DNA. Then, the washing liquid and the eluting liquid were passed through the glass filter that trapped the DNA, and only the DNA was recovered. The glass filter is provided on a rotatable structure, and reagents such as cleaning solution and eluent are held in each reagent container in the same structure. Each reagent flows by the centrifugal force generated by the rotation of the structure, and a valve is provided on the fine flow path connecting each reagent container and the glass filter, and when the valve is opened, the reagent passes through the ...
