Abstract
An automatic analyzer according to the present invention is compact, mounting great number of reagents, having high processing ability. Reagent disks are arranged at inside and outside of a reaction disk. A reagent probe can inject a reagent into the position which is common position of both reagent disks. One of plural reagent probes approaches to one of reagent disks at one cycle. Plural reagent probes alternatively approach to the reagent disk. Therefore, the first reagents and the second reagents can be placed on both reagent disks. The mounting number of reagents can be increased without enlarging an analyzer. The cycle time can be shortened to make an automatic analyzer to have high processing ability.
Claims5
An automatic analyzer, comprising:
- reagent disks including a first reagent disk and a second reagent disk, plural reagent containers being arranged on a circumference of each of said first reagent disk and second reagent disk, said plural reagent containers including a first reagent container and second reagent container, said first reagent container receiving a first reagent to be dispensed at a first timing, said second reagent container receiving a second reagent to be dispensed at a second timing or a third timing;
- a reaction disk arranging plural reaction cells on a circumference thereof;
- an analysis section for analyzing reactions of samples and reagents received in said reaction cells;
- a first reagent dispensing probe for said first reagent disk, said first reagent dispensing probe sucking said first reagent in said first reagent container on said first reagent disk, said first reagent dispensing probe injecting said first reagent into said reaction cell positioned on a first reagent injection position of said reaction disk in an even number cycle of rotation cycles of said reaction disk;
- a second reagent dispensing probe for said second reagent disk, said second reagent dispensing probe sucking said second reagent in said second reagent container on said second reagent disk, said second reagent dispensing probe injecting said second reagent into said reaction cell positioned on a second reagent injection position of said reaction disk in an even number cycle of rotation cycles of said reaction disk;
- a third reagent dispensing probe for said second reagent disk, said third reagent dispensing probe sucking said first reagent in said first reagent container on said second reagent disk, said third reagent dispensing probe injecting said first reagent into said reaction cell positioned on a first reagent injection position of said reaction disk in an odd number cycle of rotation cycles of said reaction disk;
- and
