Automatic reaction tube sample adding system

Abstract

The invention discloses an automatic sample adding system for a reaction tube. The automatic sample adding system comprises a mounting plate, a centrifugal disc rotationally arranged on the mounting plate and used for placing the reaction tube, a dilution disc used for placing a biochemical cup and a sample disc used for placing a sample container; the system also comprises a reagent sampling mechanism which is used for automatically sucking a reagent B in the reagent B box on the mounting plate and then adding the reagent B into the reaction tube; a diluting and sampling mechanism which is used for automatically sucking the reagent A in the reagent A box on the mounting plate, then adding the reagent A into the biochemical cup, and automatically sucking liquid in the biochemical cup and adding the liquid into the reaction tube; and a sample adding mechanism which is used for automatically sucking the sample in the sample container and adding the sample into the biochemical cup. According to the automatic sample adding system for the reaction tube, corresponding solutions can be sequentially added into the reaction tube, all actions are fully automatic, the reaction tube does not need to be manually transferred after sample adding is completed, and the sample adding efficiency is high.

Description

technical field [0001] The invention relates to the technical field of medical testing instruments, in particular to an automatic sample adding system for reaction tubes. Background technique [0002] In the medical testing instruments in the in vitro diagnostic industry, the automation of the solution sampling instrument in the reaction tube is not high. The traditional sample addition operation relies on complete manual sample addition, manual transfer of reaction tubes or the use of semi-automatic sampling equipment to complete the sample addition operation, but it is still necessary to manually place the sampled reaction tubes into the centrifuge plate in turn Carry out batch tumbling and mixing operations. This traditional method needs to be combined with manual operation every time the sample is added. Not only is the operation cumbersome, but also the manual transfer operation is likely to interfere with the sample. Contents of the invention [0003] The technical...

[0002] In the medical testing instruments in the in vitro diagnostic industry, the automation of the solution sampling instrument in the reaction tube is not high

The traditional sample addition operation relies on complete manual sample addition, manual transfer of reaction tubes or the use of semi-automatic sampling equipment to complete the sample addition operation, but it is still necessary to manually place the sampled reaction tubes into the centrifuge plate in turn Perform batch tumbling operation

This traditional method needs to be combined with manual operation every time the sample is added. Not only is the operation cumbersome, but also the manual transfer operation is easy to interfere with the sample.
