An automatic sampling system for high-throughput detection of sample tubes

Abstract

The invention discloses an automatic sample injection system for high-flux detection of sample tubes. The system comprises a sample plate used for containing the sample tubes, the sample plate is arranged on a sample injection plate through a rotating mechanism, and the sample injection plate is connected with a sample injection bottom box through a bin entering and getting-out driving mechanism; the sample plate enters or gets out of a bin relative to the sample injection bottom box under the action of the bin entering and getting-out driving mechanism; when the sample plate enters the bin, the sample tubes on the sample plate are matched with a sample tube lifting mechanism separately for lifting and sample suction; when the sample plate gets out of the bin, the sample tubes on the sample plate can be replaced. When entering the bin, the sample plate can be matched with the sample tube lifting mechanism to achieve sample injection of the sample tubes on the sample plate; when getting out of the bin, the sample plate can be taken out from the system to facilitate replacement of the sample tubes; the system has the functions of making the sample plate taken out, achieving automatic bin entering and getting-out, making the sample tubes rotate and positioned and achieving lifting and sample injection, and high-flux continuous detection of the sample tubes is effectively achieved.

Description

technical field [0001] The invention belongs to the technical field of blood cell analysis equipment, in particular to an automatic sampling system for high-throughput detection of sample tubes. Background technique [0002] Blood in vitro diagnostic analysis instruments, such as blood cell analyzers and flow cytometers, often encounter a large number of samples in the daily application of clinical users, such as blood routine testing, lymphocyte subset analysis, daily average The detection volume can reach hundreds of tubes of samples. For clinical users, it is an important core highlight of the instrument to improve the automation and intelligence of the instrument and reduce the time occupation of the operator. [0003] When the cell analyzer performs sample diagnosis, it is necessary to draw a certain amount of fluorescently labeled cells and other samples from the blood collection tube or test tube through the sample loading device, and pass the sample injection capill...

AI Technical Summary

Problems solved by technology

The structure of the scheme is relatively compact, but the scheme does not involve how to automatically rotate the rotating disk to select sample tubes, and the fixed rotating disk is not convenient for clinical users to place sample test tubes in batches, and there is still a lot of room for improvement
