Biochemical reaction device and biochemical test system

Abstract

A biochemical reaction device and a biochemical testing system relate to the technical field of biochemical testing, the biochemical reaction device comprises a first shell, a second shell and a pressing assembly, the first shell is internally provided with an accommodating cavity, the accommodating cavity is internally provided with a partition assembly to divide the accommodating cavity into a first sub-cavity and a second sub-cavity, the first sub-cavity is used for storing a sample, the second shell is contained in the second sub-cavity, a containing cavity is formed in the second shell, the containing cavity is used for storing reagents, a transportation assembly is arranged on the second shell, one end of the transportation assembly extends into the second shell to be communicated with the containing cavity, and the other end of the transportation assembly extends in the direction close to the separation assembly; one end of the pressing assembly extends into the second sub-cavity to abut against the second shell, and the other end of the pressing assembly is pressed to push the second shell to move relative to the first shell so as to drive the other end of the conveying assembly to penetrate through the partition assembly to communicate with the first sub-cavity; and the sample in the first sub-chamber enters the accommodating cavity through the transportation assembly and reacts with the reagent in the accommodating cavity.

Description

technical field [0001] The invention relates to the technical field of biochemical testing, in particular to a biochemical reaction device and a biochemical testing system. Background technique [0002] The current biochemical test equipment, such as blood coagulation testing equipment and platelet function testing equipment, generally uses separate sample cups, reagent cups and reaction cups. Wherein, the sample and the reagent are stored in the sample cup and the reagent cup respectively. When carrying out the biochemical test, the sample and the reagent are sucked respectively by the sampling device, and they are moved into the reaction cup, reacted in the reaction cup, and the biochemical test is carried out. [0003] The above process requires complex sampling system, motion control and sampling precision control, and there are problems such as cumbersome operation, high equipment cost, and long test process time. In addition, for different samples sharing a sampling s...

[0003] The above process requires complex sampling system, motion control and sampling precision control, and there are problems such as cumbersome operation, high equipment cost and long test process time

In addition, for different samples sharing a sampling system, even if the sampling needle is cleaned through the flushing system, it may cause cross-contamination due to unclean flushing, affecting the accuracy, reliability and consistency of the test
