Abstract
The invention discloses a reaction bin with a square opening for an in vitro diagnostic device. The reaction bin comprises a bin body; the bin body consists of a bin chamber and a bin bottom; an upper opening of the bin chamber has a square structure; the bin chamber comprises an upper bin chamber and a lower bin chamber, wherein the upper bin chamber has a quadrangular structure, and the lower bin chamber has a rectangular pyramid-shaped structure; a first right side wall of the upper bin chamber and a second right side wall of the lower bin chamber incline towards a central axis of the bin bottom; an included angle alpha between the first right side wall of the upper bin chamber and the central axis of the bin bottom is larger than an included angle beta between the second right side wall of the lower bin chamber and the central axis of the bin bottom, and the bin bottom is a circular arc-shaped bottom; enrichment device(s) is / are arranged on the second right side wall of the lower bin chamber and / or a second left side wall of the lower bin chamber. The reaction bin has the advantages of being simple in structure, easy to manufacture and convenient to use; the wall thickness of the bin chamber is consistent, thus being evenly heated; the bin bottom is convenient for vortex and liquid absorption; the first right side wall of the upper bin chamber and the second right side wall of the lower bin chamber are arranged in an inclined way, so that the enrichment distance is reduced, the enrichment time is shortened, and the reaction capacity of the bin chamber is guaranteed.
Description
technical field [0001] The invention relates to a reaction chamber for in vitro diagnostic equipment detection, in particular to a reaction chamber with a square opening for in vitro diagnostic equipment. Background technique [0002] Gene amplification technology, also known as cell-free analysis and cloning system, can amplify a very small amount of target DNA millions of times, thereby greatly improving the analysis and detection ability of target DNA molecules, and can detect single molecule DNA or every 90,000 DNA molecules. A sample containing only one target DNA molecule in a cell has been rapidly developed in the field of in vitro diagnostics for the detection of genetic diseases, infectious diseases and other diseases. In vitro diagnostic equipment such as automatic chemiluminescence immunoassay system, biochemical analyzer and other instruments are often combined with gene amplification technology to diagnose various diseases or viruses. According to statistics, t...
