Sample dilution method and apparatus, sample analysis apparatus and storage medium

Abstract

The invention discloses a sample dilution method and an apparatus, a sample analysis apparatus and a storage medium. The sample dilution method comprises at least a dilution step, each dilution step comprises a primary sample absorption process and at least a weak solution absorption process in order until all the dilution processes are completed, and a diluted sample is obtained from a reaction cup corresponding to the final dilution process. wherein, the sample absorption process is characterized in that a to-be-diluted sample of a first predetermined amount is absorbed, the absorbed to-be-diluted sample is added in the reaction cup corresponding the dilution process, the weak solution absorption process is characterized in that a weak solution of a second predetermined amount is absorbed, and the absorbed weak solution is added in the reaction cup corresponding the dilution process, wherein the weak solution comprises a rinse-solution or a reagent. By employing the technical scheme,under prerequisite that a configuration process of a specific weak solution and a storage apparatus are not added, and an automatic dilution function of a high concentration sample is realized.

Description

Technical field [0001] The present invention relates to the technical field of medical devices, in particular to a sample dilution method and device, a sample analysis instrument and a storage medium. Background technique [0002] The sample analysis instrument is used to analyze and test the sample. Different test items have different requirements for the samples to be tested. For example, some test items require that high-concentration samples be diluted first, and the diluted low-concentration samples are used to complete the test. Currently, some analytical instruments are equipped with a dilution device that can automatically perform the dilution function. [0003] The automatic dilution device in the prior art includes: a diluent storage device, a reagent needle, and a cleaning device. Among them, the diluent storage device stores a specific diluent; the reagent needle will suck a predetermined amount of the specific diluent from the diluent storage device, and squeeze the ...

Problems solved by technology

[0004] However, the inventors of the present application have found that since the automatic dilution device in the prior art needs to use a specific diluent to dilute high-concentration samples, it is not only necessary to increase the configuration of the specific diluent, but also to add a separate diluent to the analytical instrument. The diluent storage device makes the automatic diluting device in the prior art have the disadvantages of making the structural adjustment of the analytical instrument larger and the development cost higher
