Sample pretreatment module and sample pretreatment method using same

Abstract

Disclosed are a sample pretreatment module and a sample pretreatment method using same. The sample pretreatment module and the sample pretreatment method using same according to the present inventioncan minimize errors which can occur when a worker performs work manually, ensure accuracy and uniformity in sample pretreatment and test outcomes and, by enabling easy sample mixing and discharging, enhance working convenience and provide a user-friendly test environment. In addition, the module and the method can control and maintain a uniform pressure in the chamber so as to be able to prevent the outpouring of a sample even in the case of a drastic pressure change in the chamber, and can better transfer heat to the sample accommodated in the chamber, thereby heating the sample to a desiredtemperature within a short time and thus increasing the mixing and reaction efficiencies of the sample. Also, the module and the method use a magnetic force, resulting in more effective sample mixingand minimal mechanical operation, and enable an exact amount of the sample to be released after the pretreatment thereof.

Description

technical field [0001] The invention relates to a sample pretreatment module and a sample pretreatment method using it, and more specifically relates to a method for ensuring the reliability of test results by reducing operator errors in the sample pretreatment process, and can perform pretreatment simply and easily. Process, a sample pretreatment module that can quantitatively spit out pretreated samples and a sample pretreatment method using it. Background technique [0002] In general, fluid sample analysis is widely used in the field of diagnosis, such as analyzing blood and body fluid collected from patients for diagnosis, in addition to chemical and life engineering fields. [0003] Recently, in order to analyze these fluid samples more simply and efficiently, various analytical and diagnostic equipment and techniques that have been miniaturized have been continuously developed. [0004] In addition, one of the key points in the method of analyzing these fluid samples...

AI Technical Summary

Problems solved by technology

[0006] Typically, a pipette or pipette is used to prepare fluid samples for this purpose, but for samples from lab-on-a-chip or lab-on-a-tip units In terms of analysis, the amount of sample used for pretreatment is very small, and it needs to be processed very accurately. Therefore, it is not easy for the operator to directly use a pipette or a pipette to accurately pretreat the very small amount of sample required. thing

[0007] Moreover, the on-site inspection method requires the step of pre-processing the collected samples before putting them into the measurement equipment, and the problem of the amount of sample applied again occurs in the step of putting in.
