Description

Technical Field

[0001] The invention relates to the field of laboratory quality control product pretreatment equipment, and in particular to an incubation device for quality control products used in nucleic acid laboratories. Background Art

[0002] Nucleic acid detection technology can greatly improve the detection rate of viruses in routine blood screening for HBV, HCV and HIV. However, for such efficient and highly sensitive nucleic acid detection technology, there is no corresponding device to match it in the pretreatment of its essential products, quality control products, which will greatly reduce its detection performance and efficiency. This technology is mainly aimed at the pretreatment of quality control products before the experiment, in order to ensure that the subsequent test results of the experiment are timely, accurate and reliable, and greatly improve the detection performance and efficiency.

[0003] Quality control products used in nucleic acid laboratories are divided into negative quality control products and positive quality control products. Positive quality control products are mostly weak positive quality control products, in order to achieve the purpose of monitoring experimental performance. Normal quality control products need to be frozen to maintain their stability, and need to be thawed to room temperature when used in experiments. Quality control products need to be tested first during experimental testing, and subsequent experiments can be carried out normally.

[0004] At present, laboratory staff mostly do manual work to prepare quality control products before conducting experiments. First, they are directly placed from the freezer to room temperature for thawing, and then manually inverted to mix; second, they are manually rubbed to thaw and mix the quality control products; third, they are thawed at room temperature and then mixed with an oscillator. All three methods have disadvantages. First, manual operation is time-consuming and labor-intensive. The strength of manual inversion mixing or oscillator mixing is uneven. There may be differences in operation when handling different quality control products, resulting in invalid test results for some quality control products, and causing the judgment of all samples on the day to be invalid and need to be redone; second, after manual mixing or oscillator mixing, the positive substances in the quality control products will adhere to the inner cover or foam will be generated, and aerosol contamination is easy to occur when the cover is opened manually.

[0005] To this end, this application document provides an incubation device for quality control products used in nucleic acid laboratories. Summary of the invention
