Gene detection equipment

Abstract

The invention discloses gene detection equipment, and relates to the field of gene detection.The gene detection equipment comprises a safety cabinet, the safety cabinet comprises an upper-layer cabinet body and a lower-layer cabinet body, the upper-layer cabinet body is used for processing and detecting gene samples, and the lower-layer cabinet body is used for transporting PCR plates; three mutually independent mounting chambers are arranged in the upper-layer cabinet body, three mounting chambers are arranged in the lower-layer cabinet body, and door opening and closing assemblies are arranged between each mounting chamber of the upper-layer cabinet body and the corresponding mounting chamber of the lower-layer cabinet body and between the adjacent mounting chambers of the lower-layer cabinet body; an airflow control system is arranged in the upper-layer mounting chamber and is used for controlling the air pressure conditions of the three upper-layer mounting chambers, so that the air pressures of the three mounting chambers are sequentially reduced. By means of the gene detection equipment, automatic and efficient gene detection is achieved, pollution-free transfer of gene samples from sample adding and purification to amplification detection is guaranteed, and cross contamination is avoided.

Description

[0001] The parent filing date of this divisional application is October 19, 2020, the application number is 202011116049.5, and the invention name is "genetic testing equipment". technical field [0002] The invention relates to the field of gene detection, in particular to a gene detection device. Background technique [0003] Genetic testing refers to the analysis of the base sequence of a specific DNA fragment, that is, the arrangement of adenine, thymine, cytosine and guanine; a gene is the basic unit of inheritance, a DNA or RNA sequence carrying genetic information, through replication, the The genetic information is passed on to the next generation, directing the synthesis of proteins to express the genetic information it carries, thereby controlling the expression of the traits of individual organisms. Genetic testing is a technology for detecting DNA through blood, other body fluids, or cells. It is to take the peripheral venous blood or other tissue cells of the te...

In this way, it is necessary to arrange test personnel in the middle of each partition room, without realizing automation, the efficiency is not high, and the isolation of partition rooms occupies a large space and the cost is very high

[0006] When designing a large-scale PCR laboratory as an integrated nucleic acid extraction and detection device, in order to prevent cross-contamination, it is often chosen to set the gradient air pressure and buffer area of ​​each working area to avoid cross-contamination. However, if multiple In the buffer room, it is necessary to disperse the transfer devices for multiple PCR plates, which will inevitably increase the volume of the equipment, and it is difficult to arrange multiple transfer devices; if only one buffer room is installed, it exists as the intermediate value of the gradient pressure, although it can ensure high pressure work. The area can avoid external pollution, and the low-pressure work area can avoid polluting the outside world, but it cannot prevent air from flowing from the high-pressure work area to the low-pressure work area through the buffer room, and air cross-contamination still occurs
