Background
The gene is a genetic basic unit, carries DNA or RNA sequence of genetic information, transmits the genetic information to the next generation through replication, and guides the synthesis of protein to express the genetic information carried by the gene, thereby controlling the character expression of organism individuals. The gene detection is a technique for detecting DNA by blood, other body fluids or cells, and is a method for taking peripheral venous blood or other tissue cells of a detected person, amplifying the gene information, detecting DNA molecular information in the cells of the detected person by a specific device, and analyzing whether the gene type, the gene defect and the expression function contained in the DNA molecular information are normal or not, so that people can know the gene information of themselves, and the etiology is determined or the risk of a certain disease of the body is predicted.
The most convenient sampling mode of gene detection is saliva, secondly is blood, and the current popular is generally through gathering the saliva sample and detecting, and the blood collection is compared saliva and is collected more conveniently and freely, and user's acceptance is also higher moreover. It is well known that the extraction of gene tests using saliva is by means of exfoliated cells contained within the saliva, rather than the saliva itself. Therefore, when a saliva sample is collected in the prior art, a person to be collected needs to scrape the upper and lower jaws as many times with the tongue as possible, and the number of the exfoliated cells can be ensured by slightly scraping the tongue with the teeth. The collected sample often fails to be detected due to insufficient number of the exfoliated cells, so that in order to ensure a certain number of the exfoliated cells, a sampler often scrapes the inner wall of the oral cavity of the sampled person by using a scraping blade, but the exfoliated oral cells of the scraping blade need to be placed in the saliva environment of the sampled person, saliva collection is performed after the scraping blade is needed, or the scraping blade is performed after the saliva collection, and sample pollution is easily caused when the two are combined, so that the accuracy of a detection result is influenced.
