Problems solved by technology

[0004] During the detection process, the head of the cotton swab needs to be cut off and placed in a centrifuge for centrifugation, but the existing cotton swab still contains a bamboo stick even if the head is cut off, and it is placed in a centrifuge, but the bamboo stick has buoyancy , easy to float on the supernatant, resulting in relevant DNA sticking to the bamboo sticks, thus affecting the detection results. The existing treatment method is to detect more than a dozen cotton swab heads for comprehensive judgment, which affects the detection efficiency

Description

technical field [0001] The invention relates to the field of DNA collection, in particular to a device for collecting and preserving DNA of contact biological specimens and a method for using the same. Background technique [0002] With the development of DNA gene sequencing technology, forensic science DNA technology has been widely used in crime scene investigation. In recent years, the pace of DNA database construction of public security organs across the country has been accelerating, and it is playing an increasingly important role in combating crime and protecting people's lives and property. Since the development of DNA analysis in our country, the application of this technology has successfully identified a large number of difficult cases, and played an important role in the detection of many criminal cases and the resolution of civil cases. [0003] At the crime scene, for most contact biological samples that cannot be directly extracted in kind, cotton swabs are u...
