[0002] A nucleic acid extractor is an instrument that uses matching nucleic acid extraction reagents to automatically complete the extraction of sample nucleic acid. The nucleic acid extractor usually places the extraction reagent kit inside it and uses the operation panel outside the nucleic acid extractor to start the magnetic rod and magnetic bead adsorption technology to adsorb and extract the test sample.
[0003] After searching, the publication number CN202021972178.X is a nucleic acid extraction instrument for laboratory testing with a protective effect, comprising a nucleic acid extraction chamber, a protective plate, a sliding rod and a movable lifting arm, one end of the interior of the nucleic acid extraction chamber is fixedly connected to the protective plate, the top of the interior of the nucleic acid extraction chamber is fixedly connected to a sterilization mechanism, the sterilization mechanism comprises a lampshade, an exhaust fan, a protective shell and an ultraviolet sterilization lamp, the top of the lampshade is fixedly connected to the top of the interior of the nucleic acid extraction chamber, the interior of the top of the nucleic acid extraction chamber is fixedly connected to the exhaust fan, the top of the lampshade is fixedly connected to the top of the interior of the nucleic acid extraction chamber, The end is fixedly connected to a protective shell, and the interior of the protective shell is fixedly connected to an ultraviolet sterilization lamp, one side of the interior of the nucleic acid extraction chamber is fixedly connected to a sliding rod, and the outer surface of the sliding rod is slidably connected to a mobile lifting arm, and the bottom end of the mobile lifting arm is provided with a test tube rack, one side of the bottom end of the interior of the nucleic acid extraction chamber is fixedly connected to an ultrasonic grinder, and one side of the ultrasonic grinder is provided with a heating structure, the other side of the bottom end of the interior of the nucleic acid extraction chamber is fixedly connected to a cooling mechanism, and one side of the nucleic acid extraction chamber is fixedly connected to a control room, and the nucleic acid extraction is achieved by providing a sterilization mechanism. The extraction device is anti-contamination. Contaminants are easily present in the nucleic acid extraction chamber when the test tube rack is placed in and taken out, which will have a certain impact on nucleic acid extraction. After the device is started, the ultraviolet sterilization lamp is also started. At this time, the ultraviolet sterilization lamp generates ultraviolet rays and the lampshade refracts the ultraviolet rays to the maximum extent, so that the nucleic acid extraction chamber is irradiated with ultraviolet rays for sterilization to the maximum extent. At the same time, the exhaust fan is started to discharge the contaminated microorganisms in the nucleic acid extraction chamber after ultraviolet treatment, thereby effectively preventing contamination in the nucleic acid extraction chamber. A heating structure is provided to achieve rapid heating during enzyme catalysis. When extracting nucleic acids, special enzymes need to be added to decompose various proteins in the cells to facilitate nucleic acid extraction. Therefore, a certain temperature needs to be reached during nucleic acid extraction to accelerate the enzyme decomposition rate. At this time, the electric heating wire is started to rapidly increase the temperature inside the first fixed frame. At the same time, the copper foil quickly absorbs heat and transfers it to the test tube rack, causing the temperature of the test tube rack to rise rapidly, thereby achieving rapid heating during enzyme catalysis. The existing nucleic acid extraction instrument lacks an internal protective structure, and the nucleic acid tubes are prone to shaking during transportation, resulting in leakage of liquid inside the nucleic acid tubes, leading to serious conditions such as infection of the staff.
