Description

Technical Field

[0001] The utility model relates to the technical field of PCR laboratories, in particular to a purification and ventilation device for PCR laboratories. Background Art

[0002] The PCR laboratory is also known as the gene amplification laboratory. PCR is the abbreviation for Polymerase Chain Reaction. It is a molecular biology technique used to amplify specific DNA fragments and can be considered a special DNA replication outside of an organism. Through the DNA gene tracking system, the viral content in the patient's body can be quickly determined with an accuracy of up to the nanometer level. It can accurately detect the amount of hepatitis B virus present in the patient's body, whether it is replicating, whether it is contagious, how contagious it is, whether medication is necessary, and whether there are any abnormal changes in liver function. It can promptly determine which type of antiviral drug is most suitable for the patient, determine the efficacy of the drug, and provide a reliable test basis for clinical treatment. Because the laboratory produces pungent gases, the gas needs to be ventilated and purified.

[0003] Traditional ventilation and purification devices still have certain shortcomings when in use. Traditional ventilation devices cannot filter impurities in the gas when in use, which will cause impurities to enter the air duct, causing blockage inside the air duct, thereby reducing the ventilation rate inside the laboratory. In addition, the hood of the air duct is indeed a protective mechanism. When the hood is in the external environment for a long time, it is easy to cause the hood to be damaged, reducing the protectiveness of the ventilation device when in use. Utility Model Content

[0025] In this embodiment, Figure 1 and Figure 2As shown, the shape of the medium-efficiency filter section 2 is W-shaped, the material of the medium-efficiency filter section 2 is stainless steel, the medium-efficiency filter section 2 is connected to the electric closed valve 1, the conical wind hood with a protective net 3 is arranged on the top of the protective pipe 8, the conical wind hood with a protective net 3 is connected to the air duct 4, the shape of the protective pipe 8 is cylindrical, the material of the protective pipe 8 is stainless steel, and the protective pipe 8 is arranged on the top of the fan 7.

[0026] Among them, impurities in the gas can be filtered through the medium-efficiency filter section 2 to prevent impurities from entering the air duct 4 and causing blockage inside the air duct 4, thereby improving the purification ventilation rate inside the PCR laboratory. At the same time, since the electric sealing valve 1 and the fan 7 are used in conjunction, it is more convenient and efficient to purify the interior of the PCR laboratory.

[0027] In this embodiment, Figure 3 and Figure 4 As shown, the fixing rod 9 is L-shaped and is fixedly connected to the center of the side of the protective tube 8. The electric sealing valve 1 is rectangular in shape and is linked to the fan 7. The distance between the bottom mark of the conical wind hood with the protective net 3 and the fresh air outlet is 6m. The air duct 4 is made of plastic and extends to the outside of the protective tube 8.

[0028] Among them, the hood can be protected by setting a conical hood with a protective net 3 to prevent the hood from being damaged due to being in the external environment for a long time, thereby improving the protection effect of the conical hood.

[0029] Working process of the present utility model: When the PCR laboratory purification ventilation device designed by the present scheme is in operation, the linkage between the electric sealing valve 1 and the fan 7 can be used to control the purification ventilation of the PCR laboratory, so that the gas inside the laboratory passes through the medium-efficiency filter section 2 to filter the impurities in the gas, and then the gas enters the air duct 4 and is ejected through the air duct 4. At the same time, the air duct 4 can be protected by the conical wind cap with a protective net 3 to avoid damage to the air duct 4. At the same time, since the air duct 4 is inside the protective tube 8, the air duct 4 can be limited by the protective tube 8 to avoid the accidental dumping of the air duct 4, thereby improving the rate of purification of the gas inside the laboratory by the purification ventilation device.
