Laboratory intelligent air-exhaust sterilization structure and use method

Abstract

The invention provides a laboratory intelligent air-exhaust sterilization structure and use method. The laboratory intelligent air-exhaust sterilization structure comprises an air inlet conveying tube, a sterilization filter tube and an air outlet conveying tube, wherein the air inlet conveying tube and the air outlet conveying tube are installed at the two ends of the sterilization filter tube and are provided with seal valves, the sterilization filter tube is internally provided with heaters and is internally and longitudinally provided with a high-efficiency filter, and the heaters and thehigh-efficiency filter are connected with a controller. The laboratory air-exhaust structure provided by the invention is easy to machine, reliable in sterilization and inactivation and easy to use and operate, live bacteria leakage will not appear, after the sterilization and inactivation, a filter element is convenient and safe to replace, filter bacteria filtration and mesh heater sterilizationare simultaneously performed while air supply is performed, and double-stage protection measures of the filter bacteria filtration and high-temperature sterilization are adopted.

Description

technical field [0001] The invention relates to the technical field of an airtight negative pressure laboratory air device. Background technique [0002] The biological safety protection laboratory is a biological laboratory and animal laboratory that uses a sealed and protected indoor negative pressure structure to prevent harmful biological factors from harming the human body and the environment, and meets the requirements of biological safety. According to the different risks, infectious pathogens are divided into four hazard levels. Microorganisms of the first-level hazard group: not related to human adult health and disease; microorganisms of the second-level hazard group: the diseases caused by humans are rarely serious, and there are usually methods of prevention and treatment; microorganisms of the third-level hazard group: Can cause serious or fatal diseases in humans, there may be methods of prevention and treatment; fourth-level hazard group microorganisms: can c...

Problems solved by technology

[0003] The final exhaust structure of the existing P3 and P4 laboratories has the following problems: the replacement of the high-efficiency filter adopts the bag-in-bag-out filter method of the 1950s and 1960s to replace the high-efficiency filter. This method replaces the high-efficiency filter and the high-efficiency filter is polluted Live bacteria, easy to leak and pollute the environment and human body

[0005] The following problems exist in the whole operation process: 1. Protective measures must be taken for the human body to prevent leakage; 2. The metal tools and accessories in operation are easy to damage the bag body; Body, micro openings, pleats on the bag mouth, poor sealing, resulting in leakage of germs and viruses. 5. The leaking of germs and viruses due to poor sealing during the cutting and separation process. 7 Tape-sealed bags, pleats at the mouth of the bag and the seal is not tight. The bag body is squeezed by external force during movement, and the airflow brings germs and viruses to overflow. 8 Bags are loaded and unloaded and sealed instantly without sterilization protection measures. Body seal without sterilization protection measures, germs and viruses overflow, 10 cut the bag body to leak, 11 tape protects the high-efficiency filter corner to prevent leakage, 12 tape protects the high-efficiency filter corner, prevents the bag body from being easily damaged during the bagging process, 13 corners Easy to damage the bag body, 14 hand force, the corner is easy to damage the bag body, 15 hand force, the corner is easy to damage the bag body, 16 bag support is easy to damage the bag body, 17 bag support corner plate is easy to damage the bag body

During the entire installation and replacement process, because the virus and bacteria on the high-efficiency filter are in a living state, in order to prevent the leakage of germs and viruses, the operator must wear protective clothing, the operation steps are complicated, and the operation must be very careful. Once leaked, it will be harmful to humans. serious harm to the environment
