Description

Laboratory sterilization system and sterilization method thereof

Technical Field

The invention relates to the technical field of sterilization, in particular to a laboratory sterilization system and a sterilization method thereof.

Background

In the 40's of the 20 th century, the united states established a biological weapons research program and began to implement an "aerosol infection program" that utilized large numbers of pathogens as highly contagious diseases and continued to develop a series of microbiological, weaponry, and field tests. However, due to insufficient protection technology and consciousness of the microbiological experiment at that time, workers are not protected in place during the experiment, so that the infection accidents in the laboratory operation frequently occur. In 1979, anthrax bacillus leakage accidents occurred in anthrax drying plants in the weapon research base of the former Sovierweidela Loff region during production, which caused inhalation anthrax or skin anthrax to infect a large number of residents in the downwind direction of the base, and several dozens of people died. Along with the research of high-risk pathogens, laboratory biosafety accidents continue to continue in this period, developed countries such as English, American, ProSu Union, Canada, Japan and the like successively start the construction of biosafety laboratories to solve the safety problems, and the frequency of the laboratory biosafety accidents is reduced through the operation of different grades of biosafety laboratories and corresponding microorganism operation standard guidelines.

In 1979, the American Occupational Safety and Health Agency (OSHA) issued a pathogenic microorganism classification based on degree of harm, and first proposed the concept of four grades of pathogenic microorganisms and experimental activities thereof. In 1983, in order to reduce the occurrence of laboratory safety accidents, the WHO published the first version of the laboratory biological safety manual, and continuously revised the manual to guide various countries to carry out standardized management on the biological laboratories of the country, and made specific operating rules to guide the safe operation of pathogenic microorganisms. In 2004, after absorbing the laboratory management experience and the safety accident experience training of each country, the newly revised handbook (third edition) made clear requirements for hardware and software including facilities and equipment, personal protection and SOP in the laboratory. Meanwhile, in order to realize safer laboratory management and biosafety control, biological safety laws and regulations of the country are successively set up by each country, laboratory safety supervision and inspection are enhanced, and infection and leakage of pathogenic pathogens in the laboratory are controlled.

In the 80 s of the 20 th century, epidemic hemorrhagic fever laboratory infection accidents occur continuously in the world, and a three-level biosafety level (BSL-3) laboratory made in the first country of China is built by military medical academy of sciences for safely carrying out the experimental research, and relevant operation regulations are made. Subsequently, in order to develop AIDS research, a few BSL-3 laboratories were introduced by the original Chinese academy of preventive medicine, and the construction of the BSL-3 laboratories in China began. Meanwhile, the national biological safety standard is prepared from the end of the last 90 th century in China, and the national standard of biological safety of laboratories in China, namely the universal requirement of biological safety of laboratories (GB19489), is promulgated in 5 2004. On the basis, various departments issue respective laboratory biological safety regulations and rules successively to guide biological safety guarantee of microbial laboratories in various fields.

The application of the sterilization equipment is a powerful measure for protecting the physical health of the laboratory staff, the sterilization is closely related to the laboratory for many years, and the sterilization of the laboratory instruments is the fundamental guarantee for the laboratory staff to avoid infection.

The motor 75 of the filter unit cooperates with the reset device 76 to cause filtered dust and the like to fall into the ash collection device. The second suction pump 62 may also be connected by piping to the air outlet 61 of the first suction pump 48 or a plurality of air outlets 61 may be provided by piping in the vicinity of the second sterilization device 3 for sucking air when the second sterilization is started. In addition, the air purifier can be used for purifying the air in a laboratory at ordinary times, even if the air purifier is not used for sterilizing the laboratory. Wherein the preset angle is preferably any angle between 30 and 45 degrees.

In one embodiment, the laboratory sterilization method further comprises:

starting the determined second sterilization device;

wherein, mobile terminal includes:

the body is provided with a plurality of grooves,
