Air microorganism experiment reaction equipment and application

Abstract

The invention discloses air microorganism experiment reaction equipment and application. The equipment is used for researching reaction changes of microorganisms in the air and comprises a reaction chamber, an air generator and an air sampling device; one side wall of the reaction chamber is provided with an air inlet and is connected with the air generator; an air outlet is formed in the other opposite side wall and is connected with the air sampling device; a fluorescent lamp and an ultraviolet lamp are mounted at the top of the chamber; the chamber is internally provided with a fan and a temperature and humidity sensor; the capacity of the reaction chamber is 150L to 500L; a hydrophobic coating is coated on an inner wall of the reaction chamber. The reaction chamber has a hydrophobic surface and the fan disturbs, so that microorganisms can stay in the air to the great extent; the capacity can meet different requirements on exposure time and subsequent collection and detection; various devices assembled on a chamber body can change different conditions of air reaction of the microorganisms, and real-time control and real-time detection can be realized; the propagation property of the microorganisms, in particular pathogenic bacteria, in the air is further known.

Description

technical field [0001] The invention belongs to the field of aerosols, and in particular relates to a method and equipment for studying the reaction changes of microorganisms in the air, a method and a device for studying the exposure reactions of the activity, infectivity and physical characteristics of microorganisms in the air. Background technique [0002] Air is an important medium for the transmission of microorganisms. Many human pathogenic bacteria are transmitted through the air and can cause outbreaks of infectious diseases. Microorganisms in the air include bacteria, fungi, viruses, rickettsia, mycoplasma and chlamydia, etc. Many of these microbial particles are pathogens that cause respiratory infections, such as Haemophilus influenzae, Legionella pneumophila, influenza virus, etc. In some special occupational environments and places where people gather, it is easy to cause outbreaks of infectious diseases, such as tuberculosis, measles, Q fever, swine flu, anth...

AI Technical Summary

Problems solved by technology

[0005] Most of the existing air microbial research devices cannot ensure that microorganisms stay in the air for a long time, and the controllability of environmental factors is poor, and the exposure time is short, so it is impossible to have a clear understanding of the changes of pathogenic bacteria in the air

What exactly happens to microorganisms in the air is still unclear, for example, the pathogenicity of microorganisms in the air changes and transmission is not well understood

In addition, the microbial exposure devices reported in the literature are generally large in size, high in cost, and difficult to completely sterilize, which may easily cause cross-contamination of multiple experimental reactions

There are also studies that transfer airborne microorganisms into the liquid phase for reaction, and design the liquid phase exposure reaction, which cannot reflect the real situation in the air
