Aerosol suspension device for evaluating stability of pathogenic microorganisms

The invention discloses an aerosol suspension device for evaluating the stability of pathogenic microorganisms. The aerosol suspension device comprises a rotating chamber, the gas inlet end of the rotating chamber is communicated with a dry gas supplementing unit, a saturated humidity gas supplementing unit, a biological aerosol leading-in unit and a compensation gas leading-in unit; the air outlet end of the rotating chamber is communicated with a temperature and relative humidity detector and a gelatin filter membrane sampler. The stability of different pathogenic microorganisms in the air under the conditions of different relative humidity, different temperature (controlling indoor temperature) and different death time is evaluated by measuring various indexes of the collected gas sample, such as nucleic acid copy or virus load and the like; and the influence of external environment conditions on infection pathopoiesis and transmission capability of the microbial aerosol can be deeply and systematically st
