Abstract

The invention relates to a biological safety protection cabin which is characterized by comprising an upper cabin body, a lower cabin body, a central control system and a negative pressure ventilation purification and disinfection system, wherein the upper cabin body comprises a closed negative pressure cabinet; the front and back sides of the negative pressure cabinet are respectively provided with at least one transparent window and an oversleeve operation port; the left and right sides of the negative pressure cabinet are respectively provided with a transfer window; the negative pressure ventilation purification and disinfection system comprises primary and secondary exhaust high-efficiency particle filters, an exhaust fan, a first tee joint, a pipeline electric closing valve, a second tee joint and a primary blowing high-efficiency particle filter which are sequentially connected through a ventilation pipeline; the third end of the first tee joint is connected with a laboratory exhaust system through an exhaust electric closing valve; the third end of the second tee joint is connected with a blowing fan through a blowing electric closing valve; the middle part of the ventilation pipeline is connected with a gas disinfection plant through a disinfection electric closing valve; an air inlet end of the primary exhaust high-efficiency particle filter is communicated with an air outlet of the upper cabin body; and an air outlet end of the primary blowing high-efficiency particle filter is communicated with an air inlet of the upper cabin body.

Description

Technical field [0001] The invention relates to a protective isolation device for harmful aerosols, in particular to a biological safety protection cabin used for the protection of biological aerosol animal infection experiments and the protection of pathogenic microorganisms infecting animals. Background technique [0002] In the prevention and control of infectious diseases, the pathogenic mechanism of pathogenic microorganisms, the evaluation of therapeutic drugs and the evaluation of vaccine experiments, etc., require experimental animal infection experiments. In these studies, whether it is the safe aerosol of pathogenic microorganisms in the experiment, or the aerosol of pathogenic microorganisms produced by the infected animals during the feeding process, it will cause laboratory environmental pollution or the infection of laboratory personnel. Therefore, it is necessary to treat these harmful biogas Sol for isolation protection. [0003] In the natural state, pathogenic mi...
