Abstract

The invention discloses a high-safety biological safety cabinet and a using method thereof, which belong to the field of biological safety cabinets. On the basis of the prior art, power-assisted leg guards are added to assist technicians to quickly move away from the safety cabinet, effectively improving the safety factor , the power-assisted leg guard has a double guarantee function. On the one hand: during normal experimental operations, the opening and closing of the screen door is controlled by the counteracting effect of the technician's leg and the power-assisted leg guard, so that the biological safety cabinet The main body is in a closed state, which will not cause the leakage of harmful gases; on the other hand: after the airflow alarm is triggered, the technicians will be evacuated actively by pushing out the power-assisted leg guards, reducing the stay time and effectively avoiding the inhalation of harmful gases. The power-assisted leg guard extends outward for a certain length, which can force the walking personnel to stay away from the biological safety cabinet body, thereby effectively reducing the interference to the air flow inside the biological safety cabinet body.

Description

technical field

[0001] The invention relates to the field of biological safety cabinets, in particular to a high-safety biological safety cabinet and a method for using the same. Background technique

[0002] The biological safety cabinet is a box-type air purification negative pressure safety device that can prevent the aerosol dissipation of certain dangerous or unknown biological particles during the experimental operation process. It is widely used in scientific research, teaching, clinical testing and production in the fields of microbiology, biomedicine, genetic engineering, and biological products. It is the most basic safety protection equipment in the first-level protective barrier of laboratory biosafety.

[0003] The working principle of the biological safety cabinet is mainly to suck the air in the cabinet outward to keep the cabinet in a negative pressure state, and to protect the staff through vertical airflow; the outside air enters the safety cabinet after be...
