Problems solved by technology

[0004] As an important equipment to protect experimental operators, the biological safety cabinet has an internal airflow alarm. The function of the airflow alarm is to prompt the technicians to stop the operation immediately and stay away from the safety cabinet. The personnel's safety awareness is weak and the response is not fast enough, which leads to the untimely evacuation and the inhalation of harmful gases. The existing safety cabinets have no corresponding safeguards

Embodiment

[0050] see Figure 1-11 , a high security biological safety cabinet, see figure 1 , 2 with Figure 4 , including a biological safety cabinet body 1, the biological safety cabinet body 1 includes a control panel 2 with a face recognition device and a screen door 3 with a servo motor (installing a face recognition device on the control panel is well known to those skilled in the art) technology), the shielding door 3 is connected to the output end of the servo motor through a transmission mechanism (the transmission mechanism is an existing technology), and the opening range of the shielding door 3 is 15-30cm, and the opening range of the shielding door 3 cannot be too large, otherwise it will The head of the person is placed at the air inlet, thereby increasing the risk of inhaling harmful gases. The opening range of the screen door 3 should not be too small, otherwise the hands will not be able to operate comfortably. The biological safety cabinet body 1 is close to the scre...

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...
