Embodiment

[0050] see Figure 1-11 , a high security biological safety cabinet, see figure 1 , 2 and 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 scree...

Abstract

The invention discloses a high-safety biosafety cabinet and a use method thereof, and belongs to the field of biosafety cabinets. A power-assisted leg guard is additionally arranged on the basis of the prior art to assist a technician in quickly getting away from the safety cabinet, the safety coefficient is effectively improved, and the power-assisted leg guard has a dual-guarantee effect. On one hand, when normal experiment operation is carried out, a shielding door is controlled to be opened and closed through the abutting effect of the legs of the technician and the power-assisted leg guards, so that when the technician leaves temporarily, a biological safety cabinet body is in a closed state, and leakage of harmful gas is avoided; on the other hand, after an airflow alarm is triggered, the technician is actively evacuated by pushing out the assisting leg guards, the staying time is shortened, harmful gas is effectively prevented from being inhaled, in addition, as the assisting leg guards extend outwards by a certain length, walking personnel can be forced to be away from the biosafety cabinet body, and thus the interference on airflow in the biosafety cabinet body is effectively reduced.

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...
