Myth 1: Clean workbenches instead of biological safety cabinets

At present, many hospitals are using a large number of medical clean workbenches. Many operators believe that the two types of equipment have the same shape and similar functions, and believe that the samples they operate are ordinary samples, which are not highly pathogenic. In fact, there are essential differences between the biological safety cabinet and the clean workbench. The clean workbench will blow the purified air through the high-efficiency filter down through the work area to protect the sample. Since the work area is a positive pressure area, the air overflows through the operation window. , which only protects the sample, but does not provide protection for the operator and the environment. If the operation contains any known or potentially pathogenic aerosols, it will bring great hidden dangers to the operator.

The biological safety cabinet is a negative pressure purification workbench, which can prevent the operator and the environment from being exposed to harmful aerosols generated in the laboratory process, and is a cage of infectious microorganisms. Samples, working environment. Therefore, biosafety cabinets should be used in clinical inspection, diagnosis, pathological analysis, preparation of tumor drugs, and related biomedical research institutes and laboratories in hospitals.

At the same time, for the sake of safety, medical units and related laboratories should re-evaluate the microbial risk in the laboratory. If there is potential danger, the original clean workbench should be replaced in time, and biological safety cabinets should be selected as needed.
