Safety experiment table for research and development of tetravalent influenza virus subunit vaccine

Abstract

The invention relates to the technical field of experimental equipment, in particular to a safety experiment table for research and development of a tetravalent influenza virus subunit vaccine, which comprises a support table box, a partition internal plate, a liquid storage bin, an experiment table panel, a negative pressure extraction hole and an air exhaust fan, the space, located below the inner partition plate, in the supporting table box is a liquid storage bin, the experiment table panel is fixedly installed at the upper position of the supporting table box, and a plurality of sets of negative pressure extraction holes are formed in the surface of the experiment table panel in a penetrating mode; the negative pressure extraction hole is formed in the experiment table panel, so that the experiment table panel has an extraction function, scattered experiment liquid, formaldehyde and other harmful gases can be extracted and removed, near-distance harmful gas removal is achieved, meanwhile, the space above the experiment table panel is not occupied, and the experiment table panel is convenient to use. And external environment pollution caused by outward dissipation of harmful gas can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of experimental equipment, in particular to a safety experimental bench for research and development of a quadrivalent influenza virus subunit vaccine. Background technique [0002] During the research and development of the quadrivalent influenza virus subunit vaccine, it is necessary to add formaldehyde with a concentration not higher than a certain value to the virus harvest solution for inactivation. Into the air will cause harm to the experimenters. The traditional protection method often sets up negative pressure air extraction equipment in the laboratory to purify the air. However, due to the distance from the experimental table, the extraction effect is poor, and formaldehyde gas will still be inhaled by the experimenters. , If the air outlet is set directly near the top of the experimental table, it will occupy space and affect the experimental operation of the experimenter, and during the experimen...

Problems solved by technology

[0002] During the research and development of quadrivalent influenza virus subunit vaccines, it is necessary to inactivate the virus harvest liquid by adding formaldehyde with a concentration not higher than a certain value. Since formaldehyde gas is irritating and toxic, during the experiment, formaldehyde gas volatilizes Exposure to the air will cause harm to the experimenters. The traditional protection method often installs negative pressure exhaust equipment in the laboratory to purify the air. However, due to the distance from the experimental table, the extraction effect is poor, and formaldehyde gas will still be inhaled by the experimenters. , if the air inlet is directly set near the top of the test table, it will cause space occupation and affect the experimental operation of the experimenters, and during the experiment, there will be liquid spilled on the test table panel, which needs to be wiped manually, which is not only extremely inconvenient, but also has Dangerous, the traditional laboratory bench cannot realize the automatic removal of spilled liquid
