A kind of Biohazard Safety Equipment easy to use
Technical field
The present invention relates to bio-safety field of purification, be specifically related to a kind of Biohazard Safety Equipment easy to use.
Background technology
Biohazard Safety Equipment is to have infective for operation primary culture, bacterium strain and diagnostic specimen etc.
During experiment material, it is used for protecting operator, laboratory environment and experiment material so that it is avoid exposing
Issuable infectious aerosol and spatters during aforesaid operations and design.
At laboratory operation liquid or semifluid, such as, shake, pour into, stir or liquid is added drop-wise to
Time on the surface of solids or in another kind of liquid, it is possible to create aerosol.And to agar plate streak inoculation,
With suction pipe inoculating cell culture bottle, to infect liquid be centrifuged and carry out animal operation time, these experiment
Room operation all may produce aerosol.The diameter cannot seen for these naked eyes aerosol less than 5 microns
And a diameter of 5~100 fine liquid of μm, laboratory worker is generally not capable of recognizing depositing of they
, and may suck or the other materials of cross-contamination work top.
After harmful substance is filtered by Biohazard Safety Equipment by gas operated device, and will filter after air be discharged to reality
Test outdoor, part returns to work box, reduces owing to aerosol exposes the laboratory infection and training caused
Support thing cross-contamination, and protect environment, prevent the pollution of the environment, but current Biohazard Safety Equipment work box
Inner space and observation window should not be cleared up, and observation window is fixed on casing not only to cause in operating process and operates not
The most also easily cause harmful substance to disseminate, and be discharged to that laboratory is outer and air capacity in work box can not regulate, make
Biohazard Safety Equipment uses restricted.
