Background technology
At laboratory operation liquid or semifluid, for example shake, pour into, stir or be added to fluid drips on the surface of solids or in the another kind of liquid time, may produce aerosol.And to the agar plate streak inoculation, with suction pipe inoculating cell blake bottle, carry out centrifugal and when carrying out the animal operation, these laboratory operation all may produce aerosol to infecting liquid.The diameter that can't see for these naked eyes is the small liquid of 5～100 μ m less than 5 microns aerosol and diameter, and laboratory worker can not be recognized their existence usually, and may suck or the other materials of cross pollution work top.
Biohazard Safety Equipment is when having infective experiment material for operation primary culture, bacterium strain and diagnostic sample etc.; be used for protecting operator, laboratory environment and experiment material, make it avoid being exposed to issuable infectious aerosol and spatters in the aforesaid operations process and design.
Its principle be by filter with the harmful substance filtering after; air after will filtering by exhaust system is discharged to outside the laboratory, turn back to work top; reduce because aerosol exposes laboratory infection and the culture cross pollution that is caused, and the protection environment, prevent the pollution of the environment.
The structure of Biohazard Safety Equipment comprises support 20, cabinet 10 as shown in Figure 1, and cabinet 10 tops set out air port 11, and the bottom surface is provided with workbench 12, observation window 13 and air inlet 14, is provided with filter material and exhaust system in cabinet 10 inside.
Traditional Biohazard Safety Equipment top outlet inlet is received outside ventilating system, air inlet and lab space UNICOM, and therefore the gas that pollutes constantly enters the workbench operating space of Biohazard Safety Equipment, causes doublely doing super clean bench.
Summary of the invention
At above-mentioned defective, the purpose of this invention is to provide a kind of multiduty Biohazard Safety Equipment, with can only be in the Biohazard Safety Equipment that solves prior art as Biohazard Safety Equipment, function singleness, and the technical problem can not circulating filtration utilized of gas.
For achieving the above object, the present invention has adopted following technical scheme:
A kind of multiduty Biohazard Safety Equipment, comprise support and cabinet, be provided with workbench in the described cabinet, the top is provided with air outlet, operating space around workbench in the described cabinet is provided with blower fan, circulation air path, the operating space of described workbench, two sides and back all cut off with circulation air path; Described cabinet top is provided with a dismountable baffle plate, and described air outlet is blocked; All be provided with filter material between described air outlet and the baffle plate and between bench-top and the air channel;
When top flap seals air outlet, gas flows in described circulation air path when flowing to the air outlet place, is stopped that by described baffle plate the back flows to the workbench operating space of bottom, gets back to circulation air path by workbench again;
After top flap was opened, gas flowed in circulation air path, and part flows out through air outlet, and the part circular flow is to the workbench operating space of bottom.
According to the described Biohazard Safety Equipment of preferred embodiment of the present invention, described circulation air path comprises the main air duct between cabinet top and the bench-top, the back air channel at workbench back and the lower air duct of workbench bottom, described lower air duct, main air duct and back air channel UNICOM.
According to the described Biohazard Safety Equipment of preferred embodiment of the present invention, described workbench the place ahead is provided with observation window, and observation window comprises the glass door that can slide up and down the air inlet sealing of cabinet.
According to the described Biohazard Safety Equipment of preferred embodiment of the present invention, described deep bead can freely be dismantled.
According to the described Biohazard Safety Equipment of preferred embodiment of the present invention, described workbench is provided with mesh.
Owing to adopted above technical characterictic, make the present invention than prior art, have following advantage and good effect:
At first, the present invention adopts circulation air path, and top outlet inlet is blocked, and makes gas continue filtration cycle in cabinet, and the shoulder air inlet do not have the inflow air-flow substantially, reduces external contamination gas and enters, and can doublely do super clean bench;
Secondly, the present invention can reduce the pollution to filter, improves the service life of filter, and gas circulates in cabinet, and multiple times of filtration has improved the cleanliness factor of workbench operating space;
Once more, the present invention reduces the gas exchange of light slotting machine gathering hole than general clean bench, and better personal protection is provided.
Certainly, implement any one specific embodiment of content of the present invention, might not realize above whole technique effect simultaneously.
