Abstract
The utility model belongs to the equipment technical field of biology laboratory and relates to a biosecurity hood of aerosol equipment for medical and veterinary laboratory; the biosecurity hood comprises an operating chamber which is internally provided with the aerosol equipment, and an exhaust separation chamber adjacent to the operating chamber; the biosecurity hood is characterized in that: a pipeline is arranged at the top part of the exhaust separation chamber and is connected with an air exhaust unit, the inlet of the exhaust fan is communicated with the operating chamber, and an air filtering pore plate is internally arranged in the inlet of the exhaust fan. The biosecurity hood has the advantages that: the fan outside the safety hood is opened, the inside of the operating chamber of the safety hood is in a negative pressure state all the time, harmful aerosol exhausted from the aerosol equipment can be exhausted to outside by an exhaust system after being filtered by the air filtering pore plate; in addition, a glass movable door is arranged on the front surface, a pushing window which moves top and bottom is arranged on the side surface, the opening window is poured by biological test organism liquid, and the operation is convenient.
Description
Technical field
The utility model belongs to the biology laboratory equipment technical field, relates to a kind of medical science and veterinary laboratories usefulness, the bio-safety cover of aerosol apparatus.
Background technology
In medical science and veterinary laboratories, in some experimental implementation, comprise with aerosol challenge trial, the injection of animal nasal cavity of pathogen attack animal acquisition animal model and test, open the infectiousness experiment container and collect infectious material etc., because nuisance can be suspended in the gas medium, form the aerosol of particle diameter, very likely produce the aerosol that contains pathogen at 0.001-100 μ m.All there is the harm of infectivity or latent infection in these particulates to laboratory work person, and the bio-safety protection of therefore carrying out the laboratory operation personnel just becomes the problem that presses for solution.
The prior biological safety guard is used to improve the exhaust equipment and the blower fan of ventilation condition, all places in the cover body of bio-safety cover, has not only occupied operating space in the safety guard, and because exhaust system places top in the cover body, aerosol is upwards discharged.These safe quarantine measures often emptying are not thorough, and operating personnel are still probably by the aerosol infection in the bio-safety cover.
Summary of the invention
The purpose of this utility model is: provide a kind of simple in structure, isolation effect good, is applicable to the bio-safety cover that the aerosol challenge trial is used.
For achieving the above object, the technical scheme that adopts is: a kind of bio-safety cover, comprise the operating room of built-in aerosol apparatus and the air draft isolation ward adjacent with described operating room, it is characterized in that: described air draft isolation ward top is equipped with the exhaust blower group interface, be connected with the air draft unit by pipeline, air draft unit air inlet communicates with operating room, the built-in air filtration orifice plate of described air draft unit air inlet.
Described air filtration orifice plate and the mutual vertical disposed adjacent of described aerosol apparatus.
Described operating room moves door for making things convenient for personnel to pass in and out to be equipped with glass, and the side is equipped with to move up and down and pushes away window, as biologic test bacterium perfusion gathering hole.
Described operating room inner top and side are moved and are pushed away the window gathering hole and be equipped with ultraviolet germicidal.
Good effect of the present utility model is: the air draft unit is set at the outside of safety guard cover body, and high-efficiency air filtering orifice plate with the exhaust blower air inlet, arranged perpendicular is in a side adjacent with aerosol apparatus, so remains constant negative pressure state in the safety guard operating room.Harmful aerosol that aerosol apparatus is discharged after air filtration orifice plate filtration treatment, is entered in the outside air by exhaust system.Operating personnel are reduced greatly by the possibility of aerosol infection in the bio-safety cover.In addition, the utility model is equipped with the glass that makes things convenient for the staff to observe and pass in and out and moves door, and the side is equipped with as moving up and down of biologic test bacterium perfusion gathering hole and pushes away window, and is easy to operate.
Description of drawings
Below in conjunction with the drawings and specific embodiments utility model is described further.
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the B-B cutaway view of Fig. 1.
Among the figure, the 1-aerosol apparatus; 2-air draft isolation ward; 3-air filtration orifice plate; 4-exhaust blower group interface; 5,5 '-ultraviolet germicidal; The 6-operating room; 7-glass moves door; 8-moves up and down and pushes away window; 9-operating personnel's operative position.
The specific embodiment
Fig. 1～Fig. 3 is the utility model structural representation, by diagram as seen: a kind of bio-safety cover, comprise the operating room 6 of built-in aerosol apparatus 1 and the air draft isolation ward 2 adjacent with described operating room 6, it is characterized in that: described air draft isolation ward 2 tops are equipped with exhaust blower group interface 4, be connected with the air draft unit by pipeline, air draft unit air inlet communicates with operating room 6, the built-in air filtration orifice plate 3 of described air draft unit air inlet.
Described air filtration orifice plate 3 and described aerosol apparatus 1 mutual vertical disposed adjacent.
Described operating room 6 inner tops and side push away the window gathering hole and are equipped with ultraviolet germicidal 5(and 5 ').
Applicating example: described high efficiency filter orifice plate 3 is commercially available HEPA high-efficiency air filtering orifice plate, air draft unit exhausting makes in the safety guard with respect to the outer Negative Pressure Difference-17Pa of safety guard, air mean wind speed in the export-oriented safety guard of safety guard: the 0.678m/s(side pushes away the window place), 0.565 m/s(glass moves Men Chu), as seen shown in Figure 2, operating personnel's operative position 9 is in the upstream of air flow all the time, therefore operating personnel are reduced greatly by the possibility of aerosol infection in the bio-safety cover, and safe isolation effect is good.
Claims (4)
