Description
Technical field
The utility model relates to Biohazard Safety Equipment fields, and in particular to a kind of Biohazard Safety Equipment with finger.
Background technique
Biohazard Safety Equipment is that have infective experiment material for operation primary culture, bacterium strain and diagnostic sample etc.
It, can during so that it is avoided exposure to aforesaid operations for protecting operator, laboratory environment and experimental material when material
Can generate infectious aerosol and spatters and design.
The most important function of Biohazard Safety Equipment is protection staff, and protection product and protection environment, the realization of function is logical
Down current and front window inflow stream are completed jointly at the top of crossing, and down current and front window inflow stream are above front window operation port
It crosses, and flows into front window grid together and form protection air curtain, with isolating work area domain and external environment, and then realize protection staff
Purpose.In normal experimentation, the height of front screen distance from bottom workbench generally can be constant in 200mm, this height
Not only personnel's operation had been facilitated, but also harmful substance in the excessively high safety cabinet of open height is avoided to leak.However, during the experiment, such as
Fruit occurs accident (blower stop or filter damaged), and front screen needs to drop in time minimum point, working region and outer
Portion's isolation becomes physics (front screen) isolation from the isolation of protection air curtain, to effectively avoid outside the harmful substance in safety cabinet
Let out pollution environment, infection experiment personnel.
In order to convenient for the lifting of control front screen, generally be gone up and down during the experiment with two pedal floor push and front window
Operation button.Two pedal floor push is distinguished in different colors there are two pedal, controls the positive and negative rotation of motor respectively come before controlling
The rising and decline of glass pane.Front window descending operation button is generally located on display screen peripheral or display screen, passes through front window
Operation button controls the positive and negative rotation of motor to control the lifting of front screen.But using both the above control front screen lifting
Method has the following deficiencies: that front screen declines suddenly in 1. experimentations, air-flow flow into area reduce, front window inflow stream and
Vertical down current fluctuation is unstable, and the protection air curtain of down current and the formation of front window inflow stream will receive destruction, safety cabinet
In protection staff, protection product, protect the performance of environment can sharp fall.2. front screen declines suddenly in experimentation,
The hand that experimenter may be pushed down causes personal injury to experiment operator, influences the process of experiment.3. in experimentation
Front screen declines suddenly, and because manpower hinders the decline of front screen, the guide rail of front screen is possible to deform, guide rail sealing
Effect declines, and harmful substance, which may be revealed, in safety cabinet endangers experimenter and environment, and provides power source for front screen
Motor can shorten because of the service life that cannot run well.
