Abstract
The utility model discloses a bio -safety laboratory pipeline is last degassing unit eventually. The device includes front end reducing fan housing, treat that disinfection tube says and terminal reducing fan housing, front end reducing fan housing, treats that disinfection tube says and terminal reducing fan housing is connected in order. The diameter ratio front end reducing fan housing of the preceding port of front end reducing fan housing is little with the diameter of treating the port that the disinfection tube way is connected. The terminal reducing fan housing of diameter ratio of the preceding port of terminal reducing fan housing is little with the diameter of treating the port that the disinfection tube way is connected. This end last degassing unit can carry out validity terminal disinfection to bio -safety laboratory exhaust pipe, reduces open pipeline when disinfection to the potential harm of human body, and low -risk, easy operation, practicality are strong.
Description
Technical field
This utility model relates to biocontainment laboratory equipment aspect, specifically a kind of biocontainment laboratory pipeline terminal disinfection device.
Background technology
At present, biocontainment laboratory exhaust duct is disinfected and does not put into effect relevant national standard specification, under most cases, only focus on the inner space sterilization of laboratory structure, and ignore the sterilization to ventilation shaft, there is certain potential safety hazard.Therefore, existing laboratory equlpment can not carry out safety and effectiveness sterilization for biocontainment laboratory exhaust duct.
Utility model content
In order to overcome above-mentioned technological deficiency, this utility model provides a kind of biocontainment laboratory pipeline terminal disinfection device.This terminal disinfection device can carry out effectiveness terminal disinfection to biocontainment laboratory exhaust duct, potential hazard to human body when reducing the sterilization of open pipeline, low-risk, easy to operate, practical.
Biocontainment laboratory pipeline terminal disinfection device of the present utility model is achieved through the following technical solutions:
A kind of biocontainment laboratory pipeline terminal disinfection device of the present utility model comprises front end reducing fan housing, pipeline to be sterilized and end reducing fan housing, and described front end reducing fan housing, described pipeline to be sterilized are connected in turn with described end reducing fan housing.
The diameter of the port that the diameter of the front port of described front end reducing fan housing is connected with described pipeline to be sterilized than described front end reducing fan housing is little.
The diameter of the port that the diameter of the front port of described end reducing fan housing is connected with described pipeline to be sterilized than described end reducing fan housing is little.
Undertaken by following operation when using device of the present utility model to sterilize: before pipeline, last two ends are tightly connected reducing fan housing, blower fan is used to send aerosol disinfection gas at front end reducing fan housing mouth, regulate end reducing fan housing aperture and blower fan air output to make pipeline form zone of positive pressure, aerosol disinfection gas is fully spread in pipeline.Meanwhile, bacillus subtilis sheet is placed at end reducing fan housing mouth.Setting sterilization required time, gather bacterium sheet after sterilization and cultivate, whether checking sterilization is effective.
This device, in conjunction with biocontainment laboratory building structure feature, during terminal disinfection, connects reducing fan housing at exhaust duct two ends, uses blower fan to send aerosol disinfection gas to, meanwhile, utilizes bacillus subtilis sheet to carry out disinfection compliance test result.Implement semi-enclosed sterilization for exhaust duct, ensure that disinfecting process is safe and effective.Effectiveness terminal disinfection can be carried out to biocontainment laboratory exhaust duct, reduce the potential hazard to human body when open pipeline is sterilized, there is low-risk, easy to operate, practical feature.

Fig. 1 is the structural representation of a preferred embodiment of a kind of biocontainment laboratory pipeline terminal disinfection device of the present utility model;
Fig. 2 is the front view of the biocontainment laboratory pipeline terminal disinfection device in Fig. 1.
Detailed description of the invention
Fig. 1 is the structural representation of a preferred embodiment of a kind of biocontainment laboratory pipeline terminal disinfection device of the present utility model, and Fig. 2 is the front view of the biocontainment laboratory pipeline terminal disinfection device in Fig. 1.From Fig. 1 and Fig. 2, the biocontainment laboratory pipeline terminal disinfection device of this preferred embodiment comprises front end reducing fan housing 1, pipeline to be sterilized 2 and end reducing fan housing 3, and front end reducing fan housing 1, pipeline to be sterilized 2 are connected in turn with end reducing fan housing 3.The diameter of the port that the diameter of the front port of front end reducing fan housing 1 is connected with pipeline 2 to be sterilized than front end reducing fan housing 1 is little.The diameter of the port that the diameter of the front port of end reducing fan housing 1 is connected with described pipeline 2 to be sterilized than end reducing fan housing 3 is little.
When using this terminal disinfection device, be first connected the two ends of pipeline 2 to be sterilized with end reducing fan housing 3 with front end reducing fan housing 1.Calculate conduit volume.Blower fan is used to send aerosol disinfection gas at pipeline 2 leading portion.Regulate the aperture of end reducing fan housing 3 and blower fan air output to make the inside of pipeline 2 form zone of positive pressure, make the fully diffusion in pipeline 2 of aerosol disinfection gas.Measure air quantity in the outlet of end reducing fan housing 3, make the ventilation rate of pipeline 2 be about 10%.Before sterilization starts, place bacillus subtilis sheet in the exit of end reducing fan housing 3, disinfecting time is 2 hours, under sterile working, bacillus subtilis sheet is gathered after sterilization, drop in aseptic meat soup pipe, put 37 DEG C of constant incubator continuous culture 7d, day by day observed results.After cultivating, meat soup liquid level has Mycoderma, has flocculent deposit, has and see muddiness, namely indicate bacteria growing during shake, be judged to be that sterilizing is defective in meat soup; Meat soup still clear and namely represent asepsis growth without precipitation after cultivating, simultaneously positive control bacillus subtilis sheet growth is normal, is judged to be that sterilizing is qualified.
