Under, gaseous decontaminant 7 can persistently penetrate the high efficiency particle air filter 2 in biological pollution air filter.Therefore, this is practical
Novel that gas disinfection treatment in situ can be not only carried out to high efficiency particle air filter 2, also while realization carries out gas to laboratory 20
Body disinfection treatment achievees the purpose that the disinfection synchronous with laboratory 20 of high efficiency particle air filter 2.
For the utility model, referring to Fig. 1 to Fig. 3, in order to carry out the same of gas disinfection in situ to HEPA filter 2
When, the Disinfection Effect of HEPA filter 2 is reliably verified, the verification operation process of specific Disinfection Effect is as follows:
Firstly, the sealing cover 12 in Disinfection Effect authentication unit 100 in situ is removed (closed at this time before disinfection starts
Isolating valve 9 is in close state), net cup 11 is taken out out of the disinfection of Disinfection Effect authentication unit 100 in situ verifying chamber 10, and
Biological indicator 13 (such as bacillus subtilis piece) is placed in net cup 11；
Then, net cup 11 is put into disinfection verifying chamber 10, and sealing cover 12 is installed on disinfection verifying chamber 10；
Then, the closed isolating valve 9 for opening Disinfection Effect authentication unit 100 in situ, makes disinfection verifying chamber 10 and biology
It pollutes first chamber 21 in air filter to be connected to, opens gas circulating driving device 5 and carry out disinfection, so that in the same of disinfection
When, while being carried out disinfection compliance test result by Disinfection Effect authentication unit 100 in situ；
After disinfection process, it is single to close Disinfection Effect verifying in situ for discharge 20 indoor residual gas disinfectants 7 of experiment
The closed isolating valve 9 of member 100 opens sealing cover 12, takes out biological indicator 13, carries out subsequent culture, judge sterilization
Effect.By positive control, such as culture is feminine gender, then sterilizes qualification.
It should be noted that the regulation for " disinfection technology standard (2002 editions) " printed and distributed according to the Ministry of Public Health, in air sterillization
In common indicator bacteria include staphylococcus albus, bacillus subtilis black variety gemma etc..It, can be to filter in actually disinfection evaluation
The scraps of paper or stainless steel substrates etc. are prepared into biological indicator 13 as bacterium or the carrier of gemma, by bacterial suspension drop on carrier
(i.e. bacterium piece).Bacterium piece oneself can be prepared, and also can purchase finished product, have the bacterium piece of domestic and imported to sell on the market, as Fourth Ring is raw
Object etc..
After bacterium piece is ready to, before carrying out disinfection, needs to carry out experimental group, be divided into disinfection group, positive controls and yin
Property control group.Wherein, disinfection group is the evaluation that carries out disinfection in the equipment for need to be put into this patent, and for disinfection group, biology refers to
Show agent 13 (i.e. bacterium piece) by disinfection treatment；Positive controls, bacterium piece is without disinfection treatment.
After disinfection, the bacterium piece of disinfection group and positive controls need to be according to existing " medical institutions' disinfection technology standard
(2002 editions) " regulation carry out subsequent processing, subsequent processing steps generally comprise following steps:
It is eluted step 1: the bacterium piece of the bacterium piece after disinfection or blank group is respectively put into sterile eluent；
Step 2: 1mL eluent is taken to be put into sterilized petri dishes, pours into and be cooled to 55 degree of culture medium, it is to be solidified；
Step 3: the plate in second step to be put into 24~48h of culture in 37 degree of constant incubator, meter is then taken out
Number；
Step 4: negative control group, i.e., be added plate for blank eluent, be subsequently poured into culture medium, according to same step
Suddenly it is operated and is cultivated.The step is in order to which the operation for proving used reagent and being related to is sterile working.Negative control group
Plate without bacterial growth, it was demonstrated that experiment is effective.
Step 5: result calculates.Wherein the obtained result of positive controls is blank group clump count, and disinfection group obtains
It as a result is disinfection group clump count.
The calculation formula of disinfection efficiency is as follows:
It sterilizes logarithm=lg (blank group clump count)-lg (disinfection group clump count)
According to the regulation of " medical institutions' disinfection technology standard (2002 editions) ", it is greater than 4 when sterilizing logarithm, as efficiently disappears
Poison, disinfection are qualified.It sterilizes logarithm and is greater than 6, then reach sterilizing level.If sterilizing logarithm is less than or equal to 6, illustrate to sterilize
It is unqualified.
