In order to be more clearly understood from the use principle of the biological safe type glove box type isolator of this utility model offer, Below the leak detection flow process in situ and disinfection process to being carried out using this utility model is illustrated.

1st, original position (original state when as just installing) the leak detection flow process of exhaust-air filter：When first order air draft is filtered When device 27 needs to be detected, at its upstream aerosol generator should be used (such as at the air inlet 24 of powered air-purifying device 3) Aerosol (finely ground particles) is sent, after aerosol is stable, in air intake surface (the i.e. exhaust outlet of first order exhaust-air filter 27 17) using photometer or particle counter, (photometer and particle counter can be used for aerosol in gathered air at place Concentration is calculated), the aerosol concentration from upstream is sampled, then photometer or particle counter are connected to into First downstream sampling of aerosol mouth 29 of one-level exhaust-air filter 27 carries out downstream sampling of aerosol, and (upstream and downstream may also be employed one Particle counter)；

After sampling terminates, according to the aerosol concentration percentage ratio of upstream and downstream, the filtration of first order exhaust-air filter 27 is calculated Efficiency, the filtration rank (i.e. the levels of the standard of filter efficiency) nominal with first order exhaust-air filter 27 is contrasted, so as to sentence Disconnected filter and its installation frame whether there is leakage, if being not reaching to the nominal filtration grade of first order exhaust-air filter 27 Not, then illustrate that filter or installation frame have leakage, conversely, explanation is without leakage.

For this utility model, when second level exhaust-air filter 30 needs to be detected, aerosol generator is connected The first downstream sampling of aerosol mouth 29 to first order exhaust-air filter 27 is (as the aerosol injection of second level exhaust-air filter Mouthful), aerosol is then sent, after aerosol is stable, then particle counter is connected to into upstream aerosol thief hatch 31, from And upstream sampling of aerosol is carried out, after reaching the concentration that the relevant criterion for pre-setting is required, particle counter is connected to down Faint breath colloidal sol thief hatch 34, is sampled and is moved the filters scan leak detection sampling probe 38, and second level air draft is filtered Device 30 and its frame installed are scanned leak detection, judge that second level exhaust-air filter 30 and its installation frame whether there is and let out Leakage.If during scanning sample, detecting doubtful leak source, it is then attached to be fixed sampling at doubtful leak source position, if adopting The population for collecting continues to increase, then illustrate that filter has leak source.

2nd, the disinfection process of isolator：Before sterilization, biological airtight valve 12 is closed so that the second level air draft is filtered Device 30 and the blower fan 13 it is separated, when then circulating disinfection way using gas, by the disinfectant of gas depoisoning machine 100 Delivery outlet 101 is connected to air inlet 24 (i.e. as disinfectant inlet) by pipeline, by the disinfectant of gas depoisoning machine 100 Recovery port 102 is connected to gaseous decontaminant outlet 14, so as to form the sterilization loop of closed loop.Meanwhile, will also be used for checking and disappear Biological indicator's (biological indicator for example can be bacillus subtilises bacterium piece) of toxic effect fruit is placed into sterilization checking mouth In net cup 70 in 35, closure 37 is closed, open stop valve 36, be then turned on gas depoisoning machine 100, disappeared so as to send gas Toxic agent, the inside of operation casing 1 and powered air-purifying device 26, first order exhaust-air filter 27, second level air draft to isolator Filter 30 carries out sterilization in situ.

When formula disinfection way is crossed using gas one, then need to be connected to gaseous decontaminant outlet 14 by decontamination duct network The exhaust system or external environment of place laboratory；After sterilization terminates, the decontamination duct network of isolator is removed, open biological airtight valve 12, open the isolator ventilating system pair being made up of first order exhaust-air filter 27, second level exhaust-air filter 30 and blower fan 13 Remaining disinfectant is purged, and after purging terminates, taking out biological indicator carries out culture checking Disinfection Effect, then entirely sterilize Flow process is completed.

Understand that this utility model has the advantages that based on above technical scheme：

1st, the isolator that this utility model is provided possesses high biological safety protection performance.The structure of the isolator and accessory are filled It is standby to adopt gas-tight design, entirety that there is good mechanical isolation performance；It is negative pressure in normal operating condition, isolator, while The isolator ventilating system being made up of first order exhaust-air filter 27, second level exhaust-air filter 30 and blower fan 13 can be in isolator Glove occur improving exhaust air rate under damaged or dropping situations automatically, make breakage or glove port air keep being inwardly directed flowing, Effectively reduce risk of the leakage of aerosol to isolator external environment condition in isolator；Isolator supply air system installs efficient air-supply Filter, exhaust system installs altogether first order exhaust-air filter 27,30 two high efficiency particulate air filters of second level exhaust-air filter, has Standby leak detection in situ and the measure sterilized, can effectively improve its biological safety.
