For this utility model, specifically install, by first draw-in groove 57 and the second draw-in groove 59, it is possible to achieve will pass The doorframe 61 for passing bucket is installed on the doorframe 54 of the first gas-tight door 7, is installed on the doorframe 54 so as to now pass bucket 8 in fact. At this time, by rotating the transmission bucket 62, the doorframe 54 of transmission bucket doorframe 61 and first gas-tight door 7 can be caused Sealing, and the second gas-tight door 63, the first gas-tight door 7 reach sealing state and formation one.

Additionally, the second gas-tight door 63 is unlocked with transmission bucket 8, by rotating the first gas-tight door 7 (i.e. the transfer gate) Switch handle 52, can open the first gas-tight door 7.Therefore, it is for this utility model, airtight by the second gas-tight door 63 and first Door 7, it is possible to achieve two-door airtight transmission, facilitates experimental work personnel to need to carry out the article of experimental implementation by transmitting bucket 8 The inside of the operation casing 1 is delivered to, effectively can be prevented in the operation casing 1 of the isolator in the transmittance process of article Contaminated air leaks to external environment.

For this utility model, implement, referring to Figure 12 and Figure 13, the detached type of the hollow, airproof Transmission bucket 8 could alternatively be pocket type detached type transfer device, can be used for transmit non-pointed article, in this utility model In, the pocket type detached type transfer device includes the transmission bag 66 for transmitting bag doorframe 660 and left end opening, the transmission bag door Second gas-tight door 63 is sealedly connected with frame 660；

First draw-in groove 57 and the 660 phase clamping of transmission bag doorframe, the second draw-in groove (59) and second gas The 63 phase clamping of close door；

The left end outer wall of the transmission bag doorframe 660 is provided with a transmission bag handle 661, facilitates experimental work personnel couple Transmission bag 66 carries out rotation process.

The right-hand member of the transmission bag doorframe 660 has at least two annular fixed grooves 64, and the fixed groove 64 leads to Cross the sealing fixation of the elastic rubber ring 65 transmission bag 66.

It should be noted that for this utility model, when transmitting article into isolator, sealing should be placed an article within first The end of transmission bag, then with the thermofusion device heat-sealing transmission bag of the sealing equipped with article, by rotating transmission bag handle 661, can The first airtight 7 and second gas-tight door 63 is opened simultaneously, and the related article being passed of transmission bag 66 of sealing is drawn in into isolation then In device, then hermetic bag is cut off from the centre in heat-sealing region with shears, removing heat-sealing has the transmission bag 66 of sealing of article, beats Transmission bag 66 is opened, article is taken out, then complete article transmission.Therefore, the detached type of this utility model offer is two-door airtight Transfer device, effectively can prevent in article transmittance process, and the contaminated air in isolator leaks to external environment.

In order to be more clearly understood from the use principle of the biological safe type fowl negative pressure isolator of this utility model offer, under Illustrate in the face of the leak detection flow process in situ that carried out using this utility model and disinfection process.

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 34 needs to be detected, (such as at the air inlet 31 of powered air-purifying device 3) aerosol generator should be used at its upstream 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 34 21) 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, photometer or particle counter are connected to into then First downstream sampling of aerosol mouth 35 of one-level exhaust-air filter 34 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 34 is calculated Efficiency, the filtration rank (i.e. the levels of the standard of filter efficiency) nominal with first order exhaust-air filter 34 are 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 34 Not, then explanation have leaked, conversely, explanation is without leakage.

For this utility model, when second level exhaust-air filter 36 needs to be detected, aerosol generator is connected The first downstream sampling of aerosol mouth 35 to first order exhaust-air filter 34 is (as the aerosol note of second level exhaust-air filter 36 Entrance), aerosol is then sent, after aerosol is stable, particle counter the second upstream sampling of aerosol is connected to into then Mouth 37, so as to carry out upstream sampling of aerosol, after reaching the concentration that the relevant criterion for pre-setting is required, particle counter is connected The second downstream sampling of aerosol mouth 40 is connected to, the filters scan leak detection sampling probe 38 is sampled and moved, to second Level exhaust-air filter 36 and its frame installed are scanned leak detection, judge that second level exhaust-air filter 36 and its installation frame are It is no to there is leakage.If during scanning sample, detecting doubtful leak source, it is then attached to be fixed at doubtful leak source position and adopts Sample, if the population for collecting continues to increase, illustrates that filter has leak source.

2nd, the disinfection process of isolator：Before sterilization, biological airtight valve 13 is closed so that the second level air draft is filtered Device 36 and the blower fan 14 it is separated, when then circulating disinfection way using gas, will be the disinfectant of gas depoisoning machine 100 defeated Outlet 101 is connected to air inlet 31 (i.e. as disinfectant inlet) by pipeline, by the disinfectant of gas depoisoning machine 100 time Closing in 102 is connected to gaseous decontaminant outlet 15, so as to form the sterilization loop of closed loop.Meanwhile, will also be used for checking sterilization Biological indicator's (biological indicator can for example be bacillus subtilises bacterium piece) of effect is placed into sterilization checking mouth 41 In interior net cup 70, closure 43 is closed, open stop valve 42, be then turned on gas depoisoning machine 100, so as to send gas depoisoning Agent, to inside the operation casing 1 of isolator and powered air-purifying device 33, first order exhaust-air filter 34, second level air draft filter Device 36 carries out sterilization in situ.

When formula disinfection way is crossed using gas one, then need to be connected to gaseous decontaminant outlet 15 by decontamination duct network The exhaust system or external environment of place laboratory；The decontamination duct network of isolator after sterilization terminates, is removed, biological airtight valve is opened 13, open the isolator ventilating system pair being made up of first order exhaust-air filter 34, second level exhaust-air filter 36 and blower fan 14 Remaining disinfectant is purged, and after purging terminates, taking out biological indicator carries out culture checking Disinfection Effect, then whole to sterilize Flow process is completed.
