Description
Technical field
The present invention is more particularly directed to a kind of isolator attachment devices, belong to Bioexperiment device technical field.
Background technique
Experimental animal is important experimental material indispensable in life science, and experimental animal isolator is as one
Kind experimental animal special facilities can maintain isolator internal environments (locating for experimental animal by using a variety of methods that are effectively isolated
Environment) it is in external environment and is effectively isolated state (sterile or without extraneous contamination), if air is sent into after high efficiency particulate air filter,
And be discharged after high efficiency particulate air filter is handled, article can pass in and out cultured space after aseptic process.The equipment both can guarantee
Animal is isolated from the outside, and is able to satisfy specific environment required for animal；Meanwhile using isolator can be improved staff and
The safety of operation sequence avoids operator from wearing excessive protective garment, improves comfort level, the flexibility of operator's work,
Maloperation is reduced, level of security is improved；Infected material is entirely controlled, minimizes Polluted area.
Isolator is mainly that the internal environment that will be controlled by mutually is separated with external environment, make operation object and staff to
Separation avoids people from directly contacting with infected material, avoids infection substance escaping into environment, substance of avoiding infection loss.Thus
It needs to establish the intact isolator of airtight barrier, activity by force and the convenient and fast transfer chain of connection, sterilization fully and completely disappears
Malicious chain.Currently, animal isolator is widely used in animal productiong and experimental field.But due to experimental animal isolator
Quality is irregular in addition certain animal isolators there are mass defects, while carrying out scene in transportational process and in laboratory
Installation and debugging are likely to go wrong and influence the overall performance of equipment, or even cause infectious aerosol or venomous injurant
Matter leaks.
Isolator can be divided into positive pressure isolating unit and negative pressure isolator according to pressure.Positive pressure isolating unit refers to pressure in isolator
Higher than outside atmospheric pressure, it is chiefly used in clean animal raising (preventing external environment from infecting internal environment)；Negative pressure isolator then refers to
Pressure is lower than outside atmospheric pressure in isolator, and being chiefly used in Feed experiments (prevents the pollution of internal environment harmful substance external
Environment), biosecurity laboratory mainly uses negative pressure isolator, usual high-level biosafety laboratory installation negative pressure animal every
From the raising and experiment that device carries out infection animal.According to the biological safety protection performance of negative pressure isolator, and can be by isolator point
It misplaces after can not achieve origin reset, operation at non-closed isolator and closed isolation, generates surface leakage pollution, especially
It is that can produce the illegal opening of transfer gate in operation, transport, accident in the process, generates leakage.Existing transmitting staving with
Isolator is rotation connection, is pivotally connected between the transmitting bucket outer cover and isolator of isolator using multi link, causes to transmit bucket outer cover
Not tight with isolator seal when closing, transmitting bucket outer cover and bung cannot be normally to bit synchronous operation, i.e., closed animal isolation
Device is mainly used for being engaged in the isolator for the animal science research for carrying or having infected highly pathogenic pathogenic microorganism.Wherein, negative pressure
Since the conditions such as animal feeding, Baoding, pollutant process, sample transmitting require harshness, if condition does not reach requirement, generation is let out
The probability of leakage is very high, and the difficulty of experimental implementation is also very big.
