[0002] The soft-pack isolator is a product used in sterile, SPF-grade group handling of mice and rats. It is applied in biomedical research, drug development, and animal experiments for the husbandry and preservation of laboratory animals, ensuring microbial control during experiments and guaranteeing the accuracy and reliability of experimental results. The soft-pack isolator is equipped with an extended glove. During the transition between feeding different batches of animals, researchers perform high-level sterilization of the soft-pack isolator to prevent cross-contamination of pathogens from different batches.

[0003] In existing technologies, hydrogen peroxide is commonly used to disinfect soft-pack isolators. However, the existing disinfection methods have the following problems: 1.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0023] like Figures 1 to 5As shown, a disinfection device for a flexible isolator includes a flexible isolator 1, a vaporizer 6, a fan 5, and a drying module 7. The vaporizer 6 is used to vaporize the disinfectant. Both the vaporizer 6 and the drying module 7 are connected to the air inlet of the fan 5. The air outlet of the fan 5 is connected to the flexible isolator 1 via a first pipe 2. The drying module 7 is connected to the flexible isolator 1 via a second pipe 3. A first valve 9 and a second valve 10 are respectively installed on the first pipe 2 and the second pipe 3. A branch pipe 4 is installed on the second pipe 3, located between the drying module 7 and the second valve 10. A third valve 11 is installed on the branch pipe 4, and a catalytic device 12 for decomposing the disinfectant is installed at the air inlet of the third valve 11. The drying module 7, the vaporizer 6, and the fan 5 together form a disinfection component.

[0024] In this application, hydrogen peroxide is selected as the disinfectant.

[0025] The first valve 9 is the air inlet valve, the second valve 10 is the air outlet valve, and the third valve 11 is the air replenishment valve.

[0026] When disinfecting the soft-pack isolator 1, air is introduced into the soft-pack isolator 1 by the fan 5 to make the gloves on the soft-pack isolator 1 fully inflated.

[0027] Furthermore, a humidity sensor 8 is installed between the drying module 7 and the fan 5. The humidity sensor 8 is used to detect the humidity of the gas flowing through the drying module 7.

[0028] In this embodiment, the fan 5 is a variable frequency fan. The variable frequency fan can flexibly adjust the wind speed.

[0029] In this embodiment, the catalytic device 12 is a platinum catalytic device 12. The platinum catalytic device 12 can catalytically decompose hydrogen peroxide gas into water and oxygen, thereby achieving the harmless treatment of the overflowing hydrogen peroxide gas and avoiding the health impact on the surrounding operators caused by the overflow of hydrogen peroxide gas.

[0030] In this embodiment, the air inlet valve, air outlet valve, and air supply valve are all ball valves.

[0031] The entire disinfection process of this utility model is divided into a pretreatment stage, a dehumidification stage, a disinfection stage, and a ventilation stage.

[0032] Before disinfection, the soft-pack isolator 1 will experience depressurization, with the internal air pressure equal to the external atmospheric pressure, resulting in a certain degree of contraction. Therefore, pretreatment of the soft-pack isolator 1 is necessary. During the pretreatment stage, the exhaust valve is closed, while the inlet valve and air supply valve are fully open, and the exhaust valve is not fully open. The fan 5 is running at full speed, and external air enters the soft-pack isolator 1 through the branch pipe 4, the fan 5, and the first pipe 2, maintaining a certain positive pressure value inside the soft-pack isolator 1 and causing the gloves to inflate. The frequency converter fan 5 of the disinfection machine is set to run at high speed, causing the soft-pack isolator 1 to inflate rapidly until the internal pressure reaches the target value.

[0033] Before formal disinfection, the interior of the flexible isolator 1 needs to be dried and dehumidified to prevent moisture in the air from condensing during the disinfection process. During the dehumidification stage, the opening angles of the inlet valve, exhaust valve, and air supply valve are adjusted, and the fan 5 is turned on to drive airflow inside the flexible isolator 1. When the air flows through the drying module 7, the drying module 7 can absorb moisture in the air, thereby achieving a drying and dehumidification effect inside the flexible isolator 1. During this stage, the valve opening angles can be adjusted according to the internal pressure of the flexible isolator 1: if the internal pressure is too high, the opening angle of the inlet valve can be reduced to reduce the ventilation volume, or the opening angle of the exhaust valve can be increased to increase the exhaust volume; if the internal pressure is too low, the opening angle of the exhaust valve can be reduced to reduce the exhaust volume, or the opening angle of the inlet valve can be increased to increase the intake volume. During the dehumidification stage, the humidity inside the flexible isolator 1 is monitored in real time by the humidity sensor 8. Once the humidity inside the flexible isolator 1 reaches the set value, the disinfection stage can begin.

[0034] During the disinfection phase, the air inlet valve, air outlet valve, and air supply valve are all in a semi-open state. The disinfection machine stores disinfectant (hydrogen peroxide), which is vaporized by the vaporizer 6 to produce hydrogen peroxide gas. The hydrogen peroxide gas is then introduced into the soft-pack isolator 1 by the fan 5, thereby disinfecting the soft-pack isolator 1. During this process, the drying module 7 continuously performs drying and dehumidification operations.

[0035] After the disinfection stage is completed, the injection of hydrogen peroxide gas into the flexible isolator 1 is stopped, and the ventilation stage begins. During the ventilation stage, the air inlet valve is fully open, the air outlet valve and the air supply valve are partially open, and the fan 5 runs continuously, causing the internal gas to circulate. In addition to its water absorption and dehumidification function, the drying module 7 is also equipped with an absorbent that can adsorb hydrogen peroxide gas. Activated carbon can be used as the absorbent. When the gas flows through the drying module 7, the absorbent in the drying module 7 absorbs the hydrogen peroxide gas inside the flexible isolator 1, thereby reducing the concentration of disinfectant gas (hydrogen peroxide) in the air until the concentration drops below a safe level.

[0036] In this invention, during the disinfection process, if the gas supply valve on pipeline branch 4 is fully or partially open, hydrogen peroxide gas may leak out from pipeline branch 4, potentially causing health hazards to surrounding personnel. In this embodiment, a catalytic device 12 is installed on pipeline branch 4 to catalytically decompose the leaked hydrogen peroxide gas, thus preventing health hazards to surrounding personnel.

[0037] During disinfection, this invention can inflate the gloves using a fan 5, thereby avoiding disinfection dead spots inside the gloves and improving the disinfection effect.

[0038] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
