Embodiment 1

[0030] see Figure 1 to Figure 5 , the figure shows a VHP disinfection and sterilization system for a biosafety IVC cage provided by Embodiment 1 of the present invention, including:

[0031] The IVC mainframe 1 is provided with an exhaust fan chassis 11 and a blower chassis 12 from top to bottom, the exhaust fan chassis 11 is provided with an exhaust fan, the top of the exhaust fan chassis 11 is provided with an exhaust pipeline 111, and the exhaust pipeline 111 There is a first valve body V1 on the top, and a first internal circulation pipeline 112 is also provided on the exhaust pipeline 111. The first internal circulation pipeline 112 is connected to the blower chassis 12. The valve body V2 is provided with a return air pipeline 113 on one side of the exhaust fan chassis 11, and a third valve body V3 is arranged on the return air pipeline 113, and a blower is arranged in the blower chassis 12, and an air inlet pipeline is arranged on the blower chassis 12 121, the air inl...

Embodiment 2

[0044] see Figure 1 to Figure 5 , the figure shows a VHP disinfection and sterilization system of a biosafety IVC cage provided by Embodiment 2 of the present invention. This embodiment further makes the following technical solutions as improvements on the basis of the above-mentioned embodiments: One end of the exhaust branch pipe 41 is connected to the exhaust main pipe 4, and the opposite end is fixedly installed on the air supply main pipe 5;

[0045] The exhaust main pipe and the air supply main pipe are fixedly installed on the frame body, the exhaust branch pipe is fixed by the air supply main pipe and the air supply branch pipe is fixed by the exhaust main pipe, so that the exhaust air branch pipe and the air supply branch pipe are not easy to be damaged, avoid leakage, and improve the exhaust air quality. The installation stability of the main pipe and the air supply main pipe.

Embodiment 3

[0047] see Figure 1 to Figure 5 , the figure shows a VHP disinfection and sterilization system of a biosafety IVC cage provided by Embodiment 3 of the present invention. This embodiment further makes the following technical solutions as improvements on the basis of the above embodiments: A second air supply filter box 15 is arranged on one side of the blower case 12 , and the air inlet pipeline 121 is connected to the second air supply filter box 15 .

[0048] The second air supply filter box performs coarse filtration on the gas entering the blower chassis, and the first air supply filter box performs high-efficiency filtration on the gas sent into the air supply pipeline to improve the filtering effect. During disinfection, the disinfection gas mixed with gaseous hydrogen peroxide in the first internal circulation pipe enters the air blower chassis through the second air supply filter box through the air inlet pipeline, and disinfects the second air supply filter box.

Abstract

The present invention provides a vaporized hydrogen peroxide (VHP) disinfection and sterilization system of a biosafety individual ventilated cage (IVC). The VHP disinfection and sterilization systemof the biosafety IVC comprises an IVC host, an exhaust fan case and an air feeder case are arranged in the IVC host from top to bottom, an exhaust pipeline is arranged at a top part of the exhaust fancase, a first internal circulation pipeline is also arranged on the exhaust pipeline, the first internal circulation pipeline communicates with the air feeder case, an air return pipeline is arrangedon one side of the exhaust fan case, an air inlet pipeline is arranged on the air feeder case, the air inlet pipeline communicates with the first internal circulation pipeline, an air feeding pipeline is arranged below the air feeder case, and a second internal circulation pipeline is arranged on one side of the air feeder case; an exhaust main pipe on a cage integrated frame communicates with the air return pipeline, and an air feeding main pipe on the cage integrated frame communicates with the air feeding pipeline; and a hydrogen peroxide sterilizer is connected with a second air outlet interface on the IVC host through an air inlet pipe and also connected with the exhaust fan case in the IVC host through an exhaust pipe. The provided VHP disinfection and sterilization system performshost or complete machine disinfection on the biosafety IVC and has high safety.

Description

technical field [0001] The invention relates to IVC equipment in the field of animal experiments, in particular to a VHP disinfection and sterilization system for a biosafety IVC cage. Background technique [0002] The biosafety IVC cage is a kind of IVC equipment used in the field of animal experiments. It sends clean air into the closed independent unit (cage or cage) where the experimental animals are kept, and discharges the exhaust gas of the closed independent unit. [0003] Existing biosafety IVC cages sterilize the filter components by injecting disinfectant gas to avoid leakage of toxic components on the filter components into the environment and cause secondary pollution. However, it is inconvenient to fill the IVC host with disinfectant gas, and it is easy to leak when the disinfectant gas is filled, which has potential safety hazards, and the complete biosafety IVC cage cannot be sterilized. Contents of the invention [0004] In view of this, the present inven...
