[0040] As Figures 1-3 Indicated, a biosafety corridor includes corridor enclosure, disinfection system and negative pressure control system.

[0041] Among them, as Figure 1 Indicated, the corridor enclosure includes ground layer 100, side wall 110 and top wall 120, side wall 110 is located on both sides of ground layer 100, top wall 120 is connected to both sides of side wall 110, side wall 110 and top wall 120 adopt inflatable structure, ensure that the corridor is completely sealed.The front end and the rear end of the corridor enclosure are respectively provided with an entrance and an exit, the entrance and the exit are both provided with inflatable door curtain 130, forming a closed space.Specifically, the corridor enclosure is rectangular, can also be arched or other shapes, the standard one section size is: height 1.5-2 meters, width 0.6-1.5 meters, length 20-30 meters. Figure 3As shown, the ground layer 100 includes a non-slip surface layer 180 and a leakage prevention layer 190, and is provided with inclined guide grooves 200 on both sides. The guide grooves 200 are V-shaped, and the lower end of the guide grooves 200 is connected to a detachable collection bag, which facilitates the collection and treatment of pollutants. The inflatable surface of the side wall 110 and the top wall 120 is made of three layers of composite TPU material. The inner layer is added with a phenol-based antibacterial agent, the middle layer is a tear-resistant fiber mesh, and the outer layer is coated with a silica hydrophobic coating, which enhances the anti-virus, tear-resistant and anti-virus adsorption capabilities. The side wall 110 is also provided with an operating glove socket 220 and a two-way transfer window 230. The operating glove socket 220 is embedded with a biological sealing ring (not shown in the figure), and the two-way transfer window 230 is provided with a switch door and an ultraviolet disinfection lamp (not shown in the figure). The switch door is set to ensure the airtightness of the corridor, preventing the spread of viruses through the transfer window. The ultraviolet disinfection lamp is automatically started after each transfer to ensure the cleanliness and safety of the two-way transfer window 230. The operator needs to wear protective gloves to prevent injury from the ultraviolet disinfection lamp.

[0042] As shown in Figure 2 The disinfection system includes an atomizing nozzle 140 and a UV lamp strip 150. The atomizing nozzle 140 is arranged inside the top wall 120 and covers the entire length of the corridor, with one nozzle per meter. The atomizing nozzle 140 is connected to an external disinfectant for atomizing disinfection, ensuring the cleanliness and safety of the interior of the corridor. The UV lamp strip 150 is arranged 30 cm above the inside of the side wall 110 to avoid contact with the pigs. The UV-C UV lamp strip 150 has a wavelength of 265 nm and an irradiation intensity of ≥100 μW / cm², ensuring efficient virus inactivation. The UV lamp strip 150 is equipped with an infrared sensor (not shown in the figure) to detect the absence of personnel or pig movement and automatically turn on, avoiding harm to humans and animals from ultraviolet light. The inside of the top wall 120 is also provided with a pheromone inducer box 240. The pheromone composition is specifically a compound of boar taint and estradiol, which is used to simulate pig pheromones and reduce pig collisions caused by stress. Combined with the use of the micro-current guide belt 210, the comfort and safety of pig transportation are further improved.

[0043] As shown in Figure 1 The negative pressure control system includes a filter exhaust port 160 and a negative pressure fan 170. The filter exhaust port 160 is arranged at one end of the corridor, and the negative pressure fan 170 is connected to the filter exhaust port 160 to extract air from the interior of the corridor, ensuring a negative pressure environment inside the corridor. The negative pressure control system is also equipped with a pressure sensor (not shown in the figure) to monitor the pressure changes inside the corridor in real time, ensuring the stability of the negative pressure control and preventing the leakage of viruses. Through negative pressure control, the air inside the corridor is always in a state of directional flow, further reducing the risk of virus spread.

[0044] When suspicious pigs need to be transported, first, the corridor is surrounded by an inflatable structure, ensuring that the side wall 110 and the top wall 120 are completely sealed, and then the corridor is connected to the transport vehicle at one end and the isolation house at the other end. When there is a height difference between the vehicle and the pig house, a support needs to be installed between the transport vehicle tail plate and the corridor floor to compensate for the height difference between the vehicle body and the ground. The pigs enter the corridor, and the micro-current guide belt 210 guides the pigs to move in one direction by stimulating them with weak current, reducing stress response. Start the negative pressure control system to ensure that a stable negative pressure environment is formed inside the corridor to prevent virus leakage. At the same time, the disinfection system starts to work, and the atomizing nozzle 140 automatically sprays disinfectant every 15 minutes to continuously disinfect the inside of the corridor, ensuring the biological safety during transportation. If a sick pig needs to be culled during transportation, the operator can inject a sedative through the operating glove port 220 of the side wall 110 to ensure safe operation. The contaminated instruments used during the operation are removed through the two-way transfer window 230, and the ultraviolet disinfection lamp provided with the transfer window is automatically started after each transfer to ensure the biological safety during instrument transfer. After the operation is completed, the dead pig body is transferred to a special harmless treatment bag, sealed and treated collectively to avoid virus spread. After transportation and operation are completed, terminal disinfection is performed. First, the remaining disinfectant is discharged into the detachable collection bag through the flow guide groove 200 for centralized treatment. Then turn on the UV-C ultraviolet lamp strip 150 and irradiate for 1 hour to ensure that all areas inside the corridor are thoroughly disinfected. After disinfection is completed, the negative pressure control system is turned off, the corridor is deflated and folded, and it is finally placed in a biological safety bag and incinerated to eliminate the risk of virus residue and secondary transmission.

[0045] The biological safety corridor of the embodiment of the utility model has high airtightness, high disinfection efficiency and stable negative pressure control function. Through the combination of the side wall 110 and the top wall 120 of the inflatable structure, the four-stage airtight barrier design (inflatable side wall 110 and top, ground layer 100, inflatable door curtain 130) and the disinfection system and the negative pressure control system, the virus blocking rate is significantly improved, and cross contamination is eliminated. The anti-skid and anti-leakage design of the ground layer 100 and the setting of the flow guide groove 200 and the detachable collection bag reduce the risk of spread of liquid and pollutants. The use of the micro-current guide belt 210 and the pheromone inducer box 240 reduces the stress response of pigs and improves transportation efficiency and safety. The infrared sensor of the ultraviolet lamp strip 150 and the ultraviolet disinfection lamp design of the two-way transfer window 230 further ensure the safety of humans and animals and the biological safety during operation. The utility model can be quickly deployed and is suitable for safe transportation and disposal of suspicious pigs, greatly reducing the risk of virus spread.
