Methods Numerical simulation and finite element simulation analysis were used to design two-layer framework, with multi-cavity air column supporting closed structure. High-efficiency filtration under low air resistance was realized by optimizing the category, proportioning, folding structure and filtering grade of the filtration materials.Intelligent regulation, monitoring and displaying in the tent microenvironment were implemented with PLC. Results The tent system had the filtration efficiency more than 99.99% against bio-aerosol, air column endurance of 24 h and negative pressure between 15 and 30 Pa, which took 10 min for deployment, 10 min to form negative pressure and 3 min to reconstruct differential pressure in the buffer room. Conclusion The tent system is gifted with high-efficiency blowing filtration, stable negative pressure difference, rapid deployment and high environment adaptability for infectious disease prevention and control.
