Abstract

The invention discloses a virus filtering system, a medical protective mask and a negative pressure isolation cabin, belonging to the technical field of virus filtering and protection. The virus filtration system of the present invention comprises a superhydrophilic filter membrane, a superhydrophobic airgel filter membrane and a heating and disinfection device, the aperture of the superhydrophilic filter membrane is 10-20 μm, and the pore size of the superhydrophobic airgel filter membrane is less than 100nm, the heating temperature of the heating disinfection device exceeds 56 degrees Celsius. The filtration system of the present invention performs filtration through a double-layer membrane, the super-hydrophilic filter membrane is used for preliminary filtration, and the super-hydrophobic airgel filter membrane is used for precise filtration. The air circulation system of the present invention realizes dynamic control of air volume and air direction, and strives for comfort for medical staff or patients while ensuring virus filtration efficiency.

Description

technical field [0001] The invention relates to a virus filtering protection device, which belongs to the technical field of virus filtering protection. Background technique [0002] At present, protective equipment and facilities play an important role in isolating the source of infection, blocking the transmission of microbial aerosols, and protecting susceptible populations. It is one of the fastest and most effective ways to prevent the spread of the disease. In recent years, some institutions in our country have accelerated the research on medical protective equipment, carried out the design of some protective equipment, and formulated relevant standards. However, judging from the current research and equipment status, these standards and methods are still in the stage of basic research and basic requirements, and cannot meet the complex actual situation of virus infection. After analysis, the following problems still exist: [0003] The filterability of the equipment...
