Virus filtering system, medical protective mask and negative pressure isolation cabin

Abstract

The invention discloses a virus filtering system, a medical protective mask and a negative pressure isolation cabin, and belongs to the technical field of virus filtering protection. The virus filtering system comprises a super-hydrophilic filtering membrane, a super-hydrophobic aerogel filtering membrane and a heating disinfection device, wherein the pore diameter of the super-hydrophilic filtering membrane is 10-20 microns, the pore size of the super-hydrophobic aerogel filtering membrane is smaller than 100 nm, and the heating temperature of the heating disinfection device exceeds 56 DEG C. According to the virus filtering system, filtering is carried out through the double-layer membrane, the super-hydrophilic filtering membrane is used for primary filtering, the super-hydrophobic aerogel filtering membrane is used for precise filtering, the heating disinfection device can achieve instant disinfection and virus killing, and the high virus filtering effect is achieved; according to an air circulation system, dynamic control over the air volume and the air direction is achieved, and the use comfort of medical workers or patients is achieved under the condition that the virus filtering efficiency is guaranteed.

Description

technical field [0001] The invention relates to a virus filtering protection device, belonging 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 route of microbial aerosols, and protecting susceptible populations. They are one of the fastest and most effective ways to prevent the spread of the disease. In recent years, some institutions in my 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, there are still the following problems: [0003] The filterability of the e...
