Description

A sterilization ventilation device for an infectious disease ward

technical field

The utility model relates to the technical field of ventilation devices, in particular to a sterilization ventilation device for an infectious disease ward.

Background technique

The infectious disease department treats patients with infectious diseases, and many infectious diseases are transmitted through aerosol transmission. Aerosol transmission refers to the mixing of droplets in the air to form aerosols, which can lead to infection after inhalation. Aerosol is a dispersion system in which solid or liquid particles are suspended in a gas medium, and the particle diameter is between 0.001 and 100 μm (mainly particles of 0.5-5 μm).

The air in the infectious disease ward contains infectious viruses. If it is directly ventilated and ventilated like a normal ward, the bacteria and viruses in the ward can easily spread to the outside world through the air, causing pollution to the air and infecting healthy people around. Therefore, it is necessary to design a ventilation device with sterilization function.
