3 Terms and definitions

The following terms and definitions apply to this document.

3.1

A mobile device used for the isolation and transportation of infectious disease patients, consisting of a cabin, a ventilation system, an air filter element and a pressure monitoring device

By adjusting the ventilation system, a negative pressure environment is formed in the cabin to ensure that the air in the cabin is only filtered by high-efficiency air filter elements before being discharged.

Go outside the cabin.

Note. Referred to as "negative pressure isolation cabin".

3.2

The air filter element used at the air inlet and exhaust port of the negative pressure isolation cabin generally consists of a filter element and a housing.

3.3 Air exchange

The ventilation value per unit time is calculated by dividing the volume of air entering per unit time by the volume of the space.
