Abstract:
In order to meet the needs of patients with infectious disease patients for on-site isolation treatment,living and excrement treatment,a negative pressure isolation treatment chamber for prevention and control of infectious diseases was developed.Based on the principle of negative pressure isolation,a closed cabin body that can be quickly installed was designed,with a treatment area,a buffer room for patients entering and exiting,a buffer room for medical staff enter and exit,a temporary waste placement area,a comprehensive integrated pressure monitoring system,intelligent air intake system,intelligent and efficient exhaust air filtration system,intelligent sterilization system,lighting system,air microorganism collector etc.The negative pressure isolation treatment chamber for the prevention and control of infectious diseases can establish a negative pressure of≥15 Pa within 3 minutes,the protection efficiency of 0.3 μm particulate aerosol was≥99.999%,and the maximum disinfection space was 150 m3,which can effectively control the diffusion of pathogenic microorganisms and pollution to the environment,cut off the transmission route with healthy people.The negative pressure isolation treatment compartment for the prevention and control of infectious diseases can meet the isolation requirements of respiratory isolation,contact isolation,digestive tract isolation,insect isolation,etc.,meet the needs of the admission and treatment of infectious disease patients,improve the emergency response and rapid response capabilities of the epidemics The treatment cabin can be disassembled and placed in the storage box when not in use,which occupies a small area,is light and easy to carry,and has good social and economic benefits.
