Background
In the process of diagnosis and treatment and nursing of medical care personnel, the transmission routes of infectious diseases mainly comprise contact transmission, air transmission and insect-mediated transmission:
1. contact propagation: the process that pathogen directly gets into the human body of susceptible from the infectious source, generally contact the transmission and take place in the treatment process, and the protection that current to medical personnel contact the transmission is more comprehensive.
2. Through the spread of insect media: infections caused by arthropods as transmission vectors, changes in the medical environment make the transmission via vectors uncommon in nosocomial infections.
3. Air propagation: many pathogens, after being excreted from infectious sources, are able to invade new susceptible hosts through the air by means of transmission including droplets, droplet nuclei and dust particles. The transmission mode of the droplets is mainly that the droplets containing a large amount of pathogens are discharged into the surrounding environment through the mouth and the nose when a patient exhales, sneezes and coughs, large droplets quickly fall to the ground, and small droplets temporarily stay in the air, so that the environment for droplet transmission is limited to the periphery of an infection source. The nuclei of proteins and pathogens left by the airborne suspension process by the loss of water are called droplet nuclei, which can drift to a remote location in the form of an aerosol, through which desiccation-resistant pathogens such as tubercle bacilli can spread. The droplets or secretions containing pathogens fall on the ground and form dust particles after drying, and the susceptible people can be infected after inhaling the dust particles, and all pathogens with strong resistance to the outside, such as tubercle bacillus and bacillus anthracis spores, can be transmitted through the dust particles.
The protection of medical personnel is extremely important for the airborne infectious diseases. However, in the protection measures for the medical care personnel in the existing medical care environment, the protection for air propagation is limited, including a mask, goggles and the like. This kind of protection mode is more limited, and is more effective to medical personnel to undertake treatment work, but in medical personnel's the in-process of carrying out diagnostic work, the shortcoming has: the medical personnel travelling comfort is very poor when long-term work, wears the gauze mask for a long time and causes certain influence to medical personnel's health, and medical personnel still have a large amount of health naked, and the protective effect is poor.
