The dust particles carrying bacteria, viruses and the like can form aerosol in a small space with poor ventilation, so that the dust particles enter the space in a short time to infect organisms; particularly, the floating dust (the particle size is less than 10 microns, such as common bacteria and viruses) in the aerosol can float in the air for a long time, and is easy to enter respiratory tract through human breath, so that the bacteria or viruses are spread; therefore, attempts should be made to block aerosol and similar airborne particle transmission pathways.
Most spaces in hospital wards are relatively narrow and poor in ventilation, and a large amount of bacteria, viruses and the like are attached to the surfaces of used articles, particularly sickbeds and bedclothes, of some patients with infectious diseases; when medical care personnel put in order and take in the used bedclothes, a large amount of chemical fiber fabric particles carrying germs float in the surrounding space along with the medical care personnel, which is very easy to cause cross infection between patients and the medical care personnel; the cross infection in hospital (hospital infection for short) greatly increases the morbidity of patients and the fatality rate of diseases, aggravates the pain of patients and the workload of medical care personnel, reduces the turnover rate of sickbeds, and causes great economic loss to patients and society.
Statistical data show that the additional fatality rate caused by hospital infection is 4% -33%, and the additional medical cost is $ 1000-4500/case; therefore, it is necessary to design a storage cover for preventing nosocomial feelings, which reduces the probability of nosocomial feelings.
