Abstract Background: Airborne transmission is an important mechanism of spread for both viruses and bacteria in hospitals, with nosocomial infections putting a great burden on public health. Patients intensive care units are highly susceptible these by necessity already have incur high operating costs. Therefore, there urgent need economical medical device to prevent infections. In order achieve this goal, innovative pediatric isolation bed was developed. Methods: We investigated the position child air intake wind speed test local effect using computational fluid dynamics simulation technology. Following this, we conducted purification experiments cigarette smoke, sustained release Staphylococcus albus human adenovirus type 5 demonstrate efficacy.Results: The results showed that patient’s head should be placed as close inlet hood possible, value 0.86 m/s effective. efficacy demonstrated CFD technology smoke different kinds microorganisms.Conclusions: mobile economic, particularly useful where infectious wards unavailable, such primary clinical settings, control hospital acquired infection. This study provides new method prevention
