Design a pediatric isolation bed and characterization of its purification efficacy in ambient air

Abstract Patients with acute infectious respiratory illness may emit bio-aerosols containing pathogens to infecting susceptible hosts, including other patients and healthcare workers. This study aimed to design the pediatric isolation (PI) bed and evaluate its purification effect on aerosols and microorganisms in the air in experiment rooms and verify the general wards' purification efficiency. The PI bed is connected to a purification device that surrounds the child's head to prevent contaminants' spread into the room.We test the the purification effect of the PI bed in the experiment room and verified the purification effect of the PI bed in the hospital. The results showed that PI beds in the demonstration ward presented purifying effects on both smoke particulates and microorganisms like Staphylococcus albus (S. albus)and H1N1 virus. The Aerosol in the room in the hospital was then detected to validity the purification rate. Therefore, Isolation beds could be used in hospitals to reduce the risk of nosocomial infection to protect the health of doctors, patients, and visitors.
