Development of positive/negative pressure booth generating airflow for protection of medical staff from contagious respiratory pathogens.

ABSTRACT:

Background

The pandemic of COVID-19 caused confusion in medical settings because of increased patient load, and caused many infections among medical staff which occurred through exposure to bio-particles discharged from patients. The risk of exposure became maximum at the examination of patients, particularly in the collection of respiratory specimens. Effective interventions to reduce the risk are needed.

Methods

A one-person booth consisting of curtain walls, frames, and fan-HEPA filter-unit (FFU) was designed. Using the airstream from/to FFU, it has dual functions as a positive/negative pressure machine to prevent pathogens in patient's cough to reach the medical staff inside/outside the booth, respectively. The curtain walls and positioning of the patient and staff were
