E-39 Infection Control in Hospitals : Part 5 Airborne Infection Control of Existing Consultation Room

Abstract

Medical workers use standard precautions to prevent infection. But standard precautions can't prevent airborne infections. We developed an airborne infection control system of consultation room. We used horizontal push-pull airflow to exhaust patient's cough with droplet nuclei. The push-pull devices can use in a small room. We used 0.5μm dust as alternative droplet nuclei. The concentrations of 0.5μm dust were reduced less than 1/20 when the distance of push-pull devices was 1.5m. Our infection control system can reduce the risk of airborne infection in the existing consultation room.
