Desktop Air Curtain System with Virus Inactivation Function

Technology Overview

The research group has succeeded in developing the desk top air-curtain device that can generate an air wall (or air-curtain flow) to block aerosols contained in the exhalation from patients (). The air curtain flow is produced by the discharge port at the top of the air curtain system. This released flow from the discharge port is guided to the suction port at the bottom by new jet nozzle with cut-off blades to improve air curtain airflow intensity. This prevents the dispersion of the air curtain system, thus leading to the collection of all the aerosol particles emitted by humans at the suction port. The air led to the suction port is carried to the virus inactivation device, and the air irradiated with deep UV rays is carried again to the discharge port of the air curtain system.

Benefits

Enables reduction of the risk of virus exposure for patients and healthcare workers during medical procedures where it is difficult to maintain a sufficient distance, such as medical interviews, blood sampling, and treatment.
