Transportable high-performance air barrier unit designed by HVAC system engineers

Taikisha has developed “Air Infection Block Plus,” which ensures Healthcare workers operability in medical activities while reducing the risk of droplet transmission while caring patients with COVID-19. Air Infection Block Plus drastically reduces the contamination concentration via micro-droplet and droplet nuclei by air-flow control technology. The air flow curtains covers healthcare professionals providing auxiliary jet and active induction air flow into air-inlets maintaining sufficient Airflow cutoff. Air Infection Block Plus also prevents the occurrence of secondary infection by adopting an additional aid of sterilization effect on HEPA filter.

Development Purpose

As the number of infections by Novel corona virus increases, several cluster infections in hospitals have also been found.
Taikisha proposed a virus infection prevention system for Healthcare workers from the viewpoint of social contribution through innovative technology development focused in air-conditioning markets for many years.
“Air Infection Block Plus,” a transportable high-performance air barrier unit that can reduce the risk of exposure to the virus infection simply through installation in a required place such as when Healthcare professional performs medical procedures with patients in face-to face or when medical examinations via specimen collection for PCR tests, etc. Air Infection Block Plus protects healthcare professionals with a "unidirectional air flow" that has a centralized configuration of the air curtain and the air inlet on the patient’s side. It prevents the spread of virus by partial virus-removal dust collection system and recirculating filtered air in closed or crowded places.

Features and Overview of Air Infection Block Plus

Air Infection Block Plus blocks bidirectional air migration with the air curtain positioned at the opening of the partition between patient and the healthcare worker. Combined air flow technology ; the auxiliary jet and active attraction to the air inlet-, Air Infection Block Plus blocks infected individual’s exhaled breath and coughs coming thorough the partition to the upper bodies of healthcare workers who are managed to take care of patients in face-to-face. Moreover, by adopting the sterilization/enzyme HEPA filter PACMAN※1, sterilization and virus inactivation※2 by lytic enzymes can be expected from this partition-type air barrier unit. As one of the features of this unit, which has no hood, small and space saving. Easy to move and install. Active ventilation on the patient's side can reduce the potential risk of infection to 1/10 of the recommended contamination concentration level even when a healthcare professional assists the patient on patient’s side. The sliding function of the transparent resin panel in the central opening ensures the adjustment of the opening according to the treatment posture. The body of the unit is equipped with a pre-filter, which extends the longevity of the HEPA filter. It offers an additional advantage in increasing the ventilation frequency so the entire room air can be kept clean.
