BARRIHOOD and BARRIFLOW Clean Booths for Medical Use

3 Good Health and Well-Being

7 Affordable and Clean Energy

11 Sustainable Cities and Communities

These booths are designed to reduce medical workers’ and patients’ risk of infection from new strains of influenza and novel coronaviruses via droplets.
New strains of influenza are transmitted primarily by droplets. Physicians are at especially high risk of contracting these diseases because they are exposed to droplets from coughing and sneezing when they examine patients in close proximity.
These booths provide safe environments for physicians to conduct examinations. They also reduce the risk of infection of nurses and other medical personnel in the area.

Joint development

These booths were developed in collaboration with Hidekazu Nishimura, Director of the Virus Research Center at Sendai Medical Center.
The Virus Research Center was established in 1963 and is one of the few clinical virology research institutions in Japan.
The facility’s website contains information about BARRIFLOW III and BARRIHOOD.

Case study

This case study involves BARRIFLOW III medical clean booths.
In 2020, we delivered the booths to the Otani-Clinic as Covid-19 was spreading around the world.
We asked Director Yoshio Otani about the process of installing the booths and his impressions of them.

Functions and features

Curtains with optimal shapes as determined by airflow analysis prevent droplets from coughing and sneezing from reaching physicians.
Optimally shaped curtains provide safe, comfortable examination environments for patients, whether they are sitting or lying down.
HEPA filters and large airflow fans clean entire examination rooms.
The booths reduce physicians’ risk of infection by optimizing the positioning of the physician and the patient.
Simply reposition the vinyl curtains to easily change the pressure from positive to negative or vice versa.
Compact storage size and simple assembly make the booths easy to set up and put away in any situation.

These booths are delivered with positive or negative pressure, whichever the customer specifies.
These booths can be reconfigured in clinical settings with a few simple steps.

Positive pressure

In the event of a pandemic involving a new strain of influenza or some other disease, physicians can enter the clean space inside positive-pressure booths to reduce their risk of infection and safely examine large numbers of patients.

Negative pressure

In the early stages of an outbreak of a new strain of influenza or some other disease, patients can be quarantined inside negative-pressure booths to allow physicians to safely examine them from outside and prevent transmission to medical personnel and other patients.
