Sputum Collection Negative Pressure Booth

Infection of tuberculosis germs and effect of Sputum Collection Negative Pressure Booth
Infection of tuberculosis germs occurs by sucking droplet nuclei of tuberculosis germs coughed
out by a tubercular patient and flying all around. Therefore, the elimination of infection path is
essential for the prevention against infection of tuberculosis.
The sputum collection negative pressure booth prevents dispersal of droplet nuclei coughed
out by a patient by keeping the pressure inside the booth negative. Furthermore, the HEPA filter
and UVC lamp installed in the booth eliminates the droplet nuclei floating inside the booth.
