1. walk-through mobile positive pressurized and negative
pressurized isolation booth for diagnosis of COVID19
- The 'mobile-type negative pressure
isolation booth', which was
developed by a public health clinic
in Busan in South Korea,
is to collect COVID-19 samples from
the suspected quickly and safely.
- In fact, medical personnel wearing
protective clothing and suspected
are in the same place. This in turn,
generates a high risk of secondary
- As a result, it took a long time to
disinfect the space in a relatively
large collection center and took a
sample from the next patient.
The air circulation using the
negative pressure device was
12 ~ 13 times per hour, which took
a lot of time to kill the virus in the
center through the aerosol.
- So, to solve this issue mentioned
above, the Negative Pressure
Isolation Booth was developed
in the form of a small booth
that only patients could enter,
and medical staff can collect a
patient's sample through a booth
hole outside. This is the Negative
- On the other hand, the Positive
Pressure method is that medical
staff is inside the booth and a
patient is outside.
- We only need to change the
gloves, and thanks to the small
booth space, the air circulation
rate of the Negative pressure
device becomes more than 400
times per hour.
- The virus is killed
within 1 minute.
