Unless otherwise indicated herein, the subject matter discussed in this section is not prior art to the claims of this application, nor is it admitted to be prior art if included in this section.

Recently, as modern people's lives have become more affluent, their awareness of health and hygiene has also increased. However, despite the increasing importance of disease prevention due to the severe acute respiratory syndrome (SARS) epidemic in 2003 and the Middle East respiratory syndrome (MERS) epidemic in 2015, the importance of quarantine has increased recently. Due to an infectious disease called coronavirus disease (COVID-19), people not only in South Korea but around the world are struggling to recognize and overcome the dangers of viruses and new diseases. As the spread of these infectious diseases continues, there is a growing awareness that no one is safe from infectious diseases, and daily preventive measures such as wearing masks, as well as sterilization of buildings and other facilities, are regularly carried out.
Infections caused by these viruses are transmitted through the respiratory tract, but the speed of infection is quite fast, and it is not easy to trace the route of infection to where and from whom the infection was transmitted. Immediate isolation is required. In particular, when a person with confirmed infectious disease visits for treatment or is hospitalized, secondary infection may occur by infecting surrounding medical staff, other patients in the hospital, or outside visitors in the hospital room. Patients with confirmed infections should be hospitalized and treated inside a negative pressure ward to prevent the air from escaping to the outside.
The negative pressure ward keeps the air pressure in the ward lower than the atmospheric pressure to block the virus contained in the air and droplets in the ward from being discharged to the outside, and the air in the negative pressure ward is , filters (generally, HEPA filters are used), etc., and filtered air is discharged to the outside. Such a negative pressure ward has air conditioning facilities that can maintain a large negative pressure, and air moves only from the outside to the inside, so there is a risk that the contamination level inside the ward will increase. system. The air conditioning facility is composed of an intake fan, an exhaust fan, and a pressure maintenance unit for adjusting the pressure, and controls the fan speed of the intake fan and the exhaust fan to make the inside of the hospital room negative pressure. can.
However, the above-mentioned negative pressure wards require considerable costs to set up and operate, and it is practically impossible to always have a negative pressure ward with a space that can accommodate a large number of confirmed infectious disease patients. Even large hospitals are reluctant to set up negative pressure wards because it is possible. Recently, many methods are being used, such as changing the ward itself into a negative pressure ward, or setting up a negative pressure ward with mobile modules to manage patients. However, there is a disadvantage that a new system must be constructed or the ward must be remodeled, so there is a large spatial and temporal constraint. There is still a cost burden because a ventilation system for air purification must be constructed in the future. Not only that, but it also cuts off physical contact when a doctor checks the patient's condition through a glass wall for installing certain equipment in a patient room or antechamber, or for non-contact medical examination. In order to install a structure such as a structure that can be used for transportation, and a structure such as a connecting passage for moving to a toilet or other places, there was a problem that this had to be installed separately.
