The present invention relates generally to a mobile isolation ward, and more particularly to a mobile isolation ward in which a main body made of a glass fiber reinforced plastic material in a compact size is provided, the inner surface of the main body is surface-treated with an eco-friendly polymer paint, a fixed lighting window finished with silicone is provided in the right side of the main body, and an air purifier equipped with a 13-level or higher high-efficiency particulate air (HEPA) filter is installed on one side of the inside of the main body.
Recently, the rate of increase in the number of patients infected with COVID-19 has risen sharply, and the locally prevalent community infection is spreading across the country. Due to this, intensive care beds and general beds used to treat COVID-19 patients are substantially filled up, resulting in a large-scale shortage of beds.
Due to this situation, COVID-19 patients cannot be isolated and treated and the number of patients waiting at home increases, so that there occurs a crisis situation in which the problem of treating these patients arises and the possibility of family-to-family transmission increases. As a result, the tragedy in which many severe COVID-19 patients die alone at home because they do not receive timely treatment is becoming a reality.
Accordingly, in order to isolate and treat a large number of patients in preparation for an infectious disease such as Corona 19, it is necessary to secure sufficient accommodation spaces such as auditoriums and gymnasiums in the community and to provide a number of mobile isolation wards in the accommodation spaces.
However, since the existing mobile isolation wards have a large size and a number of pieces of unnecessary equipment are installed therein, there is a problem in that it takes a lot of time and money to manufacture such mobile isolation wards.
Furthermore, the existing mobile isolation wards have a problem in that contaminated air inside the mobile isolation wards may leak to the outside through a gap formed in connection with a door or a window. In addition, there is a problem in that the existing mobile accounting wards cannot completely filter out droplets contained in contaminated air therein.
Moreover, the existing mobile isolation wards do not have a system for controlling an environment inside the ward according to a patient's condition, so that there is a problem in that it is not possible to provide a customized medical environment optimized for each patient.
