Accordingly, protectors, etc. for medical staffs are relatively simplified, so it is possible to reduce a burden on medical staffs and induce more precise operations. Further, since the isolation space is formed to fit the body of a patient, the surrounding space can be more widely used.

Further, it is possible to considerably increase the number of substantial negative pressure beds using existing common beds, etc., by using the present invention. Accordingly, it is possible to effectively deal with rapid spread of infected people through the present invention.
