The COVID-19 pandemic has made a huge impact on the healthcare scenario of the world. Due to its easy transmissibility, it has affected a majority of the population in a short time. Healthcare staff like nurses and doctors are at an even higher risk of infection because of their prolonged and repetitive interaction with patients. Isolation chambers can be an integral part of Vital care Units and Intensive Care Units (ICUs). Viral & bacterial matter can be present on surfaces of objects in regular use. A negative pressure environment can drastically curb the spread of viral matter in air. In this study, we have proposed a double-door isolation room model with air pressure differential control to prevent spread of the virus to the outside world. Our model aims to contain the viral air and eliminate airborne pathogens using High Efficiency Particulate Air (HEPA) filters and Ultraviolet (UV) light, along with antimicrobial surface coatings. The isolation chamber has prefabricated panels for short installation time, and are made with low-cost materials.
