covid 19 is becoming a big problem day by day around the globe due to which lakhs of people died. To stop the spreading of virus, I designed a modular portable isolation facility as a cuboid structure which is made of assembly. this assembly is constructed of 3 parts. part 1 can be attached with part 2 by magnet provided in lower face. shield of assembly is made of plexiglass material which is strong and flexible and can withstand sun temperature of up to 180 degree Celsius. seating area is made of HDPE material. detachable air fan is given which gives ventilation to the patient inside box. people outside the box remain fully protected from the patient coronavirus. handle is provided in part 1 and part 3 as a mean of handling. middle window is given to open and close by handle. this box can be easily handled in hospital or home in sloppy paths. Part 3 can be easily detached and patient can sit inside it. after that it can be transported in lift. a slope is given in part 3 which is used to be used for pillow. patient can complete maximum days in isolation by using this box. it can be used in any environmental conditions. it can be used in rural places as a quarantine facility. minimum 2 people are required to assemble all three parts. no special training is required. it is cheap so rural people can also use it. this box can be easily attached inside an ambulance by magnet. so that it never bothers the patient inside the box. box is movable by the given wheels. a small hole is provided in part 1 so that air ventilation can taken place. glass of the box never become heated due to special material.
