Abstract: A mobile hospital system can be moved by tractors, helicopters, railway locomotives and/or sea vessels and provide comprehensive diagnoses and medical treatments to casualties and patients. A plurality of container wagons functionally operate as part of a hospital and are moved appropriately to set up a comprehensive hospital system by connecting the plurality of container wagons on site, some of the container wagons being supplied with water, power and fuel oil from a water supply wagon, a power generation wagon and an oil supply wagon, respectively. With such an arrangement, a comprehensive hospital system can be set up by connecting the plurality of container wagons on site in a region hit by a natural disaster or a harsh military dispute so that it can provide relevant medical services to a large number of patients including causalities.
