In a pandemic situation like COVID-19, the demand for negative pressure wards has dramatically increased. It is possible to rapidly build an isolation ward by combining air tents, functional panels, and a negative pressure frame. The design addresses the requirements of functionality, cost and efficiency. In addition, it supports the emotional needs of patients and medical staff. The unique airflow structure guarantees bio-safety maintaining the pressure differences among hot, warm and cold zone in the ward. With the use of air tents, the whole ward can be shipped by airplane in an emergency.
