A hospital refers to a medical institution that, in accordance with laws, regulations and industry norms, provides patients with necessary medical examinations, treatment measures, nursing technology, consultation services, rehabilitation equipment, treatment and transportation and other services, with the main purpose of saving lives and healing the wounded. Its service objects include not only Symptomatic patients and injured persons, including the elderly who are unable to take care of themselves or whose activities are limited and who are dependent on medical care, the severely ill and injured persons who are assessed by forensic experts as being dependent on medical care or whose condition is unstable and require long-term rehabilitation and frequent observation and examination, or other specific situations and groups of people, such as healthy people (such as pregnant women, mothers, newborns) and completely healthy people (such as people who come to the hospital for physical examination or oral cleaning). When it was first established, it was for people to take refuge, and there were also entertainment programs to make people come to the hospital. It was intended to provide comfort to patients and entertain them. Later, it gradually became a specialized institution for receiving and treating patients.
