Description

Technical Field

[0001] The present invention relates to the technical field of virtual simulation teaching, and in particular to a virtual simulation hospital teaching system. Background Art

[0002] Existing medical schools all have corresponding affiliated hospitals. When students take practical training or practice classes, they go to the hospital and conduct practical training based on the actual operation of the hospital, which enables students to better master specific time skills. However, for some medical schools that do not have affiliated hospitals or are far away from the hospital, students cannot go to the hospital to experience the actual operation of the hospital. As a result, the practical training or practice classes are not effective and students are unable to better master medical practice skills.

[0003] At the same time, the current practical training teaching process of medical and health majors has three pain points: high investment, high loss, high risk, and difficulty in implementation, observation, and reproduction. Medical schools are currently not close enough to hospital clinics and are far away from affiliated hospitals and cannot meet the urgent needs of clinical internships. Therefore, it is necessary to design a virtual simulation hospital teaching system. Summary of the Invention

[0009] Furthermore, the above scheme also includes a teaching service data server, which is set in the comprehensive medical online virtual simulation teaching system and the central server.
