The application of Digital Medical Technology in Navy fleet voyage is an effective means for medical treatment efficiency improvement, diagnosis capability enhancement, and realization of telemedicine at sea under special conditions. Through the establishment of remote medical center and the design of maritime telecommunications link, various biological data can be collected via technique such as sensors during the process of medical treatment at sea and transfer of the wounded. Hence, a synchronized maritime clinic data center is in place to allow for information exchange between the maritime treatment platform and the hospital on land. With the remote support of maritime medical center for treatment at sea, the advantages of flexibility, adaptability and reliability are clear. The application of digital medical technology in maritime medical treatment plays a significant role in enhancing the medical support capability.
