Telemedicine includes telemedicine consultation, telemedicine education, and the establishment of multimedia healthcare consultation systems. Telemedicine consultation establishes a brand-new connection between medical experts and patients, so that patients can receive consultation from remote experts in the same place and hospital, and carry out treatment and care under their guidance, which can save a lot of time and money for both doctors and patients. Telemedicine uses computer, communication and medical technologies and equipment to realize "face-to-face" consultation between experts and patients, and between experts and medical personnel through the long-distance transmission of data, text, voice and image information. Telemedicine is not only a medical or clinical issue, but also includes communication networks, databases and other aspects of the problem, and the need to integrate them into the network system.
The telemedicine system, which United is putting into trial operation, provides a full range of vital signals, including heart, blood pressure, respiration and so on. Timely medical support from around the globe is available during flight via a mobile communications system. Developed by the University of Maryland, the field telemedicine system consists of a field physician, a communications equipment vehicle, a satellite communications network, a field hospital and a medical center. Each soldier is fitted with a medical bracelet that tests parameters such as the soldier's blood pressure and heart rate. A GPS locator is also fitted, which helps doctors find a soldier quickly when he is injured and get him diagnosed and treated through a telemedicine system.
Some hospitals and medical colleges in China have also carried out work in this area, such as Jinshan Hospital of Shanghai Medical University, which has published a list of telemedicine consultation experts online. Xi'an Medical University in the U.S. "Bridge to Asia" funded the establishment of "telemedicine center", and successfully for the U.S. Secretary of State Albright for the U.S. telemedicine consultation demonstration. Recently, the first telemedicine center in Southwest China was established in Guiyang City - "China Goldwell Guiyang Telemedicine Consultation Center".
Telemedicine can enable patients in remote areas and without good medical conditions to obtain good diagnosis and treatment, such as rural areas, mountainous regions, field survey sites, air, sea, battlefield. It can also enable medical experts to consult with patients in different spatial locations at the same time.
