The 2022 Beijing Winter Olympic Games is under way. As the first referral hospital for medical security in Zhangjiakou competition area of the Winter Olympic Games, Chongli Hospital of the Third Hospital of Beijing Medical College undertook the treatment of Olympic patients during the events of 51 events in 109 Olympic events in the Winter Olympic Games. Getting on the bus means "admission". Through the seamless guidance and connection of the command and dispatching center, helicopters, robots and other "black technologies" are launched together to realize the seamless connection of all links of the snow field, the snow field clinic, the Winter Olympic Village, transportation and hospital, and the scientific and technological Winter Olympic Games are displayed everywhere. (economic information daily, February 8) The rigorous organization, high efficiency and high quality of medical security in this winter Olympic Games are amazing. The medical staff responsible for the on-site support task carry portable monitoring equipment and medical equipment, which can quickly check the patients and accurately grasp their injury and condition at the first time; Ambulances and helicopters equipped with advanced communication and intelligent equipment are well-equipped mobile emergency rooms; The top expert team of the hospital can provide high-quality diagnosis and treatment services for the patients on the field at any time, as if these expert teams were on the scene. It is worth mentioning that robots have become an important "assistant" of medical security for the Winter Olympic Games. For example, Noah hospital logistics robot can transport drugs, specimens, injections, etc., realize zero contact handover in the whole transportation, and the whole material transportation data can be traced. Noah's "light vaccine door" can realize man-machine coexistence and precise killing. It can eliminate up to 99.99% of coronavirus and complete the whole killing in 150 seconds. In the novel coronavirus pneumonia epidemic is still spreading rapidly in the global context, this winter Olympic Games can still become a very strong security event. Besides the key role of closed loop management and other measures, the application of "black science and technology" in epidemic prevention is also important. Portable medical devices, 5g ambulances, medical robots, remote consultation and remote operation, etc. Although these scientific and technological means and devices have existed in the past, such "black technologies" entering the Winter Olympic Games have made a lot of technical improvements and become more mature and practical. Only a number of portable medical devices are of great mass production and promotion value, It can become the standard configuration of first aid personnel in the future. The rapid killing technology of coronavirus participated by robots has strong practical significance and practical value for current and future epidemic prevention and control. More importantly, it is one thing to use medical "black technology" alone or locally, while collaborative and all-round use is another. Medical "black technology" products are like the raw materials of dishes. Only by using these "black technologies" cooperatively and comprehensively can these raw materials be made into a table of delicious food. The medical security of this winter Olympic Games reflects the superb and strict overall planning ability of medical "black technology". All medical security links are seamlessly connected and all high-tech products are closely coordinated to make it a complete system, which is a more commendable change. The medical security model carefully designed for this special scene of the Winter Olympics can also be used for reference to other similar scenes in the future, so that emergency disaster relief, medical security for large-scale activities and daily medical first aid can have higher quality, faster speed and better effect. We can also learn from relevant technologies and management in terms of remote consultation and cooperation among medical institutions of the medical consortium. Many good practices of this winter Olympic Games are worth carrying forward. The medical security model is undoubtedly a valuable asset. Inheriting these good practices is expected to greatly improve the level of first aid and medical security. (outlook new era)
