From March, NTT DoCoMo and Tokushima Prefecture will introduce a telemedicine support system using 5G and DoCoMo Open Innovation Cloud for high-definition video transmission at Tokushima Prefectural Central Hospital, Miyoshi Hospital, and Kaifu Hospital. The operation is scheduled to start in early 2021. The system uses a highly secure closed network created by the DoCoMo Open Innovation Cloud to display medical device data and high-definition images from cameras at high speed and with a large capacity of 5G (5th generation mobile communication system) in a remote prefectural area. Allows transmission between hospitals. In addition to the images of patients and doctors, the burden on doctors can be reduced by synthesizing medical device data such as echoes and electrocardiograms / endoscopes and transmitting them on a single screen. Based on the results of demonstration experiments conducted at Tokushima Prefectural Central Hospital and Kaifu Hospital from January to February 2020 and the opinions of patients and doctors, we are constructing by improving operability and system improvements such as video and voice synthesis. .. For video distribution, the high-definition video distribution system provided by Soliton Systems will be used. By utilizing this system, for example, it is expected that the travel time of both specialists and patients who have been to remote areas for medical treatment will be reduced, and that medical care equivalent to that in urban areas will be available in each region. In addition, emergency / home-visit medical support can be provided by installing it in a doctor car. In addition, it is expected to be used in a wider range of applications in the future, such as providing guidance to young doctors by transmitting images of medical practices by skilled specialists and using it for distance learning that connects prefectural general nursing schools and prefectural hospitals.
