Take a video of your face and measure your pulse, etc. Development of smartphone apps such as Chiba University October 15, 19:39
In order to improve the quality of "online medical care", which is attracting attention as a countermeasure against the new coronavirus, research groups such as Chiba University accurately correct complexion and measure pulse and respiratory rate simply by taking a video of the face. We have developed an app for smartphones that can be used.
The new app was developed by a research team led by Associate Professor Tokumichi Tsumura of Chiba University Graduate School, who researched to make up for the problems of color variation in images and the small amount of information when interviewing online medical examinations. I have been advancing.
With this app, when a patient takes a picture of the face or tongue with a dedicated color chart, the color of the image is automatically corrected, which can be used as a reference for doctors to judge their physical condition and symptoms. ..
In addition, by applying the technology to project hemoglobin that carries oxygen in the blood on an image, when a patient takes a video of his or her face for 30 seconds, the pulse rate can be measured based on the increase or decrease in the amount of hemoglobin.
Furthermore, by capturing slight changes in the heart rate interval, it is possible to grasp the respiratory rate and the balance between the sympathetic nerve and the parasympathetic nerve, which is useful for stress checks.
Keiko Ogawa, a clinical professor at the Department of Kampo Medicine, Kanazawa University Hospital, said, "If you use online medical care well, you can reduce the risk of infection, and if you are interested, you can receive medical care immediately, and early symptom detection. It will lead to. "
In the future, the research team wants to introduce the application to health centers and hospitals on a trial basis and aim to spread it, and Associate Professor Tsumura of Chiba University said, "It is necessary to accumulate data in the future, but the next spread of the new coronavirus infection. I would like to provide the technology properly so that medical collapse does not occur in preparation for it. "
