Pulse wave blood pressure measurement is a non-invasive precision sphygmomanometer successfully developed by Dr. Wu Xiaoguang of Tsinghua University and his research team in 2012, which has now obtained the invention patent issued by the State Patent Office of China and has applied for international patents, and the product has been launched by Shenzhen Ruiguang Kangtai Medical Equipment Co. The launch of the non-invasive precision RG-BP II pulse wave sphygmomanometer marks that the research level of China's medical devices has jumped to the forefront of the international community. Non-invasive precision pulse wave sphygmomanometer creatively adopts pulse wave detection technology, solving the problem of non-invasive precision measurement of blood pressure since the invention of Koch's tone sphygmomanometer, 106 years ago, and making up for the blank of international non-invasive precision blood pressure measurement field.
