Founded in 2002, Lexin is a cooperative brand of the National Center for Cardiovascular Diseases and one of the few core suppliers of Braun in Germany, which is enough to reflect its manufacturing technology and quality management. At present, it focuses on the two major directions of "wearable smart devices" and "mobile medical care", involving sports bracelets, smart scales, wireless interconnected blood pressure monitors and related Internet products, and is also the second wearable device sales company in China after Xiaomi. The wrist model also has a 1117 on sale, which is the only wrist blood pressure monitor of all brands with an orange backlight.
 
Like iHealth, Lexin's blood pressure monitor also pursues intelligence and electronic, but unlike iHealth, which focuses on the combination of mobile phones and blood pressure monitors, Lexin seeks to expand the function of the blood pressure monitor itself. Although the earliest launch of i2 is still a traditional sphygmomanometer design, it has a stocky host, a backlit orange high-definition large screen, and rich functionality, but it has begun to be interconnected with WeChat, and the price of 168 yuan is also very cost-effective. Later, the i8 added the function of "chat", and the panel is equipped with a voice button, which can realize remote intercom with parents or doctors.
 
Lexin's innovation process in the form has not taken the detour of iHealth, for the elderly users to considerate, i8 retains the due large screen display, starting from the measurement path, using a double-tube design, the pressurization and pulse detection linear dual-channel shunt, only capture the pulse signal, so that even if the most basic FFT filtering algorithm is used, you can also get accurate results. With Lexin's self-developed DPDA intelligent pressurization method, different pressurization values are set according to different users, and the error is controlled within 3mmHg, and the accuracy of i8 has also passed the CFDA China Food and Drug Administration medical certification standard, and its price is 499 yuan.
 
However, Lexin also has a common problem with smart hardware, and when it first starts to use, it has to go through a series of binding settings and other operations, and elderly users may need to get started with the patient guidance of young people.
