Sphygmomanometers are an indispensable health product in modern homes, from old-fashioned mercury sphygmomanometers to arm or wrist-type electronic sphygmomanometers . Either way, you need to wear inflatable cuffs and arteries. Applying pressure to obtain blood pressure values ​​cannot avoid the discomfort caused by inflation and pressurization. Recently, the reporter learned from Puren Medical Group that a pulse-inducing non-invasive blood pressure monitor independently developed by Puren will be launched in April. At that time, people can wear a sphygmomanometer like a watch and perform 24-hour blood pressure health monitoring. .

The history of sphygmomanometers can be traced back to 1682. A British scientist noticed that when the artery was cut, the blood was sprayed like a pressurized water pipe. By touching it, you can feel the beat of the expired pulse. To blood pressure, this is the original model of the sphygmomanometer.
As one of the most important vital signs of the human body, blood pressure has received more and more attention as the development of sphygmomanometers. For thousands of years, the design of sphygmomanometers has ranged from simple to simple, from invasive to non-invasive. At present, mercury sphygmomanometers and electronic sphygmomanometers have been widely used in hospitals and homes, but there are still some problems that are difficult to solve. For example, the complexity of the operation of the mercury sphygmomanometer, the lack of portability, the inaccuracy of the measurement of the electronic sphygmomanometer, and the operation of both the inflation and pressurization are uncomfortable to the user.
In order to fill the gap in the sphygmomanometer market and meet the increasing market demand for wearable medical equipment, Tianjin Puren Wanhe Co., Ltd. independently developed the pulse-sensing technology, which is currently used in the field of non-invasive blood pressure monitoring, creating a non-invasive, cuffless belt. A new era of medical-grade blood pressure measurement without inflation.
The pulse-sensing technique is based on the pulse wave velocity (pwv). When the human body has high blood pressure, the pulse wave (pw) formed by the blood output from the heart in the blood vessel and the pulse wave under normal conditions. The speed (pulse wave velocity, pwv) and waveform (waveform) are different. According to this principle, combined with the data collected by the sensor and the exclusive algorithm, accurate blood pressure values ​​are obtained.
