Pulse wave sphygmomanometer

Pulse wave sphygmomanometer is a non-invasive precision sphygmomanometer successfully developed by Dr. Wu Xiaoguang, a graduate of Tsinghua University, and his research team in 2012. It is another breakthrough in the blood pressure measurement technology following the invasive blood pressure measurement method, Koch's tone measurement method, and the oscillometric method, and solves the problem of difficult to express the real blood pressure value of the non-invasive blood pressure measurement from the invention of Koch's tone sphygmomanometer to the present time, due to the current concept and the peculiar measurement method. Expression of the real blood pressure value of the problem, make up for the international non-invasive precision blood pressure measurement of the field of blank products.

Technical principle

Pulse wave sphygmomanometer adopts pulse wave detection method to replace the Koch's tone method (hearing is false, seeing is not believing), adopts multi-point measurement to replace single-point measurement, and utilizes the intrinsic connection and change rule between points near systolic and diastolic blood pressure points, and adopts the approximation and fitting calculation method to calculate the real systolic and diastolic blood pressure values, and realizes the continuous measurement of the discontinuous events, i.e., the continuous measurement of the blood pressure between two jumps of the heart can be measured. Measure the blood pressure value between two beats of the heart. All measurements are performed without human intervention, avoiding subjectively introduced errors. The calculation of blood pressure value relies on the intrinsic connection and change law between the points near the systolic and diastolic blood pressure points, rather than based on empirical statistics, which avoids the measurement errors caused by individual differences.

Technical features

Advanced: The pulse wave sphygmomanometer adopts the fourth generation of pulse wave blood pressure measurement technology which has been patented.

Accurate: The Pulse Wave Sphygmomanometer adopts the pulse wave detection method instead of the Koch sound method (hearing is not believing, seeing is not believing), and the pulse wave can truly represent the state of blood flow. The use of multi-point measurement instead of single-point measurement avoids the false hypotension caused by the Koch sound method due to the unsynchronized blood flow pulse and sound.

Pulse wave sphygmomanometer, using the intrinsic connection and changing law between the points near the systolic and diastolic blood pressure using approximation and fitting of the calculation method to calculate the real systolic and diastolic blood pressure values, realizing the continuous measurement of discontinuous events, that is, it can be measured between two beats of the heart's blood pressure values, rather than based on empirical statistical data, to avoid the measurement error caused by individual differences. Measurement accuracy can be controlled within ±2mmHg.

Convenient: The smart chip embedded in the pulse wave sphygmomanometer can simulate each step of the blood pressure measurement process automatically without manual operation, which is not only convenient, but also avoids the error caused by human intervention.

What brands of home blood pressure monitors on the market use pulse wave technology?

According to market research results, the current pulse wave technology used in home blood pressure monitor manufacturers are not many, are some of the old and strong manufacturers, such as Tencent and Jingdong jointly invested in the PICOOC intelligent blood pressure monitor (price 150 or so), imported from Japan, OMRON high-end series of products (price 400 or so).
