PulseWave Blood Pressure Measurement is the World Most Accurate and the Latest Generation Blood Pressure Measurement Technology which independently invented by Shenzhen Raycome Health Technology Co., Ltd, It obtained invention patents in 5 countries (Chinese Patent No. ZL 2010 1 0247968.6, Japanese Invention Patent No.5591404, Korean Invention Patent No. 10-1460922, Russia Invention Patent No.2546918, South Africa Invention Patent No.2013.00996) and under application in more than 40 countries all over the world.
Raycome PulseWave BPMonitors past over millions of times‘ clinical testing,now applying in more than 1400 top first-class and upper first-class hospitals in China.
Raycome PulseWave BloodPressure Monitoring Devices was granted by National Emergency Staff Center as the assigned BP Monitors supplier,was assigned and applied in Chinese Aircraft Carrier,won the top 50 Biotechnology Innovation Enterprises in Guangdong-HongKong- Macao Bay Area,was granted by National Hypertension Big Data Joint Laboratory as the assigned Blood Pressure Monitors supplier,was listed in China Foreign Aid Medical Product catalogue.Co-operated with the National Center for Cardiovascular Disease as its designated partner and sole partner for Sphygmomanometers products.
It imitates mercury BP Monitor.
But it's better than mercury BP Monitor.
Because it has 2 airbags with 2 tubes and 2 sensors.
Upper airbag functions as pump bulb ,lower airbag functions as the mercury column to detect pulse wave.
The results come from physics and maths algorithm, not by human judgement via hearing and vision.
H1 stands for the 1st pulsewave amplitude
H2 stands for the 2nd pulsewave amplitude
Pss1 stands for the airbag pressure data of H1
Pss2 stands for the airbag pressure data of H2
Pss0 stands for the airbag pressure data when pulsewave amplitude is 0.
So,we can get below equals:
Therefore,Pss0 is the highest pressure (SBP)
When start to measure with the pulsewave cuff, the upper airbag gets enough pressure to block the blood flow of the brachial artery, then it gradually released the pressure of upper airbag until the moment that the blood flow rushes into vessel (we call this moment as Pss0),at this moment, the pulse will generate an intensity wave,this wave compared with the airbag pressure wave,there will be a LINER DATA,we call Pss0 as the highest pressure,that is SYSTOLIC PRESSURE (SBP).
When blood rushes into vessel,with the pressure released from the upper airbag, there is a time delay for blood flow from heart to brachial artery , and the moment when this time delay gradually approaches zero,it means the blood can flow freely without any external pressure,just flow by the heart beats pressure,this moment stands for the lowest blood pressure (DBP),we call it Psz0.
Psz1 & Psz2 & Psz3 & Psz4 : Separately stands for lower airbag pressure data (which also means the pulsewave pressure data) at each SBP points.
T1 & T2 & T3 & T4 : Separately stands for the TIME DELAY of pulsewave according to Psz1/2/3/4.
PszA & PszB : Separately stands for lower airbag pressure data when upper airbag pressure data is smaller than DBP data.
TA & TB : Separately stands for the matching time dalay.
Psz0 stands for upper airbag pressure data at DBP point
T0 stands for the matching pulsewave time delay on this DBP point.
So,we'll get below equals:
(Psz1-Psz0)/(T1-T0)= (Psz2-Psz0)/(T2-T0)= (Psz3-Psz0)/(T3-T0)= (Psz4-Psz0)/(T4-T0)
Therefore, Psz0 is the lowest pressure (DBP)00
1.By using a Three-way-pipe, connect the pressure tube of Pulsewave BP Monitor and mercury sphygmomanometer, then connected to the pressure port .
2. Put the stethoscope under the edge of cuff, keep a distance of 2-3 cm from chelidon
3.When measuring, use a cloth cover the screen, read the value from the mercury sphygmomanometer, then compare the results from two BP Monitors.
The results are consistent
The Pulsewave BP Monitor is definitely accurate and reliable
Keep calm/peaceful for 3~5 minutes before measurement
Keep silent during measurement,no talking
Take off your backpack
Take off your thick coat
Do NOT roll your sleeve to upper arm
Keep the distance between testing table and chair at 25~30cm
Keep elbow pressing the blue button
Do Not shake legs
