A blood pressure meter is an instrument for measuring blood pressure, also known as a sphygmomanometer.
With the improvement of people's living standards, there are more and more people in China. Portable blood pressure, blood sugar, blood fat instrument is basically a family necessity. Xuan Li professional configuration of 0.88WH lithium battery, complete certification, small size, long cycle life.
Auscultation blood pressure apparatus includes manual auscultation blood pressure apparatus and automatic auscultation blood pressure apparatus.
Artificial auscultation blood pressure apparatus:
Traditional mercury column (mercury) type sphygmomanometer and blood pressure table
There are desktop and vertical two kinds, vertical sphygmomanometer can adjust the height arbitrarily. However, it is a little large and inconvenient to carry, and it is easy to cause mercury leakage in the process of carrying and affect the accuracy. Therefore, before each measurement, it is necessary to check whether the mercury convex surface in the scale tube is exactly at the zero position of the scale. After the measurement, the sphygmomanometer is tilted 45 degrees to the right and the switch is turned off to avoid mercury leakage.
Automatic auscultation blood pressure apparatus:
It's automatic auscultation, automatic detection of Corleone's voice and high and low pressure. This is the way forward for non-invasive blood pressure measurement.
Electronic sphygmomanometer is a blood pressure meter designed by oscillating wave. It uses electronic pressure and oscillating waves to determine blood pressure. Its advantage is simple operation, intuitive reading, just click the button will be automatically measured, the disadvantage is because of the oscilometry measurement principle has certain defects, it is difficult to identify individual differences, its accuracy has been questioned.
