Blood pressure meter

Blood pressure meter

The working principle of the blood pressure meter is different according to the principle of the Korotkoff sound method and the oscillation method. The Korotkoff sound method measures the blood pressure by listening to the sound emitted by the blood flowing through the blood vessels; the "oscillating method" causes the blood vessels in the arm band to vibrate due to the action of the blood flow from the heart. The oscillation method is a method of detecting the blood pressure value of the waveform of such vibration. Not affected by outside noise. Electronic sphygmomanometers are mainly used in hospitals abroad. Because the stethoscope is not used, the arm strap is easy to operate and can be used by anyone.

The classification of blood pressure meter can be distinguished according to the measurement method and working principle: according to the different measurement methods, the blood pressure meter can be divided into two types: wrist blood pressure meter and arm blood pressure meter; according to different working principles, it can be divided into three. Species: traditional mercury column (mercury) sphygmomanometer, barometer (spring) sphygmomanometer, electronic sphygmomanometer. The blood pressure meter has functions such as measuring blood pressure and monitoring for 24 hours.
