Blood Pressure Monitor

A sphygmomanometer is an instrument that measures blood pressure, also known as a blood pressure monitor. Sphygmomanometers mainly include auscultation sphygmomanometers and oscilloscopic sphygmomanometers.
The main sphygmomanometers of the auscultation method are: mercury sphygmomanometer (manometer), spring gauge sphygmomanometer (calender sphygmomanometer, photostensitive sphygmomanometer, liquid crystal sphygmomanometer, etc.
The oscilloscopic method, also known as the oscillation method, its principle is to obtain the oscillating waves generated during the degassing process, and the blood pressure value is converted by a certain algorithm. The vast majority of electronic sphygmomanometers are designed using the oscilloscope principle.
