Something About Sphygmomanometer

The sphygmomanometer mainly includes auscultation sphygmomanometer and oscillometric sphygmomanometer The auscultation method is further divided into artificial auscultation and automatic auscultation. Mercury sphygmomanometers and spring-type sphygmomanometers are early artificial auscultation sphygmomanometers. The current artificial auscultation methods include digital sphygmomanometers, sphygmomanometers, and sphygmomanometers. , LCD blood pressure monitors, etc.; auscultation automation technology is difficult.

The automation of Koch's auscultation method will be the main direction for the development of sphygmomanometer. The automatic auscultation sphygmomanometer will make blood pressure measurement more convenient and accurate. The oscillometric method is also called the oscillation method. Simply speaking, it is to obtain the oscillating waves generated during the deflation process. The blood pressure value is converted by a certain algorithm. The vast majority of electronic sphygmomanometers are designed using oscillometric principles. The electronic sphygmomanometer has upper arm type, wrist type, and finger type.
