· Precautions and working principle of digital sphygmomanometer

Precautions for the use of portable sphygmomanometer: 1. The armband should be as high as the heart, the upper arm should naturally droop, the elbow and forearm should naturally be placed on the table, and the palm should face up. Do not place your entire arm flat on the table above your heart, or place it too high on ……

· Design and development of intelligent sphygmomanometer

The working principle of the sphygmomanometer is to listen to the sound (Krotov sound) emitted by the blood when it moves in the blood vessels to measure blood pressure. The oscillation method generates vibrations in the blood vessels within the brachial girdle due to the effect of the heart delivering blood flow. The ……

· The working principle of sphygmomanometer based on oscillography

In the measurement process based on the oscillographic method, an inflatable cuff is used to block the blood flow of the trick artery. Due to the hemodynamic effect of the heart beat, the pressure that is synchronized with the heart beat will be stacked and shaken on the cuff pressure, known as pulse waves. In the trad……
