A sphygmomanometer is an instrument for measuring peripheral blood pressure. There are two types of auscultation sphygmomanometers and Shibo sphygmomanometers. Auscultation sphygmomanometers are further divided into manual auscultation and automatic auscultation. Blood pressure is the abbreviation for systemic arterial blood pressure. The principle of blood pressure is that when the blood flows in the blood vessel, it acts on the pressure of the blood vessel wall, which is the power to push the blood to flow forward in the blood vessel. When the ventricles of the heart partially contract, blood is pumped from the ventricles into the arteries, and the pressure of the blood against the arterial walls is at its highest, called systolic pressure. When the ventricle is diastolic, the arterial blood vessels elastically retract, and the blood continues to flow slowly forward, but the blood pressure drops, and the pressure at this time is called the diastolic pressure. The measurement principle of the sphygmomanometer can be divided into direct measurement method and indirect measurement method. The direct measurement method is also called the invasive measurement method, that is, the blood pressure is measured after a catheter is placed in the blood vessel through a puncture. The indirect measurement method is also called the non-invasive measurement method, which is the various blood pressure measured on the body surface by using various sphygmomanometers commonly seen in clinical practice.
