Background
The main principle of the sphygmomanometer is a process of measuring the blood flow pressure during a period when the pressure is applied by pressurizing air to press a local artery and the pulsation of the local artery is stopped. The measurement principle of the sphygmomanometer can be divided into an auscultation method and an oscillography method.
The auscultatory method is also called Korotkoff sound method, and is also classified into artificial Korotkoff sound method and electronic Korotkoff sound method. The artificial Korotkoff sound method is a method which is commonly seen by doctors and nurses and is used for measuring blood pressure by using a pressure gauge and a stethoscope; the electronic Korotkoff's sound rule is a Korotkoff's sound measuring method using electronic technology to replace doctors and nurses. The principle is that a cuff is wound around the upper arm, and the pressure of the cuff acts on the brachial artery. The cuff air is adjusted to change the pressure and the sound of the pulsation is heard by the stethoscope, so as to obtain the systolic pressure and the diastolic pressure. The oscillography, also called the oscillation method, is a relatively advanced electronic measuring method developed in the 90 s of the 20 th century, and the principle thereof is that the inflation quantity of a cuff wound on an upper arm is automatically adjusted, the pressure is changed, blood flow has certain oscillation waves through blood vessels, the blood flow is received by a pressure sensor and is gradually deflated, the pressure and the fluctuation detected by the pressure sensor are changed along with the change of the oscillation waves, the moment with the maximum fluctuation is selected as a reference point, on the basis of the reference point, the fluctuation point with a certain value is searched forward to be the systolic pressure, the fluctuation point with a certain value is searched backward to be the diastolic pressure, and the value is set differently by different manufacturers. The diastolic pressure and the systolic pressure are quantized into digital forms to be displayed to a user, so that the user can know the condition of the blood pressure.
