Description
Technical Field
The present invention relates to the field of electronic blood pressure meters, and more particularly, to a method, an apparatus, a system, and a computer program for detecting arteriosclerosis.
Background
Medical treatment is closely related to everyone and is also a hot spot direction of global concern. Arteriosclerosis is a systemic disease, and can cause a series of serious problems such as stroke, angina pectoris, myocardial infarction, renal artery stenosis, lower limb artery occlusion, even aortic dissection and the like. People with arteriosclerosis seem to be more and more frequent, but arteriosclerosis is not usually found easily.
Arteriosclerosis is also usually related to some basic disease factors such as hyperlipidemia, hypertension, diabetes and the like, and causes blood vessel stenosis, thereby causing insufficient blood supply. The blood pressure and arteriosclerosis are causal to each other, and a vicious circle is formed. Firstly, the blood pressure is too high, the intima of the blood vessel is damaged by the impact of blood flow on the blood vessel wall, and after the function of the endothelium is damaged, lipid in the blood is more easily deposited on the blood vessel wall, so that the occurrence and the development of arteriosclerosis are promoted. On the contrary, arteriosclerosis inevitably reduces the elasticity of blood vessels, increases the resistance of blood vessels, and causes the increase of blood pressure. Another cause of hypertension due to arteriosclerosis is renal hypertension caused by the kidney's insufficient blood supply and reflex secretion of blood pressure-raising hormones due to the decrease in vascular elasticity.
When the blood pressure is measured, the elasticity of the artery blood vessel can be seen in the change of the pulse amplitude after being pressed, the change trend of the arm artery compressed by the inflation of the air bag during the blood pressure measurement from being pressed to returning to the normal state can reflect the elasticity of the artery, the better the elasticity of the artery is, the larger the change amplitude is, and the obvious maximum value is provided, the poorer the elasticity of the artery is, the gentler the change trend of the pulse wave is, and even the obvious maximum value is not provided, because the artery with better elasticity is easier to return to the normal state from the pressed state, and the artery with poorer elasticity returns to the normal state slowly.
The arteriosclerosis treatment needs to be detected in advance, well prevented and well controlled for complications. However, most people do not know the risk of arteriosclerosis and do not perform arteriosclerosis detection, and on the other hand, the process of the arteriosclerosis detection flow is complex and expensive. The existing sphygmomanometer on the market is mainly used for measuring blood pressure and heart rate and does not have the function of detecting arteriosclerosis.

The second stage is that when the human heart contracts, the pressure in the artery rises, and in the middle stage of the heart contraction, the pressure in the artery is highest, and the pressure of blood on the inner wall of the blood vessel is called systolic pressure, also called high pressure stage. In the high-pressure stage, because the pressure of the air bag is high, the amplitude of the pulse wave curve is relatively large, a maximum value is found from the amplitude amplitudes and is taken as a second maximum value, the second maximum value is weighted, the weighting coefficient is preferably 0.8, so that a peak value near the second maximum value is obtained and is taken as a second pulse wave peak value, and the blood pressure value corresponding to the second pulse wave peak value is taken as a second blood pressure value.

and the control calculation function is used for weighting according to the first maximum value and the second maximum value to obtain a first pulse wave peak value and a second pulse wave peak value, further obtaining a first blood pressure value and a second blood pressure value corresponding to the first pulse wave peak value and the second pulse wave peak value, and comparing according to the absolute value of the difference between the first blood pressure value and the second blood pressure value and a first judgment threshold value and a second judgment threshold value to obtain an arteriosclerosis index.
