Pulse wave-based cardiovascular elasticity testing and arteriosclerosis early warning system

Abstract

The invention discloses a pulse wave-based cardiovascular elasticity testing and arteriosclerosis early warning system. The system comprises a cuff, an air pump, an air release valve, a pressure sensor and a microprocessor, wherein the air pump, the air release valve and the pressure sensor are arranged in the cuff; the air pump is used for inflating the cuff when driven by an air pump driving circuit; the pressure sensor is used for detecting pressure value of the cuff in real time; when a preset inflation pressure is achieved, an air release driving circuit is controlled by the microprocessor to open the air release valve so as to discharge air in the cuff according to a preset speed; in such process, a pressure signal of the cuff is continuously acquired by the pressure sensor, is processed through a conditioning circuit and is separated to obtain a pulse wave signal and a cuff pressure signal through a capacitive direct current blocking circuit, and the pulse wave signal and the cuff pressure signal are transmitted to two paths of A / D (Analog / Digital) converters in a microcontroller for processing respectively; and when the pulse wave signal disappears, a one-time measurement process is finished.

Description

technical field [0001] The invention relates to a pulse wave-based cardiovascular elasticity test and an early warning system for arteriosclerosis, belonging to the technical field of medical devices. Background technique [0002] With the age structure of the population aging, cardiovascular disease (CVD) has become one of the most common diseases. In the United States, half of the people who die from diseases are caused by cardiovascular diseases. It is an important disease with the highest mortality rate in developed countries. It is also a type of disease with a relatively high mortality rate in my country. The World Health Organization has listed it as It is the number one killer endangering human health in the 21st century. Cardiovascular disease is the leading cause of heart disease and can manifest as a variety of conditions, including hypertension, coronary artery disease (CAD), peripheral artery disease, arteriosclerosis, aneurysms, stroke, kidney disease, and reti...

Problems solved by technology

However, this potential risk factor can have no symptoms in its early stage, so it is often overlooked by people and misses the opportunity for early treatment

It should be said that even the treatment of the mildest hypertension and arteriosclerosis without any symptoms should be regarded as the most effective preventive measure; Detecting and diagnosing this asymptomatic arteriosclerotic condition is a tricky problem
