Description

Measuring device for detecting pulse wave pressure amplitude value in cardiovascular disease

Technical Field

The utility model belongs to the technical field of medical auxiliary numerical value acquisition devices, and particularly relates to a measuring device for detecting a pulse wave pressure amplitude numerical value in cardiovascular diseases.

Background

When blood flows in a blood vessel, the lateral pressure on the wall of the blood vessel becomes blood pressure. Blood pressure is often referred to as arterial blood pressure or systemic blood pressure, and is an important vital sign. Blood pressure measurement is a main means for assessing blood pressure level, diagnosing hypertension and observing antihypertensive efficacy, and accurately measuring blood pressure is a basis for developing hypertension management in the basic layer. The general blood pressure measurement method is to wrap the upper arm with a tourniquet, fill air into the tourniquet, press the blood vessel of the upper arm, and stop the blood flow. After that, the compression is relaxed slowly, and the blood flow pressure in the compressed blood vessel is transmitted back to the tourniquet, at this time, the blood flow starts to flow in cooperation with the pulsation idle of the heart. The pressure amplitude in the pressure belt is measured by using the pressure belt to reflect the vibration of the blood vessel wall during the beating of the heart to the pressure fluctuation of the pressure belt during the pressurizing and depressurizing processes, so as to determine the blood pressure value. In general, when the pressure pulse wave increases sharply, the pressure of the tourniquet is the lowest blood pressure, and when the pressure of the tourniquet decreases sharply, the pressure of the tourniquet is the lowest blood pressure. However, the high and low blood pressure values obtained by the sphygmomanometer are generally used for judging hypertension or hypotensive symptoms, and are used for treating or improving life work and rest by proper medicines aiming at the hypertension or the hypotension, but the risk of the cardiovascular diseases is hidden due to the hypertension or the hypotension is difficult to predict.
