A static pressure accuracy test device and test method based on pressure dynamic balance

Abstract

A static pressure accuracy testing device based on pressure dynamic balance, comprising: an air pump; an electronic sphygmomanometer, a pressure gauge and an air release valve connected to the air pump through a trachea, and the air pump is electrically connected to an adjustable DC power supply. By manually adjusting the voltage of the adjustable DC power supply, it gradually increases from the initial pressure of 0V. At this time, the air pump also starts to work slowly, and the pressure in the pipeline rises slowly. The pressure gauge can display the pressure value in real time to control the inflation rate of the air pump. Stop adjusting the voltage, the pressure in the pipeline rises more and more slowly. When the inflation rate of the air pump and the deflation rate of the deflation valve reach a dynamic balance, the air pressure in the pipeline is stable, and the pressure gauge can display the pressure value in real time, so that the static pressure can be judged. Accuracy of electronic sphygmomanometer measurements under pressure.

Description

technical field [0001] The invention relates to a pressure accuracy test device, in particular to a static pressure accuracy test device and a test method based on pressure dynamic balance. Background technique [0002] Hypertension is a chronic disease characterized by continuous increase in arterial blood pressure, which often causes lesions in heart, brain, kidney and other important organs, leading to more serious consequences, such as coronary heart disease, cerebrovascular disease, hypertensive heart disease , chronic renal failure, etc. In my country, one-eighth of the population is threatened by high blood pressure, and high blood pressure has also become the dominant risk factor for human death. The necessity of long-term blood pressure control is beyond doubt. To control blood pressure, you must first understand your own blood pressure. Fortunately, blood pressure measurement technology is now relatively mature, and there are all kinds of blood pressure monitors, ...
