Description
Technical field
This utility model relates to a kind of electric sphygmomanometer, especially a kind of full-automatic electric sphygmomanometer based on Ke Shi sound measuring method.
Background technology
Blood pressure is blood while flowing in blood vessel, the pressure of vasoactive wall, and it is to promote blood mobile power in blood vessel.Ventricular systole, blood flows into tremulous pulse from ventricle, and now blood is the highest to the pressure of tremulous pulse, is called systolic pressure.Ventricular diastole, arteries elastical retraction, blood still slowly continues to flow forward, but blood pressure drops, pressure is now called diastolic pressure.The medical apparatus of measuring systolic pressure and diastolic pressure is called sphygomanometer.
Traditional sphygomanometer mostly is mercury sphygmomanometer, and its principle is heard significant Ke Shi sound for healthcare givers in Measure blood pressure process, observes the pressure of mercury column indication simultaneously, reads diastolic pressure and systolic pressure.This method is called domestic and medical first-selection for a long time, but it uses the comparatively personnel of specialty.In addition country is more and more stricter to the use restriction of hydrargyrum, causes this type of mercurial sphygmomanometer to withdraw from the market completely gradually.Nowadays used more electric sphygmomanometer, its principle is not too identical with mercury sphygmomanometer, and most products are used oscillographic method Measure blood pressure.In the measuring process of oscillographic method, adopt pneumatic sleeve to block upper arm artery blood flow.Due to the effect of Hemodynamics on Pathogenesis of heartbeat, on gas sleeve pressure by overlapping pressure oscillation of synchronizeing with heartbeat, i.e. pulse wave.When gas sleeve pressure is during far above systolic pressure, pulse wave disappears.Along with oversleeve pressure drop, pulse starts to occur.When oversleeve pressure is from dropping to systolic pressure higher than systolic pressure when following, pulse wave can increase suddenly.During to mean pressure, reach maximum.Then with oversleeve pressure drop, decay again.Oscillographic method blood pressure measurement carrys out estimated blood pressure according to the relation between pulse wave amplitude and gas sleeve pressure.Corresponding with pulse wave maximum is mean pressure, and systolic pressure and the diastolic pressure respectively ratio of corresponding pulse wave peak swing are determined.
The feature of oscillographic method is to assist without professional medical personnel, simple and quick.But itself more Dependent Algorithm in Precision of oscillographic method, and in degree of accuracy, there is the probability of error.
In view of this, be necessary existing electric sphygmomanometer to be improved to address the above problem.
