Background technology
Hypertension a kind ofly continues to raise as the chronic disease of main manifestations with arteriotony, often causes the pathological changes of the vitals such as the heart, brain, kidney thus cause even more serious consequence, as coronary heart disease, cerebrovascular, hypertensive heart disease, chronic renal failure etc.In China, the hypertensive threat that has eighth population to be subject to, hypertension also becomes the mortality risk factor that the mankind occupy leading position, and the necessity of long-term control blood pressure is unquestionable.Control the blood pressure that blood pressure just first will understand oneself, fortunately, blood pressure measurement technology is now comparatively ripe, various sphygomanometer is complete, especially noinvasive electric sphygmomanometer, because of the advantage that it is easy to use, cheap, has become the first-selection of domestic, medical blood pressure measurement.In order to supervise effectiveness and the safety of noinvasive electric sphygmomanometer better, there is concerned countries standard, the strict implement of industry standard etc. always.Wherein clearly mention in the industry standard of noinvasive electric sphygmomanometer will carry out static pressure feature measurement in the method for testing of repeatability, accuracy.So-called static test pattern, typically refer under the non-measured pattern of electric sphygmomanometer, the situation of middle valve of blinding off a line, perfect condition and each measurement pressure spot judge when pressure is static, but practical situation is also unsatisfactory.
The valve design of abandoning of electric sphygmomanometer has four kinds of patterns usually: (1) automatic air valve, mainly carries out the electric sphygmomanometer measured during blood pressure lowering; (2) pressure automatic control air valves and a mechanical vent valve are also mainly measure in pressure reduction; (3) two pressure automatic control air valves, one of them air valve is used for slow venting when measuring in pressure reduction; (4) only have a pressure automatic control air valve, be mainly applicable to the electric sphygmomanometer carrying out when boosting measuring.Above-mentioned the second is the most common with micro-vent valve, it measure static schema time often along with the slow venting of mechanical vent valve, real " static state " cannot be reached, then cannot finely tune air pressure for other three kinds, be difficult to control to accurately in industry standard required pressure point is measured again.Above problem inevitably easily causes following situation:
(1) cannot realize real static pressure measure and cause measured deviation, result erroneous judgement; (2) often blindly tearing machine measurement open causes model machine to damage; (3) inefficiency is measured.
Utility model content
This utility model in order to overcome the deficiency of above technology, provide a kind ofly realize measuring under real static pressure, measurement structure is accurately based on the static pressure accuracy test set of Pressure behaviour balance.
This utility model overcomes the technical scheme that its technical problem adopts:
Based on a static pressure accuracy test set for Pressure behaviour balance, comprising: inflator pump; The electric sphygmomanometer be connected with inflator pump by trachea, Pressure gauge and vent valve, the feeder ear of described inflator pump is connected to adjustable DC power supply.
In order to ensure pressure stability, also comprise air chamber, the inlet end of described air chamber utilizes trachea to be connected with electric sphygmomanometer with inflator pump by threeway, and the outlet side of described air chamber utilizes trachea to be connected with vent valve with Pressure gauge by threeway.
The beneficial effects of the utility model are: the voltage manually regulating adjustable DC power supply, it is made to raise gradually from initial pressure 0V, at this moment inflator pump also starts slow work, pipeline inner pressure slowly rises, Pressure gauge can show the inflation rate that force value controls inflator pump in real time, stop regulation voltage, pipeline inner pressure rises more and more slower, when inflator pump inflation rate and vent valve outgassing rate reach dynamic equilibrium, pipeline internal gas pressure is stablized, Pressure gauge can show force value in real time, thus the accuracy of the measurement of electric sphygmomanometer under can judging static pressure.

In figure, 1. Pressure gauge 2. vent valve 3. air chamber 4. inflator pump 5. adjustable DC power supply 6. electric sphygmomanometer.
Detailed description of the invention
Be described further below in conjunction with accompanying drawing 1 pair of this utility model.
Based on a static pressure accuracy test set for Pressure behaviour balance, comprising: inflator pump 4; The electric sphygmomanometer 6 be connected with inflator pump 4 by trachea, Pressure gauge 1 and vent valve 2, the feeder ear of inflator pump 4 is connected to adjustable DC power supply 5.Manually regulate the voltage of adjustable DC power supply 5, it is made to raise gradually from initial pressure 0V, at this moment inflator pump 4 also starts slow work, pipeline inner pressure slowly rises, Pressure gauge 1 can show the inflation rate that force value controls inflator pump 4 in real time, stop regulation voltage, pipeline inner pressure rises more and more slower, when inflator pump 4 inflation rate and vent valve 2 outgassing rate reach dynamic equilibrium, pipeline internal gas pressure is stablized, Pressure gauge 1 can show force value in real time, thus the accuracy of the measurement of electric sphygmomanometer 6 under can judging static pressure.
Further, can also comprise air chamber 3, the inlet end of air chamber 3 utilizes trachea to be connected with electric sphygmomanometer 6 with inflator pump 4 by threeway, and the outlet side of air chamber 3 utilizes trachea to be connected with vent valve 2 with Pressure gauge 1 by threeway.Air chamber 3 can play pressure maintaining effect, and when guaranteeing to measure, system pressure is stable, prevents system pressure from occurring excessive fluctuation and affecting the accuracy of measurement.
Concrete measuring method is as follows:
A) Pressure gauge 1, vent valve 2, air chamber 3, inflator pump 4 and adjustable DC power supply 5 is connected by the annexation in claim 1;
