Abstract
The invention discloses a sphygmomanometer and a dynamic sphygmomanometer using a 'vibration-korotkoff' combined slope method. According to the sphygmomanometer and the dynamic sphygmomanometer, invasive blood pressure is only used as a calibration reference, and artificial Kororkoff sound blood pressure does not need to be used for verifying any more. The sphygmomanometer is accurate, more suitable for the 'golden standard' of blood pressure, high in anti-interference capacity, convenient to use, capable of continuously and dynamically measuring the blood pressure and low in cost.

Description
Technical field
The invention discloses a kind of sphygomanometer, specifically one is only done reference-calibrating, is not needed with Ke Shi sound blood pressure, to carry out verification again with invasive blood pressure, adopts sphygomanometer and the dynamic hemomanometer of " shake-Ke " associating Slope Method.
Background technology
Real blood pressure should be the blood pressure of directly measuring in blood vessel, and this blood pressure claims " invasive blood pressure ".Invasive blood pressure is only describes real " goldstandard " of blood pressure state, but this blood pressure is because there being wound, forever cannot in the life except major operation, be applied.
For over 100 years more than a hundred years, in life, generally acknowledged blood pressure is the non-invasive blood pressure recording by Ke Shi sound method so far.
The whole world is demarcated the general method of electric sphygmomanometer accuracy and is had three: AAMI, IP and BHS.They all regulation with the non-invasive blood pressure of artificial Ke Shi sound interpretation, do standard, go to check the accuracy of existing electric sphygmomanometer.
The contrast of the blood pressure of measuring by existing artificial interpretation Ke Shi sound method and invasive blood pressure, systolic pressure the former lower than the latter (differing 0.8-13.4mmHg), diastolic pressure the former higher than the latter (differing 0.8-18mmHg).According to one's analysis, its reason is that Ke Shi sound measuring blood pressure exists approximately ten error factors such as " audition ", " vision ", " decompression opportunity ", " listening valve " error; Even also may comprise " toot threshold " (with Ke Shi sound do not disappear contrary, the constraint that the bright blood of pulse wave stave has broken through cuff, but blood vessel does not send Ke Shi sound.) error that causes.
The blood pressure recording with Ke Shi sound, known containing to have the Errors Catastrophic factor, the physical quantity of eliminating error factor (as " decompression opportunity " " toot threshold ") that wherein have or very difficult, this amount and show already and have respectively the phenomenon that is less than systolic pressure and be greater than diastolic pressure, regulation is done evaluation criterion by such physical quantity that comprises a lot of uncertain errors, not science.
Under this regulation, require electric sphygmomanometer to find out one and meet the blood pressure that contains a lot of error components, even accorded with completely, its blood pressure of measuring also can contain the error component identical with Ke Shi sound, is also false blood pressure; Because the various combination of the different error component of Ke Shi sound has infinite, with electric sphygmomanometer, automatically find out and meet Ke Shi sound completely to same blood pressure but error component difference, the various results that may measure are all coincide, both unreasonable, are also difficulties or even impossible.
Sasser is the reason that blood vessel sends Ke Shi sound, and Ke Shi sound is the existing picture that Sasser shows; But while seeking diastolic pressure, the holding of Sasser levies that a little to can not show a candle to Ke Shi sound obvious.
People early have recognized that and adopt dynamic hemomanometer follow-on test blood pressure could reflect real blood pressure situation.
The existing a exercise blood pressure meter with 3-D view technical finesse Ke Shi sound in market, accuracy should be fine, but price is wanted 50,000 yuan one.
Present dynamic electron sphygomanometer, all determines blood pressure by concussion method.Because of directly with pass by Ke Shi sound method measuring blood pressure time, except groups of people are not measured, and be very easily subject to the interference of various noises and more do not measure blood pressure.Therefore all in test arm band after the fluctuation of pressure, then use the statistic law calculating blood pressure in Sasser method.Its advantage is not to be subject to noise jamming, and each test can obtain one group of numerical value, but its value cannot prove the real pressure value of tested individuality.
There is the false failure rate of the dynamic hemomanometer of researcher requirement test use to be less than 20%.
Even if above-mentioned not accurate enough dynamic hemomanometer, more than ten thousand yuan, the approximately thousands of units to two of price; In hospital, test once also approximately needs 200 yuan.
Now without a dynamic electron sphygomanometer that is suitable for specially domestic,
