Abstract
The invention discloses a calibration method of an electronic sphygmomanometer and a calibrator. The calibrator is the electronic sphygmomanometer comprising an invasive blood pressure sensor, a kororkoff sound sensor, an air bag pressure sensor and an image displayer. Invasive blood pressure is taken as calibrating reference, only a pressure spectrum and a vibration spectrum or the pressure spectrum and a sound intensity spectrum stored in the calibrator are required to be input into the electronic sphygmomanometer to be tested, the most accurate accuracy of the sphygmomanometer can be obtained by comparing a displayed blood pressure value with an invasive blood pressure value, and the testing accuracy of the sphygmomanometer can be improved via revising and correcting the judgment of the blood pressure value. The calibrator totally meets the strictest concept of 'gold standard' of the sphygmomanometer, is convenient to use, and is a unique instrument capable of performing human body invasive blood pressure calibration for the electronic sphygmomanometer so far.
Description
Technical field
The present invention relates to a kind of demarcation sphygomanometer method of accuracy and device, specifically be a kind of can serve as to demarcate benchmark with the human body invasive blood pressure, detect standardizition and the calibration device of various non-invasive blood pressure measuring accuracy.
Background technology
The accuracy of sphygomanometer is very important sometimes.The data introduction is arranged, take certain depressor after the average blood pressure lowering difference of its 24h less than 2.5mmHg, this medicine is considered to invalid medicine.If the error of sphygomanometer is exactly the ten or eight millimetres of mercury easily, will makes treatment and judge that curative effect becomes very difficult.
For seeking no mercury pollution, test result easy to use sphygomanometer accurately again, people had both paid close attention to and had also done very big effort. and only domestic disclosed sphygomanometer patent just has more than 800 but does not see the above-mentioned sphygomanometer appearance that everybody admits so far as yet.
In helpless, people have to select the less product of error in reading in existing electric sphygmomanometer.And the standard of selecting in all hypertension tissues, is all stipulated the artificial reading of electric sphygmomanometer with the mercury gauge sphygmomanometer of measuring by " goldstandard " Ke Shi sound method compared.
Because there not being automatic mercury gauge sphygmomanometer, so can only be preferably clear-headed and clear-sighted have an experience person, take on mercury gauge sphygmomanometer reading operator.Show in the disclosed data that even the operator who optimizes, it is actual, and to read the dispersion of pressure value still very big, its maximum can surpass 15mmHg.
The situation of reality is, except can not supplying the electric sphygmomanometer more accurately of actual domestic, even can not eliminate man's activity, be worth directly with the human actual measurement compare, the human blood-pressure calibration device of detected electrons sphygomanometer accuracy.Because of no calibration device, various countries only make Static Detection to the actual standard verification regulation of sphygomanometer, namely only detect the accuracy of the pressure transducer of sphygomanometer.And when measuring blood pressure, largest error source is not the error that produces in the test of pressure, represents blood pressure but how to choose pressure values when.
After measuring pressure value with image method, existing people's proposition goes to judge electric sphygmomanometer method of accuracy patent " 200810084589.2 ", but fail in this patent to propose how to determine its Ke Shi sound originating point and end point at various atypia Ke Shi sounds, so need the problem that solves in method and the unresolved non-image method.
Summary of the invention
The objective of the invention is to find a kind of the simplest, exempt man's activity in the test process, scaling method and the calibration device of detected electrons sphygomanometer accuracy fully.
The present invention adopts the human body invasive blood pressure that electric sphygmomanometer is demarcated.
This sphygomanometer calibration device is an electric sphygmomanometer that increases invasive blood pressure sensor, for example comprises the electric sphygmomanometer of invasive blood pressure sensor, korotkoff sound sensor, bladder pressure sensor and image display
This standardizition earlier with calibration device gather simultaneously human body invasive blood pressure, contain air pressure spectrum and the Ke Shi sound sound intensity peak value spectrum of the air bag of Sasser; Afterwards, carry out the oneself of sphygomanometer or demarcation mutually again.
Sphygomanometer oneself timing signal, with record in the marking apparatus bladder pressure spectrum and concussion spectrum or pressure spectrum and sound intensity spectrum signal signal, in the air bag gas pressure curve, by corresponding to the systolic pressure in the invasive blood pressure and diastolic pressure time of occurrence, anti-" Ke Shi sound " right originating point and the end point in sound intensity spectrum of releasing, can set up accordingly and how seek the criterion of originating point and end point in the different Ke Shi sound images or carry out image recognition, improve the accuracy of sphygomanometer.
Mutual timing signal between the sphygomanometer, with record in the marking apparatus bladder pressure spectrum and concussion spectrum or pressure spectrum and sound intensity spectrum signal signal, flow to electric sphygmomanometer to be calibrated, again by the oscillographic method calculation procedure in the sphygomanometer or Ke Shi sound option program, analyze pressure spectrum and concussion spectrum or pressure spectrum and Ke Shi music in the signal, obtain or find out pressure value, at last with the invasive blood pressure value contrast of its value with corresponding actual measurement, the i.e. accuracy of the oscillographic method of being demarcated as can be known or Ke Shi sound method electric sphygmomanometer.
Invasive blood pressure can be by calibration device in operation process, obtains from the signal of telecommunication of the invasive blood pressure sensor of parallel connection; Also can be by directly reading in the invasive blood pressure monitor in the operation process.
Advantage of the present invention.
1, adopts the human body invasive blood pressure to do the blood pressure benchmark of calibration device, near human body actual blood pressure situation, meet the strictest requirement of measuring blood pressure " goldstandard "; Utilize in the process of performing the operation and obtain invasive blood pressure, can the simple and genuine unrestricted actual measurement basic data of quantity that obtains of people.
2, this calibration device can be determined Ke Shi sound originating point and end point intuitively in image display; The invasive blood pressure that also can utilize actual measurement to arrive, anti-right originating point and the end point of pushing away in corresponding atypia Ke Shi sound collection of illustrative plates; Accordingly, can seek the relation between invasive blood pressure, originating point and end point and the collection of illustrative plates, Posing helps and is based upon the criterion of seeking originating point and end point in the various Ke Shi sound collection of illustrative plates, goes back the usable image recognition technology, seeks the pressure value of various atypia Ke Shi sound collection of illustrative plates correspondences automatically.
3, this calibration device use simple, be unique so far can be the instrument that object is done non-static demarcating with the human body invasive blood pressure to sphygomanometer
Standardizition of the present invention and calibration device, except can demarcating its exactness of standard of electric sphygmomanometer, also can utilize the rule in the graph of a relation of invasive blood pressure-Sasser in the calibration device-Ke third constellations sound sound intensity spectrum, seek and how to determine atypia Ke Shi sound person's originating point and the criterion of end point, or directly with artificial or automated graphics recognition technology contrast, infer its right pressure value after finding similar graph of a relation.
