Abstract
The invention relates to a medical instrument for measuring the blood pressure and a blood-pressure measuring method. The blood-pressure measuring instrument consists of a pressure measuring part and an auscultation part, wherein the pressure measuring part adopts a pressure gauge, and an electric sensing element also can be adopted to convert the pressure value to a visible number. The pressure measuring part is vertically (or horizontally) overlapped with the auscultation part into a whole. A gold standard-Korotkoff-Sound auscultatory method for measuring the blood pressure is adopted by the instrument. When the blood-pressure measuring instrument is used for measuring the blood pressure, the blood-pressure measuring instrument is arranged on brachial artery of the human body to be leveled to the heart, pressure is applied by direct pressing (rather than by inflation of a sleeve band), so the instrument squeezes the brachial artery to completely stop the blood stream, then the pressure is slowly decreased until the auscultation part can hear the pulse sound, and the current measuring value of the pressure measuring part is the highest value (systolic pressure) of the blood pressure; and the pressure is continued to decrease slowly until the pulse sound completely disappeares, and the current measuring value of the measuring part is the lowest value (diastolic pressure) of the blood pressure. The instrument and the measuring method are free from the mercury pollution and are free from the assistance of the sleeve band, so the measuring instrument is convenient to carry, is simple and quick to operate and is accurate to measure the blood pressure.
Description
Technical field
The present invention relates to a kind of Medical Instruments and method of measuring blood pressure, this instrument does not have hydrargyrum, no cuff, and this method can be measured blood pressure more fast and accurately.
Background technology
1905, Soviet Union doctor Korotkoff found the Ke Shi sound, had established Ke Shi sound auscultation blood pressure measurement technology, made it become " goldstandard " of blood pressure measurement clinically
[1], this method is made up of sphygomanometer, cuff and stethoscope, and non-invasive blood pressure is measured and is widely accepted clinically and uses so far.At present, known Ke Shi sound auscultation blood pressure is in respect of hydrargyrum (mercury column) sphygomanometer, air pressure meter type blood pressure meter, and both are also general in Clinical Application at present.Wherein mercurial sphygmomanometer carries out " goldstandard " that the non-invasive blood pressure measurement is considered to indirect sphygmomanometry to the people
[2,3], but hydrargyrum belongs to a heavy metal species, and the health of social environment and human body is brought many negative effects.From on July 1st, 2006, the electronic electric equipment that contains hydrargyrum was prohibited from entering the European Union consumption market; The Japan and the U.S. also begin the mercury clinical thermometer that prohibits selling from a plurality of states in 2000 and city, and China began to carry out the electronic and electrical equipment that contains hydrargyrum is implemented the restriction access in 2007, so the use of mercurial sphygmomanometer will receive further restriction
[4]Hill in 1697 and Bernard use the mechanical system recording blood pressure of metal first; And develop into the air pressure meter type blood pressure meter of present widespread usage; This sphygomanometer is light, carry easily; Less generation mechanical damage; Than movably equipment is more accurate; And the negative effect of not having hydrargyrum, thus comparatively general in Clinical Application, and have development potentiality preferably.And the electric sphygmomanometer that is rising at present generally adopts oscillographic method to measure blood pressure; Shortcoming is that measurement data is discrete; Be not suitable for obesity, arrhythmia, severe dyspnea and hypothermia patient and be connected heart-lung machine, Parkinson's disease patient; So the development prospect of oscillographic method electric sphygmomanometer still needs further fastidious, and it still needs auxiliary completion of cuff to measure.In a word, mercurial sphygmomanometer and the common technical characterstic of air pressure meter type blood pressure meter are all to use Ke Shi sound auscultation to measure blood pressure, all need cuff auxiliary together with electric sphygmomanometer.And cuff is assisted and in clinical practice, had great inconvenience, and shortcoming is following: 1. increased the step of blood pressure measurement operation, made the blood pressure complex operation step, cuff is auxiliary when especially the patient being rescued has wasted a large amount of quality time; The elasticity of cuff ratio, cuff shape, cuff position, cuff and inflation, venting speed all affect to the actual blood pressure value when 2. measuring, and make data owe reliable
[5]Therefore, seek new blood pressure measuring instrument and measuring method and become present urgent problem.
Summary of the invention
In order to overcome in the present mercurial sphygmomanometer hydrargyrum to the negative effect of environment and human body; And mercurial sphygmomanometer, air pressure meter type blood pressure meter and electric sphygmomanometer all need deficiencies such as cuff subsidiary; The present invention provides a kind of blood pressure measuring instrument that does not have hydrargyrum, no cuff; This instrument is when avoiding mercury pollution; Do not need the auxiliary of cuff; Realize the blocking-up of brachial artery blood flow and logical again through the direct change dynamics of " pushing ", can measure human blood-pressure more accurately and rapidly.
The technical scheme that technical solution problem of the present invention is adopted is: this instrument directly is made up of pressure measurement unit and auscultation parts, and it is auxiliary to need not cuff.Pressure measurement unit can adopt Pressure gauge, and its operation principle is with the air gauge in the air pressure meter type blood pressure meter; Also can adopt the electronic induction original paper to make force value be transformed into viewable numbers.The demonstration of blood pressure measurement can be adopted pointer dial type or electronics viewable numbers display.Pressure measurement unit places (or preceding), and the auscultation parts place down (or back), and both are connected as a single entity at overlapping (or front and back).This instrument still adopts " goldstandard "----Ke Shi sound auscultation on the blood pressure measurement to carry out blood pressure measurement, and wherein in the Instrument assembly: pressure measurement unit can be measured the human body artery blood pressure indirectly, and the auscultation parts then can be used for listening the Ke Shi sound of tremulous pulse.Method and the principle measured: during measurement instrument placed human body brachial artery heart level place; Directly exert pressure through " pushing " (but not the cuff inflation is exerted pressure); Make instrument extruding brachial artery blood vessel; Make blood flow stifled fully disconnected; Auscultation this moment parts can't be heard pulse sound; Slowly be decompressed to then and hear pulse sound, be the peak (systolic pressure) of blood pressure this moment; Continue slowly decompression, can hear through the auscultation parts that powerful pulse sound is waited a moment and weaken slowly that until the sound complete obiteration of beating, can think that blood vessel is not squeezed fully this moment, this moment, the reading of pressure measuring instrument was blood pressure minimum (diastolic pressure)
[6]This method also is present international Ke Shi sound auscultation.This method is the interaction principle according to power, " pressure that blood vessel receives "=" applied pressure "+" gravity of survey meter of blood pressure ", and through further standard blood pressure correction and unit conversion, thereby draw tested human blood-pressure value.This blood pressure measuring instrument measuring process only needs 5-7 second, and the auxiliary sphygomanometer of cuff that needs that Measuring Time is more traditional obviously shortens.
The invention has the beneficial effects as follows that this instrument does not have hydrargyrum, and to pollute, need not cuff auxiliary, easy to carry, simple to operate, quick, measures accurately.
