Description

A kind of blood pressure measuring method
Technical field
The present invention relates to a kind of blood pressure measuring method, can use at automatic sphygmomanometer, monitor and other to relate in the instrument that human blood-pressure measures, belong to the blood pressure measurement technical field.
Background technology
The method of no-invasive measurement of blood pressure mainly contains at present:
1. auscultation-Ke Shi sound the method that changes based on the blood vessel wall vibration melodies;
2. based on multispectral ultrasonic method of reining in ultrasonic principle;
3. based on the succusion (oscillographic method) of pulse pressure vibration.
Present widely used method will be calculated Ke Shi sound method, secondly is the succusion of using in recent years.The advantage that non-invasive blood pressure is measured is a no pain, measures simple and convenient.But also there are a lot of shortcomings:
1. measurement result is inaccurate.
2. can only measure arterial pressure.
3. in particular cases can not use at some, can only be used in routine examination.
Summary of the invention
The purpose of this invention is to provide a kind of high accuracy, can measure systolic pressure, diastolic pressure and mean pressure simultaneously, and widely used blood pressure measuring method.
In order to achieve the above object, technical scheme of the present invention provides a kind of blood pressure measuring method, it is characterized in that, concrete steps are:
The first step: oversleeve is inflated automatically, and each inflation makes pressure increase 10-40mmHg, detects the maximum of identification pulse wave, and the pressure of this moment is mean pressure; Continue inflation and detect pulse, when pulse intensity is that pulse wave is peaked 50% the time, the pressure of this moment is systolic pressure; Finish inflation and measure for the first time, calculate diastolic pressure according to the waveform figure that measures, wherein, the value of diastolic pressure be pressure less than mean pressure, and pulse intensity is the pressure at 60% place of maximum pulse intensity;
Second step: carry out the inflation and measure second time, be inflated to atmospheric pressure value than the high 10-20mmHg of systolic pressure, progressively the pulse wave detection is carried out in venting afterwards, each venting makes pressure reduce 3-5mmHg, in deflation course, make with light pulse detection equipment and sound pulse detection equipment correction systolic pressure, when optical signal was arrived in the Equipment Inspection of light pulse detection and the while, acoustical signal was arrived in the Equipment Inspection of sound pulse detection, the pressure of this moment was revised systolic pressure.
Principle of the present invention is:
(1) judgement of mean pressure: mean pressure is the integral mean of systolic pressure and diastolic pressure, the trend that its reaction systolic pressure and diastolic pressure change.According to present medical knowledge, when pulse wave was the strongest, corresponding oversleeve force value and human body mean pressure were quite approaching.Therefore, will vibrate the corresponding oversleeve force value of the amplitude peak point of pulse wave in the present invention as mean pressure.
(2) judgement of diastolic pressure: the method that the present invention uses is, the diastolic pressure the most of the pairing force value of 60% maximum pulse intensity in the trailing edge that vibrates.
(3) judgement of systolic pressure: systolic pressure reaction be the oversleeve pressure of blood vessel when just having opened, detected pulse wave amplitude is very little, be difficult to accurately determine, so the present invention uses the bonded method of several different methods to judge.The present invention mainly uses two kinds of methods in conjunction with judgement.Wherein a kind of method is pairing force value during 50% amplitude peak in the pulse wave rising edge, and another kind of method is to use auxiliary facilities, and two kinds of analytical calculations that method combines can improve certainty of measurement.Will use auxiliary facilities to detect pulse simultaneously in measuring process, auxiliary facilities places the side of oversleeve away from heart.Since blood flow be flow to from heart acral, so when oversleeve pressure blocking-up blood vessel, just detect in the auxiliary facilities less than pulse, in auxiliary facilities, detect pulse, illustrate that blood vessel opens, the oversleeve pressure of this moment can be thought systolic pressure, and the systolic pressure comparative analysis of obtaining according to these two methods draws reliable systolic pressure value.
(4) described auxiliary facilities has two kinds, i.e. light pulse detection equipment and sound pulse detection equipment.
(5) described smooth pulse wave checkout equipment uses blood of human body to have the principle of bigger trap to detect pulse wave to infrared light.Equipment receives two parts with infrared light emission and infrared signal to be formed, and the infrared light transmitting terminal uses the infrared light diode, and wavelength of light emitted is 920nm.Infrared diode is in luminance with the electric current of 10mA always.The infrared light receiving terminal uses the infrared light audion, and its conducting electric current is according to the Strength Changes of the infrared light that receives, and the conducting electric current that system detects infrared audion just can detect current infrared light intensity.Transmitting terminal and receiving terminal are packed in (fingerstall figure) in the fingerstall, lay respectively at the both sides of fingerstall.Light pulse detection equipment is sandwiched in the end of extremity, just on finger and the toe.During measurement, finger or toe are put into fingerstall, finger just separates transmitting and receiving end, and infrared transmission is crossed the finger back to infrared audion.Because the blood of finger in the tremulous pulse is different in pulse cycle, also just different to the absorption of infrared light, the signal that so infrared audion receives changes along with pulse, so interimly in pulse can detect pulse wave.
(6) described pulse sound detection checkout equipment is positioned over below the oversleeve.Equipment uses pick up, is similar to mike, can detect acoustical signal.Because blood flow has slight sound when crossing blood vessel, so can be positioned over checkout equipment near arterial vascular place, acoustical signal is carried out amplification detection, detect pulse wave.In pulse cycle,,, so just can detect pulse wave so intensity of sound also is different owing to the blood that flows through blood vessel is different.
Advantage of the present invention is, auscultation and succusion are attached in the electronic measurement technique, makes accuracy and the concordance measured effectively improve.
Description of drawings
Fig. 1 is the sketch map of pressure and waveform.
The specific embodiment
As shown in Figure 1, be the sketch map of pressure and waveform, wherein, the P coordinate shows the size of force value, and the T coordinate is the time, and the curve among the figure is the pulse wave waveform and is meant pulse wave size under the different pressures situation.When the pressure in the oversleeve during greater than systolic pressure, blood vessel is blocked, and detects less than pulse wave in the oversleeve.When pressure descends, near systolic pressure, because arteries is opened, waveform is that the peak value of pulse wave intensity begins to increase, and the pressure of this point is systolic pressure SP.Along with oversleeve pressure descends, blood vessel is further opened, and pulse wave intensity continues to increase, and the oversleeve pressure when reaching peak-peak is thought mean pressure MP clinically.Pressure continues to descend afterwards, and oversleeve is to the blocking-up complete opening of tremulous pulse, and the wave of oscillation reduces the effect of oversleeve, and detected pulse wave also reduces.Until detected pulse wave minimum, diastolic pressure DP is present in the middle of this minimum pulse wave.The invention will be further described below in conjunction with embodiment.
