Description
Technical field
The present invention is to be related to Medical Devices detection technique field, specifically a kind of dynamic blood for measuring electronic sphygmomanometer
Press simulator.
Background technique
Blood pressure measurement is divided into invasive blood pressure measurement and non-invasive blood pressure measurement.Invasive blood pressure measurement is suitable for all kinds of critical illnesses
Big blood loss in the possible art such as open heart operations, big vascular surgery, organ transplantation under people, circulatory insufficiency, extracorporal circulatory system
Operation；Severe hypotension, shock, other blood flow flowing instability diseases or non-invasive blood pressure are difficult to human observer.Carry out invasive blood
Pressure measurement need to be inserted into conduit or monitoring probe through body surface and directly measure to the chambers of the heart or Endovascular.With clinical common non-invasive blood pressure
Monitoring is compared, and invasive blood pressure can provide continuous, reliable and accurate monitoring data, but need when invasive blood pressure measurement practical operation
Instrument and the operation medical worker of profession are wanted, measurement process is complicated, be not suitable for daily blood pressure measurement, therefore the monitoring of daily blood pressure
It is non-invasive blood pressure measurement, opens the blood flow that the moment occurs using arteries and veins overpressure and blood blocking and change system, surveyed from body surface
Corresponding pressure value out, i.e., blood blocks the pulse situation of change for opening moment occlusive gas sleeve distal side in detection vascular, in body
The outer method that blood pressure is measured using various conversion methods and signal processing technology.
Sphygmomanometer is the instrument of no-invasive measurement of blood pressure, and sphygmomanometer mainly has stethoscopy sphygmomanometer and oscillographic method sphygmomanometer.
Stethoscopy (being called artificial Korotkoff's Sound method) sphygmomanometer mainly has: mercurial sphygmomanometer (pressure gauge), spring gauge type blood pressure
Meter, press polish column sphygmomanometer, light show sphygmomanometer, liquid crystal sphygmomanometer etc..For this method by cuff aerating, blood vessel of extruding keeps blood flow complete
It is complete stifled disconnected, it at this moment can't hear the fluctuation sound of blood vessel with stethoscope, then slowly deflate until hearing pulse sound, blood pressure is height at this time
Pressure, i.e. systolic pressure.Continue to deflate, powerful pulse sound can be heard by stethoscope, waits a moment and lightens slowly, until hearing very flat
Surely compared with normal pulse sound, think that blood vessel is not squeezed completely at this time, blood pressure is low pressure, i.e. diastolic pressure.
Oscillographic method is called succusion, its principle is to obtain the oscillation wave generated in deflation course, passes through certain calculation
Method conversion obtains pressure value, measures indirectly, most of electronic sphygmomanometer is designed using oscillography principle.Show
Wave method is a kind of more advanced electronic measuring method to grow up the nineties, and the principle is as follows: cuff being bundled in hand first
On arm, automatically to cuff inflation, start to deflate to certain pressure；When air pressure drop to a certain extent, blood flow can by blood vessel, and
There is certain oscillation wave；Oscillation wave travels to the pressure sensor in machine by tracheae；Pressure sensor energy real-time detection arrives
Pressure and fluctuation in surveyed cuff；It gradually deflates, oscillation wave is increasing；Continue to deflate, at this time due to cuff and arm
Contact fluffs, therefore pressure sensor pressure detected and fluctuation are smaller and smaller.Oscillographic method is not vulnerable to measured's pulse signal
Strong and weak influence, reproducible, accuracy is higher, but interferes vulnerable to extraneous vibration, and when low pressure measurement is gentle vulnerable to deflation speed
The rigidity of pipe influences.
The appearance of electronic sphygmomanometer and universal, enters family by hospital for sphygmomanometer and creates advantage.Due to the person
After the reason of body causes blood pressure in the exception of different time, for example sleep is got up, after meal, postexercise blood pressure is different.At this moment
Just more seem the important of Home blood pressure meter, and people can often measure the blood pressure of oneself, measure in different times, can also be with every
Its fixed several period goes to measure, and finds the rule of oneself blood pressure, these data to doctor, preferably controls and treat high blood
Pressure.
The accuracy of blood pressure variable ensures sphygmomanometer use reliability, it is ensured that resident living safety, while as medical treatment
Equipment is also required to periodically be detected, it is ensured that the reliability of transmission of quantity value.
Currently, the measurement technology mechanism in China carries out different types of sphygmomanometer since the type of sphygmomanometer is different
The method and apparatus of detection is different: mercurial sphygmomanometer inputs static pressure to sphygmomanometer by static pressure source, measure (0~
300) static pressure in mmHg；Two parts: static pressure part are largely divided into for electronic sphygmomanometer blood pressure detecting part
And dynamic pressure part, wherein static pressure part is still to be measured by way of static pressure source；Dynamic pressure portion
Point, domestic corresponding standard not yet generally uses Noninvasive blood pressure simulator (or non-invasive blood pressure analyzer).
Existing Noninvasive blood pressure simulator is all to reappear method using blood pressure envelope to work in the market, can be according to flat
Press the systolic pressure and diastolic pressure that pressure value is determined with corresponding proportionality coefficient.But the non-invasive blood pressure mould of different manufacturer's productions
The proportionality coefficient of quasi- device is different, and the variation tendency of the blood pressure pulse wave of the simulated generation of every kind of Noninvasive blood pressure simulator
Also not exactly the same.Based on the above situation, if evaluating the accurate of non-invasive blood pressure measurement using this Noninvasive blood pressure simulator
Property the production of different manufacturers will occur blood pressure measuring take blood pressure inaccurate problem, and use the noninvasive blood of different manufacturers production
Press simulator that can also obtain different testing results to detect the blood pressure measurement performance of the same sphygmomanometer.Although it can be seen that
Existing Noninvasive blood pressure simulator can be used as the instrument of detection non-invasive blood pressure measurement reproducibility, but also be not belonging to completely standardize
Detection device, for no other reason than that it is available more to standardize more reasonable detection device without other at present.According to this non-invasive blood pressure
The testing principle of simulator, it can be found that having following defects that (1) concept is unintelligible.This blood pressure simulator is not with blood pressure
Based on the physical concept of value, but from the measurement process of electronic sphygmomanometer, the measurement pilot process of electronic sphygmomanometer
Electron sphygmomanometer is restored, i.e., given by it is not a physical quantity but a process, therefore it is fuzzy that it, which measures concept,
's；It (2) can not magnitude tracing.Since the course of work of this blood pressure simulator is one measurement process of reduction, the value that it is exported
The only nominal value of a statistical induction, rather than standard value.Therefore, these nominal values are can not to calculate its accuracy, this
Detection device is actually that envelope is played back to electronic sphygmomanometer, and the nominal pressure value of the envelope that it is played back cannot pass through
The method of experiment finds out or verifies its uncertainty, so this device cannot achieve magnitude tracing；It (3) can not be fully to electricity
Sub- sphygmomanometer is calibrated.This blood pressure simulator passes through pipeline when in use and is directly connected to electronic sphygmomanometer, built-in cuff
Or cuff is intended only as gas appearance, auxiliary automatic exhaust steam valve controls exhaust velocity.And when electronic sphygmomanometer measurement human blood-pressure, cuff
It is a part of sense of participation as sensor by small-pulse effect, it is improper that the transmittability of cuff, which is foreclosed, in calibration
's.
It can be seen that although these existing blood pressure simulators can be used for noninvasive automatic measuring sphygmomanometer repeatability at present
Detection, but its detection technique is there are certain defect, can not really complete entire sphygmomanometer system (including cuff) can
The standard blood wave indicating value repeatability of magnitude tracing detects.Therefore develop it is a can to electronic sphygmomanometer carry out dynamic pressure amount
The ambulatory blood pressure simulator that value is traced to the source is a problem to be solved, can real simulation human body ambulatory blood pressure, solve different measurements
The unification of the electronic sphygmomanometer detection method of method, and the detection method of electronic sphygmomanometer is revised, to electronic sphygmomanometer
Magnitude measured comprehensively.
