Description
Technical field
The present invention relates to blood pressure test device and using its blood pressure test method, more body, be related to it is a kind of by pair
Blood vessel pressurize and test reaction pressure, thus carries out blood pressure test, and mended by the coefficient of elasticity of skin and blood vessel
Just, so as to measuring accurate blood pressure and can realize the blood pressure test device of continuously blood pressure tracking and utilize its continuous blood
Press test method.
Background technique
In general, device of the blood pressure test device including the use of invasive method and the device using noninvasive method.
As the invasive method, representative example be will be used to test vascular pressure conduit insertion peripheral arterial simultaneously
Directly test vascular pressure method, this method have arterial hamorrhage danger, as test health status device due to
It needs to carry out in intrusive body, has the shortcomings that be unsuitable for frequently and be convenient to use.
In addition, representative example is using the method using mercurial sphygmomanometer as the noninvasive method.It is this
Using the method for mercurial sphygmomanometer by utilizing stethoscope while being exhausted at leisure after test position applies pressure
Or feel surveys pulse, would know that blood with the height of the mercury shown on extinction time point by putting at the beginning of arteries and veins
Pressure.
The blood pressure test device using noninvasive method mainly utilizes oscillography used as electronic type method of testing
(Oscillometric) blood pressure test device of method.Oscillographic method, which refers to, winds sphygmomanometer on upper wrist or lower wrist or wrist
Cuff (cuff) and inject air and make its expand after, sense and remember again by pressure sensor (pressure sensor)
The size of the pressure oscillation (pressure oscillation) generated on sphygmomanometer girding when air is discharged is recorded, and tests blood
The method of pressure.
That is, using oscillography (Oscillometric) method blood pressure test device include can wind upper wrist or lower wrist or
Wrist and the sphygmomanometer girding that can internally inject air, and for sensing the pressure oscillation generated in the sphygmomanometer girding
The pressure sensor of the size of (pressure oscillation).
It is described to be passed through using the blood pressure test device of oscillography (Oscillometric) method in upper wrist or lower wrist or wrist
Upper winding sphygmomanometer girding simultaneously tests blood pressure, has the advantages that be easy test, but due to transmitting media using air as pressure,
Distorted signals can be generated.
In addition, ensuring sphygmomanometer girding consciously using the blood pressure test device of oscillography (Oscillometric) method
Can simplify the explanation of signal when the linear variation of interior air pressure, but even if air injection rate hourly be it is a certain amount of, by
The residual volume of air and the reaction of pressure that are then based in air chamber (Air Chamber) and inject the system with gas leakage, it is empty
The pressure of air cavity (Air Chamber) is difficult to linear increase or reduction, accordingly, it is difficult to carry out to the reaction of blood vessel linear
It adjusts.
Therefore, using the blood pressure test device of oscillography (Oscillometric) method due to there are the distorted signals and by
In being difficult the problem of reaction to blood vessel carries out linear regulation, therefore compared to the blood pressure test device based on invasive method,
There is a problem of that accuracy is low when testing blood pressure.
In addition, using the blood pressure test device of oscillography (Oscillometric) method due to by being infused into sphygmomanometer girding
Entering air expands sphygmomanometer girding, and shrinks and need the time, therefore there are problems that continuously testing blood pressure.
In addition, needing the case where confirming blood pressure periodically for the state according to patient, oscillography is utilized
It (Oscillometric) can be right when sphygmomanometer girding is wrapped on upper wrist or wrist and tests blood pressure by the blood pressure test device of method
Part presses with all strength.When carrying out blood pressure test to the patient in sleep, existing instead due to can harm the sleep of patient makes to suffer from
The problem of health of person more deteriorates.
In addition, recently, develop a kind of device, the shortcomings which improve non-invasive blood pressure test devices, using non-
Blood pressure can be continuously tested while invasive method.
For this device, due to electrocardiogram (electrocardiogram, ECG) and photoplethysmography
(photoplethysmography, PPG) instrument can test blood pressure, but due to needing two kinds of devices, and need to body
Each position carry out blood pressure test, therefore cumbersome, user may feel inconvenient.Moreover, the standard of the blood pressure of measurement
Exactness compared to blood pressure itself accuracy and the shortcomings that rely more on two kinds of equipment used in the method.
