Description
Technical field
The present invention relates to a kind of blood pressure measurement devices and its operating method for having arm-rest belt.
Background technique
Generally using the blood pressure of electronic sphygmomanometer (electronic sphygmomanometer) measurement artery, will include
There is blood pressure determination arm-rest belt (cuff) to wind and be fixed on upper arm or wrist, and arm-rest belt is pressurizeed and depressurized.Work as pressure
Arteries and veins band is inflated and pressurizes and deflate to depressurize, and the volume of the blood vessel to suffer oppression can generate variation, thus changed by arm-rest belt
Amplitude variations are referred to as oscillography oscillation (oscillometric) method to calculate the technology of blood pressure.
As described above, in the electronic sphygmomanometer using oscillography succusion, when the arm-rest belt for being fixed on upper arm or wrist
When pressure changes, the amplitude for causing arm-rest belt to change because of the variation of the volume of blood vessel can also change.Even identical pressure
The arm-rest belt of power, when the volume of blood vessel changes, the amplitude that arm-rest belt changes may also can change.
If the winding strength (linking tape) to fixed arm-rest belt is insufficient, blood is not oppressed really in arm-rest belt pressurization
Pipe can not effectively reach the predetermined degree for pressing off blood flow in blood vessel, so that the accuracy in measurement of blood pressure is bad.Even exist
The improper variation of the state that if arm-rest belt is wound in pressurization (such as: linking tape joint surface is relative to loosening or movement), so pressurization
When the blood pressure measuring to be carried out can be quite inaccurate.Therefore, it after the detected part that arm-rest belt is wound in body, needs really
It is fixed in fact and suitably, can correctly obtain the numerical value of blood pressure measuring whereby.
The confirmation of conditional electronic sphygmomanometer be wound in detected part arm-rest belt whether tension, appropriate or too loose, be mostly to add
Judged in pressure by the pressure variety in detection arm-rest belt.Fig. 1 shows that the pressure change in arm-rest belt winds degree with it
Between relativeness schematic diagram.Straight line A is that indicate that arm-rest belt is wound in detected part too tight, therefore is detected in pressurization in figure
It is larger that pressure in arm-rest belt changes over time slope.Such as: when the slope be more than upper threshold value, then can determine whether arm-rest belt
Winding degree tension.Compared to straight line A, straight line C is that indicate that arm-rest belt is wound in detected part excessively loose, therefore in pressurization Shi Suojian
Measuring the pressure in arm-rest belt, to change over time slope smaller.Such as: when the slope be less than lower threshold value, then can determine whether arm-rest belt
Winding degree it is too loose.When arm-rest belt is suitably wound in detected part, as in figure straight line B present the pressure in arm-rest belt with
Time change slope is preferable.
Though the method for the winding degree of above-mentioned tradition confirmation arm-rest belt can exclude certain too loose or too tight improper to use shape
Condition so only still has shortcoming by the pressure in detection arm-rest belt.Such as: when arm-rest belt is wound in hand axle portion or wrist joint
Place, or the stylolitic part of furniture is even wound in as toy by child, even if be wound will not be too loose or too tight for arm-rest belt,
But its internal pressure changes over time slope and is possible to fall in acceptable range.It is, tradition confirmation arm-rest belt
The method and non-optimal of winding degree, it would still be possible to can not correctly obtain the numerical value of blood pressure measuring.
Aiming at the problem that the above-mentioned prior art is met with, the present invention proposes a kind of method for operating blood pressure measurement device, and

θ more can determine that the height of the blood pressure measurement device 50 is correct, and the correctness so measured to pressure value just can ensure that.
It is described in detail, blood pressure measurement device 50 is the blood pressure for measuring wrist artery, and it includes body part 51 and pressure arteries and veins
Band 52.The internal circuit framework of the body part 51 and surface setting component can be found in the narration of preceding embodiment.When the use blood
Press measuring equipment 50 measure blood pressure when, it is proposed that the wrist for winding the blood pressure measurement device 50 is lifted, and make its height about with the heart
Same or similar dirty 82 height is best, therefore can obtain accurate pressure value.In addition to confirming the pressure using the above method
Arteries and veins band 52 is suitably wound, it is also desirable to which the body part 51 is placed in heart 82 with high position, is so measured and is arrived pressure value
Correctness just can ensure that.The present embodiment uses acceleration transducer (gravity sensor or G sensor) 514, can sense
The tiltangleθ of the body part 51 can calculate and convert the height of the blood pressure measurement device 50 by the tiltangleθ, so can be true
Recognize whether with heart 82 with high, so as to correctly measure the numerical value of blood pressure.It illustrates herein, when user's misoperation,
Such as lifted head or lowerd arm and cross waist etc., cause blood pressure measurement device 50 not with 82 position of heart with it is high when, at this time
Height and signal strength it is all incorrect, blood pressure measurement device 50 show immediately mistake warning or force stop measure blood pressure.
Technology contents and technical characterstic of the invention have revealed that as above, however those skilled in the art are still potentially based on
Enlightenment and announcement of the invention and make various replacements and modification without departing substantially from spirit of that invention.Therefore, protection scope of the present invention
It should be not limited to the revealed content of embodiment, and should include various without departing substantially from replacement and modification of the invention, and with claim
