Description
Technical field
The present invention relates to a kind of blood pressure measuring device and blood pressure measuring method.
Background technology
Blood pressure measurement is hospital carries out medical inspection to human body a project commonly used, blood pressure measuring device is one of indispensable armarium of hospital, and along with the raising of social life level, people's health perception is strengthened thereupon, many families also all have blood pressure measuring device, so that at any time kinsfolk's blood pressure measurement is monitored kinsfolk's health status.
Blood pressure measuring device of the prior art comprises non-electronic blood pressure measurement device and electronic blood pressure measurement device, what wherein adopt non-electronic surveying blood pressure device is to adopt Ke Shi sound method, adopt many employings vibration oscillographic methods of electronic blood pressure measurement device, the Ke Shi sound method that adopts is also arranged.
1, Ke Shi sound method: be as vascular blocking device with a cuff, the air bag that has the band trachea in the cuff, when measuring blood pressure cuff is bonded on the arm, one is used to survey the stethoscope of blood vessel pulse, be placed on the below of cuff armrest one side, again by trachea to airbag aeration, make the systolic pressure of the interior air pressure of air bag greater than heart, this moment the cuff blocking blood flow, cuff armrest no blood on one side passes through, stethoscope also be can't hear any pulse sound, and then slowly venting of beginning, when the air pressure in the air bag was equal to or less than systolic pressure, stethoscope began to hear pulse sound, and the gas pressure in the pairing air bag of first pulse sound is designated as systolic pressure; Cuff continues venting, and when the pulse sound modified tone or noiseless suddenly that stethoscope is heard, the gas pressure in the air bag is designated as diastolic pressure at this moment.
Ke Shi sound method is measured blood pressure and had following shortcoming: no matter measure blood pressure in this way, be that the employing electronic surveying also is non-electronic measuring device, all needs a pick up.During measurement, this device must be aimed at pulse, if do not aim at, a kind of situation is not detect blood pressure, reapposes pick up.Another kind of situation, pick up is placed with and departs from, and when pulse signal, can not in time hear pulse sound, can cause the measurement error erroneous judgement this moment.In addition, be not suitable for the blood pressure of measuring child.Because child's blood vessels are more tiny, stethoscope almost can't detect child's blood vessel pulse, therefore can't measure child's blood pressure.
2, vibration oscillographic method: this method is used for the electronic blood pressure measurement device more, and its blood pressure measurement is to cause that by pulse the feature of the envelope of cuff internal gas pressure Oscillation Amplitude and amplitude thereof obtains by judging.Its determination methods is divided into two classes substantially, finds the mathematical model of an envelope by experiment.Establish characteristic point according to model.Such as the percentage ratio method, behind the envelope normalizing that had both been measured,, be decided to be high pressure and low pressure at the corresponding percentage point.The peak dot of envelope is mean pressure.This method, more accurate for the people who meets this model.As not meeting this model, measurement error is very big.No cardiovascular diseases's normal person generally meets, and has cardiovascular diseases's people mostly to depart from model, and the rule discreteness of envelope is very big.Non-percentage ratio method is also like this, so by the method for mathematical model limitation is arranged.Hospital's cardiovascular patient needs most the measurement blood pressure, and the accuracy of this method and reliability are to be subjected to very big query.Another kind of, do not set up model, by measure seeking the eigenvalue of envelope, i.e. systolic pressure, mean pressure, diastolic pressure.This determination methods defective is that not obvious as the eigenvalue of envelope, error in judgement is bigger.The eigenvalue of finding the considerable part people in the experiment is not obvious.Another shortcoming of vibration oscillographic method is that strong excessively to the dependence of envelope in measuring process, if any interference, erroneous judgement might appear in the envelope of surveying, or causes measuring failure.
For overcoming above-mentioned shortcoming, the engineer of each producer does a lot of work on software and hardware both at home and abroad, introduces a lot of advanced algorithms, but it is little to produce effects.The clinician often says that electronic blood pressure measurement is insincere, can only be as a reference.
Summary of the invention
The purpose of this invention is to provide a kind of measurement result relatively accurately and measure blood pressure measuring device and blood pressure measuring method easily.
For achieving the above object, the present invention takes following design: a kind of blood pressure measuring device, the big cuff that comprises a blocking blood flow, the air vesicle that has a band trachea in this big cuff, it is characterized in that: it comprises that also one is used to survey the little cuff of pulse wave, the ballonet that has a band trachea in this little cuff, a pick off that is used to survey pulse signal that is connected with described ballonet.
It also comprises an air valve, and described air valve is connected with the trachea of described air vesicle and ballonet respectively by connection tube.
Described pick off is a pressure transducer.
Described pick off is a sound transducer.
Be separated from each other between described big cuff and the little cuff.
Described big cuff and little cuff place in the same bag shape body.
Be connected by connecting band between described big cuff and the little cuff.
A kind of blood pressure measuring method comes blocking blood flow with big cuff, and therefrom extracts pressure value by pressure transducer or Pressure gauge, surveys the signal of pulse with little cuff and pick off.
Advantage of the present invention is: 1, blood pressure measuring device of the present invention, the big cuff that comprises a blocking blood flow, the air vesicle that has a band trachea in this big cuff, one is used to survey the little cuff of pulse wave, the ballonet that has a band trachea in this little cuff, a pick off that is used to survey the pulse variation that is connected with ballonet.The present invention comes blocking blood flow with big cuff, survey pulse wave with little cuff, because of the ballonet of little cuff can be around arm one circle, so need not resemble with stethoscope and need capturing position, and can reduce error as measurement point with little cuff, and can detect pulse wave at an easy rate, and further survey the signal of pulse by pick off, it is more accurate to be used as pressure value by the pressure value that extracts gas in the air vesicle.2, blood pressure measuring device of the present invention, it also comprises an air valve, air valve is connected with the trachea of air vesicle and ballonet respectively by connection tube, therefore can give the inflation of air vesicle and ballonet simultaneously, and is easy to operate, the save operation time.
