Description
Technical field
This utility model is about a kind of arm-type sphygomanometer, especially refer to that a kind of thin bag combines with sphygomanometer body one and the arm-type sphygomanometer of the convenience type that thin bag width is narrower, not only processing ease, volume little, carry easily, cost of manufacture is low, and is and comparatively comfortable and measure accurately when measuring blood pressure.
Background technology
Because the modern is for the attention of health and the progress of medical skill, the idea of nursing at home comes into one's own day by day.Even, also can directly carry out the monitoring or the test of some physiological detection at home by easy device no matter be that patient or healthy people wish not in hospital.Therefore, now general sphygomanometer just can be measured blood pressure and little by little is designed to only need easy device can finish measurement from being operated by the professional person originally, and the tester can finish measurement according to the operating procedure of putting down in writing on the workbook.Not only do not need hospital, and common people can operate.
Known have various blood pressure measuring method with the device can be in order to record pressure value, modal mode is the flat thin bag of tying up at upper arm with (cuff) mostly, via the endarterial blood flow of compressing arm behind the inflation, afterwards again by the gentle thin bag of interior gas that releases, utilize stethoscope to listen the sound of pulse simultaneously, promptly so-called " Korotkoff sound ", this " Korotkoff sound " is to follow blood to recover the sound that proper flow produced, pressure in thin bag reduces further, just can can't hear this " Korotkoff sound ".So when hearing primary " Korotkoff sound ", its pairing thin bag pressure representative be systolic pressure, and when can't hear " Korotkoff sound ", just can measure diastolic pressure.More than the mode of this measurement blood pressure generally be referred to as " method of auscultation (auscultatory method) ".In addition, the auscultation mode also can be applicable on the electronic blood pressure measurement device, utilizes an air pump will approach bag inflation automatically, again by a microphone with " " Korotkoff sound " convert electric signal to and detect by a circuit, just can measure systolic pressure and diastolic pressure.
At present the electronic type blood pressure meter can be divided into Wrist blood pressure meter and arm-type sphygomanometer generally, promptly by wrist or arm measure pressure value.It is general because wrist is thin compared to arm, therefore the Wrist blood pressure meter thin bag of arranging in pairs or groups can match and width is comparatively narrow, therefore the hard pressed region area of testee is less, so testee is comparatively comfortable when measuring, comparatively not roomy like the designed thin bag of present arm-type sphygomanometer, the suffered compressing of testee is big, comparatively uncomfortable when therefore measuring, especially for patients with hypertension, then the bigger testee that causes of the pressure of its required pressurization is more uncomfortable.Yet, because arm approaches the heart place, therefore comparatively correct by the pressure value result that arm-type sphygomanometer measured, and wrist is because far away apart from the heart distance, and the blood vessel that distributes is thinner, and what therefore will measure accurately must more progressive technology just can reach, so, comparatively comfortable when though Wrist blood pressure meter measures, but still not like the high accuracy of arm-type sphygomanometer.On the other hand, because the thin bag of general known arm-type sphygomanometer is separated from each other with the sphygomanometer body, and shared volume is big, therefore operation is difficult for and carries inconvenience, thus the correct measurement that how to reach arm-type sphygomanometer again can be more comfortable and processing ease be that relevant manufacturer needs improvements.
