Blood-pressure measuring instrument and measuring method

Abstract

The invention relates to a medical instrument for measuring the blood pressure and a blood-pressure measuring method. The blood-pressure measuring instrument consists of a pressure measuring part and an auscultation part, wherein the pressure measuring part adopts a pressure gauge, and an electric sensing element also can be adopted to convert the pressure value to a visible number. The pressure measuring part is vertically (or horizontally) overlapped with the auscultation part into a whole. A gold standard-Korotkoff-Sound auscultatory method for measuring the blood pressure is adopted by the instrument. When the blood-pressure measuring instrument is used for measuring the blood pressure, the blood-pressure measuring instrument is arranged on brachial artery of the human body to be leveled to the heart, pressure is applied by direct pressing (rather than by inflation of a sleeve band), so the instrument squeezes the brachial artery to completely stop the blood stream, then the pressure is slowly decreased until the auscultation part can hear the pulse sound, and the current measuring value of the pressure measuring part is the highest value (systolic pressure) of the blood pressure; and the pressure is continued to decrease slowly until the pulse sound completely disappeares, and the current measuring value of the measuring part is the lowest value (diastolic pressure) of the blood pressure. The instrument and the measuring method are free from the mercury pollution and are free from the assistance of the sleeve band, so the measuring instrument is convenient to carry, is simple and quick to operate and is accurate to measure the blood pressure.

Description

technical field [0001] The invention relates to a medical instrument and method for measuring blood pressure. The instrument has no mercury and no cuff, and the method can measure blood pressure more quickly and accurately. Background technique [0002] In 1905, the Soviet doctor Korotkoff discovered the Korotkoff sound and established the Korotkoff sound auscultation blood pressure measurement technology, making it the "gold standard" for clinical blood pressure measurement [1] , the method consists of a sphygmomanometer, a cuff, and a stethoscope. So far, non-invasive blood pressure measurement has been widely accepted and applied clinically. At present, known Korotkoff sound auscultation sphygmomanometers include mercury (mercury) sphygmomanometers and barometer sphygmomanometers, both of which are currently most commonly used in clinical practice. Among them, mercury sphygmomanometers are considered to be the "gold standard" of indirect blood pressure measurement method...

Problems solved by technology

[0003] In order to overcome the negative impact of mercury on the environment and human body in current mercury sphygmomanometers, and the disadvantages that mercury sphygmomanometers, barometer-type sphygmomanometers and electronic sphygmomanometers all need cuff-assisted measurement, the invention provides a mercury-free, cuff-free This instrument avoids mercury pollution and does not need the assistance of a cuff. By directly changing the "pressing" force, the blood flow of the brachial artery can be blocked and recanalized, which can measure human blood pressure more accurately and quickly.
