Description

Sounding mercury sphygmomanometer

Technical Field

The utility model relates to a mercury sphygmomanometer field, in particular to formula of can making a sound mercury sphygmomanometer.

Background

Blood flows in blood vessels like water flows in a flat and smooth river channel, and usually has no sound, but when the blood or the water forms vortex through a narrow pipeline, the blood or the water can make a sound, the sphygmomanometer for measuring the blood pressure of a human body is designed according to the principle, the blood pressure is measured clinically by adopting an indirect measurement method, and the sphygmomanometer is composed of a balloon, a cuff and a pressure detector. The two tubes of the rubber bag of the cuff are respectively connected with the balloon and the pressure detector to form a closed pipeline system. The pressure gauge has two types, namely a mercury column type gauge and a spring type gauge.

When measuring blood pressure, the cuff wrapped on the upper arm is inflated and pressurized by a balloon, and the pressure acts on the brachial artery through soft tissue. When the pressure is higher than the systolic pressure, the balloon is deflated slowly, the pressure in the cuff is reduced, when the pressure in the cuff is equal to or slightly lower than the systolic pressure, blood can burst the blocked blood vessels to form vortex along with the systolic ejection of blood, the stethoscope begins to hear the pulsating sound, and the pressure value indicated by the pressure detector is equal to the systolic pressure. And continuously and slowly deflating to gradually reduce the pressure in the cuff, and when the pressure in the cuff is lower than the systolic pressure but higher than the diastolic pressure, the heart can hear a sound once per contraction. When the cuff pressure is reduced to be equal to or slightly lower than the diastolic pressure, the blood flow is unblocked again, the sound emitted along with the heartbeat is suddenly weakened or disappears, the pressure value indicated by the pressure detector is equivalent to the diastolic pressure, the blood pressure measured by an indirect method is an approximate value, and the accuracy degree of the approximate value is in certain relation with the measurement technology. During measurement, the wound cuff is unfolded to keep the zero points (or spring manometers) of the upper arm, the heart and the mercury manometers at the same level as much as possible, and the air is not deflated too fast, otherwise, a large error occurs.

At present, when a medical worker measures blood pressure of a hypertensive patient by using a mercury sphygmomanometer, a stethoscope is generally used for listening to sounds generated by vortex formed by blood vessels when heart contracts and shoots blood, and then the blood pressure value is determined, however, the mercury sphygmomanometer is used by the patient or family members, the sounds generated by the stethoscope cannot be accurately captured, measurement errors are caused, particularly, the sounds generated by the stethoscope are more difficult to capture for the patient with poor hearing, and therefore, the problem that the sounding mercury sphygmomanometer which is convenient to measure and accurate in measurement needs to be urgently solved is provided.
