Digital Blood Pressure Sphygmomanometer

The main principle of Digital Blood Pressure sphygmomanometer refers to the process of measuring the blood flow pressure during this period by compressing the local artery with air pressure and preventing the pulsation of the local artery by applying pressure. The measurement principle of sphygmomanometer can be divided into auscultation and oscillography.

Advantages:

simple operation and intuitive reading

It can be measured automatically just by turning on the switch. It is suitable for family use. However, the electronic sphygmomanometer also has the disadvantage of large error, which also needs to be calibrated based on the standard mercury sphygmomanometer. Its principle includes auscultation (also known as Coriolis sound method) or oscillography (also known as oscillation method), which is mainly composed of gas pressure sensor, pressurized micro air pump, electronically controlled exhaust valve, relevant software, mechanical slow exhaust valve and solenoid fast exhaust valve.

Matters needing attention：

Because of the blood flow, the blood pressure measured by the left hand and the right hand will be different; Usually, the blood pressure value of the left hand is slightly higher than that of the right hand, but the difference between 10 ~ 20mmhg is normal. However, the high measurement data shall prevail when recording. If the difference between two hands exceeds 40 ~ 50mmhg, it may be the problem of vascular obstruction. It is best to consult a doctor to find out the cause.

Blood pressure should not be measured only once. Blood pressure should be measured several times a day and recorded in order to understand the change of blood pressure within a day.

Electronic sphygmomanometers are divided into wrist type and arm type. Although wrist type is more convenient to use, it is usually far away from the center, and the greater the difference in measurement results; It is recommended to test on site when purchasing. If there is little difference between the results measured by arm and wrist, both can be used; If the difference is large, it is better to choose arm posture.

Before and after the mercury sphygmomanometer is used, the medical staff should always check the blood pressure and keep the scale clear. The pipe string should be cleaned regularly with a full strip. There should be no bubbles when the pressure is about 200 mmgh. If there are bubbles during the pressure process, stop the pressure for inspection and maintenance

It's best to measure blood pressure when you feel relaxed at home When some people measure their blood pressure in medical institutions, they will feel nervous in the face of medical staff wearing white clothes, which will increase their blood pressure. Medicine is called "white hypertension". Measuring blood pressure at home can overcome this situation.

The traditional mercury sphygmomanometer will be affected by thermal expansion and cold contraction, and should be corrected to zero once every half a year.

The electronic Digital Blood Pressure sphygmomanometer will be affected by the aging of components and other components, and needs to be calibrated once a year on average.
