Their technology has gone through the development of the most primitive first generation, the second generation (semi-automatic sphygmomanometer), and the third generation (intelligent sphygmomanometer). Electronic sphygmomanometers have become the main tool for self-testing blood pressure at home. Electronic sphygmomanometers are also increasingly used in hospitals and other medical institutions. Because nowadays, some of the blood pressure monitor enterprises with more sound sales network and bigger ones usually have after-sales service for calibration of blood pressure monitors as well. If this perspective to seek electronic sphygmomanometer calibration, which is still more likely.
First of all, human blood pressure is dynamic, and fluctuations within a certain range of each measurement are normal, and secondly, the sphygmomanometer needs to be calibrated every few years to ensure the accuracy of blood pressure measurements. Worried that the sphygmomanometer is not allowed, I first inquired about contacting the after-sales service number of the head office of Yuyue, and then got through, telling me that the head office in Danyang, Zhenjiang, Jiangsu Province, where I sent it, could calibrate it. You can mail to Ruibao, complete the calibration calibration, they have professional calibration equipment, in accordance with the national calibration regulations to calibrate.
Then rest for another 3 minutes and measure the 3rd time with a mercury column sphygmomanometer. The difference between the average of the first and third measurements, compared with the second measurement with the electronic sphygmomanometer, should generally be less than 5 mm Hg. The popularization of health knowledge and enhancement of self-care awareness, sphygmomanometer has gradually become a necessity for home life, many patients and some healthy people are at home to monitor their own blood pressure. However, in order to do an accurate measurement of blood pressure, there are some issues that should be clarified as well.
Municipal metrology bureaus around the world can calibrate blood pressure monitors, and most of the municipal metrology bureaus in Shandong Province are free to the public to calibrate blood pressure monitors. Of course, this practice usually need to bring their own electronic sphygmomanometer to the hospital to find the hospital to do comparison, it should be noted that this process of measuring blood glucose can only be used to do proofreading electronic sphygmomanometer, and can not be compared with their own blood pressure usually measured at home I went to the City Measurement and Inspection Center has asked the mercury column can be calibrated, the electronic quiz can not be, and then did not inquire about what place to do this work.
