Electronic sphygmomanometer is a medical device that uses modern electronic technology and indirect blood pressure measurement principle to measure blood pressure,
It is usually composed of blocking cuff, sensor, air pump and measuring circuit. Electronic equipment for blood pressure measurement using oscillographic method, Kirschner method or similar non-invasive indirect blood pressure measurement principle.
Nowadays, the electronic sphygmomanometer has realized automatic intelligent measurement. The measured data can be automatically transmitted to the health management platform through the network, and the generated health data report will be fed back to users. The measurement results are more accurate than the traditional electronic sphygmomanometer because of the advanced technology.
The technology of the upper arm sphygmomanometer has experienced the development of the first generation with air core, the second generation and the third generation without air core. Its advantages are that the requirements for measuring posture are very low, and there is no need to worry about the influence of posture on the error. The disadvantage is that the volume is slightly larger, and you need to take off your clothes when you use it in winter, and use four 5 alkaline batteries at a time, which consumes a lot of electricity and costs a lot.
There are three forms of sphygmomanometer: the upper arm type, the wrist type and the finger type. These three types of sphygmomanometers, including digital sphygmomanometers, have been proved to be unusable even for healthy people. It should be noted that wrist electronic sphygmomanometer is not suitable for patients with blood circulation disorders, such as diabetes, hyperlipidemia, hypertension and other diseases, which will accelerate arteriosclerosis and cause peripheral circulation disorders. The blood pressure measurements on the wrist and the upper arm were quite different in these patients. It is suggested that these patients and the elderly should choose arm type electronic sphygmomanometer. In addition, before purchase should be measured on the spot, in order to choose their own electronic sphygmomanometer.
How to use arm blood pressure monitors ?
Before using electronic sphygmomanometer to measure blood pressure, we should rest for a few minutes to eliminate the influence of fatigue and excitement on blood pressure. If the exercise, you must rest for 30 minutes.
In a warm room, the blood pressure is measured at the same time every day. The rise of blood pressure after waking up in the morning or taking a lunch break conforms to the general rule of blood pressure fluctuation, which can reflect the highest blood pressure of the tested person most truly.
The arm belt should be properly bound, and the main body in the center of the arm belt is at the same level with the heart.
Before the measurement, relax and take a few deep breaths; take a 5-minute interval for continuous measurement; do not speak or shake your body during the measurement.
Arm cuff should not be too tight or too loose, so that it can be easily put into the index finger, and the trachea should be located on the inner side of the arm.
1. Unfold the arm band of the upper arm type electronic sphygmomanometer to prevent the belt from falling off the metal collar.

2. When measuring, if the weather is not cold, bare your arms as much as possible. If you wear more clothes, do not roll up the cuffs, but take off the clothes.
3. Put the arm strap of the sphygmomanometer on the left arm. The bottom of the armband should be 2-3cm higher than the elbow. The green mark should be on the inside of the arm in Egypt. The air pipe must be on the extension line in the middle finger direction.
4. Hold the end of the armband of the sphygmomanometer, and while pulling, wrap the armband tightly around the arm.
5. Upper arm sphygmomanometer can also be measured on the right arm, according to the above steps, you can accurately measure the blood pressure value.
