Sphygmomanometer is a diagnostic instrument for measuring human blood pressure. It has the characteristics of small size and light weight, and the effect is the same as mercury sphygmomanometer.

Precautions for blood pressure measurement:

Blood pressure should be measured in a quiet environment.

2, because the body's blood pressure changes throughout the day, so should choose to be measured at the same time every day.

3. Subjects should keep quiet in a relaxed state, preferably without talking or activities.

4. Wear loose clothes.

[precautions for blood pressure measurement] :
   Blood pressure should be measured in a quiet environment. Because blood pressure changes throughout the day, you should choose to measure it at the same time every day. Subjects should be quiet in a relaxed state, preferably without conversation or activity. Wear loose clothing.
[measurement method] :
    1. Before the use of blood pressure meter, check first, the normal use of blood pressure meter usually refers to the dial in the \"0\" position, pressure after the reaction is flexible, and still can return to the original \"0\" position.    2. Please sit at the table and place your left arm on the table in a comfortable position.   3. Adjust the arm and keep it at the same height as the heart. If the height is not high enough, you can add cushions under the arm.    4. Flatten the arm band and allow the middle of the air band to face the brachial artery. Tie the lower edge of the arm band up to 2 to 3 cm above the elbow socket to the upper arm.    5. Insert the earpiece of the stethoscope into the armband and place it on the brachial artery at the elbow.    6. Slowly inflate the brachial artery belt with the latex ball, and pay attention to monitoring. When the brachial artery pulse disappears, increase the pressure by 2.5kpa-4kpa (20mmhg-30mmhg) and stop the pumping.    7. After the pressure stops, the air in the arm belt is slowly released at the rate of 0.3kpa-0.6kpa (2mmhg-4mmhg) per second, so that the blood pressure indicator gradually drops.    8 in the process of falling through the stethoscope to hear the first pulse of sound when the pressure value of the needle, that is, systolic pressure.    9. When the pulsatile sound becomes a murmur after gradual enhancement, the tone suddenly becomes stuffy and gradually disappears. When the sound is not heard, it is called diastolic pressure.

   * when measuring blood pressure, repeat 2 to 3 times, taking the average reading as the blood pressure value.

   * the back of the blood pressure meter case is equipped with a metal hook, which can be hung on the arm belt when used, making the reading more convenient.  

    * the blood pressure gauge arm is equipped with Velcro, and the strap is convenient and convenient
