Wrist and upper arm sphygmomanometers

Wrist sphygmomanometer measurement is in the sphygmomanometer with a detector, the detector can be wrapped around the wrist, you can measure the pressure changes in the arterial blood vessels, the heart outputs blood to the outside, blood pressure to the front of the blood vessels will be reflected back to the principle of measurement of whether there is high blood pressure or low blood pressure. The advantage is that it is easy to carry, can be measured anytime and anywhere, especially in winter when it is inconvenient to take off the clothes, convenient for the elderly to use. The upper arm sphygmomanometer is worn through the cuff at the elbow joint, through the automatic pressurization and decompression, directly measuring the high pressure value, low pressure value and the number of pulses per minute and displayed on the LCD screen. The disadvantage is that the volume will be relatively large, and when used in winter, the need to undress, the convenience of the elderly use is not as strong as the wrist.

Wrist and arm sphygmomanometer, the accuracy of these two sphygmomanometers, arm sphygmomanometer will be more reliable, and the use of ways and means is relatively simple.
