The electronic sphygmomanometer is a medical device that utilizes modern electronic technology and the principle of indirect blood pressure measurement for blood pressure measurement.
Electronic sphygmomanometer has arm, wrist, watch type; its technology has experienced the most primitive first generation (mechanical fixed-velocity exhaust valve), the second generation (electronic servo valve), the third generation (pressurized synchronous measurement) and the fourth generation (integrated airway) development.
Usually consists of an obstruction cuff, a sensor, an inflation pump, and a measurement circuit. An electronic device for blood pressure measurement using the oscillometric method, the Koch sound method, or a similar non-invasive blood pressure indirect measurement principle.
Precautions for use
1. Rest quietly for a few moments before measurement to eliminate the effects of tension and exertion on blood pressure;
2. The examinee's arm should be at the same height as the heart;
3. The cuff should be placed in a flat position, and the tightness of the cuff should be appropriate for inserting two fingers;
4.
