Electronic sphygmomanometer is a medical instrument that uses modern electronic technology and indirect blood pressure measurement principle to measure blood pressure.
Electronic sphygmomanometer can be divided into arm type, wrist type and watch type; Its technology has experienced the development of the first generation (mechanical constant-speed exhaust valve), the second generation (electronic servo valve), the third generation (pressurized synchronous measurement) and the fourth generation (integrated gas circuit).
It usually consists of blocking cuff, sensor, air pump and measuring circuit. An electronic device that measures blood pressure by oscillometric method, acoustic cancellation method or similar non-invasive indirect blood pressure measurement principle.
