The first generation of sphygmomanometers - mercury sphygmomanometer
Mercury sphygmomanometer is a kind of sphygmomanometer, is the main structure of the mercury sphygmomanometer, which was born in 1928 in the United Kingdom. The earliest sphygmomanometers were used to measure the blood pressure of horses, and were later used to measure human blood pressure.
A common failure of mercury sphygmomanometers is the leakage of mercury, which can lead to inaccurate measurements and large errors.
The second generation of sphygmomanometer-electronic sphygmomanometer
Electronic sphygmomanometer is a medical device that utilizes modern electronic technology and the principle of indirect measurement of blood pressure 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.
Third Generation Sphygmomanometer-Smart Connected Sphygmomanometer
Smart Sphygmomanometer is the use of a variety of means of communication (Bluetooth, USB cable, GPRS, WiFi, etc.), the electronic sphygmomanometer's measurement data through the wisdom of the processing of the uploaded to the cloud, to achieve real-time or automatically timed measurements and record the value of the user's blood pressure, intelligent analysis of blood pressure It is a kind of intelligent medical equipment that can continuously and dynamically monitor hypertensive patients and concomitant diseases in a timely manner.

Kangshang Intelligent Sphygmomanometer
The means of communication of intelligent sphygmomanometer generally include Bluetooth, USB, GPRS (2G/3G) and WiFi.
Sphygmomanometers are classified into arm sphygmomanometers, wrist electronic sphygmomanometers, and watch sphygmomanometers according to the different parts of the measurement site.
Arm sphygmomanometer
The technology of arm sphygmomanometer has gone through the development of the first generation of "air-core", the second generation of "air-core-less" and the third generation. Its advantage is that it requires very low posture for measurement, so you don't have to worry about the effect of posture on the error; its disadvantage is that it is a little bit larger, so you have to take off your clothes in winter.
Wrist sphygmomanometer
Wrist sphygmomanometer is a wrist artery "pulse pressure value", so the measurement value will be biased, but wrist sphygmomanometer has the characteristics of easy to carry, so it is more suitable for business trips, travelers use.
Watch sphygmomanometer
Watch sphygmomanometer is a kind of electronic sphygmomanometer that is comparable in size to an ordinary watch, and can be worn on the wrist for a long period of time like a watch. A wrist sphygmomanometer should not be treated as a watch sphygmomanometer.
Watch sphygmomanometers can be divided into the following categories: oscillometric watch sphygmomanometers, tension method watch sphygmomanometers.
