Hua'an is a upper arm blood pressure monitor chinese manufacturer
Upper arm blood pressure monitor its technology experienced a "sparkling core" first generation "airless core" of the second and third generation of development, the advantage of low requirements on the measurement position, do not worry about the position of the error impact; drawback is the volume slightly, to take off their clothes for winter use, time use 4 AA alkaline batteries, power consumption, high cost.
Upper arm blood pressure monitor is divided into three generations, namely G1-NIBPM structure, G2-NIBPM structure and G3-NIBPM structure. The first generation of electronic sphygmomanometer G1-NIBPM structure
Constitute the main components: the rapid pressurization pump or manual pressure pump, electronic quick exhaust valve, exhaust valve mechanically fixed speed, air pressure sensor
Technology used: MWD technology
Measuring characteristics: rapid pressurization to a pressure value, a constant speed by a mechanical speed of the exhaust valve at 2 ~ 7mmHg / s deflated and deflated in this blood pressure measurement process.
Currently there are three kinds of forms sphygmomanometer, one upper arm, the second is the wrist, three finger style. These three forms of sphygmomanometer, electronic sphygmomanometer in which the fingers, even for healthy people, but also has been proven to not be used. Of particular note that Wrist Blood Pressure Monitor, does not apply to patients suffering from blood circulation disorders, such as diabetes, high cholesterol, hypertension, atherosclerosis and other diseases will accelerate, causing peripheral circulatory disorders. The patient's wrist with arm blood pressure measurements varied widely. Recommended in these patients and the elderly should choose Arm Blood Pressure Monitor to use. In addition, field measurements before buying should look to choose their own electronic sphygmomanometer.
