Electronic blood pressure meter technology development and generation division
Electronic blood pressure meter technology development and intergenerational division, first of all, electronic blood pressure monitor technology from principle through auscultation ( also called Korotkoff sound method ) and oscillometric method ( also called oscillation method ) two phases of development, at present, only a handful of Companies in the electronic sphygmomanometer using the auscultatory method principle, and the most mainstream electronic blood pressure meter manufacturing enterprises are using principles of oscillometric method. In view of the current mainstream companies are using the principles of oscillometric method, so here to say technology generation division is the oscillometric method ( also called oscillation ) electronic blood pressure monitor technology generation division.
One, the first generation of electronic blood pressure monitor ( G1-NIBPM ) techniques used: MWD ( vacuum measurement ) using the main components: rapid pressurizing pump, electronic quick exhaust valve, exhaust valve, mechanical type constant air pressure sensor characteristics: rapid pressurized to a pressure value, through a mechanical speed exhaust valve at the speed of 2~7mmHg/s release, and then deflated during the course of the blood pressure measurement.
Characteristics of 1: using two exhaust valve - - - - - - Electronic quick exhaust valve, exhaust valve mechanical speed;
Characteristics of 2: the initial pressure is mostly set at around 200mmHg, emphasizing the compression speed, usually within 10 seconds to reach the set pressure value;
Characteristics of 3: pressurized just stop, discharging speed of more than 7mmHg/s, after a few seconds to roughly stable in 2~7mmHg/s. This generation of products due to a mechanical type speed exhaust valve instability ( principle of defects), will generally improve the initial pressure, such as most of the current domestic sphygmomanometer, initial pressure pressure are mostly set in the 190~200mmHg, which to some extent, can overcome the pressure just stops bleeding caused by speed measurement instability problems. Its defect is the user's arm ( or wrist ) is obviously oppressive feeling, at the same time as the mechanical speed of exhaust valve of instability, the measurement results are sometimes unstable.
Currently a number of purchases of electronic blood pressure monitor scheme of the manufacturer, its technical level in the most first generation. And all the solutions provider also is on the hand only a generation scheme.
In two, the second generation of electronic blood pressure monitor ( G2-NIBPM ) techniques used: MWD ( vacuum measurement ) using the main components: the pressure pump, electronic control valve, pneumatic pressure sensor for measuring features: adopts electronic control valve servo technology ( ECV SERVO TECHNOLOGY ), constant speed exhaust speed truly constant speed, and can according to the measurement of blood pressure intelligent pressure, measurement results are more stable ( other factors except).
Characteristics of 1: use only one exhaust valve - - - - - - - electronic control the exhaust valve, exhaust and at the same time for constant speed measured at the end of the quick exhaust;
2: characteristics of intelligent pressure. The sphygmomanometer in the compression process in advance on the measurement of blood pressure in a rough judge, the need to add to the value of pressure, usually added to the measured pressure values of systolic blood pressure is about +30mmHg; features 3: discharging speed can be a starting stability in 3~4mmHg/s.
This generation of electronic blood pressure monitor, technical difficulty is the electronic control valve servo technique, the first generation and the second generation of measurement technique is also called MWD ( vacuum measurement ), and the third generation MWI Technology ( pressure corresponding measurement ).
In three, the third generation of electronic blood pressure monitor ( G3-NIBPM ) techniques used : MWI ( pressure measurement ) main components used are: servo pressure pump, electronic control valve, pneumatic pressure sensor characteristics : uniform pressure, and in the compression process in blood pressure measurement.
Characteristics of 1 : the use of servo pressure pump - control pressure speed, and the pressurized process characteristics of blood pressure measurement; 2: use only one exhaust valve, quick exhaust valve for electronic, measured at the end of the quick exhaust.
This generation of electronic sphygmomanometer technical difficulty is MWI Technology (pressure synchronous measurement ), the master of this generation of technology companies are the following several: OMRON, Panasonic, AMS and, superior medical, KINGYIELD.
On the three generation of electronic blood pressure monitor technique is used according to the current world mainstream electronic blood pressure monitor manufacturers products to judge, the first generation of electronic blood pressure monitor technology basically at the edges is eliminated; the second generation of electronic blood pressure monitor technology is mainly used in the upper arm type electronic blood pressure meter; the third generation of electronic blood pressure monitor technology is mainly used in wrist electronic sphygmomanometer.
