Good day, today I will talk about the product structure of the electronic blood pressure monitor.
product structure:
There are three generations of electronic sphygmomanometers. The following describes its structure according to the third-generation electronic sphygmomanometer.
1. The first generation of electronic blood pressure monitor (G1-NIBPM)
The main components of the composition: fast pressurizing air pump or manual pressurizing pump, electronic quick exhaust valve, mechanical fixed speed exhaust valve, air pressure sensor
Due to the use of rubber valves that are prone to aging, they are generally considered inaccurate. This technology has been eliminated by mainstream electronic sphygmomanometer manufacturers.
2. The structure of the second-generation electronic blood pressure monitor (G2-NIBPM)
Main components: pressurized air pump, electronically controlled exhaust valve, air pressure sensor
Technology used: MWD technology (measured during decompression)
Measurement characteristics: Due to the use of electronically controlled exhaust valve servo technology (ECV SERVO TECHNOLOGY), the speed of fixed-speed exhaust is truly fixed, and can be intelligently pressurized according to the blood pressure of the measurer, and the measurement result is more stable (other Except for influencing factors).
Feature 1: Only one exhaust valve is used-electronically controlled exhaust valve, which is also used for fixed speed exhaust and rapid exhaust at the end of the measurement;
Feature 2: Intelligent pressure. That is, the sphygmomanometer will make a rough judgment on the measurer’s blood pressure in advance during the pressurization process, so as to determine the final pressure value that needs to be added, usually the pressure value is added to the measurer’s systolic pressure +30mmHg;
Feature 3: The deflation speed can be stabilized at 3~4mmHg/s from the beginning.
The second-generation electronic sphygmomanometer (G2-NIBPM) is characterized by its electronically controlled exhaust valve (ECV) and electronically controlled exhaust valve servo technology. Internationally, there are roughly the following companies that master “Electronic Control Exhaust Valve (ECV) and Electronic Control Exhaust Valve Servo Technology”: Takrl Technology, Omron, and Panasonic.
The first-generation and second-generation measurement technologies are collectively referred to as MWD technology (measurement during decompression), which corresponds to the following third-generation MWI technology (measurement during pressurization).
3. The structure of the third-generation electronic sphygmomanometer (G3-NIBPM)
Main components: servo pressurized air pump, electronically controlled exhaust valve, air pressure sensor
Technology used: MWI technology (measured when pressurized)
Measurement features: pressurize at a constant speed, and measure blood pressure during the pressurization process.
Feature 1: Use a servo pressurized air pump-control the pressurization speed, and measure blood pressure during the pressurization process;
Feature 2: Use only one exhaust valve —— electronic quick exhaust valve for quick exhaust at the end of the measurement. The technical difficulty of this generation of electronic sphygmomanometers is MWI technology (pressure simultaneous measurement). The companies that master this generation of technology in the world are roughly as follows: Takrl, Omron, Panasonic, Aintan.
The third-generation electronic sphygmomanometer (G3-NIBPM) is characterized by only using an electronically controlled quick exhaust valve and -MWI technology (pressure simultaneous measurement technology).
4. The structure of the fourth-generation electronic blood pressure monitor (G4-NIBPM)
Main components: integrated gas circuit
Technology used: MWI technology (measured when pressurized)
Measurement features: pressurize at a constant speed, and measure blood pressure during the pressurization process.
Feature 1: The entire integrated gas path can be scaled down, so that the entire gas path can be scaled down to occupy only part of the space of an ordinary watch; it lays the foundation for a wearable watch-type blood pressure monitor (blood pressure watch).
The structural feature of the fourth-generation electronic blood pressure monitor (G4-NIBPM) is that it is extremely compact, and the entire gas path is slightly reduced to occupy only part of the space of an ordinary watch.
Well, today’s knowledge about the product structure of electronic blood pressure monitors is introduced here. Next time I will continue to talk about the suitable people for different blood pressure monitors
