Blood pressure meter application case

The average growth rate of my country's medical device industry is about 25%, which is much higher than the average growth rate of the national economy in the same period. The increase of GDP per capita has directly led to the rapid growth of medical expenses. According to the "2014-2018 my country Medical Device Industry Market Prospect and Investment Forecast Analysis Report" by Qianzhan Industry Research Institute, the total sales revenue of China's medical device industry in 2012 has exceeded 100 billion yuan, a year-on-year increase of more than 20%. Policy support, population structure, consumption upgrade and many other factors predict that China's medical devices will maintain rapid growth in the next 5-10 years, and the industry as a whole will still maintain a growth rate of more than 20%. It is expected that the market size will reach 3400 by 2015. billion. my country's medical device industry started late, but with the development of the economy and the improvement of people's health awareness, blood pressure instruments will usher in a high demand.

The working principle of the blood pressure meter is different according to the Korotkoff sound method and the oscillation method. "Korotoff sound method" Korotkoff sound method is to measure blood pressure by listening to the sound (Krotov sound) made by blood flowing in blood vessels; "oscillation method" is due to the effect of blood flow sent by the heart, the blood vessels in the arm band vibrate . The oscillation method is to detect the waveform of this vibration to obtain the blood pressure value. Unaffected by external noise. Hospitals abroad mainly use electronic sphygmomanometers. Since a stethoscope is not used, the armband is easy to operate and anyone can use it.

The classification of blood pressure meters can be distinguished according to different measurement methods and working principles: according to different measurement methods, blood pressure meters can be divided into two types: wrist blood pressure meters and arm blood pressure meters; according to different working principles, they can be divided into three types Types: traditional mercury column (mercury column) type sphygmomanometer, barometer (spring) type sphygmomanometer, electronic sphygmomanometer. The sphygmomanometer has the functions of measuring blood pressure and 24-hour monitoring.

         Sphygmomanometer structure

         Cuff: There is an inflatable rubber bag inside, which is tied to the upper arm during measurement;

         Rubber ball: Oval shape, squeeze the rubber ball by hand to inflate the cuff;

         Rubber tube: There are two, one connects the rubber ball and the cuff, and the other connects the cuff and the mercury column scale, which is the passage of gas;

         Valve: There is an air filter inside, close the valve, inflate the cuff, measure blood pressure.
