Simple electronic blood pressure monitor quality of the five methods
The following is a simple electronic blood pressure monitor quality of the 5 methods:
One, to confirm the purchase of electronic blood pressure monitor manufacturer whether to obtain certification
At present, all countries of the world, the medical equipment detection and supervision are very strict.
As a general medical examination equipment of electronic sphygmomanometer measurement certificate, production license, product registration certificate and domestic production enterprises must have.
In addition to the above domestic and international certification certificate, has very important reference value, it directly reflects the manufacturers in the international market competitiveness. The medical aspects of international of two big mainstream certification, one is the EU's Medical certification CE ( specialized medical equipment for a special CE, different from the ordinary electronic products or massage equipment and other products CE certification ), obtain certification for the company get a certification number; another is the United States FDA certification, certified manufacturer to obtain a 510 ( k ) number, this number in the FDA official website inquiries to.
Two, confirm the electronic sphygmomanometer pressure when the noise size
Electronic blood pressure meter noise mainly comes from the measurement of the pressurization. Good quality electronic blood pressure meter pressure uniform, stable, powerful, low noise. It directly reflects the manufacturer 's technical standards and the level of manufacturing technology.
From a technical perspective, the fixed pressure to a preset pressure value ( about 200mmHg) of the first generation of electronic blood pressure monitor on noise control is the worst, as when pressurized loud noise; and the use of intelligent pressure and electric servo technology of the second generation of electronic sphygmomanometer and the use of compression with the step of measuring technology of the third generation of electronic sphygmomanometer, in noise control performance are very good.
Three, confirm the electronic sphygmomanometer to pulse number measurement is accurate
Pulse measurement is oscillometric electronic sphygmomanometer for blood pressure measurement based on. The uncertainty of pulse blood pressure meter, usually also the uncertainty of blood pressure.
Specific detection methods are as follows:
Calm with blood pressure continuous measuring about 5 times, to observe the measured pulse number is consistent, the normal error should be +/-2 pulse number within ( arrhythmias except).
Four, confirm the electronic sphygmomanometer in measuring process is repeated compression
Good quality electronic sphygmomanometer, usually one that can measure the pressure. Only on rare occasions ( such as the external interference factors too much ), will appear two times pressure.
Specific detection and evaluation methods are as follows:
Calm with blood pressure continuous measuring about 5 times, if not two times pressure, it can determine the blood pressure meter in measurement of no problem.
If often appears two times pressure ( excluding the special circumstances listed above ), basically can determine the blood pressure meter in measurement problems.
Five, confirm the electronic sphygmomanometer measurement results of stability
Good quality electronic sphygmomanometer, repeatedly measured outcome will be relatively consistent.
Specific detection methods are as follows:
Calm with sphygmomanometer was measured continuously for 5 times and record the results of the results, largely determine the following:
The difference between 5mmHg within: very accurate
The difference between 6~10mmHg: basic accuracy
The difference between 11~15mmHg: not accurate
Is greater than the difference between 15mmHg: not very accurate
Suggestion: measured before the rest 15 minutes, each measurement time interval for 30~60 seconds.
More professional electronic blood pressure meter test method shall refer to the European Society of hypertension ESH clinical detection protocol or the United States of America 's AAMI AAMI/ANSI SP10:2002 -A1-2003-A2-2006 clinical detection protocol.
In 2009, the international organization for standardization launched clinical testing standard ISO81060-2:2009, this standard basically is by the AAMI protocol development.
Attach a separate statement: there is also a clinical detection protocol -- the British Hypertension Society ( BHS ) clinical detection protocol, once very famous, but because a lot of the BHS finds electronic blood pressure monitor in the United States of America problems without being recognized by the United States AAMI, so now in addition to Europe outside the UK, BHS basically has been replaced by the ESH.
