Description

technical field [0001] The invention relates to an electrocardiogram electrode used in electrocardiogram examination, specifically a test system for detecting performance indicators of electrocardiogram electrodes. Device technology field. Background technique [0002] Electrocardiogram examination is a commonly used medical measure in disease diagnosis and rescue. Through the observation of electrocardiogram, various arrhythmias, ventricular and atrial hypertrophy, myocardial infarction, myocardial ischemia and other diseases can be judged. When performing electrocardiogram examination, ECG electrodes must be used Contact with the human body to obtain the ECG signal, and the performance index of the ECG electrode itself is related to the accuracy of the ECG inspection result. [0003] At present, the performance testing of ECG electrodes in my country is mainly carried out according to the method provided in the pharmaceutical industry standard of the People's Republic of ...

[0003] At present, the performance testing of ECG electrodes in my country is mainly carried out according to the method provided in the pharmaceutical industry standard of the People's Republic of China YY / T0196-2005 "Disposable ECG Electrodes". In this method, different performance indicators are used. The method of separate detection, that is, a special device is used to detect each performance index, and each device must be equipped with an independent power supply, signal generator, display (oscilloscope) and corresponding processing circuit And other devices, which makes it necessary to use a lot of equipment when detecting ECG electrodes, and each equipment also requires different professionals to operate. This kind of equipment takes a long time to detect, which makes the whole process messy and complicated, which is not conducive to the systematic recording and preservation of the results; moreover, it is difficult to unify the standards of different professionals during the test, especially for different equipment due to different manufacturers. The output results are analog signals, while some output results are digital signals, resulting in differences in detection accuracy and inaccurate final results; as there are many performance indicators of ECG electrodes, there are many devices used in the detection process, so Also caused the detection cost is too high
