Electrocardio-electrode performance test system

Abstract

The invention provides an electrocardio-electrode performance test system which is easy and convenient to operate, efficient and low in detection cost, and can avoid errors caused by manual operation, improve the detection accuracy, and achieve various performance tests of an electrocardio-electrode. The system comprises a selection module, a function detection module and a control module which are connected in sequence. An electrode pair is connected with the selection module. The control module comprises a multi-channel analog-to-digital conversion module and a single-chip microcomputer which are connected. The single-chip microcomputer is connected with an upper computer through a USB interface, and the single-chip microcomputer is connected with the selection module. The function detection module comprises an electrode pair alternating current impedance detection module, an electrode pair voltage detection module, an electrode pair noise detection module, an electrode pair defibrillation overload detection module and an electrode pair bias current tolerance detection module. A plurality of selection switches are arranged in the selection module and are correspondingly connected with the function detection module. The multi-channel analog-to-digital conversion module is used for converting an analog signal sent by the function detection module into a digital signal and then sending the digital signal to the single-chip microcomputer.

Description

technical field [0001] The invention relates to the technical field of ECG electrodes, in particular to an ECG electrode performance testing system. Background technique [0002] ECG monitoring is widely used in clinical departments. It is a necessary equipment for critical patient monitoring and an important guarantee for diagnosis, rescue and treatment. It can detect changes and abnormal conditions of the patient's ECG in time, make a correct diagnosis, and take effective rescue measures quickly to save the patient from danger. As one of the important components of the ECG monitoring system, the performance of the ECG electrode is directly related to the accuracy of the monitored data, so the detection of its performance is also very important. At present, when testing ECG electrodes, more equipment is needed, and each equipment requires different professionals to operate. The time is also long, which makes the whole process messy and complicated, which is not conducive ...

Problems solved by technology

At present, when testing ECG electrodes, more equipment is needed, and each equipment requires different professionals to operate. The time is also long, which makes the whole process messy and complicated, which is not conducive to the systematic recording and preservation of results; and because it is difficult to unify the standards of different professionals in the test, there may also be errors in human operation, resulting in inaccurate final results; and Due to the many performance indicators of ECG electrodes, there are also many equipment used in the detection process, which also results in high detection costs.
