Electrocardio-electrode electrical performance tester

Abstract

The invention provides an electrocardio-electrode electrical performance tester. The tester comprises a main machine, an external power source and connecting wires, the main machine is connected with an electrode slice through the connecting wires, and the external power source used for supplying power to the main machine is connected with the main machine; the main machine comprises an alternating current impedance detection circuit, a noise detection circuit, an offset detection circuit, a four-way analog switch, a display sequence circuit, a defibrillation sequence circuit, a current tolerance sequence circuit, a first exciting circuit, a second exciting circuit and a third exciting circuit. According to the tester, detection of alternating current impedance, offset voltage, internal noise, bias current tolerance and defibrillation performance of the electrode slice can be conducted. Compared with traditional manual detection, the tester has multiple functions. Due to the fact that the external power source is adopted by the electrocardio-electrode electrical performance tester, the whole size of the electrocardio-electrode electrical performance tester is greatly reduced, so that transportation is convenient; meanwhile, interference easily caused by an power source which is too close to the main machine is avoided, so that interference on detection results during detection is avoided.

Description

technical field [0001] The invention relates to the technical field of electrocardiographic electrodes, in particular to an electrocardiographic electrode electrical performance tester. Background technique [0002] ECG monitoring is a diagnostic method widely used in various intensive care units and clinical diagnosis and treatment operating conditions. In order to achieve the purpose of ECG monitoring, in addition to having ECG monitoring equipment, it is also necessary to paste ECG electrodes on different parts of the patient's body to collect the patient's ECG signal. Since the ECG electrodes are in direct contact with the human skin, the ECG electrodes need to be sent to a testing agency for testing before leaving the factory to ensure the safety and reliability of the ECG electrodes. However, most of the instruments and meters that do not detect ECG electrodes currently use manual detection. Manual detection has the following disadvantages: 1. There are few detection ...
