ECG acquisition circuit, device, method and system

Abstract

The invention discloses an electrocardiogram acquisition circuit, equipment, method and system, belonging to the field of medical equipment. The ECG acquisition circuit includes: a wireless transmission circuit configured to receive a first ECG signal sent by a second ECG acquisition device, the first ECG signal includes a first ECG voltage and a first collection of the first ECG voltage time; the ECG electrode is configured to detect the electrical signal on the human skin; the acquisition circuit is configured to collect the electrical signal detected by the ECG electrode to obtain a second ECG voltage; the control circuit is configured to collect the electrical signal based on the acquisition The second electrocardiographic voltage obtained by the circuit generates a second electrocardiographic signal, and the second electrocardiographic signal includes the second electrocardiographic voltage and the second acquisition time of the second electrocardiographic voltage; based on the first acquisition time and the second acquisition time, the wireless The transmission circuit receives the first ECG signal and the second ECG signal to obtain an ECG index signal. The comfort of the user wearing the ECG collection device is improved, so that the user can move freely.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an electrocardiogram acquisition circuit, equipment, method and system. Background technique [0002] In daily ECG monitoring, ECG acquisition system can effectively monitor important indicators such as heart rate and cardiac rhythm of patients, and is a necessary equipment for monitoring diseases such as arrhythmia, myocardial ischemia and early coronary heart disease. The ECG electrode equipped with the ECG acquisition system collects the electrical signals generated by the heart activity, and the contraction of the myocardium in each heartbeat will cause changes in the electric charge on the surface of the human skin. What ECG electrodes collect is the electrical signals generated by charge changes in such activities. [0003] The ECG acquisition system usually includes a plurality of ECG electrodes, which need to be placed on the limbs, chest, abdomen, etc. of the human body...

AI Technical Summary

Problems solved by technology

[0004] Since there are multiple ECG electrodes, there are many transmission lines required to connect each ECG electrode to the terminal. These transmission lines are worn on the patient at the same time. On the one hand, the comfort of the patient wearing the ECG acquisition device is low. On the one hand, it affects the behavior of patients
