Low-power portable electrocardiograph monitoring system

Abstract

The invention relates to a low-power portable electrocardiograph monitoring system, and belongs to the field of portable human-body electrocardiograph monitoring. The low-power portable electrocardiograph monitoring system comprises an electrocardio-electrode, a lead wire, an electrocardiosignal conditioning circuit, a single chip control circuit, a low-power bluetooth circuit, a rechargeable lithium battery, a power supply management circuit, a smart phone and a server. According to the low-power portable electrocardiograph monitoring system, right-leg driving, active power filtering, double-instrument operational amplifier and digital smooth filtering are adopted, an electrocardiosignal is effectively extracted, an R-wave calculated heart rate is accurately detected by adopting a differential threshold method, a real-time electrocardiogram is drawn by utilizing the smart phone, electrocardiogram data can be transmitted to the server, and a doctor can examine and analyze the electrocardiogram data at the server. Low-power design is adopted, the size is small, and the low-power portable electrocardiograph monitoring system is suitable for crowds needing to pay attention to the self electrocardio situations whenever and wherever.

Description

technical field [0001] The invention relates to a low-power portable ECG monitoring system, which belongs to the field of portable human body ECG monitoring. Background technique [0002] With the changes in people's work, lifestyle, eating habits and population aging, the incidence of heart disease in my country is increasing year by year. The electrocardiogram can reflect the electrical activity process of the human heart, and has important reference value for the basic functions of the heart and its pathological research. It can analyze and identify various arrhythmias, and can also reflect the damage of the myocardium and the functional structure of the atria and ventricles. . Therefore, ECG monitoring is becoming more and more important. For people who already suffer from heart disease, they need to monitor their ECG anytime and anywhere and give feedback to the doctor in time. [0003] At present, the existing ECG equipment in the hospital is bulky, consumes a lot of...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing ECG equipment in the hospital is bulky, consumes a lot of power, is expensive, and requires professionals to operate proficiently, which is not suitable for the above-mentioned people.

Existing portable monitoring systems, in terms of ECG signal extraction, some use integrated ECG acquisition chips, signal amplification and filter parameters are not easy to adjust, so that the ECG extraction effect is not good enough; others use discrete components to build ECG acquisition circuits, Interference processing is not good, especially interference such as myoelectricity and baseline drift, and the waveform is poor, so there will be problems with abnormal prompts and heart rate calculations

In terms of power consumption, the existing portable ECG monitoring system does not adopt a low-power design, and is bulky, making it difficult to perform ECG monitoring anytime, anywhere.

Moreover, existing portable monitoring systems do not have the function of feeding back ECG data to doctors, and most of them only support single-platform smart phones
