Contactless electrocardiogram measuring system

Abstract

The invention belongs to the technical field of medical equipment, and particularly relates to a contactless electrocardiogram measuring system. The contactless electrocardiogram measuring system comprises an electrocardiogram signal acquisition system and an upper computer software system, wherein the electrocardiogram signal acquisition system comprises a signal acquisition module, a signal processing module, a signal transmission module and a power supply module, and is used for acquiring, preprocessing and transmitting electrocardiogram signals of measured objects; the upper computer software system is a simple human-computer interaction interface for users, is used for extracting, processing, displaying and recording the acquired electrocardiogram signals, and can display intuitive electrocardiograms to doctors or the users; stored data can be used for data analysis, heart disease prediction and sleep analysis. The contactless electrocardiogram measuring system is convenient to use and suitable for long-term continuous electrocardiogram measurement; the system is made from low-power components, thereby saving energy and having low power consumption; the simple human-computer interaction interface is adopted during operation, the users can visually see clear electrocardiogram waveforms, and the data can be stored for later analysis.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a non-contact electrocardiogram measurement system. Background technique [0002] Cardiovascular disease is a class of diseases with high morbidity and mortality, which seriously threatens the life of human beings (especially the elderly). Although there are some advanced treatment methods, the mortality rate is still very high, and the survivors are basically unable to recover, and suffer from pain from time to time. Therefore, while improving the level of cardiovascular treatment, the prevention of cardiovascular diseases and the monitoring of patients with cardiovascular diseases are also particularly important. [0003] As an ECG signal that reflects important physiological parameters of the heart, its measurement and analysis is an effective way to prevent cardiovascular diseases or monitor patients. For example, ECG signals directly reflect various i...

Problems solved by technology

[0004] At present, the most widely used ECG acquisition electrodes are wet electrodes for passive measurement, such as Ag / Agcl electrodes. Although they can collect high-quality ECG signals, they have certain limitations, mainly reflected in: (1) It is troublesome to use , it is necessary to do some pretreatment on the skin where the electrode is placed, such as removing thick and rough hair and the cuticle of the skin; (2) Wiping alcohol or applying conductive paste may cause human allergies, especially babies and sensitive people; (3) It may cause panic and nervousness in patients, and indirectly affect the reliability of the measured ECG signal; (4) Electrodes cannot be used multiple times, and the measurement cost is high

The above-mentioned limitations of the traditional ECG measurement system restrict its development to long-term monitoring and daily monitoring
