Electrocardiogram monitoring chest belt with motion artifact inhibition function

Abstract

The invention discloses an electrocardiogram monitoring chest belt with a motion artifact inhibition function. The chest belt takes a flexible high-elasticity fabric as a base layer, two flexible fabric electrocardiograph dry electrodes, two pairs of auxiliary dry electrodes and a reference electrode are fixed on the base layer, the two flexible fabric electrocardiograph dry electrodes are horizontally distributed in the middle of the base layer, each pair of dry electrodes include upper auxiliary dry electrodes and lower auxiliary dry electrodes, the upper auxiliary dry electrodes and the lower auxiliary dry electrodes are symmetrically distributed on the upper side and the lower side of each flexible fabric electrocardiograph dry electrode, the two upper auxiliary dry electrodes are connected by the aid of a fiber resistor, the reference electrode is positioned at horizontal center between the two flexible fabric electrocardiograph dry electrodes, signal lines of each electrode penetrate the base layer and are connected with a signal processing module fixed on the other side of the base layer, the signal processing module is used for receiving signals of the electrodes and processing the signals to obtain electrocardiogram signals, and special woven seamless pressure adhesive is hollowed according to the shapes of the electrodes and adhered with the base layer to serve as aninsulation shielding layer. By the aid of the chest belt, motion artifacts can be effectively inhibited.

Description

technical field [0001] The invention belongs to the technical field of electrocardiogram monitoring, and more specifically relates to a chest belt for electrocardiogram monitoring with the function of suppressing motion artifacts. Background technique [0002] In today's society, the number of patients with chronic diseases is increasing. Cardiovascular diseases, especially heart disease, are prevalent in the population, up to 19.6%. As the population ages, people increasingly suffer from chronic cardiovascular diseases such as heart disease, and medical costs continue to rise. Electrocardiogram is the main basis for the treatment of cardiovascular diseases. It has the advantages of reliable diagnosis, easy operation, and no damage to the health of patients. Routine medical testing is usually carried out in specific inspection equipment and environments in hospitals, requiring patients to lie down statically for detection and analysis, which has disadvantages such as incap...

Problems solved by technology

Conventional disposable ECG electrodes usually have the following problems in the process of collecting dynamic ECG signals: (1) Disposable ECG electrodes are wet electrodes and contain conductive gel. Long-term use under dynamic conditions will cause the gel to harden. The quality of the collected ECG signal deteriorates; (2) long-term use of conductive gel will cause skin allergies, inflammation, and discomfort in some patients; (3) it is easy to fall off, and it is not suitable for real-time measurement in the state of exercise. More

[0004] At present, the biggest problem facing the monitoring of ECG signals under dynamic conditions is the interference of motion artifacts. Motion artifacts are the noise of ECG signals generated during exercise. This is due to the interaction between electrodes and skin surfaces when the body is moving or moving. effect, causing the contact interface to be unstable, resulting in the redistribution of surface charges and generating noise

Interference noise will make the normal ECG signal unable to be recognized by the analysis algorithm, resulting in deviations in the final analysis results
