Description

Technical Field

[0001] This application relates to the technical field of medical devices, and particularly to an electrode patch for an electrocardiogram detection device and an electrocardiogram detection device. Background Art

[0002] Ambulatory electrocardiogram is the gold standard for clinical screening and diagnosis of arrhythmias. However, arrhythmias are transient and sporadic. Due to the short attack time and infrequent attacks, it is often difficult for traditional 24-hour or 48-hour ambulatory electrocardiograms to capture abnormal electrocardiogram segments.

[0003] Prolonging the ambulatory electrocardiogram monitoring time can improve the detection rate of arrhythmias. The detection rate of continuous 7-day monitoring for multiple arrhythmias is much higher than that of 24-hour or 48-hour ambulatory electrocardiogram monitoring.

[0004] Currently, ambulatory electrocardiogram recorders on the market generally consist of a main unit and lead wires, and use disposable electrocardiogram electrodes. The main unit is relatively large in size and is worn in a cross-body or waist-mounted manner, resulting in poor comfort.

[0005] Among them, disposable electrodes are adhesively attached to the skin surface for a long time for electrocardiogram monitoring. However, existing disposable electrodes are prone to skin allergies. If disposable electrocardiogram electrodes are used for a long time, the adhesives on the electrode patches and the high-concentration electrolytes in the conductive gels can cause skin allergies and contact dermatitis. Moreover, the risk of skin allergies for disposable electrocardiogram electrodes is positively correlated with the pasting time, and the incidence rate is higher with longer time. In addition, the conductive gels on disposable electrodes are prone to falling off when sweating a lot, which will cause poor contact and thus affect the acquisition of electrocardiogram signals.
