[0002] Clinical observations have found that arrhythmias are often sporadic, with no fixed pattern in the time and frequency of occurrence. Generally, long-term monitoring is required to obtain meaningful data. In order to meet the needs of continuous ECG monitoring, dynamic ECG technology has emerged, such as the typical Holter ECG device. However, its further development has been limited by many factors, such as its large and heavy host, wired transmission, and insufficient remote management.
[0003] With the rapid development of microelectronic communication technology, wireless dynamic ECG monitoring technology has begun to enter the public's field of vision, such as ECG electrodes. ECG electrodes are generally small and portable and can perform ECG monitoring. In resting monitoring, ECG electrodes usually need to contact the skin through dry electrodes to collect and analyze ECG signals. However, when the dry electrodes are in contact with the skin for monitoring, the operator needs to continuously apply a conductive medium on the skin layer, which is cumbersome. The operator sometimes forgets to apply it, making it impossible to keep the dry electrodes moist during the period when the dry electrodes collect ECG signals, resulting in poor conduction between the dry electrodes and the skin, and poor stability of the ECG signals collected by the dry electrodes.

It can squeeze the output conductive medium to the dry electrodes to moisturize the dry electrodes during the time period when dry electrodes collect ECG signals, so that the conduction between the dry electrodes and the skin layer is better, which not only improves the stability of ECG signals collected by dry electrodes, but also prolongs the time for dry electrodes to collect ECG signals.

It can squeeze and output the conductive medium to the dry electrode 1 to moisturize the dry electrode 1 during the time period when the dry electrode collects ECG signals, so that the dry electrode 1 has a better conduction effect with the skin layer 5, which not only improves the stability of the dry electrode 1 in collecting ECG signals, but also prolongs the time for the dry electrode 1 to collect ECG signals.
[0023] Preferably, the conductive medium enters the sponge layer 3 by immersion or squeezing, and the sponge layer 3 is saturated with the conductive medium. The conductive medium is preferably a conductive liquid or gel-like liquid medium such as alcohol or a coupling agent.

[0025] The above embodiment has a simple structure and is easy to operate.
