Description

ECG signal measuring device

The invention provides an ECG signal measuring device, in particular to a non-adhesive ECG signal measuring device with high concealment.

At present, China has gradually entered an aging society, and the proportion of the elderly population has increased year by year, and heart disease is one of the invisible killers of the silver-haired people. Among them, arrhythmia is a very common symptom in heart-related diseases, and monitoring of heart-related diseases is an important issue for the elderly. At present, the detection of heart rate/electrocardiogram is mainly monitored by an electrocardiogram detecting device. The conventional method is to stick a wet electrode containing an electrolyte to the chest, and as a connection between the skin and the machine, the heart rate/electrocardiogram is measured.

Since the wet electrode containing the electrolyte is used for a long time after use, it is easy for the user to feel uncomfortable such as allergies; in some cases, the electrode may be peeled off and then attached, and some Users may find it inconvenient to repeatedly apply the electrodes. Disadvantages such as those described above may result in the inability of heart-related monitoring devices to be used universally in home life.

In order to overcome the above shortcomings, in recent years, an electrocardiographic detecting device that is compact and portable can be developed.
