It is especially convenient and helpful for patients with cardiovascular diseases who need to record the ECG signal for a long time.

As we all know, the physical activity of the body produces specific physiological electrical signals on the surface of the body. With the continuous advancement of medical technology, the relationship between many diseases and physiological signals has been studied in detail.

At present, measurement patches can be used to stick to specific positions on the body surface, such as the head, chest, abdomen, back, and extremities, and use non-invasive methods to measure various physiological electrical signals, such as brain wave signals (EEG), Electromyographic signal (EMG), neuroelectric signal (ENG), retinal electrical signal (ERG), gastric electrical signal (EGG), neuromuscular electrical signal (ENMG), cerebral cortex electrical signal (ECoG), eyeball electrical signal (EOG) And the nystagmus electrical signal (ENG) and so on. In particular, abnormal blood pressure and heartbeat often lead to cardiovascular diseases. Therefore, it is quite common to use physiological signal measuring devices to measure heart rhythm-related information, and can be used as an indicator of health status.

In the conventional technology, the general electrical signal measurement patch is to set a conductive metal sheet and a label on the adhesive layer of the foam glue, and use the electrode sheet to stick the bottom of the foam glue, and then stick the conductive glue. Under the electrode sheet. In addition, the conductive metal sheet is electrically connected to the electrode sheet, and when in use, the conductive glue must be used to directly contact the surface of the human body, and then the conductive metal sheet must be connected to an external device with a signal wire. The electrode sheet can measure the electrical signal on the surface of the human body through the conductive glue, and use the conductive metal sheet to transmit to an external device for specific analysis and display relevant physiological waveforms, data and status.

Although the relevant industry has tried their best to make the measurement patch into a thin sheet, which can be directly attached to the human body and can be easily peeled off, which makes it very convenient to use. However, the disadvantage of the conventional technology is that each patch can only measure electrical signals at a single location, and in actual applications, it is often necessary to measure multiple locations, resulting in patches and connecting lines all over the body, which are easy to tear. This causes problems for medical staff or patients in their actions.

Therefore, the industry has already developed a portable measurement patch that can be directly attached to the body for measurement without using any connecting wires, which greatly improves the convenience of operation. However, this kind of measurement patch is not waterproof, so it is easy to detach after sweating, such as exercise, especially not suitable for bathing. Therefore, the user must remove the measurement patch before exercising or taking a bath, which is inconvenient to use, and is only suitable for static use and cannot be used for a long time. Therefore, not only the use environment is limited, but the use time is not long enough.

According to the physiological signal monitoring device described in claim 1, wherein the at least two electrodes have an end extending outward, and the lower patch layer has two holes corresponding to the end, and the at least two electrodes The end is connected to the skin through the two holes for sensing the ECG signal, wherein the hole of the lower patch layer is tightly connected with the corresponding end to have a waterproof effect, for example, the hole and the corresponding The end is located between the two through a double-sided adhesive layer, and is tightly joined. According to the physiological signal monitoring device described in item 1 of the scope of patent application, the upper patch layer has waterproof properties, and the outer edge of the upper patch layer extends beyond the lower patch layer to form a continuous discontinuity The interrupted area is used to completely adhere to the skin to form an externally enclosed area for protecting the bottom of the waterproof housing and the lower patch layer, and one of the at least two electrodes only extends from the inside of the waterproof housing to the outside It extends to an area where the upper patch layer and the lower patch layer overlap, but does not extend to an area where only the upper patch layer is distributed. A physiological signal monitoring device includes; a waterproof housing, which is a closed body; an ECG signal processing unit, which is arranged in the waterproof housing; an upper patch layer with an upper surface and a lower surface, the lower surface In order to have adhesiveness, the waterproof housing is placed on the upper surface of the upper patch layer; the lower patch layer has an upper surface and a lower surface, and the lower surface is adhesive for attaching to a skin. The lower patch layer is placed on the lower surface of the upper patch layer; and At least two electrodes are located between the upper patch layer and the lower patch layer, each of the electrodes is electrically coupled to the ECG signal processing unit, wherein the bottom of the waterproof housing and the upper patch layer There is at least one gap between the two surfaces to facilitate the evaporation of water and gas. According to the physiological signal monitoring device described in item 6 of the scope of patent application, the upper patch layer extends laterally beyond the lower patch layer to form an outer edge of the upper patch for attaching to the skin, and the upper patch layer The patch layer and the lower patch layer have air permeability and moisture permeability, and the air permeability and moisture permeability of the outer edge of the upper patch are higher than the part where the upper patch layer and the lower patch layer are combined. According to the physiological signal monitoring device described in item 6 of the scope of patent application, wherein the upper patch layer has a plurality of pore structures, and the pore structure of the upper patch layer is visible to the naked eye and has air permeability and moisture permeability, or The lower patch layer has a plurality of pore structures, and the pore structure of the lower patch layer is visible to the naked eye and has air permeability and moisture permeability. The physiological signal monitoring device according to item 6 of the scope of patent application further includes a base with an upper surface and a lower surface, and is arranged between the upper patch layer and the lower patch layer, or is located The upper patch layer or the lower patch layer is used to fix and carry the waterproof housing, and the base and the waterproof housing are in partial contact. The physiological signal monitoring device according to item 6 of the scope of patent application, wherein the at least one gap is a penetrating gap, which penetrates a part between the bottom of the waterproof housing and the upper surface of the upper patch layer to facilitate water Evapotranspiration.
