An electrocardiogram is a drawing of a wave curve showing the action current and action potential difference according to the contraction of the heart. Electrocardiograms are generally represented by several electrocardiograms using an electrocardiogram and are very important for the diagnosis of heart disease.

In order to generate an electrocardiogram using an electrocardiogram, it is necessary to attach an electrode for an electrocardiogram to the skin of a measuring object such as a human body or an animal, and to obtain and amplify a weak electric signal generated in the heart of the measuring object.

Typically, three electrocardiogram electrodes need to be in contact with the skin of the measurement object to obtain an electrical signal, and the electrode attachment position may vary according to the physical condition of the measurement object to obtain a clear signal.

The ECG electrode 300 is coupled to the first to third electrode coupling holes 225, 235, and 215.

In more detail, the electrocardiograph electrode 300 is formed on a base portion 302 formed in a plate shape and on one side of the base portion 302 and can be inserted (inserted) into the electrode coupling holes 225, 235, and 215. Insertion protrusion 304 having a and the electrode portion 306 is formed on the other side of the base portion 302 and has a protruding shape so as to be in contact with the skin of the subject (B).

Preferably, the base portion 302, the insertion protrusion 304, and the electrode portion 306 are formed of a conductive material and are integrally formed. For example, the conductive material may be a conductive silicone rubber material capable of elastic deformation, but is not necessarily limited thereto.

Preferably, the first band 220 and the second band 230 is formed of a material capable of elastic deformation. For example, the elastic deformable material may be a silicone rubber material capable of elastic deformation, but is not necessarily limited thereto.

In addition, preferably, the first and second

conductive parts

223 and 233 are formed of a conductive material capable of elastic deformation. For example, the conductive material may be a conductive silicone rubber material capable of elastic deformation, but is not necessarily limited thereto. The first and second

conductive parts

223 and 233 made of such a material are formed in a long plate shape and are attached to the inside of the first band 220 or the second band 230 and the electrode coupling holes 225, 235 and 215.

The electrode unit 306 of the electrocardiograph electrode 300 may have various deformation forms in order to detect a more accurate electrocardiogram signal according to the size of the body B, the presence or absence of hair, and the length of hair.

For example, the electrode part 306 may be formed in a form in which a plurality of electrode pins 306 ′ protrude from the other side of the base part 302 (FIGS. 7A and 7B). Since the shape of the plurality of electrode pins 306 ′ may make a part of the plurality of pins touch the skin of the subject B, the signal non-detection fear may be the lowest.

As another example, the electrode part 306 may be formed in a form in which the electrode piece 306 ″ having a sine wave side cross section is protruded from the other side of the base part 302 (FIG. 7 (c)). The electrode pins 306 ', such as (a) and (b) of FIG. 7 are advantageous in terms of signal detection, but are easy to stimulate the skin of the subject B. It may be difficult to use if the person is sensitive to stimulation or animals. In consideration of such a case, an electrode piece 306 ″ having a lateral sinusoidal side cross section may be used. When this form is applied, there is an advantage of ensuring a wide contact area while having less skin irritation of the subject B. Unexplained reference numeral 306a '' denotes a recess of a sinusoidal cross section.

As another example, the electrode part 306 may be formed in a shape in which an electrode wall 306 ′ ″ having a planar shape having a lattice shape protrudes from the other side of the base part 302 (FIG. 7). (d)). This configuration provides an advantage of making the contact area larger than that of the structure of FIG. 7C while having a lower concern about skin irritation than the electrode pins 306 'of FIGS. 7A and 7B. Unexplained reference numeral 306a '' 'denotes a bottom portion in the middle of the electrode wall 306' '' having a lattice planar shape.

Preferably, when the electrocardiograph electrode 300 is made of a soft elastic material (eg, a silicone rubber material) having an appropriate hardness, an electrode pin 306 ′ form as shown in FIGS. 7A and 7B. Even if produced as a skin irritation may be formed small.

On the other hand, the electrocardiograph electrode 300, the electrode having a variety of electrode area or height in the form of a set in order to detect a more accurate ECG signal according to the body size of the subject (B), hair presence, hair length conditions Can be configured.

For example, the ECG electrode 300 may be provided with a plurality of electrodes having different areas of the base portion 302. For example, in the case of a large to-be-measured body (B) as shown, a large-area electrode can be combined and used as shown in FIG. In this case, as shown in FIG. 7B, electrodes having a small area can be combined and used.

As another example, the electrocardiograph electrode 300 may be provided with a plurality of electrodes having different heights h of the electrode unit 306. For example, in the case of the measurement target B having hairs, the electrode having a high height h of the electrode unit 306 may be used in combination, and in the case of the measurement target B having no hair, the electrode portion 306 may be used. Can be used in combination with an electrode having a low height h.

The power supply may be configured of a replaceable or rechargeable battery, and the communication processor may selectively apply various known communication methods. The ECG module 100 may also be provided with a known GPS module, a temperature sensor, or the like, and may transmit position and temperature data.

The ECG signal measured as an electrical signal through the

electrode terminals

112, 114 and 116 (module contact) is converted into digital data through the data management unit and transmitted to the management server 4000 through the communication processing unit. The power supply supplies power for this signal measurement and communication process. The power supply may be a conventional battery.

In order to record and manage ECG data transmitted from the ECG module 100 for each user, the management server 4000 may match an ECG registration module 4021, a user information registration module 4022, ECG data, and user information. A database 4023 for recording management, a management module 4024 for overall management control of the server, and the like may be provided.

For example, the management server 4000 may periodically receive and manage electrocardiogram data by requesting the electrocardiogram module 100 of the target object based on a preset management program, and manage the web or app (APP) service. It can also be provided based on the request of the administrator set in advance through.
