Apparatus for measuring biological signal

The present invention relates to a biosignal measuring device, and more particularly, to a biosignal measuring device that enables the measurement of the position of the conductive snap appropriately in response to the body of a subject detecting the biosignal.

When the muscles of the heart are active, electrical excitement occurs and an action potential of about 1㎷ is generated, and this is an electrocardiogram that is recorded as a waveform by electric current transmitted to the surface of the body.

Electrocardiogram measurements are widely used to detect, diagnose, and diagnose diseases, as well as to view healthy heart conditions or responses.

In particular, electrocardiograms are provided as important information in diagnosis of various arrhythmia and electrolyte abnormalities, coronary artery diseases such as angina pectoris and myocardial infarction, or investigation and confirmation of the presence of heart abnormalities during surgery.

Electrocardiogram measurement is based on the principle that the depolarization waveform spreads along the heart muscle in three dimensions because the heart is a three-dimensional structure, by attaching electrode patches at various locations in the body and measuring the voltage over time.

The conventional electrocardiogram measuring apparatus for electrocardiogram measurement includes an electrocardiogram measurement device equipped with an electrocardiogram measurement program and a wired cable connected to the electrocardiogram measurement device and attached to a subject's body.

On the other hand, between the one side groove (532a) and the other side projection groove (532b) is formed a curved curved portion 533 of the smooth surface form the projection (502) in one projection groove (532a) or the other projection groove (532b) It is possible to prevent the sliding bar 521 from sliding freely.

Meanwhile, in the first embodiment, although the conductive snap is provided on one side of the bottom surface of the bar-shaped main body, and the rotating bar is installed on the other side of the bottom, the sliding bar may be installed instead of the rotating bar.

Further, in the second or third embodiment, all conductive snaps are illustrated as being installed at the ends of the rotating bar or the sliding bar, but some conductive snaps are fixedly installed on the main body, or a rotating bar or the sliding bar is mounted on one main body. It may also be possible to mix.

In addition, although a triangular or Y-shaped main body is illustrated in the second embodiment or the third embodiment, it is a matter of course that the main body may be configured in a shape extending in a different shape of polygon or other direction.

Although the present invention has been described with reference to the preferred embodiments thereof with reference to the accompanying drawings, it will be apparent to those skilled in the art that many other obvious modifications can be made therein without departing from the scope of the invention. Accordingly, the scope of the present invention should be interpreted by the appended claims to cover many such variations.
