It is a characteristic method of mounting a portable electrocardiograph. In another aspect of the invention, the electrode of the electrocardiograph is closely fixed to the contact part of the living body at any time to detect a biological signal, and the data obtained by the detection is transmitted through a transmission means such as a mobile phone. It is a method of using a portable electrocardiograph characterized by analyzing, or analyzing data by mailing or bringing an electrocardiograph.

In the above invention, one of the electrodes may be made movable, or the induction electrodes may be provided at three or more places.
Adhesion in the invention, a known adhesive that is harmless to living organisms is applied, and if a release paper is attached to the upper surface of the adhesive, there is no fear of sticking to other objects while carrying, and if the electrode is covered with the release paper, the electrode There is also an advantage that protects.

In the case of the present invention, a printed circuit board is built in, circuits necessary for the printed circuit board are built in, a memory,
Since it is only necessary to incorporate other necessary parts and batteries, the total thickness can be made extremely thin, which is convenient for carrying and allows daily activities while wearing an electrocardiograph. , You can get an electrocardiogram in your daily life. Further, since the data can be transmitted by a mobile phone or a personal computer, a doctor at a remote place can decode the electrocardiogram in case of emergency, and can return to give an appropriate treatment. Further, by moving a part of the electrodes, not only the biological signal in the vicinity of the heart but also the biological signal in other parts can be captured and contribute to the comprehensive decoding.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, a plurality of electrodes are arranged on the outer surface of the case of an electrocardiograph in which a circuit capable of detecting and processing a biological signal in a flat case and a memory are incorporated.
The adhesive portion is provided.

Therefore, the case can be fixed to the living body only by abutting and adhering the adhesive portion of the case, and the electrodes can be surely brought into close contact with each other. In this case, the adhesive force is sufficient to hold the case and maintain the electrodes in close contact with each other so that the adhesive force does not come off or move even if the living body acts.

Since there are the above-mentioned mounting and functional characteristics,
It is possible to have a necessary patient carry it on a daily basis, and to have an electrocardiogram transmitted by an instruction or at a predetermined time period. For emergency patients, it is possible to collect the electrocardiogram from the first aid until the arrival at the hospital, or to send it at any time and receive an appropriate instruction from a doctor in a remote place by decoding the electrocardiogram.

Further, the opinions of a plurality of doctors scattered in remote areas or remote areas can be immediately heard.
