Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention enables the electrodes to be placed close to a predetermined position on the body of a patient when the electrodes are fixed to the body of the patient for recording an electrocardiogram by putting the electrodes on the patient. Regarding the clothing accessories.

[0002]

2. Description of the Related Art As is well known, conventionally, in order to record an electrocardiogram, a method of sticking individual electrodes to the body of a patient with adhesive tape in correspondence with the position of inducing electromotive force of the heart is adopted. Has been done.

Incidentally, among cardiac diseases, angina pectoris, myocardial infarction, arrhythmia and the like cause changes in the electrocardiogram only when symptoms occur, and therefore recording the electrocardiogram at that time is indispensable for confirming the diagnosis. However, in these diseases, changes in the electrocardiogram are transient, and it is often difficult to induce seizure even in a provocation test at the time of examination, and it often takes time to confirm the initial diagnosis.

For this reason, in order to record an electrocardiogram when a symptom appears, care must be taken so that the electrocardiogram can be recorded on the spot at the time of an attack in daily life.
A time electrocardiography test has been performed.

[0005]

According to the conventional 24-hour electrocardiogram recording and inspection method, as a matter of course, if no seizure occurs within 24 hours while the patient is wearing the recorder, 2
The 4-hour record itself becomes meaningless. The recording time can be extended by replacing the recording tape, etc., but in the case of 24-hour electrocardiogram or ECG monitoring in a ward, the electrode is conventionally attached to the patient's body with adhesive tape, so the skin There is a risk of rash or itching, which causes great pain to the patient. Further, in a long-time recording inspection, the work is difficult because the adhesive tape is peeled off due to sweat or dirt. On the other hand, in the case of recording an electrocardiogram in an electrocardiographic examination room, it is a method of sandwiching a large clip-type electrode on a limb or adsorbing a sucker-type electrode on the chest so that the purpose of the invention is to continuously monitor it. Needless to say, it is not suitable for electrocardiographic examination. Furthermore, since the recording itself only makes two or three simple bipolar leads, there are many unsuitable points, such as a decrease in objectivity for ST segment analysis, which is important for the diagnosis of angina.

[0006]

As a result of various studies, the present inventor has found that, in order to solve the above problems, an electrode is attached to a sheet-shaped clothing accessory such as underwear, and a patient wears such clothing. Wearing a tool and spending the time until a seizure is significantly easier than the conventional method of sticking electrodes with adhesive tape or sandwiching them with clips, and especially 12-lead We have found that there is a special effect in waiting for the continuous recording of the electrocardiogram, and the patient's pain is greatly reduced, which is advantageous. However, in constructing such a clothing accessory, it is necessary to consider the following conditions.

First, according to the experience of the present inventor, it is expected that some patients will have only a few strokes per month, and that a record examination for a considerably long period of time will sometimes have to be performed. Therefore, it is necessary for the clothing accessory to minimize the burden on the patient when wearing the clothing, and it is required not to press the body during the waiting period before the attack or to cause a feeling of strangeness.

Second, at the time of an attack, the relationship between the electrodes and the body must be maintained in a state that enables quick and good recording.

Thirdly, it should be easy to put on and take off the body in consideration of taking off the clothing accessories when taking a bath.

[0010] Therefore, the present inventor, while the patient can wear the clothing in a relaxed state while waiting, when the seizure or the like occurs suddenly and an electrocardiogram recording must be performed, the electrode is quickly applied to the body surface. It has been found that it is advantageous to be configured so as to be in close contact with the site, and the present invention can be achieved by performing such a state change of the clothing accessory by a balloon portion which is inflated through the supply of fluid. It was made.

Thus, the present invention constitutes the first means.
