Description

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. The present invention relates to a structure for attaching an electrode to the clothing accessory.

[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.

Fourth, in preparation for a record inspection for a long period of time, it is necessary that the clothing accessory can be repeatedly worn while maintaining a clean state by ordinary washing.

Fifth, while the above-mentioned structure is designed so that it can be worn repeatedly, the clothing accessory itself needs to be frequently washed due to sweat, dirt, etc., and therefore must be understood as a consumable item to some extent. However, since the electrodes are expensive, it must be considered that they can be used for a long period of time.

[0012] Therefore, the present inventor, while waiting, can be comfortably worn by the patient like ordinary shirts and vests, and can be repeatedly worn while being kept clean by washing. When a seizure or the like suddenly occurs, and electrocardiographic recording must be performed, it has come to propose a clothing accessory configured so that the electrode can be brought into close contact with a target site on the body surface promptly. The purpose is to satisfy the fifth point.

Thus, the present invention is configured as the first means that the knitted fabric in the form of a sheet is used as the material, and the electrode body is provided corresponding to the position for inducing the electromotive force of the heart when worn. In the accessory, the electrode body is attached to the seat portion of the clothing accessory through a detachable attachment means.

Specifically, the electrode body includes a head formed of electrodes, and a flange arranged substantially parallel to the head through a neck protruding from the head, A slit is formed so that the seat portion can pass through the head of the electrode body in a removable manner, the neck portion of the electrode body is inserted through the slit, and the head portion of the electrode body and the flange hold the seat portion of the clothing accessory. By this, a detachable attachment means can be configured.
